Read the passage through 131carefully before making your choices. Each choice in the bank is132identified by a letter. Please mark the corresponding letter for each 133item on Answer Sheet 2 with a single line through the centre. You may 134not use any of the words in the bank more than once.135A rat or pigeon might not be the obvious choice to tend to someone 136who is sick, but these creatures have some 26 skills that could help the 137treatment of human diseases.1386 精品.资料Pigeons are often seen as dirty birds and an urban 27 , but they 139are just the latest in a long line of animals that have been found to 140have abilities to help humans. Despite having a brain no bigger than the 14128 of your index finger, pigeons have a very impressive 29__ memory. 142Recently it was shown that they could be trained to be as accurate as 143humans at detecting breast cancer in images.144Rats are often 30 with spreading disease rather than 31 it, but 145this long-tailed animal is highly 32 . Inside a rat's nose are up to 1,000 146different types of olfactory receptors （嗅觉感受器）, whereas humans 147only have 100 to 200 types. This gives rats the ability to detect __33 148smells. As a result, some rats are being put to work to detect TB（肺149结核）. When the rats detect the smell, they stop and rub their legs to 15034 a sample is infected.151Traditionally, a hundred samples would take lab technicians more 152than two days to 35 , but for a rat it takes less than 20 minutes. This 153rat detection method doesn't rely on specialist equipment. It is also 154more accurate — the rats are able to find more TB infections and, 155therefore, save more lives.156A) associated I) slight157B) examine J) specify158C) indicate K) superior159D) nuisance L) suspicious160E) peak M) tip161F) preventing N) treated162G) prohibiting O) visual163H) sensitive1647 精品.资料Section B165Directions: In this section, you are going to read a passage with 166ten statements attached to it. Each statement contains information given 167in one of the paragraphs. Identify the paragraph from which the168information is derived. You may choose a paragraph more than once. Each 169paragraph is marked with a letter. Answer the questions by marking the 170corresponding letter on Answer Sheet 2.171Do In-Class Exams Make Students Study Harder?172Research suggests they may study more broadly for the unexpected 173rather than search for answers.174[A] I have always been a poor test-taker. So it may seem rather 175strange that I have returned to college to finish the degree I left undone 176some four decades ago. I am making my way through Columbia University, 177surrounded by students who quickly supply the verbal answer while I am 178still processing the question.179[B] Since there is no way for me to avoid exams, I am currently 180questioning what kind are the most taxing and ultimately beneficial. I 181have already sweated through numerous in-class midterms and finals, and 182now I have a professor who issues take-home ones. I was excited when I 183learned this, figuring I had a full week to do the research, read the 184texts, and write it all up. In fact, I was still rewriting my midterm 185the morning it was due. To say I had lost the thread is putting it mildly. 186[C] As I was suffering through my week of anxiety, overthinking 187the material and guessing my grasp of it, I did some of my own polling 188among students and professors. David Eisenbach, who teaches a popular 189class on U.S. presidents at Columbia, prefers the in-class variety. He 190believes students ultimately learn more and encourages them to form study 191groups. “That way they socialize over history outside the class, which 192wouldn’t happen without the pressure of an in-class exam,” he explained, 1938 精品.资料“Furthermore, in-class exams force students to learn how to perform 194under pressure, and essential work skill.”195[D] He also says there is less chance of cheating with the196in-class variety. In 2012, 125 students at Harvard were caught up in a 197scandal when it was discovered they had cheated on a take-home exam for 198a class entitled “Introduction To Congress.” Some colleges have what 199they call an “honor code,” th ough if you are smart enough to get into 200these schools, you are either smart enough to get around any codes or 201hopefully, too ethical to consider doing so. As I sat blocked and clueless 202for two solid days, I momentarily wondered if I couldn’t just call an 203expert on the subject matter which I was tackling, or someone who took 204the class previously, to get me going.205[E] Following the Harvard scandal, Mary Miller, the former dean 206of students at Yale, made an impassioned appeal to her school’s207professors to refrain from take-hone exams. “Students risk health and 208well being, as well as performance in other end-of-term work, when faculty 209offers take-home exams without clear, time-limited boundaries,” she 210told me. “Research now shows that regular quizzes, short es says, and 211other assignments over the course of a term better enhance learning and 212retention.”213[F] Most college professors agree the kind of exam they choose 214largely depends on the subject. A quantitative-based one, for example, 215is unlikely to be sent home, where one could ask their older brothers 216and sisters to help. Vocational-type classes, such as computer science 217or journalism, on the other hand, are often more research-oriented and 218lend themselves to take-home testing. Chris Koch, who teaches “History 219of Broadcast Journalism” at Montgomery Community College in Rockville, 220Maryland, points out that reporting is about investigation rather than 221the memorization of minute details. “In my field, it’s not what you 222know—it’s what you know how to find out,” says Koch. “There is way 223too much information, and more coming all the time, for anyone to remember. 2249 精品.资料I want my students to search out the answers to questions by using all 225the resources available to them.226[G] Students’ test-form preferences vary, too, often depending 227on the subject and course difficulty. “I prefer take-home essays because 228it is then really about the writing, so you have time to edit and do more 229research,” says Elizabeth Dresser, a junior at Barnard. Then there is 230the stress factor. Francesca Haass, a senior at Middlebury, says, “I 231find the in-class ones are more stressful in the short term, but there 232is immediate relief as you swallow information like mad, and then you 233get to forget it all. Take-homes require thoughtful engagement which can 234lead to longer term stress as there is never a moment when the time is 235up.” Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even 236considers take-homes true exams. “If you understand the material and 237have the ability to articulate (说出) your thoughts, they should be a 238breeze.”239[H] How students ultimately handle stress may depend on their 240personal test-taking abilities. There are people who always wait until 241the last minute, and make it much harder than it needs to be. And then 242there those who, not knowing what questions are coming at them, and having 243no resources to refer to, can freeze. And then there are we rare folks 244who fit both those descriptions.245[I] Yes, my advanced age must factor into the equation (等式), 246in part because of my inability to247access the information as quickly. As another returning student 248at Columbia, Kate Marber, told249me, “We are learning not only all this information, but250essentially how to learn again. Our251fellow students have just come out of high school. A lot has 252changed since we were last in25310 精品.资料school.”254[J] If nothing else, the situation has given my college son and 255me something to share, When I256asked his opinion on this matter, he responded, “I like in-class 257exams because the time is258already reserved, as opposed to using my free time at home to 259work on a test,” he responded.260It seems to me that a compromise would be receiving the exam 261questions a day or two in262advance, and then doing the actual test in class the ticking clock 263overhead.264[K] Better yet, how about what one Hunter College professor 265reportedly did recently for her final266exam: She encouraged the class not to stress or even study, 267promising that, “It is going to be a268piece of cake.” When the students came in, sharpened pencils 269in hand, there was not a blue270book in sight. Rather, they saw a large chocolate cake and they 271each were given a slice.27236. Elderly students find it hard to keep up with the rapid 273changes in education.27437. Some believe take-home exams may affect students'275performance in other courses.27638. Certain professors believe in-class exams are ultimately 277more helpful to students.27811 精品.资料39. In-class exams are believed to discourage cheating in exams. 27940. The author was happy to learn she could do some exams at home. 28041. Students who put off their work until the last moment often 281find the exams more difficult than282they actually are.28342. Different students may prefer different types of exams. 28443. Most professors agree whether to give an in-class or a 285take-home exam depends on type of286course being taught.28744. The author dropped out of college some forty years ago. 28845. Some students think take-home exams will eat up their free 289time.290Section C291Directions: There are 2 passages in this section. Each passage 292is followed by some questions or unfinished statements. For each of them 293there are four choices marked A), B), C) and D). You should decide on 294the best choice and mark the corresponding letter on Answer Sheet 2 with 295a single line through the centre.296Passage One297Questions 46 and 50 are based on the following passage.298That people often experience trouble sleeping in a different bed 299in unfamiliar surroundings is a phenomenon known as the “first-night” 300effect. If a person stays in the same room the following night they tend 301to sleep more soundly. Yuka Sasaki and her colleagues at Brown University 302set out to investigate the origins of this effect.30312 精品.资料Dr. Sasaki knew the first-night effect probably has something 304to do with how humans evolved. The puzzle was what benefit would be gained 305from it when performance might be affected the following day. She also 306knew from previous work conducted on birds and dolphins that these animals 307put half of their brains to sleep at a time so that they can rest while 308remaining alert enough to avoid predators (捕食者). This led her to wonder 309if people might be doing the same thing. To take a closer look, her team 310studied 35 healthy people as they slept in the unfamiliar environment 311of the university’s Department of Psychological Sciences. The312participants each slept in the department for two nights and were313carefully monitored with techniques that looked at the activity of their 314brains. Dr. Sasaki found, as expected, the participants slept less well 315on their first night than they did on their second, taking more than twice 316as long to fall asleep and sleeping less overall. During deep sleep, the 317participants’ brains behaved in a similar manner seen in birds and 318dolphins. On the first night only, the left hemispheres (半球) of their 319brains did not sleep nearly as deeply as their right hemispheres did. 320Curious if the left hemispheres were indeed remaining awake to 321process information detected in the surrounding environment, Dr. Sasaki 322re-ran the experiment while presenting the sleeping participants with 323a mix of regularly timed beeps (蜂鸣声) of the same tone and irregular 324beeps of a different tone during the night. She worked out that, if the 325left hemisphere was staying alert to keep guard in a strange environment, 326then it would react to the irregular beeps by stirring people from sleep 327and would ignore the regularly timed ones. This is precisely what she 328found.32946. What did researchers find puzzling about the first-night 330effect?331A) To what extent it can trouble people. C) What circumstances 332may trigger it.33313 精品.资料B) What role it has played in evolution. D) In what way it can 334be beneficial.33547. What do we learn about Dr. Yuka Sasaki doing her research? 336A) She found birds and dolphins remain alert while asleep.337B) She found birds and dolphins sleep in much the same way. 338C) She got some idea from previous studies on birds and dolphins 339D) She conducted studies on birds’ and dolphins’ sleeping 340patterns.34148. What did Dr. Sasaki do when she first did her experiment? 342A) She monitored the brain activity of participants sleeping in 343a new environment.344B) She recruited 35 participants from her Department of345Psychological Sciences.346C) She studied the differences between the two sides of347participants’ brains.348D) She tested her findings about birds and dolphins on human 349subjects.35049. What did Dr. Sasaki do when re-running her experiment?351A) She analyzed the negative effect of irregular tones on brains. 352B) She recorded participants’ adaptation to changed353environment.354C) She exposed her participants to two different stimuli.355D) She compared the responses of different participants.35614 精品.资料50. What did Dr. Sasaki find about the participants in her357experiment?358A) They tended to enjoy certain tones more than others.359B) They tended to perceive irregular beeps as a threat.360C) They felt sleepy when exposed to regular beeps.361D) They differed in their tolerance of irregular tones.362Passage Two363Questions 51 to 55 are based on the following passage.364It’s time to reevaluate how women handle confl ict at work. Being 365overworked or over-committed at home and on the job will not get you where 366you want to be in life. It will only slow you down and hinder your career 367goals.368Did you know women are more likely than men to feel exhausted? 369Nearly twice as many women than men ages 18-44 reported feeling “very 370tired” or “exhausted”, according to a recent study.371This may not be surprising given that this is the age range when 372women have children. It's also the age range when many women are trying 373to balance careers and home. One reason women may feel exhausted is that 374they have a hard time saying "no." Women want to be able todo it all 375volunteer for school parties or cook delicious meals-and so their answer 376to any request is often “Yes, I can.”377Women strugg le to say “no” in the workplace for similar reasons, 378including the desire to be liked by their colleagues. Unfortunately, this 379inability to say "no" may be hurting women's heath as well as their career. 380At the workplace, men use conflict as a way to position themselves, 381while women often avoid conflict or strive to be the peacemaker, because 38215 精品.资料they don't want to be viewed as aggressive or disruptive at work. For 383example, there’s a problem that needs to be addressed immediately, 384resulting in a dispute over should be the one to fix it. Men are more 385likely to face that dispute from the perspective of what benefits them 386most, whereas women may approach the same dispute from the perspective 387of what's the easiest and quickest way to resolve the problem-even388if that means doing the boring work themselves.389This difference in handling conflict could be the deciding factor 390on who gets promoted to a leadership position and who does not. Leaders 391have to be able to delegate and manage resources wisely –including staff 392expertise. Shouldering more of the workload may not earn you that393promotion. Instead, it may highlight your inability to delegate394effectively.39551. What does the author say is the problem with women?396A) They are often unclear about the career goals to reach.397B) They are usually more committed at home than on the job. 398C) They tend to be over-optimistic about how far they could go. 399D) They tend to push themselves beyond the limits of their 400ability.40152. Why do working women of child-bearing age tend to feel drained 402of energy?403A) They struggle to satisfy the demands of both work and home. 404B) They are too devoted to work and unable to relax as a result. 405C) They do their best to cooperate with their workmates.406D) They are obliged to take up too many responsibilities.40716 精品.资料53. What may hinder the future prospects of career women?408A) Their unwillingness to say “no”.409B) Their desire to be considered powerful.410C) An underestimate of their own ability.411D) A lack of courage to face challenges.41254. Men and woman differ in their approach to resolving workplace 413conflicts in that______.414A) women tend to be easily satisfied415B) men are generally more persuasive416C) men tend to put their personal interests first417D) women are much more ready to compromise41855. What is important to a good leader?419A) A dominant personality. C) The courage to admit failure420B) The ability to delegate.

