You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.A rat or pigeon might not be the obvious choice to tend to someone who is sick, but these creatures have some 26 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 a 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 animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors （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.A) associated I) slightB) examine J) specifyC) indicate K) superiorD) nuisance L) suspiciousE) peak M) tipF) preventing N) treatedG) prohibiting O) visualH) sensitiveSection 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.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 the degree 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 issuestake-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. To say 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 did some 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, and essential work skill.”[D] He also says there is less chance of cheating with the in-class variety. In 2012, 125 students at Harvard were caught 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 going.[E] Following the Harvard scandal, Mary Miller, the former dean of students at Yale, made an impassioned appeal to her school’s professors to refrain fromtake-hone 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-based one, 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 research-oriented 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 take-home 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, butthere 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 stress may depend on their personaltest-taking abilities. There are people who always wait until the last minute, and make it much harder than it needs to be. And then there 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 toaccess the information as quickly. As another returning student at Columbia, Kate Marber, toldme, “We are learning not only all this information, but essentially how to learn again. Ourfellow students have just come out of high school. A lot has changed since we were last inschool.”[J] If nothing else, the situation has given my college son and me something to share, When Iasked his opinion on this matter, he responded, “I like in-class exams because the time isalready 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 inadvance, and then doing the actual test in class the ticking clock overhead.[K] Better yet, how about what one Hunter College professor reportedly did recently for her finalexam: She encouraged the class not to stress or even study, promising that, “It is going to be apiece of cake.” When the students came in, sharpened pencils in hand, there was not a bluebook in sight. Rather, they saw a large chocolate cake and they each were givena 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 thanthey 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 type ofcourse being taught.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 and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.Passage OneQuestions 46 and 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 “first-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 whenperformance might be affected the following day. She also knew from previous work conducted on birds and dolphins that these animals 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 environment 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 environment, Dr. Sasaki re-ran the experiment while presenting the sleeping participants with a mix of regularly timed beeps (蜂鸣声) 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. What did researchers find puzzling about the first-night effect?A) To what extent it can trouble people. C) What circumstances may trigger it.B) What role it has played in evolution. D) In what way it can be beneficial.47. What 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 dolphinsD) She conducted studies on birds’ and dolphins’ sleeping patterns.48. What did Dr. Sasaki do when she first did her experiment?A) She monitored the brain activity of participants sleeping in a new environment.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. What 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. What 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 todo 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 “no” 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 heath 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 should be the one to fix it. Men are more likely to face that dispute from the perspective of what benefitsthem most, whereas women may approach the same dispute from the perspective of what's the easiest and quickest way to resolve the problem-evenif 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 woman 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. C) The courage to admit failureB) The ability to delegate. D) A strong sense of responsibility.Part Ⅳ Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese intoEnglish.

Social skills help children to interact effectively with others and build healthy relationships. These skills are vital for success in school, work, and life in general.One of the best ways to help children develop social skills is through play. Play allows children to practice andmaster social, emotional, and cognitive skills in a relaxed and enjoyableenvironment. Through play, children learn valuable skills such as cooperation, sharing, problem-solving, and communication.There are different types of play that help in the development of social skills. Cooperative play is when children play and work together towards a common goal. This type of play helps children to learn teamwork and collaboration. Pretend play, on the other hand, allows children to develop empathy and understanding of others’ perspectives. They learn to take on different roles and pretend to be someone else, which helps in developing their social and emotional intelligence. Board games and group activities also promote social interaction and help children learn important skills such as taking turns, following rules, and resolving conflicts in a fair manner.Parents and educators play a crucial role in promoting social skills development. They can create opportunities for play and provide guidance and support. It is important for parents to encourage their children to engage in various types of play and provide them with age-appropriate toys and games. Educators can incorporate play-based learning activities in the classroom to foster social skills development.In conclusion, play is a valuable tool for social skills development. It allows children to practice and master important skills while having fun. Parents and educators should recognize the importance of play and provide opportunities and support for children to engage in different types of play.第二套The concept of time management is essential in today’s fast-paced world.