You are required to select one word for each blank f rom a list of choices given in a word bank following the passage. Read the passage through carefully before makingyour choices. Each choice in the bank is identified by a letter: Please mark the corresponding letter for eachitem on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bankmore than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some26 skills that could help the treatment of human diseases.Pigeons are often seen as dirty birds and an urban 27 , but they are just the latest in a long line of animals that have been found to have abilities to help humans. Despite having as brain no bigger than the 28 of your index finger, pigeons have a very impressive 29 memory. Recently it was shown that they could be trained to be as accurate as humans at detecting breast cancer in images.Rats are often 30 with spreading disease rather than 31 it, but this long-tailed画mal is highly 32 —. Inside a rat's nose are up to 1 ,000 different types of olfactoryreceptors (嗅觉感受器），whereas humans only have 100 to 200 types. This gives rats the ability to detect 33 smells. As a result, some rats are being put to work to detect TB (肺结核）. When the rats detect the smell, they stop and rub their legs to 34 a sample is infected.Traditionally, a hundred samples would take lab technicians more than two days to 35 , but for a rat it takes less than 20 minutes. This rat detection method doesn't rely on specialist equipment. It is also more accurate—the rats are able to find more TB infections and, therefore, save more lives.Section B A)associatedD)nuisanceG)prohibitingJ)speci fyM)tipB)examineE)peakH)sensitiveK)superiorN)treatedC)indicateF)preventingI)slightL)suspiciousO)visualDirections: In this section, you are going to read a passage with ten statements attached to it.

Answer the questions bymarking the corresponding letter on Answer Sheet 2.Do In-Class Exams Make Students Study Harder?Research suggests they may study more broadly for the unexpected rather than search for answers.A)I have always been a poor test-taker. So it may seem rather strange that I have returned to college to finish thedegree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students who quickly supply the verbal answer while I am still processing the question.B)Since there is no way for me to avoid exams ,I am currently questioning what kind are the most taxing and ultimately beneficial. I have already sweated through numerous in-class midterms and finals, and now I have a professor who issues take-home ones. I was excited when I learned this, figuring I had a full week to do the research, read the texts, and write it all up. In fact, I was still rewriting my midterm the morning it was due. Tosay I had lost the thread is putting it mildly.C)As I was suffering through my week of anxiety, overthinking the material and guessing my grasp of it, I didsome of my own polling among students and professors. David Eisenbach, who teaches a popular class on U.S.presidents at Columbia, prefers the in-class variety. He believes students ultimately learn more and encourages them to form study groups. "That way they socialize over history outside the class, which wouldn't happen without the pressure of an in-class exam," he explained. "Furthermore, in-class exams force students to learn how to perform under pressure , an essential work skill. "D)He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard werecaught up in a scandal when it was discovered they had cheated on a take-home exam for a class entitled "Introduction To Congress. "Some colleges have what they call an "honor code," though if you are smart enough to get into these schools, you are either smart enough to get around any codes or hopefully, too ethical to consider doing so. As I sat blocked and clueless for two solid days, I momentarily wondered if I couldn't just call an expert on the subject matter which I was tackling, or someone who took the class previously, to get me go m g.E)Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appealto her school's professors to refrain from take-home exams. "Students risk health and well being, as well as performance in other end-of-term work, when faculty offers take-home exams without clear, time-limited boundaries," she told me. "Research now shows that regular quizzes, short essays, and other assignments over the course of a term better enhance learning and retention. "F)Most college professors agree the kind of exam they choose largely depends on the subject. A quantitative-basedone, for example, is unlikely to be sent home, where one could ask their older brothers and sisters to help.Vocational-type classes, such as computer science or journalism, on the other hand, are often more research­oriented and lend themselves to take-home testing. Chris Koch, who teaches "History of Broadcast Journalism"at Montgomery Community College in Rockville, Maryland, points out that reporting is about investigation rather than the memorization of minute details. "In my field, it's not what you know—it's what you know how to find out, "says Koch. "There is way too much information, and more coming all the time, for anyone to remember.I want my students to search out the answers to questions by using all the resources available to them. "G)Students'test-form preferences vary, too, often depending on the subject and course difficulty. "I prefer take­home essays because it is then really about the writing, so you have time to edit and do more research, "says Elizabeth Dresser, a junior at Barnard. Then there is the stress factor. Francesca Haass, a senior at Middlebury, says, "I find the in-class ones are more stressful in the short term, but there is immediate relief as you swallow information like mad, and then you get to forget it all. Take-homes require thoughtful engagement which can lead to longer term stress as there is never a moment when the time is up. "Meanwhile, Olivia Rubin, a sophomore at Emory, says she hardly even considers take-homes true exams. "If you understand the material and have the ability to articulate (说出）your thoughts, they should be a breeze. "H)How students ultimately handle tests may depend on their personal test-taking abilities. There are people whoalways wait until the last minute, and make it much harder than it needs to be. And then there are those who, not knowing what questions are coming at them , and having no resources to refer to , can freeze. And then there are we rare folks who fit both those descriptions.I)Yes , my advanced age must factor into the equation (等式），in part because of my inability to access the information as quickly. As another returning student at Columbia, Kate Marber, told me, "We are learning not only all this information, but essentially how to learn again. Our fellow students have just come out of high school. A lot has changed since we were last in school. "J)If nothing else, the situation has given my college son and me something to share. When I asked his opinion on this matter, he responded, "I like in-class exams because the time is already reserved, as opposed to using my free time at home to work on a test, " he responded. It seems to me that a compromise would be receiving the exam questions a day or two in advance, and then doing the actual test in class with the ticking clock overhead. K)Better yet, how about what one Hunter College professor reportedly did recently for her final exam: She encouraged the class not to stress or even study, promising that, "It is going to be a piece of cake. " When the students came in, sharpened pencils in hand, there was not a blue book in sight. Rather, they saw a large chocolate cake and they each were given a slice.36.Elderly students find it hard to keep up with the rapid changes in education.37.Some believe take-home exams may affect students'performance in other courses.38.Certain professors believe in-class exams are ultimately more helpful to students.39.In-class exams are believed to discourage cheating in exams.40.The author was happy to learn she could do some exams at home.41.Students who put off their work until the last moment often find the exams more difficult than they actually are.42.Different students may prefer different types of exams.43.Most professors agree whether to give an in-class or a take-home exam depends on the type of course beingtaught.44.The author dropped out of college some forty years ago.45.Some students think take-home exams will eat up their free time.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A) ,B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.That people often experience trouble sleeping in a different bed in unfamiliar surroundings is a phenomenon known as the "fast-night" effect. If a person stays in the same room the following night they tend to sleep more soundly. Yuka Sasaki and her colleagues at Brown University set out to investigate the origins of this effect.Dr. Sasaki knew the first-night effect probably has something to do with how humans evolved. The puzzle was what benefit would be gained from it when performance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these画mals put half of their brains to sleep at a time so that they can rest while remaining alert enough to avoid predators (捕食者）. This led her to wonder if people might be doing the same thing. To take a closer look, her team studied 35 healthy people as they slept in the unfamiliar envirorunent of the university's Department of Psychological Sciences. The participants each slept in the department for two nights and were carefully monitored with techniques that looked at the activity of their brains. Dr. Sasaki found ,as expected ,the participants slept less well on their first night than they did on their second ,taking more than twice as long to fall asleep and sleeping less overall. During deep sleep, the participants'brains behaved in a similar manner seen in birds and dolphins. On the first night only, the left hemispheres (半球）of their brains did not sleep nearly as deeply as their right hemispheres did.Curious if the left hemispheres were indeed remaining awake to process information detected in the surrounding envirorunent, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularlytimed beeps (峰鸣声）of the same tone and irregular beeps of a different tone during the night. She worked out that , if the left hemisphere was staying alert to keep guard in a strange environment, then it would react to the irregular beeps by stirring people from sleep and would ignore the regularly timed ones. This is precisely what she found.46. W hat did researchers find puzzling about the first-night effect?A) To what extent it can trouble people.B) What role it has played in evolution.C) What circumstances may trigger it.D) In what way it can be beneficial.47. W hat do we learn about Dr. Yuka Sasaki doing her research?A)She found birds and dolphins remain alert while asleep.B)She found birds and dolphins sleep in much the same way.C)She got some idea from previous studies on birds and dolphins.D)She conducted studies on birds'and dolphins'sleeping patterns.48. W hat did Dr. Sasaki do when she first did her experiment?A)She monitored the brain activity of participants sleeping in a new envirorunent.B)She recruited 35 participants from her Department of Psychological Sciences.C)She studied the differences between the two sides of participants'brains.D)She tested her findings about birds and dolphins on human subjects.49. W hat did Dr. Sasaki do when re-running her experiment?A)She analyzed the negative effect of irregular tones on brains.B)She recorded participants'adaptation to changed environment.C)She exposed her participants to two different stimuli.D)She compared the responses of different participants.50. W hat did Dr. Sasaki find about the participants in her experiment?A)They tended to enjoy certain tones more than others.B) They tended to perceive irregular beeps as a threat.C) They felt sleepy when exposed to regular beeps.D)They differed in their tolerance of irregular tones.Passage TwoQuestions 51 to 55 are based on the following passage.It's time to reevaluate how women handle conflict at work. Being overworked or over-committed at home and on the job will not get you where you want to be in life. It will only slow you down and hinder your career goals.Did you know women are more likely than men to feel exhausted? Nearly twice as many women than men ages 18-44 reported feeling "very tired" or "exhausted", according to a recent study.This may not be surprising given that this is the age range when women have children. It's also the age range when many women are trying to balance careers and home. One reason women may feel exhausted is that they have a hard time saying "no." Women want to be able to do it all—volunteer for school parties or cook delicious meals— and so their answer to any request is often "Yes, I can. "Women struggle to say " n o" in the workplace for similar reasons ,including the desire to be liked by their colleagues. Unfortunately, this inability to say "no" may be hurting women's health as well as their career.At the workplace, men use conflict as a way to position themselves, while women often avoid conflict or strive to be the peacemaker, because they don't want to be viewed as aggressive or disruptive at work. For example,there's a problem that needs to be addressed immediately, resulting in a dispute over who should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefits them most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem—even if that means doing the boring work themselves.This difference in handling conflict could be the deciding factor on who gets promoted to a leadership position and who does not. Leaders have to be able to delegate and manage resources wisely—including staff expertise. Shouldering more of the workload may not earn you that promotion. Instead, it may highlight your inability to delegate effectively.51.What does the author say is the problem with women?A)They are often unclear about the career goals to reach.B) They are usually more committed at home than on the job.C) They tend to be over-optimistic about how far they could go.D) They tend to push themselves beyond the limits of their ability.52. Why do working women of child-bearing age tend to feel drained of energy?A)They struggle to satisfy the demands of both work and home.B)They are too devoted to work and unable to relax as a result.C) They do their best to cooperate with their workmates.D)They are obliged to take up too many responsibilities.53.What may hinder the future prospects of career women?A)Their unwillingness to say "no".B)Their desire to be considered powerful.C) An underestimate of their own ability.D)A lack of courage to face challenges.54. Men and women differ in their approach to resolving workplace conflicts in that.A) women tend to be easily satisfiedB) men are generally more persuasiveC) men tend to put their personal interests firstD) Women are much more ready to compromise55.What is important to a good leader?A) A dominant personality. B) The ability to delegate.C) The courage to admit failure.D) A strong sense of responsibility.Part IV Translation (30 minutes)Directions : 的r this part, you are allowed 30 minutes to translate a passage from Chinese into English.

During this decade new forms of entertainment, commerce, research, and communication became commonplacein the U. S. The driving force behind much of this change was a (n) 26 popularly known as the Internet.The Internet was developed during the 1970s by the Department of Defense. In the case of an attack, military advisers suggested the 27 of being able to operate one computer from another terminal. In the early days, the Internet was used mainly by scientists to communicate with other scientists. The Internet 28 under government control until 1984.One early problem faced by Internet users was speed. Phone lines could only transmit information at a 29 rate. The development of fiber-optic （光纤）cables allowed for billionsof bits of information to be received every minute. Companies like Intel developed faster microprocessors, so personal computers could processthe 30 signals at a more rapid rate.In the early 1990s, the World Wide Web was developed, in large part, for 31 purposes. Corporations created home pages where they could place text and graphics to sell products. Soon airline tickets, hotel32 , and even cars and homes could be purchased online.

Then decades passed without my touching a knitting needle. But within two Mondays in the group, I was hooked, not only on knitting but also on crocheting ( 钩织), and I was on my way tobecoming a highly productive crafter.C) I 've made countless baby blankets, sweaters, scarves, hats, caps for newborns. I take a knitting project with me everywhere, especially when I have to sit still and listen. As I discovered in college, when my hands are busy, my mind stays focused on the here and now.D) It seems, too, that I 'm part of a national renewal of interest in needle and other handicrafts ( 手工艺).The Craft Yam Council reports that a third of women ages 25-35 now knit or crochet. Even men and schoolchildren are swelling the ranks, among them my Mend's three small grandsons. Last April, the council created a Stitch Away Stress ” campaign in honor of National Stress Awareness Month. Dr. Herbert Benson, a pioneer in mind/body medicine and author of The Relaxation Response, says that the repetitive action of needlework can induce arelaxed state like that associated with meditation ( yoga. Once you get沉思) and beyond the initial learning curve, knitting and crocheting canlower heart rate and blood pressure.E） But unlike meditation, craft activities result in tangible and often useful products that can enhance self-esteem. I keep photos of my singular accomplishments on my cellphone to boost my spirits when needed.F）Since the 1990s, the council has surveyed hundreds of thousands of knitters and crocheters, whoroutinely list stress relief and creative fulfillment as the activities ' main benefits. Among them is the father of a prematurely born daughter who reported that during the baby's five weeks in the intensive care unit,“learni ng how to knit infant hats gaveme a sense of purpose during a time that I felt very helpless. It 's a hobby that I 've stuck with, and it continues to help mecope with stress at work, provide a sense of order in hectic （忙乱的） days, and allow my brain time t o solve problems. ”G） A recent email from the yam （纺纱） company Red Hearttitled “Health Benefits of Crocheting and Knitting ” prompted me to explore what else might be known about the health value of activities like knitting. My research revealed that therewards go well beyond replacing stress and anxiety with the satisfaction of creation.H）For example, Karen Hayes, a life coach in Toronto, conducts knitting therapy programs, including Knit to Quit to help smokers give up the habit, and Knit to Heal for people coping with health crises, like a cancer diagnosis or serious illness of a family member. Schools and prisons with craft programs report that they have a calming effect and enhance social skills. And having to follow instructions on complex craft pr ojects can improve children 's math skills.I）Somepeople find that craftwork helps them control their weight. Just as it 's challenging to smokewhile knitting, when hands are holding needles and hooks, there 's less snacking and mindless eating out of boredom.J） I ' ve found that my handiwork with yam has helped my arthritic （患关节炎的）fingers remain more dexterous （灵巧的） as I age. A woman encouraged to try knitting and crocheting after developing an autoimmune disease that caused a lot of hand pain reported on the Craft YamCouncil site that her hands are now less stiff and painful.K） A 2009 University of British Columbia study of 38 women with aneating disorder who were taught to knit found that learning the craft led to significant improvements. Seventy-four percent of the women said the activity lessened their fears and kept them from thinking about their problem.L） Betsan Corkhill, a wellness coach in Bath, England, and author of the book Knit for Health & Wellness, established a website, Stitchlinks, to explore the value of what she calls therapeutic knitting. Among her respondents, 54 percent of those who were clinically depressed said that knitting made them feel happy or very happy. In a study of 60 self-selected people with persistent pain, Ms. Corkhill and colleagues reported that knitting enabled them to redirect their focus, reducing their awareness of pain. She suggested that the brain can process just so much at once, and that activities like knitting and crocheting makeit harder for the brain to register pain signals. Perhaps most exciting is research that suggests that crafts like knitting and crocheting may help to keep off a decline in brain function with age. In a 2011 study, researchers led by Dr. Yonas Geda at the Mayo Clinic in Rochester interviewed a random （随机的） sample of 1,321 people ages 70-89, most of whomwere cognitively （在认知方面） normal,about the cognitive activities they engaged in late in life. The study, published in the Journal of Neuropsychiatry & Clinical Neurosciences, found that those who engaged in crafts like knitting and crocheting had adiminished chance of developing mild cognitive disorder and memory loss.M) Although it is possible that only people who are cognitively healthy would pursue such activities, those who read newspapers or magazines or played music did not show similar benefits. The researchers speculate that craft activities promote the development of nerve pathways in the brain that help to maintain cognitive health.N) In support of that suggestion, a 2014 study by Denise C. Park of the University of Texas at Dallas and colleagues demonstrated that learning to knit or do digital photography enhanced memoryfunction in older adults. Those who engaged in activities that were not intellectually challenging, either in a social group or alone, did not show such improvements.O) Given that sustained social contacts have been shown to support health and a long life, those wishing to maximize the health value of crafts might consider joining a group of like-minded folks.I for one try not to miss a single weekly meeting of my knitting group.36. When the author was a college student, she found that knitting helped her concentrate.37. Knitting can help people stay away from tobacco.38. Even men and children are now joining the army of knitters.39. Being a memberof a crafts group enhances one's health and prolongs one 's life.40. Knitting diverts people 's attention from their pain.41. The author learnt to knit as a teenager, but it was not until she was much older that she became keenly interested.42. Whenpeople are knitting, they tend to eat fewer snacks.43. Survey findings show that knitting can help people relieve stress.44. According to a study, knitters and crocheters are less likely to suffer mild cognitive damage.45. The products of knitting can increase one 's sense of self-respect.Section CDirections: There are 2 passages in this section. Each passage is followed by somequestions or unfinished statements.

Yet cities in sub-Saharan Africa are not getting richer the way cities in the rest of the world have. Most urban Africans live in slums ( 贫民窟); migrants are often not much better off than they were in the countryside. Why?The immediate problem is poverty. Most of Africa is urbanising at a lower level of income than other regions of the world did. That means there 's little money around forinvestment that would makecities liveable and more productive. Without upgrades and new capacity, bridges, roads and power systems are unable to cope with expanding populations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense and unpredictability, things that keep investors away.In other parts of the world, increasing agricultural productivity and industrialization went together. More productive farmers meant there was a surplus that could feed cities; in turn, that created a pool of labour forfactories. But African cities are different. They are too often built around consuming natural resources. Government is concentrated in capitals, so is the money. Most urban Africans work for a small minority of the rich, who tend to be involved in either cronyish （有裙带关系的）businesses or politics. Since African agriculture is still broadly unproductive, food is imported, consuming a portion of revenue.So what can be done? Though African countries are poor, not all African cities are. In Lagos, foreign oil workers can pay as much as $65,000 per year in rent for a modest apartment in a safe part of town. If that income were better taxed, it might provide the revenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city 's population grows by 5% a year, it is difficult to keep up.46. What do we learn from the passage about cities in sub-Saharan Africa?A) They have more slums than other cities in the world.B) They are growing fast without becoming richer.C) They are as modernised as many cities elsewhere.D) They attract migrants who want to be better off.47. What does the author imply about urbanisation in other parts of the world?A) It benefited from the contribution of immigrants.B) It started when people 's income was relatively high.C) It benefited from the accelerated rise in productivity.D) It started with the improvement of people 's livelihood.48. Why is sub-Saharan Africa unappealing to investors?A) It lacks adequate transport facilities.B) The living expenses there are too high.C) It is on the whole too densely populated.D) The local governments are corrupted.49. In what way does the author say African cities are different?A) They have attracted huge numbers of farm labourers.B) They still rely heavily on agricultural productivity.C) They have developed at the expense of nature.D) They depend far more on foreign investment.50. What might be a solution to the problems facing African cities?A) Lowering of apartment rent. C) More rational overall planning.B) Better education for residents. D) A more responsible government.Passage TwoQuestions 51 to 55 are based on the following passage.For the past several decades, it seems there 's been a general consensus on howto get ahead in America: Get a college education, find a reliable job, and buy your own home. But do Americans still believe in that path, and if they do, is it attainable?The most recent National Journal poll asked respondents about the American dream, what it takes to achieve their goals, and whether or not they felt a significant amount of control over their ability to be successful. Overwhelmingly, the results show that today, the idea of the American dream —and what it takes to achieve it —looks quite different than it did in the late 20th century.By and large, people felt that their actions and hard work—not outside forces —were the deciding factor in howtheir lives turned out. But respondents had decidedly mixed feelings about what actions make for a better life in the current economy.In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority —52 percent —think that young people do not need a four-year college education in order to be successful.Miguel Maeda, 42, who has a master 's degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability his parents and grandparents never did.While some, like Maeda, emphasized the value of the degree rather than the education itself, others still see college as a way to gain new perspectives and life experiences.Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, thinks “personal drive ” is far more important than just going to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook, are the necessary ingredients for a successful life in America.51. It used to be commonly acknowledged that to succeed in America, one had to have ____ .A) an advanced academic degree C) a firm belief in their dreamB) an ambition to get ahead D) a sense of drive andpurpose52. What is the finding of the latest National Journal poll concerning the American dream?A) More and more Americans are finding it hard to realize.B) It remains alive amongthe majority of American people.C) Americans ' idea of it has changed over the past few decades.D) An increasing number of young Americans are abandoning it.53. What do Americans now think of the role of college education in achieving success?A) It still remains open to debate.B) It has proved to be beyond doubt.C) It is no longer as important as it used to be.D) It is much better understood now than ever.54. How do some people view college education these days?A) It promotes gender equality. C) It adds to cultural diversity.B) It needs to be strengthened. D) It helps broaden their minds.55. What is one factor essential to success in America, according to Will Fendley?A) A desire to learn and to adapt. C) A willingness to commit oneself.B) A strong sense of responsibility. D) A clear aim and high motivation.Part IV Translation (30 minutes)Directions: For this part, you are allowed SO minutes to translate a passage from Chinese into English.

2017年12月大学英语四级真题及答案解析(全三套) 四级听力第一套：News Report 1A 9-year-old girl in New Mexico has raised more than $500 for her little brother who needs heart surgery in Houston, Texas this July. Addison Witulski's grandmother Kim Allred, said Addison probably overheard a conversation between family members talking about the funds needed to get her little brother to treatment. "I guess she overheard her grandfather and me talking about how we're worried about how we're going to get to Houston, for my grandson's heart surgery," said Allred. She decided to go outside and have a lemonade stand and make some drawings and pictures and sell them.” That's when Addison and her friends Erika and Emily Borden decided to sell lemonade for 50 cents a cup and sell pictures for 25 cents each.Before Allred knew it, New Mexico State Police Officers were among the many stopping by helping them reach a total of $568. The family turned to social media expressing their gratitude saying, "From the bottom of our hearts, we would like to deeply thank each and every person that stopped by!"1: Who did Addison raise the money for?2: How did Addison raise the money?1.D) Her little brother.2.B) By selling lemonade and pictures.News Report 2:Last week, France announced that the country will pave 621 miles of road with solar panels over the next five years with the goal of providing cheap, renewable energy to five million people. Called the Ward Way, the roads will be built through joint efforts with the French road building company Colas and the National Institute of Solar Energy. The companyspent the last five years developing solar panels that are only about a quarter of inch thick and are strong enough to stand up to heavy highway traffic without breaking or making the roads more slippery. The panels are also designed so that they can be installed directly on top of the existing roadways, making them relatively cheap and easy to install. France is the first country to kick around the idea of paving its roads with solar panels. In November 2015, the Netherlands completed a 229-foot long bike path paved with solar panels as a test for future projects. However, this is the first time a panel has been designed to be laid directly on top existing roads and the first project to install the panels on public highways.3: What was France’s purpose of constructing the Ward Way?4: What is special about the solar panels used in the Ward Way?3.B) Providing clean energy to five million people.4.C) They can be laid right on top of existing highways.News Report 3Lions have disappeared from much of Africa, but for the past few years scientists have wondered if the big cats were hanging on in remote parts of Sudan and Ethiopia. Continuous fighting in the region has made surveys difficult. But scientists released a report Monday documenting with hard evidence the discovery of "lost lions." A team with Oxford University’s Wildlife Conservation Research Unit, supported by a charity organization, spent two nights in November camping in a national park in northwest Ethiopia on the Ethiopia-Sudan border. The researchers set out six camera traps, capturing images of lions, and the identified lion tracks. The scientists concluded that lions are also likely to live in a neighboring national park across the border in Sudan. The International Union for Conservation of Nature had previously considered the area a "possible range" for the species, and local people had reported seeing lions in the area, but no one presented convincing evidence.5: What has made it difficult to survey lions in remote parts of Sudan and Ethiopia?6: What was the main purpose of the research?7: What did the researchers find in the national park?5.C)Endless fighing in the region.6.D)To find evidence of the lions'disappearance.7.A)Lions'tracks.Conversation OneM: I beg you’re looking forward to the end of this month. Aren’t you?W: Yes, I am. How did you know?M: David told me you had a special birthday coming up.W: Oh, yes. That’s right. This year would be my golden birthday.M: What does that mean? I’ve never heard of a golden birthday.W: I’ve actually just learned of this concept myself. Fortunately, just in time to celebrate. A golden or lucky birthday is when one turns the age of their birth date. So, for example, my sister’s birthday is December 9th and her golden birthday would have been the year she turns 9 years old. Come to think of it , my parents did throw her a surprise party that year. M: Intere sting. Too bad I missed mine. My golden birthday would’ve been four years ago.I assumedly got a big plan then.W: Actually yes. My husband is planning a surprise holiday for the two of us next week. I have no idea what he’s gotten in mind, but I’m excited to find out. Has he mentioned anything to you?M: He might have.W: Anything you’d like to share? I’m dying to know what kind of trip he has planned where we’re going.M: Yeah, nothing at all.W: Not a clue. Hard to imagine, isn’t it! Though I must say, I think it has been even more fun keeping the secret for me the past few weeks.M: I’m sure both of you will have a fantastic time. Happy golden birthday! I can’t wait to hear all about it when you get back.8. What does the woman looking forward to?9. W hat did the woman’s parents do on her sister’s lucky birthday?10. What is the woman eager to find out about?11. What does the man say at the end of the conversation?8.D) Her "lucky brithday".9.A) Threw her a superise party.10.C) The trip her husband has planned.11.B) He is eager to learn how the couple's holiday turns out.Conversation TwoW: Mr. Green, What do you think makes a successful negotiator?M: Well, It does hard to define, but I think successful negotiators have several things in common. They are always polite and rational people, they are firm, but flexible. They can recognize power and know how to use it. They are sensitive to the dynamics in the negotiation, the way it raises and falls, and how may change the direction. They project the image of confidence, and perhaps most importantly, they know when to stop.W: And what about an unsuccessful negotiator?M: Well, this probably all of us when we start out. We are probably immature and over-trusting, too emotional or aggressive. We are unsure of ourselves and want to be liked by everyone. Good negotiators learn fast, pool negotiators remain like that and go on losing negotiations,W: In your opinion, can the skills of negotiation be taught?M: Well, you can teach someone how to prepare for negotiation. There perhaps six stages in every negotiation, get to know the other side, stay your goals, start the process, clarify there is a disagreement or conflict, reassess your position, making acceptable compromise, and finally reach some agreements and principals. These stages can be studied, and strategies to be used in each can be planned before-hand. But I think the really successfulnegotiator is probably born with the sixth sense that may respond properly to the situation at hand.W: The artistic sense you just described?M: Yes, that’s right12. What’s the man say about good negotiators?13. What does the man say, maybe the most important thing to a successful negotiator?14. How is a good negotiator different from a poor one?15. What’s th e first stage of a negation according to the man?12. A) They are sensitive to the dynamics of a negotiation.13. B) They know when to stop.14. C) They learn quickly.15. D) Get to know the other side.Passage OneSome people wonder why countries spend millions of dollars on space projects. They want to know how space research helps people on earth. Actually, space technology helps people on earth every day. This is called spin-off technology. Spin-off technology is space technology that is now used on earth. In early space programs, such as the Apollo missions of the 1960s and 1970s and in the space shuttle missions today, scientists developed objects for the astronauts to use on the moon and in space. We now use some of these objects every day. For example, we have quartz crystal clocks and watches accurate to within one minute a year. We purify the water we drink with the water filter designed for the astronauts to use in space. The cordless hand held tools we use in our homes, such as vacuum cleaners, flashlights, drills came from the technology of these early space programs. On cold winter days, we can stay warm with battery-operated gloves and socks, especially made coats and jackets. All the clothes are similar to the space suits designs that kept astronauts comfortable in the temperatures of the moon, in our spin offs from space technology. These products are only a few examples of the many ways spacetechnology helps us in our everyday lives. No one knows how new spin off technology from the international space station will help us in the future.16. What do some people want to know about space exploration?17. What did scientist do for the space shuttle missions?18. What does the speaker say about the quartz crystal clocks and watches?16. D) How space research benefits people on Earth.17. B) They developed objects for astronauts to use in outer space.18. C) They are extremely accurate.Passage TwoWell, if I could get back in history and live, I'd like to get back to the 18th century and perhaps in colonial America in Yankee new England where one of my ancestors lived, because it was the beginning of something. By the 18th century, there was a feeling of community that had grown. My ancestor was the preacher traveling around countryside. People lived in small communities. It was fisherman and farmers who provided fresh food that tasted and looked like food. Unlike today’s supermarkets, and there were small towns and New York wasn't that far away. I'm deeply attached to the puritan tradition not in a religious sense. But they believed in working for something, working for goals. And I like that. They worked hard at whatever they did, but they had a sense of achievement. They believed in goodness, in community, and helping one another. I love the colonial fabrics or the silver works, the furnishings, the combination of elegance simplicity. I'd love it. The printing, the books, I’m very attached to all that kind of thing. That may not all be very entertaining in the modern sense of the world, but I would have enjoyed spending my evenings in that environment, discussing new ideas, building a new world, and I can see myself sitting on a small chair by the fire doing needle work.19. Why does the speaker say she would like to go back and live in the 18th century America?20. What does the speaker say about the Puritans?21. What would the speaker like doing if she could go back to the past?19. C)It marked the beginning of something new.20. A)They believed working for goals.21. D)Doing needlework by the fire.Passage threeIf you are lost in the woods, a little knowledge concerned with some people called a hardship into an enjoyable stay away from the troubles of modern society. When you think you're lost,sit down on the log or rock, or lean against the tree, and recite something you are memorized to bring your mind to the point where is under control. Don’t run blindly if you must move, don't follow stream unless you know it, and in that case you're not lost. Streams normally flow through wide land before they reach a lake or river though there are more eatable plants, there may also be wild animals, poisonous snakes, and other hazards. Many experts feel it is the wisest to walk up hill. At the top of most hills and mountains are trails living back to civilizations. If there are no trails, you're much easier to be seen on top of the hill. And you may even spot the highway or railroad from this point. Nowadays, the first way some of you search for you is by air. In the wide lands or in dense grass, we're very hard to spot. Anytime you are going to the woods, somebody should know where you're going, and when you are expected to return, also when someone comes to looking, you should be able to signal to them.22. What does the speaker advise you to do first if you are lost in the woods?23. What will happen if you follow an unknown stream in the woods?24. What do many experts think is the wisest thing to do if you're lost in the woods?25. What should you do before you go into the woods?22. C) Sit down and try to calm yourself23. B) You may expose yourself to unexpected dangers.24. D) Walk uphill.25.

One educator named Dori Roberts decided to do somethingto change this system. Dori taughthigh school engineering for 11 years. Shenoticed there was a real void in quality STEM education at all 27 ofthe public educational system. She said, “I started Engineering For Kids (EFK)after noticing a real lack of math, science and engineering programs to 28 myown kids in.”She decided to start an afterschool programwhere children 29 in STEM-based competitions. The clubgrew quickly and when it reached 180 members and the kids in the program wonseveral state 30 , she decided to devote all her time tocultivating and 31 it. The global business EFK was born.Dori began operating EFK out of her Virginiahome, which she then expanded to 32 recreation centers. Today, the EFK program 33 over 144 branches in 32 states within theUnited States and in 21 countries.

To be curious, we need to realize first of all thatthere are many things we don’t know.H）Moreover,in order to be curious , ” you have to aware of a gap in your knowledge in thefirst place.” Although Leslie perhaps paints a bit broadly in contending thatmost of usare unaware of how much we don’t know, he’s surely right to pointout that the problem is gro wing:”Google can give us the powerful illusion thatall questions have definite answers.”37. According to Leslie, curiosity is essential to one’ssuccess.D) Thejournalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Yo ur Future Depends on It,insists that the answer to that last question is “Yes”. Leslie argues thatcuriosity is a much-overlooked human virtue, crucial to our success, and thatwe are losing it.38. We should feel happy when we pursue knowledge forknowledg e’s sake.O) All of which brings us back to Goodelland the Christie case and Benghazi. Each critic in those examples is charging,in a different way, that someone in authority is intentionally being incurious.I leave it to the reader's political preference to decide which, if any,charges should stick. But let’s be careful about demanding curiosity about theother side’s weaknesses and remaining determinedly incurious about our own. Weshould be delighted to pursue knowledge for its own sake—even when what we findout is something we didn't particularly want to know.39. Political leaders’ lack of curiosity will result inbad consequences.M) AlthoughLeslie’s book isn’t about politics, he doesn’t entirely shy away from theproblem. Political leaders, like leaders of other organizations, should becurious. They should ask questions at crucial moments. There are seriousconsequences, he warns, in not wanting to know.40. There are often accusations about politicians’ andthe media’s l ack of curiosity to find out the truth.B) Theaccusation of incuriosity is one that we hear often, carrying the suggestionthat there is something wrong with not wanting to search out the truth. “I havebeen bothered for a long time about the curious lac k of curiosity,” said aDemocratic member of the New Jersey legislature back in July, referring to aninsufficiently inquiring attitude on the part of an assistant to New JerseyGovernor Chris Christie who chose not to ask hard questions about the GeorgeWashi ngton Bridge traffic scandal. “Isn’t the mainstream media the least bitcurious about what happened?” wrote conservative writer Jennifer Rubin earlierthis year, referring to the attack on Americans in Benghazi, Libya.41. The less curious a child is, the less knowledge thechild may turn out to have.L) Schooleducation, he warns, is often conducted in a way that makes children incurious.Children of educated and upper-middle-class parents turn out to be far morecurious, even at early ages, than children of working class and lower classfamilies. That lack of curiosity produces a relative lack of knowledge, and thelack of knowledge is difficult if not impossible to compensate for later on.42. It is widely accepted that academic accomplishmentlies in both intelligence and diligence.K) Citingthe work of psychologists and cognitive（认知的）scientists, Leslie criticizes the received wisdomthat academic success is the result of a combination of intellectual talent andhard work. Curiosity, he argues, is the third key factor—and a difficult one topreserve. If not cultivated, it will not survive：“Childhood curiosity is a collaboration between childand adult. The surest way to kill it is to leave it alone.”43. Visiting a bookshop as curiosity leads us can be agood way to entertain ourselves.J) Somewhatnostalgically（怀旧地），he quote John Maynard Keynes’s justlyfamous words of praise to the bookstore:”One should enter it vaguely, almost ina dream, and allowwhat is there freely to attract and influence the eye. Towalk the rounds of the bookshops, dipping in as curiosity dictates, should bean afternoon’s entertainment.” If only!44. Both the rise of the Internet and reduced appetitefor literary fiction contribute to people’s declining curiosity.G) Lesliepresents considerable evidence for the proposition that the society as a wholeis growing less curious. In the U.S. and Europe, for example, the rise of theInternet has led to a declining consumption of news from outside the reader’sborders. But not e verything is to be blamed on technology. The decline ininterest in literary fiction is also one of the causes identified by Leslie.Reading literary fiction, he says, make us more curious.45.Mankind wouldn’t be so innovative without curiosity.F) Why isthis a problem? Because without curiosity we will lose the spirit of innovationand entrepreneurship. We will see unimaginative governments and dyingcorporations make disastrous decisions. We will lose a vital part of what hasmade humanity as a whole so successful as a species.仔细阅读46.

You may not use any of the words in the bank more than once.Questions 26 to 35 are based on the following passage.Technological changes brought dramatic new options to Americans living in the 1990s. During this decade new forms of entertainment, commerce, research, and communication became commonplace in the U. S. The driving force behind much of this change was a (n) 26 popularly known as the Internet.The Internet was developed during the 1970s by the Department of Defense. In the case of an attack, military advisers suggested the27of being able to operate one computer from another terminal. In the early days, the Internet was used mainly by scientists to communicate with other scientists. The Internet28under government control until 1984.One early problem faced by Internet users was speed. Phone lines could only transmit information at a29rate. The development of fiber-optic ( 光纤 )cables allowed for billions of bits of information to be received every minute. Companies like Intel developed faster microprocessors, so personal computers could process the30signals at a more rapid rate.In the early 1990s, the World Wide Web was developed, in large part, for31purposes. Corporations created home pages where they could place text and graphics to sell products. Soon airline tickets, hotel32, and even cars and homes could be purchased online. Universities33research data on the Internet, so students could find34information without leaving their dormitories. Companies soon discovered that work could be done at home and35online, so a whole new class of telecommuters began to earn a living from home offices unshaven and wearing pajamas (睡衣 ).A) advantage I) maintainedB) commercial J) occupationsC) conservation K) postedD) equipped L) remainedE) incoming M) reservationsF) innovation N) submittedG) limited O) valuableH) localSection BDirections: In this section, you are going to read a passage with ten statements attached to it. Eachstatement contains information given in one of the paragraphs. Identify the paragraph from whichthe information is derived. You may choose a paragraph more than once. Each paragraph ismarked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The Health Benefits of KnittingA)About 15 years ago, I was invited to join a knitting group. I agreed to give it a try.B)My mother had taught me to knit at 15, and I knitted in class throughout college and for afew years thereafter. Then decades passed without my touching a knitting needle. But within twoMondays in the group, I was hooked, not only on knitting but also on crocheting ( 钩织 ), and I wason my way to becoming a highly productive crafter.C)I ’ vemade countless baby blankets, sweaters, scarves, hats, caps for newborns. I take aknitting project with me everywhere, especially when I have to sit still and listen. As I discoveredin college, when my hands are busy, my mind stays focused on the here and now.D) It seems, too, that I’ m part of a national renewal of interest in needle and other handicrafts(手工艺 ).The Craft Yam Council reports that a third of women ages 25-35 now knit or crochet.Even men and schoolchildren are swelling the ranks, among them my Mend’ s three small grandsons Last April, the council created a Stitch Away Stress”campaign in honor of National StressAwareness Month. Dr. Herbert Benson, a pioneer in mind/body medicine and author of TheRelaxation Response, says that the repetitive action of needlework can induce a relaxed state likethat associated with meditation ( 沉思 ) and yoga. Once you get beyond the initial learning curve,knitting and crocheting can lower heart rate and blood pressure.E)But unlike meditation, craft activities result in tangible and often useful products that canenhance self-esteem. I keep photos of my singular accomplishments on my cellphone to boostmy spirits when needed.F)Since the 1990s, the council has surveyed hundreds of thousands of knitters and crocheters,who routinely list stress relief and creative fulfillment as the activities’ main benefits. A is the father of a prematurely born daughter who reported that during the baby’ s five weeks intensive care unit,“ learning how to knit infant hats gave me a sense of purpose during a time thatI felt very helpless. It’ s a hobby that I’ ve stuck with, and it continues to help me cope with stress at work, provide a sense of order in hectic ( 忙乱的 ) days, and allow my brain time to solve problems.”G) A recent email from the yam ( 纺纱 ) company Red Heart titled“ HealthBenefits ofCrocheting and Knitting ” prompted me to explore what else might be known about the health value ofactivities like knitting. My research revealed that the rewards go well beyond replacing stress and anxietywith the satisfaction of creation.H)For example, Karen Hayes, a life coach in Toronto, conducts knitting therapy programs,including Knit to Quit to help smokers give up the habit, and Knit to Heal for people coping with healthcrises, like a cancer diagnosis or serious illness of a family member. Schools and prisons with craftprograms report that they have a calming effect and enhance social skills. And having to followinstructions on complex craft projects can improve children’ s math skills.I) Some people find that craftwork helps them control their weight. Just as it’ s challe smoke while knitting, when hands are holding needles and hooks, there’ s less snacking and mind eating out of boredom.J) I ’ ve found that my handiwork with yam has helped my arthritic患(关节炎的 )fingers remainmore dexterous ( 灵巧的) as I age. A woman encouraged to try knitting and crocheting afterdeveloping an autoimmune disease that caused a lot of hand pain reported on the Craft Yam Councilsite that her hands are now less stiff and painful.K) A 2009 University of British Columbia study of 38 women with an eating disorder whowere taught to knit found that learning the craft led to significant improvements. Seventy-fourpercent of the women said the activity lessened their fears and kept them from thinking about theirproblem.L)Betsan Corkhill, a wellness coach in Bath, England, and author of the book Knit for Health&Wellness, established a website, Stitchlinks, to explore the value of what she calls therapeuticknitting. Among her respondents, 54 percent of those who were clinically depressed said thatknitting made them feel happy or very happy. In a study of 60 self-selected people with persistentpain, Ms. Corkhill and colleagues reported that knitting enabled them to redirect their focus,reducing their awareness of pain. She suggested that the brain can process just so much at once, andthat activities like knitting and crocheting make it harder for the brain to register pain signals.Perhaps most exciting is research that suggests that crafts like knitting and crocheting may help tokeep off a decline in brain function with age. In a 2011 study, researchers led by Dr. Yonas Geda atthe Mayo Clinic in Rochester interviewed a random ( 随机的 ) sample of 1,321 people ages 70-89,most of whom were cognitively ( 在认知方面 ) normal, about the cognitive activities they engaged inlate in life. The study, published in the Journal of Neuropsychiatry & Clinical Neurosciences, foundthat those who engaged in crafts like knitting and crocheting had a diminished chance of developingmild cognitive disorder and memory loss.M)Although it is possible that only people who are cognitively healthy would pursue suchactivities, those who read newspapers or magazines or played music did not show similar benefits.The researchers speculate that craft activities promote the development of nerve pathways in thebrain that help to maintain cognitive health.N)In support of that suggestion, a 2014 study by Denise C. Park of the University of Texas atDallas and colleagues demonstrated that learning to knit or do digital photography enhancedmemory function in older adults. Those who engaged in activities that were not intellectuallychallenging, either in a social group or alone, did not show such improvements.O)Given that sustained social contacts have been shown to support health and a long life, thosewishing to maximize the health value of crafts might consider joining a group of like-minded folks.I for one try not to miss a single weekly meeting of my knitting group.36.When the author was a college student, she found that knitting helped her concentrate.37.Knitting can help people stay away from tobacco.38.Even men and children are now joining the army of knitters.39.Being a member of a crafts group enhances one’ s health and prolongs one’ s life.40.Knitting diverts people’ s attention from their pain.41.The author learnt to knit as a teenager, but it was not until she was much older that shebecame keenly interested.42.When people are knitting, they tend to eat fewer snacks.43.Survey findings show that knitting can help people relieve stress.44.According to a study, knitters and crocheters are less likely to suffer mild cognitive damage.45. The products of knitting can increase one’ s sense of self-respect.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions orunfinished statements. For each of them there are four choices marked A), B), C) and D). Youshould decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a singleline through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Nobody really knows how big Lagos is. What’ s indisputable is that it’ s growing very quick Between now and 2050, the urban population of Africa could triple. Yet cities in sub-SaharanAfrica are not getting richer the way cities in the rest of the world have. Most urban Africans live inslums (贫民窟 ); migrants are often not much better off than they were in the countryside. Why?The immediate problem is poverty. Most of Africa is urbanising at a lower level of income thanother regions of the world did. That means there ’ s little money around for investment that would make citiesliveable and more productive. Without upgrades and new capacity, bridges, roads andpower systems are unable to cope with expanding populations. With the exception of South Africa,the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leadsto expense and unpredictability, things that keep investors away.In other parts of the world, increasing agricultural productivity and industrialization wenttogether. More productive farmers meant there was a surplus that could feed cities; in turn, thatcreated a pool of labour for factories. But African cities are different. They are too often built aroundconsuming natural resources. Government is concentrated in capitals, so is the money. Most urbanAfricans work for a small minority of the rich, who tend to be involved in either cronyish (有裙带关系的 )businesses or politics. Since African agriculture is still broadly unproductive,food isimported, consuming a portion of revenue.So what can be done? Though African countries are poor, not all African cities are. In Lagos,foreign oil workers can pay as much as $65,000 per year in rent for a modest apartment in a safepart of town. If that income were better taxed, it might provide the revenue for better infrastructure.If city leaders were more accountable to their residents, they might favour projects designed to helpthem more. Yet even as new roads are built, new people arrive. When a city ’ s population grow 5% a year, it is difficult to keep up.46.What do we learn from the passage about cities in sub-Saharan Africa?A) They have more slums than other cities in the world.B) They are growing fast without becoming richer.C) They are as modernised as many cities elsewhere.D) They attract migrants who want to be better off.47.What does the author imply about urbanisation in other parts of the world?A) It benefited from the contribution of immigrants.B) It started when people’ s income was relatively high.C)It benefited from the accelerated rise in productivity.D) It started with the improvement of people’ s livelihood.48.Why is sub-Saharan Africa unappealing to investors?A) It lacks adequate transport facilities.B) The living expenses there are too high.C) It is on the whole too densely populated.D) The local governments are corrupted.49.In what way does the author say African cities are different?A) They have attracted huge numbers of farm labourers.B) They still rely heavily on agricultural productivity.C) They have developed at the expense of nature. D)They depend far more on foreign investment.50.What might be a solution to the problems facing African cities?A) Lowering of apartment rent.C) More rational overall planning.B) Better education for residents.D) A more responsible government.Passage TwoQuestions 51 to 55 are based on the following passage.For the past several decades, it seems there’ s been a general consensus on how to get ahead in America: Get a college education, find a reliable job, and buy your own home. But do Americansstill believe in that path, and if they do, is it attainable?The most recent National Journal poll asked respondents about the American dream, what ittakes to achieve their goals, and whether or not they felt a significant amount of control over theirability to be successful. Overwhelmingly, the results show that today, the idea of the Americandream — and what it takes to achieve it—looks quite different than it did in the late 20th century.By and large, people felt that their actions and hard work — not outside forces — werethedeciding factor in how their lives turned out. But respondents had decidedly mixed feelings aboutwhat actions make for a better life in the current economy.In the last seven years, Americans have grown more pessimistic about the power of education tolead to success. Even though they see going to college as a fairly achievable goal, a majority52 percent — thinkthat young people do not need a four-year college education in order to besuccessful.Miguel Maeda, 42, who has a master’ s degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability hisparents and grandparents never did.While some, like Maeda, emphasized the value of the degree rather than the education itself,others still see college as a way to gain new perspectives and life experiences.Sixty-year-old Will Fendley, who had a successful career in the military and never earned acollege degree, thinks “ personal drive ” is far more important than just going to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook, are the necessary ingredients for a successful life in America.51. It used to be commonly acknowledged that to succeed in America, one had to have ______.A) an advanced academic degree C) a firm belief in their dreamB) an ambition to get ahead D) a sense of drive and purpose52.What is the finding of the latest National Journal poll concerning the American dream?A) More and more Americans are finding it hard to realize.B) It remains alive among the majority of American people.C) Americans ’ idea of it has changed over the past few decades. D)An increasing number of young Americans are abandoning it.53.What do Americans now think of the role of college education in achieving success?A) It still remains open to debate.B) It has proved to be beyond doubt.C) It is no longer as important as it used to be.D) It is much better understood now than ever.54.How do some people view college education these days?A) It promotes gender equality.C) It adds to cultural diversity.B) It needs to be strengthened.D) It helps broaden their minds.55. What is one factor essential to success in America, according to Will Fendley?A)A desire to learn and to adapt.B)A strong sense of responsibility. C)A willingness to commit oneself.D)A clear aim and high motivation.Part IV Translation(30 minutes) Directions: For this part, you are allowed SO minutes to translate a passage from Chinese into English.

One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years. She noticed there was a real void in quality STEM education at all 27 of the public educational system. She said, "I started Engineering For Kids (EFK) after noticing a real lack of math, science and engineering programs to 28 my own kids in. "She decided to start an afterschool program where children 29 in STEM-based competitions. The club grew quickly and when it reached控Q members and the kids in the program won several state 30 , she decided to devote all her time to cultivating and 31 it. The global business EFK was born.Dori began operating EFK out of her Virginia home, which she then expanded to 32 recreation centers. Today, the EFK program 33 over 144 branches in 32 states within the United States and in 21 countries. Sales have doubled from MYM5 million in 2014 to MYMlO million in 2015, with 25 new branches planned for 2016. The EFK website states, "Our nation is not 34 enough engineers.

Each paragraph is marked with a letter: Answer the questions bymarking the corresponding letter on Answer Sheet 2.Why aren't you curious about what happened?A)" You suspended Ray Rice after our video, " a reporter from TMZ challenged National Football LeagueCommissioner Roger Goodell the other day. "Why didn't you have the curiosity to go to the casino (赌场）yourself?" The implication of the question is that a more curious commissioner would have found a way to get the tape.B)The accusation of incuriosity is one that we hear often ,carrying the suggestion that there is something wrong withnot wanting to search out the truth. "I have been bothered for a long time about the curious lack of curiosity, "said a Democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an assistant to New Jersey Governor Chris Christie who chose not to ask hard questions about the George Washington Bridge traffic scandal. "Isn't the mainstream media the least bit curious about what happened?" wrote conservative writer Jennifer Rubin earlier this year, referring to the attack on Americans in Benghazi ,Libya.C)The implication, in each case, is that curiosity is a good thing, and a lack of curiosity is a problem. Are suchaccusations simply efforts to score political points for one's party? Or is there something of particular value about curiosity in and of itself?D)The journalist Ian Leslie, in his new and enjoyable book Curious: The Desire to Know and Why Your FutureD ep ends on It ,insists that the answer to that last question is'Yes'. Leslie argues that curiosity is a much­overlooked human virtue, crucial to our success, and that we are losing it.E)We are suffering, he writes, from a " s erendipity deficit. "The word " serendipity" was coined by HoraceWalpole in an 1854 letter, from a tale of three princes who "were always making discoveries, by accident, of things they were not in search of. " Leslie worries that the rise of the Internet ,among other social and technological changes, has reduced our appetite for aimless adventures. No longer have we the inclination to let ourselves wander through fields of knowledge, ready to be surprised. Instead, we seek only the information we want.F)Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. Wewi且see unimaginative governments and dying corporations make disastrous decisions. We will lose a vital part of what has made humanity as a whole so successful as a species.G)Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious. Inthe U.S. and Europe, for example, the rise of the Internet has led to a declining consumption of news from outside the reader's borders. But not everything is to be blamed on technology. The decline in interest in literary fiction is also one of the causes identified by Leslie. Reading literary fiction, he says, makes us more curious.H)Moreover, in order to be curious, "you have to be aware of a gap in your knowledge in the first place. "Although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don't know, he's surely right to point out that the problem is growing: "Google can give us the powerful illusion that all questions have definite answers. "I)Indeed ,Google ,for which Leslie expresses admiration ,is also his frequent whipping boy (替罪羊）. He quotes Google co-founder Larry Page to the effect that the "perfect search engine" will "understand exactly what I meanand give me back exactly what I want. "Elsewhere in the book, Leslie writes: "Google aims to save you from the thirst of curiosity altogether. "J)Somewhat nostalgically (怀旧地），he quotes John Maynard Keynes's justly famous words of praise to the bookstore: " O ne should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in as curiosity dictates, should be an afternoon's entertainment. "If only!K)Citing the work of psychologists and cognitive (认知的）scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key factor—and a difficult one to preserve. If not cultivated, it will not survive: "Childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone. "L)School education, he warns, is often conducted in a way that makes children incurious. Children of educated and upper-middle-class parents turn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on.M)Although Leslie's book isnl about politics, he doesn't entirely shy away from the problem. Political leaders, like leaders of other organizations, should be curious. They should ask questions at crucial moments. There are serious consequences ,he warns ,in not wanting to know.N)He presents as an example the failure of the George W. Bush administration to prepare properly for the after­effects of the invasion of Iraq. According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the "unknown unknowns" were mistaken. Rumsfeld's idea, Leslie writes, "wasn't absurd—it was smart. "He adds, "The tragedy is that he didn't follow his own advice."0)All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples ischarging, in a different way, that someone in authority is intentionally being incurious. I leave it to the reader's political preference to decide which, if any, charges should stick. But let's be careful about demanding curiosity about the other side's weaknesses and remaining determinedly incurious about our own. We should be delighted to pursue knowledge for its own sake—even when what we find out is something we didn't particularly want to know.36.To be curious, we need to realize fi江st of all that there are many things we don't know.37.According to Leslie, curiosity is essential to one's success.38.We should feel happy when we pursue knowledge for knowledge's sake.39.Political leaders'lack of curiosity will result in bad consequences.40.There are often accusations about politicians'and the media's lack of curiosity to find out the truth.41.The less curious a child is, the less knowledge the child may turn out to have.42.It is widely accepted that academic accomplishment lies in both intelligence and diligence.43. V isiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44. B oth the rise of the Internet and reduced appetite for literary fiction contribute to people's declining curiosity.45. M ankind wouldn't be so innovative without curiosity.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a "disease. "On the other hand, scientists are increasingly learning that aging and biological age are two different things ,and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments." I t unties the hands of the pharmaceutical (制药的）industry so that they can begin treating the disease and not just the side effects , " he said." R ight now ,people think of aging as natural and something you can't control , " he said. "In academic circles , people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.But if aging were recognized as a disease, he said, "It would attract funding and change the way we do health care. What matters is understanding that aging is curable. ""It was always known that the body accumulates damage, " he added. "The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions. "Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them."There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease, " Hayflick said. "Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years."46. W hat do people generally believe about aging?A)It should cause no alarm whatsoever.C)It should be regarded as a kind of disease.47. H ow do many scientists view aging now?A)It might be prevented and treated.C)It results from a vitamin deficiency.B)They just cannot do anything about it. D)They can delay it with advances in science.B)It can be as risky as heart disease.D)It is an irreversible biological process.48. W hat does Alex Zhavoronkov think of "describing aging as a disease" ?A)It will prompt people to take aging more seriously.B)It will greatly help reduce the side effects of aging.C)It will free pharmacists from the conventional beliefs about aging.D)It will motivate doctors and pharmacists to find ways to treat aging.49. W hat do we learn about the medical community?A)They now have a strong interest in research on aging.B)They differ from the academic circles in their view on aging.C)They can contribute to people's health only to a limited extent.D)They have ways to intervene in people's aging process.50.What does Professor Leonard Hayflick believe?A)The human lifespan cannot be prolonged.B)Aging is hardly separable from disease.C)Few people can live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passage.Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring (指导），and have better odds of being hired. Studies show they're also perceived as more competent than women in STEM (Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too."Say, you know, this is the best student I've ever had," says KuheliDutt, a social scientist and diversity officer at Columbia University's Lamont campus. "Compare those excellent letters with a merely good letter:'The candidate was productive, or intelligent, or a solid scientist or something that's clearly solid praise,'but nothing that singles out the candidate as exceptional or one of a kind. "Dutt and her colleagues studied more than 1 , 200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared with their male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than outstanding letters of recommendation."We're not trying to assign blame or criticize anyone or call anyone consciously sexist. Rather, the point is to use the results of this study to open up meaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level. " Which may lead to some recommendations for the letter writers themselves.51.What do we learn about applicants to postdoctoral positions in geosciences?A)There are many more men applying than women.B)Chances for women to get the positions are scarce.C)More males than females are likely to get outstanding letters of recommendation.D)Male applicants have more interest in these positions than their female counterparts.52.What do studies about men and women in scientific research show?A)Women engaged in postdoctoral work are quickly catching up.B)Fewer women are applying for postdoctoral positions due to gender bias.C)Men are believed to be better able to excel in STEM disciplines.D)Women who are keenly interested in STEM fields are often exceptional.53.What do the studies find about the recommendation letters for women applicants?A)They are hardly ever supported by concrete examples.B)They contain nothing that distinguishes the applicants.C)They provide objective information without exaggeration.D)They are often filled with praise for exceptional applicants.54.What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A)They asked unbiased scholars to evaluate them.B)They invited women professionals to edit them.C)They assigned them randomly to reviewers.D)They deleted all information about gender.55.What does Dutt aim to do with her study?A)Raise recommendation writers'awareness of gender bias in their letters.B)Open up fresh avenues for women post-doctors to join in research work.C)Alert women researchers to all types of gender bias in the STEM disciplines.D)Start a public discussion on how to raise women's status in academic circles.Part IV Translation (30 minutes) Directions : 的r this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

2017 年12 月大学英语四级考试真题答案与详解（第1 套）Part I Writing审题思路：父母与子女的关系是一个老生常谈的话题，学生自己也会非常有感触、有话说。

因此，关键是如何组织语言，并把重点落脚到“how”上面。

如果采用我们一贯熟悉的“三点式”来讲怎么做，当然无可厚非。

不过，也可以换一种思路，重点从子女如何做下笔，并分析原因，使文章显得有理有据。

考场上时间紧张，考生思维也易受局限，不管从哪个角度写，一定要先列好提纲，理顺思路。

高分范文：Communication Is the Best Gift for ParentsThe relationship between parents and children is an eternal and universal topic for mankind. Our relationship with parents might be different at different ages. And for young people at their 20s, I think it will depend more on what children do.The reason why I say so is that as we grow up, our parents who were our idols before gradually get old and even out-dated. However hard efforts they make, they could not catch up with our steps, leading to the so-called invisible generation gap. Thus, if we cannot slow down our pace, there will definitely be an awkward silence between parents and us, which is not rare now. As a result, young people should talk more with parents to share our feelings and to understand each other better.Everyone wants loving parents who are open and supportive. Only through frequent communication with them, can we establish such a harmonious relationship.全文翻译：交流是给父母的最好的礼物对人类而言，父母与子女的关系是一个永恒而又普通的话题。

During this decade new forms of entertainment, commerce, research, and communication became commonplace in the U. S. The driving force behind much of this change was a(n) 26 popularly known as the Internet.The Internet was developed during the 1970s by the Department of Defense. In the case of an attack, 血litary advisers suggested the 27 of being able to operate one computer from another tern血al.In the early days, the Internet was used mainly by scientists to communicate with other scientists. The Internet 28 government control until 1984.One early problem faced by Internet users was speed. Phone lines could only transmit information at a 29 rate. The development of fi ber-optic (光纤）cables allowed for billions of bits of information to be received every minute. Companies like Intel developed faster microprocessors, so personal computers could process the 30 signals at a more rapid rate.In the early 1990s, the World Wide Web was developed, in large part, for 31 purposes. Corporations created home pages where they could place text and graphics to sell products. Soon airline tickets, hotel 32 , and even cars and homes could be purchased online. Universities 33 research data on the Internet, so students could find 34 inforn皿ion without leaving their dormitories. Companies soon discovered that work could be done at home and 35 online, so a whole new class of telecommuters began to earn a living from home offices unshaven and wearing pa j amas (睡衣）．Section B A)advantageD)e q uippedG)limitedJ)occupationsM)reservationsB)commercialE)mcommgH)localK)postedN)submittedC)conservatrnnF)innovationI)maintainedL)remainedO)valuableDirections : In this section ,you are going to read a passage with ten statements attached to it.

Each paragraph is marked with a letter: Answer the questions bymarking the corresponding letter on Answer Sheet 2.The Health Benefits of KnittingA)About 15 years ago, I was invited to join a knitting group. I agreed to give it a try.B)My mother had taught me to knit at 15, and I knitted in class throughout college and for a few years thereafter.Then decades passed without my touching a knitting needle. But within two Mondays in the group, I was hooked, not only on knitting but also on crocheting (钩织），and I was on my way to becoming a highlyproductive crafter.C)I've made countless baby blankets, sweaters, scarves, hats, caps for newborns. I take a knitting project with meeverywhere, especially when I have to sit still and listen. As I discovered in college, when my hands are busy, my mind stays focused on the here and now.D)It seems, too, that I'm part of a national renewal of interest in needle and other handicrafts (手工艺）. TheCraft Yarn Council reports that a third of women ages 25-35 now knit or crochet. Even men and schoolchildren are swelling the ranks ,among them my friend's three small grandsons. Last April ,the council created a " S titch Away Stress" campaign in honor of National Stress Awareness Month. Dr. Herbert Benson, a pioneer in mind/ body medicine and author of The Relaxation Response, says that the repetitive action of needlework can induce a relaxed state like that associated with meditation (沉思）and yoga. Once you get beyond the initial learning curve, knitting and crocheting can lower heart rate and blood pressure.E)But unlike meditation, craft activities result in tangible and often useful products that can e呻ance self-esteem. I keep photos of my singular accomplishments on my cellphone to boost my spirits when needed.F)Since the 1990s, the council has surveyed hundreds of thousands of knitters and crocheters, who routinely list stress relief and creative fulfillment as the activities'main benefits. Among them is the father of a prematurely born daughter who reported that during the baby's five weeks in the intensive care unit, " learning how to knit infant hats gave me a sense of purpose during a time that I felt very helpless. It's a hobby that I've stuck with, and it continues to help me cope with stress at work, provide a sense of order in hectic (忙乱的）days, and allow my brain time to solve problems. "G)A recent email from the yam (纺纱）company Red Heart titled "Health Benefits of Crocheting and Knitting"prompted me to explore what else might be known about the health value of activities like knitting. My research revealed that the rewards go well beyond replacing stress and anxiety with the satisfaction of creation.H)For example, Karen Hayes, a life coach in Toronto, conducts knitting therapy programs, including K血to Quitto help smokers give up the habit, and Knit to Heal for people coping with health crises, like a cancer diagnosis or serious illness of a family member. Schools and prisons with craft programs report that they have a calming effect and enhance social skills. And having to follow instructions on complex craft projects can improve children's math skills.I)Some people find that craftwork helps them control their weight. Just as it's challenging to smoke while knitting, when hands are holding needles and hooks, there's less snacking and mindless eating out of boredom.J)I've found that my handiwork with yarn has helped my arthritic (患关节炎的）fingers remain more dexterous (灵巧的）as I age. A woman encouraged to try knitting and crocheting after developing an autoimmune disease that caused a lot of hand pain reported on the Craft Yam Council site that her hands are now less stiff and painful. K)A 2009 University of British Columbia study of 38 women with an eating disorder who were taught to knit found that learning the craft led to significant improvements. Seventy-four percent of the women said the activity lessened their fears and kept them from thinking about their problem.L)BetsanCorkhill, a wellness coach in Bath, England, and author of the book Knit for Health & Wellness , established a website, Stitchlinks, to explore the value of what she calls therapeutic knitting. Among her respondents ,54 percent of those who were clinically depressed said that knitting made them feel happy or very happy. In a study of 60 self-selected people with persistent pain, Ms. Corkhill and colleagues reported that knitting enabled them to redirect their focus, reducing their awareness of pain. She suggested that the brain can process just so much at once, and that activities like knitting and crocheting make it harder for the brain to register pain signals. Perhaps most exciting is research that suggests that crafts like knitting and crocheting may help to keep off a decline in brain function with age. In a 2011 study, researchers led by Dr. YonasGeda at theMayo Clinic in Rochester interviewed a random (随机的）sample of 1,321 people ages 70-89 , most of whom were cognitively (在认知方面）normal, about the cognitive activities they engaged in late in life. The study, published in the Journal of Neuropsychiatry & Clinical Neurosciences , found that those who engaged in crafts like knitting and crocheting had a diminished chance of developing mild cognitive disorder and memory loss.M)Although it is possible that only people who are cognitively healthy would pursue such activities, those who read newspapers or magazines or played music did not show similar benefits. The researchers speculate that craft activities promote the development of nerve pathways in the brain that help to maintain cognitive health.N)In support of that suggestion, a 2014 study by Denise C. Park of the University of Texas at Dallas and colleagues demonstrated that learning to knit or do digital photography enhanced memory function in older adults. Those who engaged in activities that were not intellectually challenging, either in a social group or alone, did not show such improvements.0)Given that sustained social contacts have been shown to support health and a long life, those wishing tomaximize the health value of crafts might consider joining a group of like-minded folks. I for one try not to missa single weekly meeting of my肋itting group.36.When the author was a college student, she found that knitting helped her concentrate.37.Knitting can help people stay away from tobacco.38.Even men and children are now joining the army of knitters.39.Being a member of a crafts group enhances one's health and prolongs one's life.40.Knitting diverts people's attention from their pain.41.The author learnt to knit as a teenager, but it was not until she was much older that she became keenly interested.42.When people are knitting, they tend to eat fewer snacks.43.Survey findings show that knitting can help people relieve stress.44.According to a study, knitters and crocheters are less likely to suffer mild cognitive damage.45.The products of knitting can increase one's sense of self-respect.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Nobody really knows how big Lagos is. What's indisputable is that it's growing very quickly.Between now and 2050 , the urban population of Africa could triple. Yet cities in sub-Saharan Africa are not getting richer the way cities in the rest of the world have. Most urban Africans live in slums (贫民窟）；migrants are often not much better off than they were in the countryside. Why?The immediate problem is poverty. Most of Africa is urbanising at a lower level of income than other regions of the world did. That means there's little money around for investment that would make cities liveable and more productive. Without upgrades and new capacity, bridges, roads and power systems are unable to cope with expanding populations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense and unpredictability, things that keep investors away.In other parts of the world, increasing agricultural productivity and industrialisation went together. More productive farmers meant there was a surplus that could feed cities; in turn, that created a pool of labour forfactories. But African cities are different. They are too often built around consuming natural resources. Government is concentrated in capitals ,so is the money. Most urban Africans work for a small minority of the rich, who tend to be involved in either cronyish (有裙带关系的）businesses or politics. Since African agriculture is still broadly unproductive, food is imported, consuming a portion of revenue.So what can be done? Though African countries are poor, not all African cities are. In Lagos, foreign oil workers can pay as much as MYM65 , 000 per year in rent for a modest apartment in a safe part of town. If that income were better taxed, it might provide the revenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city's population grows by 5% a year, it is difficult to keep up.46.What do we learn from the passage about cities in sub-Saharan Africa?A)They h a ve more slums than other c1t1es m the world.B)They are growing fast without becoming richer.C)They are as modernised as many cities elsewhere.D)They attract migrants who want to be better off.47.What does the author imply about urbanisation in other parts of the world?A)It benefited from the contribution of immigrants.B)It started when people's income was relatively high.C)It benefited from the accelerated rise in productivity.D)It started with the improvement of people's livelihood.48.Why is sub-Saharan Africa unappealing to investors?A)It lacks adequate transport facilities.B)The living expenses there are too high.C)It is on the whole too densely populated.D)The local governments are corrupted.49.In what way does the author say African cities are different?A)They have attracted huge numbers of farm labourers.B)They still rely heavily on agricultural productivity.C)They have developed at the expense of nature.D)They depend far more on foreign investment.50.What might be a solution to the problems facing African cities?A)Lowering of apartment rent.B)B e tter educauon for residents.C)More rational overall planning.D)A more responsible government.Passage TwoQuestions 51 to 55 are based on the following passage.For the past several decades ,it seems there's been a general consensus on how to get ahead in America: Get a college education, find a reliable job, and buy your own home. But do Americans still believe in that path, and if they do ,is it attainable?The most recent National Journal poll asked respondents about the American dream, what it takes to achieve their goals ,and whether or not they felt a significant amount of control over their ability to be successful. Overwhelmingly ,the results show that today, the idea of the American dream—and what it takes to achieve it-looks quite different than it did in the late 20th century.By and large ,people felt that their actions and hard work—not outside forces—were the deciding factor in howtheir lives turned out. But respondents had decidedly mixed feelings about what actions make for a better life in the current economy.In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority—52 percent—think that young people do not need a four-year college education in order to be successful.Miguel Maeda, 42 ,who has a master's degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability his parents and grandparents never did.While some, like Maeda, emphasized the value of the degree rather than the education itself, others still see college as a way to gain new perspectives and life experiences.Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, thinks "personal drive" is far more important than just going to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook, are the necessary ingredients for a successful life in America.51.It used to be commonly acknowledged that to succeed in America, one had to have.A)an advanced academic degree B)an ambition to get aheadC)a firm belief in their dream D)a sense of drive and purpose52.What is the finding of the latest National Journal poll concerning the American dream?A)More and more Americans are finding it hard to realize.B)It remains alive among the majority of American people.C)Americans'idea of it has changed over the past few decades.D)An increasing number of young Americans are abandoning it.53.What do Americans now think of the role of college education in achieving success?A)It still remains open to debate.B)It has proved to be beyond doubt.C)It is no longer as important as it used to be.D)It is much better understood now than ever.54.How do some people view college education these days?A)It promotes gender e q uality.B)It needs to be strengthened.C)It adds to cultural diversity.D)It helps broaden their minds.55.What is one factor essential to success in America, according to Will Fendley?A)A desire to learn and to adapt.B)A strong sense of responsibility.C)A willingness to commit oneself.D)A clear aim and high motivation.Part IV Translation (30 minutes) Directions : 几r this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

One educator named Dori Roberts decided to do something to change this system. Dori taught high school engineering for 11 years.She noticed there was a real void in quality STEM education at all 27 of the public educational system. She said,“I started Engineering for Kids (EFK)after noticing a real lack of math, science and engineering programs to 28 my own kids in.”She decided to start an after school program where children 29 in STEM-based competitions.The club grew quickly and when it reached 180 members and the kids in the program won several state 30 .

Today, the EFK program 33 over 144 branches in 32 states within theUnited States and in 21 countries. Sales have doubled from $5 million in 2014 to $10 million in 2015,with 25 new branches planned for 2016. The EFK website states, “Our nation is not 34 enough engineers. Our philosophy is to inspire kids at a young age to understand that engineering is a great 35 .”Section BWhy aren't you curious about what happened?A)"You suspended Ray Rice after our video,” a reporter from TMZ challenged National Football League Commissioner Roger Goodell the other day. "Why didn't you have the curiosity to go to the casino (赌场) yourself? "The implication of the question is that a more curious commissioner would have found a way to get the tape.B) The accusation of incuriosity is one that we hear often carrying the suggestion that there is something wrong with not wanting to search out the truth. " I have been bothered for a long time about the curious lack of curiosity, "said a democratic member of the New Jersey legislature back in July, referring to an insufficiently inquiring attitude on the part of an the George Washington Bridge traffic scandal. "Isn’t the mainstream media the least bit curious about what happened? "wrote conservative writer Jennifer Rubin earlier this year referring to the attack on Americans in Benghazi, Libya.C) The implication, in each case is that curiosity is a good thing, and a lack of curiosity is a problem.Are such accusations simply efforts to score political points for one's party? Or is here something of particular value about curiosity in and of itself.D) The journalist Ian Leslie in his new and enjoyable book Curious: The Desire to Know and Why Your Future Depends on it, insists that the answer to that last question is “Yes”. Leslie argues that curiosity is a much-overlooked human virtue, crucial to our success, and that we are losing it.E)we are suffering. he writes from a" deficit" the word""was coined by Horace Walpole in an 1854 letter from a tale of three princes who were always making discoveries by accident, of things they were not in search of, " worries that the rise of the internet, among other social and technological changes, has reduced our appetite for aimless adventures no longer have we the inclination to let ourselves wander through fields of knowledges, ready to be surprised. instead, we seek only the information we want.F)Why is this a problem? Because without curiosity we will lose the spirit of innovation and entrepreneurship. We will see unimaginative governments and dying corporations make disastrous decisions.We will lose a vital part of what has made humanity as a whole so successful as a species.G)Leslie presents considerable evidence for the proposition that the society as a whole is growing less curious. In the U.S. and Europe, for example, the rise of the Internet has led to a declining consumption of news from outside the reader's borders .But not everything is to be blamed on technology.The decline in interest in literary fiction is also one of the causes identified by Leslie.Reading literary fiction,he says ,make us more curious.H)Moreover,in order to be curious, "you have to be aware of a gap in your knowledge in the first place. "although Leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don't know, he's surely right to point out that the problem is growing: "Google can give us the powerful illusion that a questions have definite answers.”I）Indeed, Google, for which Leslie express admiration, is also his frequent whipping boy(替罪羊). He quotes Google co-founder Larry Page to the effect that the “perfect search engine” will “understand exactly what I mean and give me back exactly what I want. “Elsewhere in the book,” Leslie writes: "Google aims to save you from the thirst of curiosity altogether.”J) Somewhat nostalgically(怀旧地), he quotes John Maynard Keynes's justly famous words of praise to the bookstore: "One should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye. To walk the rounds of the bookshops, dipping in ascuriosity dictates, should be an afternoon’s entertainment. "if only!K) Citing the work of psychologists and cognitive( 认知的)scientists, Leslie criticizes the received wisdom that academic success is the result of a combination of intellectual talent and hard work. Curiosity, he argues, is the third key factor--and a difficult one to preserve. If not cultivated, it will not survive “childhood curiosity is a collaboration between child and adult. The surest way to kill it is to leave it alone.”L) School education, he warns, is often conducted in a way that makes children incurious. Children of educated and upper-middle-class parents turn out to be far more curious, even at early ages, than children of working class and lower class families. That lack of curiosity produces a relative lack of knowledge, and the lack of knowledge is difficult if not impossible to compensate for later on.M）Although Leslie's book isn't about politics, he doesn't entirely shy away from the problem.Political leaders,like leader of other organizations, should be curious. They should ask questions at crucial moments. There are serious consequences, he warns, in not wanting to know.N) He presents as an example the failure of the George W. Bush administration to prepare properly for the after-effects of the invasion of Iraq. According to Leslie, those who ridiculed former Defense Secretary Donald Rumsfeld for his 2002 remark that we have to be wary of the “unknown unknowns” were mistaken. Rumsfeld's idea, Leslie writes, “wasn’t absurd--it was smart . "he adds, "The tragedy is that he didn't follow his own advice."O) All of which brings us back to Goodell and the Christie case and Benghazi. Each critic in those examples is charging, in a different way, that someone in authority is intentionally being curious. I leave it to the reader's political preference to decide which, if any, charges should stick. But let's be careful about demanding curiosity about the other side's weaknesses and remanding determinedly incurious about our own. We should be delighted to pursue knowledge for its own sake—even when what we find out is something we didn't particularly want to know.36. To be curious, we need to realize first of all that there are many things we don’t know.37. According to Leslie, curiosity is essential to one's success.38. We should feel happy when we pursue knowledge for knowledge's sake.39. Political leaders' lack of curiosity will result in bad consequences.40. There are often accusations about politicians' and the media's lack of curiosity to find out the truth.41. The less curious a child is, the less knowledge the child may turn out to have.42. It is widely accepted that academic accomplishment lies in both intelligence and diligence.43. Visiting a bookshop as curiosity leads us can be a good way to entertain ourselves.44. Both the rise of the Internet and reduced appetite for literary fiction contribute to people’s declining curiosity.45.Mankind wouldn't be so innovative without curiosity.Section CDirections: There are 2 passages in this section.

For each of them there are four choices marked A), B), C) and D). You should decide on the best choice andmark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a "disease. "On the other hand, scientists are increasingly learning that aging and biological age are two different things ,and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency.Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments." I t unties the hands of the pharmaceutical (制药的）industry so that they can begin treating the disease and not just the side effects , " he said." R ight now ,people think of aging as natural and something you can't control , " he said. "In academic circles , people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range.But if aging were recognized as a disease, he said, "It would attract funding and change the way we do health care. What matters is understanding that aging is curable. ""It was always known that the body accumulates damage, " he added. "The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions. "Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them."There're many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease, " Hayflick said. "Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years."46. W hat do people generally believe about aging?A)It should cause no alarm whatsoever.C)It should be regarded as a kind of disease.47. H ow do many scientists view aging now?A)It might be prevented and treated.C)It results from a vitamin deficiency.B)They just cannot do anything about it. D)They can delay it with advances in science.B)It can be as risky as heart disease.D)It is an irreversible biological process.48. W hat does Alex Zhavoronkov think of "describing aging as a disease" ?A)It will prompt people to take aging more seriously.B)It will greatly help reduce the side effects of aging.C)It will free pharmacists from the conventional beliefs about aging.D)It will motivate doctors and pharmacists to find ways to treat aging.49. W hat do we learn about the medical community?A)They now have a strong interest in research on aging.B)They differ from the academic circles in their view on aging.C)They can contribute to people's health only to a limited extent.D)They have ways to intervene in people's aging process.50.What does Professor Leonard Hayflick believe?A)The human lifespan cannot be prolonged.B)Aging is hardly separable from disease.C)Few people can live up to the age of 92.D) Heart disease is the major cause of aging.Passage TwoQuestions 51 to 55 are based on the following passage.Female applicants to postdoctoral positions in geosciences were nearly half as likely to receive excellent letters of recommendation, compared with their male counterparts. Christopher Intagliata reports.As in many other fields, gender bias is widespread in the sciences. Men score higher starting salaries, have more mentoring (指导），and have better odds of being hired. Studies show they're also perceived as more competent than women in STEM (Science, Technology, Engineering, and Mathematics) fields. And new research reveals that men are more likely to receive excellent letters of recommendation, too."Say, you know, this is the best student I've ever had," says KuheliDutt, a social scientist and diversity officer at Columbia University's Lamont campus. "Compare those excellent letters with a merely good letter:'The candidate was productive, or intelligent, or a solid scientist or something that's clearly solid praise,'but nothing that singles out the candidate as exceptional or one of a kind. "Dutt and her colleagues studied more than 1 , 200 letters of recommendation for postdoctoral positions in geoscience. They were all edited for gender and other identifying information, so Dutt and her team could assign them a score without knowing the gender of the student. They found that female applicants were only half as likely to get outstanding letters, compared with their male counterparts. That includes letters of recommendation from all over the world, and written by, yes, men and women. The findings are in the journal Nature Geoscience.Dutt says they were not able to evaluate the actual scientific qualifications of the applicants using the data in the files. But she says the results still suggest women in geoscience are at a potential disadvantage from the very beginning of their careers starting with those less than outstanding letters of recommendation."We're not trying to assign blame or criticize anyone or call anyone consciously sexist. Rather, the point is to use the results of this study to open up meaningful dialogues on implicit gender bias, be it at a departmental level or an institutional level or even a discipline level. " Which may lead to some recommendations for the letter writers themselves.51.What do we learn about applicants to postdoctoral positions in geosciences?A)There are many more men applying than women.B)Chances for women to get the positions are scarce.C)More males than females are likely to get outstanding letters of recommendation.D)Male applicants have more interest in these positions than their female counterparts.52.What do studies about men and women in scientific research show?A)Women engaged in postdoctoral work are quickly catching up.B)Fewer women are applying for postdoctoral positions due to gender bias.C)Men are believed to be better able to excel in STEM disciplines.D)Women who are keenly interested in STEM fields are often exceptional.53.What do the studies find about the recommendation letters for women applicants?A)They are hardly ever supported by concrete examples.B)They contain nothing that distinguishes the applicants.C)They provide objective information without exaggeration.D)They are often filled with praise for exceptional applicants.54.What did Dutt and her colleagues do with the more than 1,200 letters of recommendation?A)They asked unbiased scholars to evaluate them.B)They invited women professionals to edit them.C)They assigned them randomly to reviewers.D)They deleted all information about gender.55.What does Dutt aim to do with her study?A)Raise recommendation writers'awareness of gender bias in their letters.B)Open up fresh avenues for women post-doctors to join in research work.C)Alert women researchers to all types of gender bias in the STEM disciplines.D)Start a public discussion on how to raise women's status in academic circles.Part IV Translation (30 minutes) Directions : 的r this part, you are allowed 30 minutes to translate a passage f rom Chinese into English.

During this decade new forms of entertainment, commerce, research, and communication became commonplace in the U. S. The driving force behind much of this change was a (n) 26 popularly known as the Internet.The Internet was developed during the 1970s by the Department of Defense. In the case of an attack, military advisers suggested the 27 of being able to operate one computer from another terminal. In the early days, the Internet was used mainly by scientists to communicate with other scientists. The Internet 28 under government control until 1984.One early problem faced by Internet users was speed. Phone lines could only transmit information at a 29 rate. The development of fiber-optic (光纤)cables allowed for billions of bits of information to be received every minute. Companies like Intel developed faster microprocessors, so personal computers could process the 30 signals at a more rapid rate.In the early 1990s, the World Wide Web was developed, in large part, for 31 purposes. Corporations created home pages where they could place text and graphics to sell products. Soon airline tickets, hotel 32 , and even cars and homes could be purchased online. Universities 33 research data on the Internet, so students could find 34 information without leaving their dormitories. Companies soon discovered that work could be done at home and 35 online, so a whole new class of telecommuters began to earn a living from home offices unshaven andSection BDirections:In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The Health Benefits of KnittingA) About 15 years ago, I was invited to join a knitting group. I agreed to give it a try.B) My mother had taught me to knit at 15, and I knitted in class throughout college and for a few years thereafter. Then decades passed without my touching a knitting needle. But within two Mondays in the group, I was hooked, not only on knitting but also on crocheting (钩织), and I was on my way to becoming a highly productive crafter.C) I’ve made countless baby blankets, sweaters, scarves, hats, caps for newborns. I take a knitting project with me everywhere, especially when I have to sit still and listen. As I discovered in college, when my hands are busy, my mind stays focused on the here and now.D) It seems, too, that I’m part of a national renewal of interest in needle and other handicrafts (手工艺).The Craft Yam Council reports that a third of women ages 25-35 now knit or crochet. Even men and schoolchildren are swelling the ranks, among them my Mend’s three small grandsons. Last April, the council created a Stitch Away Stress” campaign in honor of National Stress Awareness Month. Dr. Herbert Benson, a pioneer in mind/body medicine and author of The Relaxation Response, says that the repetitive action of needlework can induce a relaxed state like that associated with meditation (沉思) and yoga. Once you get beyond the initial learning curve, knitting and crocheting can lower heart rate and blood pressure.E) But unlike meditation, craft activities result in tangible and often useful products that can enhance self-esteem. I keep photos of my singular accomplishments on my cellphone to boost my spirits when needed.F) Since the 1990s, the council has surveyed hundreds of thousands of knitters and crocheters, who routinely list stress relief and creative fulfillment as the activities’ main benefits. Among them is the father of a prematurely born daughter who reported that during the baby’s five weeks in the intensive care unit, “learning how to knit infant hats gave me a sense of purpose during a time that I felt very helpless. It’s a hobby that I’ve stuck with, and it continues to help me cope with stress at work, provide a sense of order in hectic (忙乱的) days, and allow my brain time to solve problems.”G) A recent email from the yam (纺纱) company Red Heart titled “Health Benefits of Crocheting and Knitting” prompted me to explore what else might be known about the health value of activities like knitting. My research revealed that the rewards go well beyond replacing stress and anxiety with the satisfaction of creation.H) For example, Karen Hayes, a life coach in Toronto, conducts knitting therapy programs, including Knit to Quit to help smokers give up the habit, and Knit to Heal for people coping with health crises, like a cancer diagnosis or serious illness of a family member. Schools and prisons with craft programs report that they have a calming effect and enhance social skills. And having to follow instructions on complex craft projects can improve children’s math skills.I) Some people find that craftwork helps them control their weight. Just as it’s challenging to smoke while knitting, when hands are holding needles and hooks, there’s less snacking and mindless eating out of boredom.J) I’ve found that my handiwork with yam has helped my arthritic (患关节炎的)fingers remain more dexterous (灵巧的) as I age. A woman encouraged to try knitting and crocheting after developing an autoimmune disease that caused a lot of hand pain reported on the Craft Yam Council site that her hands are now less stiff and painful.K) A 2009 University of British Columbia study of 38 women with an eating disorder who were taught to knit found that learning the craft led to significant improvements. Seventy-four percent of the women said the activity lessened their fears and kept them from thinking about their problem.L) Betsan Corkhill, a wellness coach in Bath, England, and author of the book Knit for Health & Wellness, established a website, Stitchlinks, to explore the value of what she calls therapeutic knitting. Among her respondents, 54 percent of those who were clinically depressed said that knitting made them feel happy or very happy. In a study of 60 self-selected people with persistent pain, Ms. Corkhill and colleagues reported that knitting enabled them to redirect their focus, reducing their awareness of pain. She suggested that the brain can process just so much at once, and that activities like knitting and crocheting make it harder for the brain to register pain signals. Perhaps most exciting is research that suggests that crafts like knitting and crocheting may help to keep off a decline in brain function with age. In a 2011 study, researchers led by Dr. Yonas Geda at the Mayo Clinic in Rochester interviewed a random (随机的) sample of 1,321 people ages 70-89, most of whom were cognitively (在认知方面) normal, about the cognitive activities they engaged in late in life. The study, published in the Journal of Neuropsychiatry & Clinical Neurosciences, found that those who engaged in crafts like knitting and crocheting had a diminished chance of developing mild cognitive disorder and memory loss.M) Although it is possible that only people who are cognitively healthy would pursue such activities, those who read newspapers or magazines or played music did not show similar benefits. The researchers speculate that craft activities promote the development of nerve pathways in the brain that help to maintain cognitive health.N) In support of that suggestion, a 2014 study by Denise C. Park of the University of Texas at Dallas and colleagues demonstrated that learning to knit or do digital photography enhanced memory function in older adults. Those who engaged in activities that were not intellectually challenging, either in a social group or alone, did not show such improvements.O) Given that sustained social contacts have been shown to support health and a long life, those wishing to maximize the health value of crafts might consider joining a group of like-minded folks.I for one try not to miss a single weekly meeting of my knitting group.36. When the author was a college student, she found that knitting helped her concentrate.37. Knitting can help people stay away from tobacco.38. Even men and children are now joining the army of knitters.39. Being a member of a crafts group enhances one’s health and prolongs one’s life.40. Knitting diverts people’s attention from their pain.41. The author learnt to knit as a teenager, but it was not until she was much older that she became keenly interested.42. When people are knitting, they tend to eat fewer snacks.43. Survey findings show that knitting can help people relieve stress.44. According to a study, knitters and crocheters are less likely to suffer mild cognitive damage.45. The products of knitting can increase one’s sense of self-respect.Section CDirections: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 to 50 are based on the following passage.Nobody really knows how big Lagos is. What’s indisputable is that it’s growing very quickly. Between now and 2050, the urban population of Africa could triple. Yet cities in sub-Saharan Africa are not getting richer the way cities in the rest of the world have. Most urban Africans live in slums (贫民窟); migrants are often not much better off than they were in the countryside. Why?The immediate problem is poverty. Most of Africa is urbanising at a lower level of income than other regions of the world did. That means there’s little money around for investment that would make cities liveable and more productive. Without upgrades and new capacity, bridges, roads and power systems are unable to cope with expanding populations. With the exception of South Africa, the only light rail metro system in sub-Saharan Africa is in Addis Ababa, Ethiopia. Traffic jam leads to expense and unpredictability, things that keep investors away.In other parts of the world, increasing agricultural productivity and industrialization went together. More productive farmers meant there was a surplus that could feed cities; in turn, that created a pool of labour for factories. But African cities are different. They are too often built around consuming natural resources. Government is concentrated in capitals, so is the money. Most urban Africans work for a small minority of the rich, who tend to be involved in either cronyish (有裙带关系的)businesses or politics. Since African agriculture is still broadly unproductive, food is imported, consuming a portion of revenue.So what can be done? Though African countries are poor, not all African cities are. In Lagos, foreign oil workers can pay as much as $65,000 per year in rent for a modest apartment in a safe part of town. If that income were better taxed, it might provide the revenue for better infrastructure. If city leaders were more accountable to their residents, they might favour projects designed to help them more. Yet even as new roads are built, new people arrive. When a city’s population grows by 5% a year, it is difficult to keep up.46. What do we learn from the passage about cities in sub-Saharan Africa?A) They have more slums than other cities in the world.B) They are growing fast without becoming richer.C) They are as modernised as many cities elsewhere.D) They attract migrants who want to be better off.47. What does the author imply about urbanisation in other parts of the world?A) It benefited from the contribution of immigrants.B) It started when people’s income was relatively high.C) It benefited from the accelerated rise in productivity.D) It started with the improvement of people’s livelihood.48. Why is sub-Saharan Africa unappealing to investors?A) It lacks adequate transport facilities.B) The living expenses there are too high.C) It is on the whole too densely populated.D) The local governments are corrupted.49. In what way does the author say African cities are different?A) They have attracted huge numbers of farm labourers.B) They still rely heavily on agricultural productivity.C) They have developed at the expense of nature.D) They depend far more on foreign investment.50. What might be a solution to the problems facing African cities?A) Lowering of apartment rent.C) More rational overall planning.B) Better education for residents.D) A more responsible government.Passage TwoQuestions 51 to 55 are based on the following passage.For the past several decades, it seems there’s been a general consensus on how to get ahead in America: Get a college education, find a reliable job, and buy your own home. But do Americans still believe in that path, and if they do, is it attainable?The most recent National Journal poll asked respondents about the American dream, what it takes to achieve their goals, and whether or not they felt a significant amount of control over their ability to be successful. Overwhelmingly, the results show that today, the idea of the American dream—and what it takes to achieve it—looks quite different than it did in the late 20th century.By and large, people felt that their actions and hard work—not outside forces—were the deciding factor in how their lives turned out. But respondents had decidedly mixed feelings about what actions make for a better life in the current economy.In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority— 52 percent—think that young people do not need a four-year college education in order to be successful.Miguel Maeda, 42, who has a master’s degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability his parents and grandparents never did.While some, like Maeda, emphasized the value of the degree rather than the education itself, others still see college as a way to gain new perspectives and life experiences.Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, thinks “personal drive” is far more important than just going to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook, are the necessary ingredients for a successful life in America.51. It used to be commonly acknowledged that to succeed in America, one had to have ______.A) an advanced academic degree C) a firm belief in their dreamB) an ambition to get ahead D) a sense of drive and purpose52. What is the finding of the latest National Journal poll concerning the American dream?A) More and more Americans are finding it hard to realize.B) It remains alive among the majority of American people.C) Americans’ idea of it has changed over the past few decades.D) An increasing number of young Americans are abandoning it.53. What do Americans now think of the role of college education in achieving success?A) It still remains open to debate.B) It has proved to be beyond doubt.C) It is no longer as important as it used to be.D) It is much better understood now than ever.54. How do some people view college education these days?A) It promotes gender equality.C) It adds to cultural diversity.B) It needs to be strengthened.D) It helps broaden their minds.55. What is one factor essential to success in America, according to Will Fendley?A) A desire to learn and to adapt.C) A willingness to commit oneself.B) A strong sense of responsibility.D) A clear aim and high motivation.Part IV Translation(30 minutes) Directions: For this part, you are allowed SO minutes to translate a passage from Chinese into English.