However, people’s view on it never come to consensus. Concerning it, both communication online and offline have their merits.For one thing, no one denies that communication online brings great convenience to us, especially to those who have friends or relatives in remote areas. Because the change makes it possible for them to have frequent chat. And, the way we contact with others is diverse. Video calls and voice message can both meet modern people’s satisfaction. For another, the change is also making us disconnected. Due to the availability, people are gradually reluctant to have face-to-face communication with surrounding people, which is isolating us from the people we love.Given the factors above, the change of communication, we have to admit, is more like a double-edged sword. Neither do we discard it nor completely rely on it. Instead, we should make reasonable use of it so as to maximize its benefits.随着科学技术发展，我们见证了我们日常生活中的各种巨大变化，其中沟通方式的变化是引人注目的。

Thousands of tomatoes, weighing over 100 metric tons in total, are dropped off on the streets, turning the whole town into a huge red mess.This tradition is believed to date back to the end of World War II when some young people decided to mock the local town council's decision by organizing a massive tomato war. Over the years, the event grew and became so popular that the organizers had to limit the number of participants for safety reasons.To take part in the Tomato fight festival, all you need is a ticket, a pair of goggles to protect your eyes from the juice and seeds, and the desire to have fun. In the one hour of tomato throwing, people experience an indescribable excitement and joy. By the end of the hour, everyone is covered in tomatopaste, making it impossible to even recognize their friends or family. After the fight, the whole town is hosed down and cleaned up so that life can continue as usual.In addition to being a popular event for locals and tourists, the Tomato fight festival also serves a purpose. All the tomatoes used in the festival are not suitable for consumption, as they are overripe or otherwise unmarketable. Instead of letting them go to waste, they are used for a completely different type of enjoyment — splattering each other with tomato pulp.While it may seem like a waste of food, the Tomato fight festival demonstrates the value of creativity and finding joy in unconventional ways. People from all over the world gather to participate in this unique event, fostering a sense of community and creating unforgettable memories.31. What do participants do in the Tomato fight festival?A) They mock the local town council.B) They throw tomatoes at each other.C) They celebrate the end of World War II.D) They compete to grow the biggest tomatoes.32. How does the Tomato fight festival affect the town of Buñol?A) It transforms the town into a red mess.B) It promotes local agriculture.C) It attracts tourists from all over the world.D) It causes serious safety concerns.33. Why did the organizers have to limit the number of participants over the years?A) To secure enough tomatoes for everyone.B) To prevent damage to public property.C) To increase the excitement and joy of the event.D) To ensure the safety of the participants.34. What is necessary for people to participate in the festival?A) A ticket, goggles, and a tomato costume.B) A ticket, goggles, and a sense of humor.C) A ticket, goggles, and martial arts skills.D) A ticket, goggles, and tourism experience.35. What does the passage suggest about the Tomato fight festival?A) It is a waste of food resources.B) It reflects the importance of tradition.C) It promotes creativity and enjoyment.D) It should be held more frequently.Passage TwoQuestions 36 to 40 are based on the following passage.Santa Fe: The Art Capital of Southwestern AmericaSanta Fe, located in the colorful state of New Mexico, is famous for its thriving art scene and rich cultural heritage.

Answer the questions by ma rking the corresponding letter on Answer Sheet 2.Evil GeniusA)A few years ago I found myself teaching a university class on evil. It was for third-year criminology students to help them contextualize theory and research within controversial current topics. It was a huge success. The debates were heated and interesting. I could see people's views change within the course of a single lecture. Over the past 13 years, as a student, lecturer and researcher, I've enjoyed discussing the science of evil with anyone willing to listen. W hat I like most is destroying the cliche（陈词滥调）of good and evil, and replacing them with scientific insight. We need a more informed way of discussing behavior that at first we cannot, or should not, begin to understand.B) Without understanding, we risk dehumanizing others, writing off human beings simply because wedon't comprehend them. We must try to understand what we have labeled evil. We tend to think evil is something that other people are. We think of ourselves as "good people", and even when we do morally wrong things, we understand the context of our decisions. With others, however, it is far easier to write them off. If their actions deviate（偏离）substantially from what we consider acceptable, we may label them evil. We need to be careful with this. Calling someone evil is often similar to saying they cannot change, and perhaps aren't even a human at all. However, when you actually go monster-hunting, and you look deeply at the people behind shocking behavior, you may be surprised.C)As a child I used to love the Scooby-Doo carto o ns. Arriving in their "Mystery Machine", the gangwould have to find a monster who was terrorizing a neighborhood. T hey would run around looking for clues and at the end unmask the bad guy. It was always a normal person in a costume. There were no monsters. Like the Scooby crew, we may find ourselves hunting for an easy fix, one word for people who do bad things. But if we take a good look, the word'evil'is insufficient—there are no simple explanations for why humans do bad things, instead there are many, and they are all marvelously different.D)Evil is typically referred to when there is deviance from social norms, formal deviance is the violationof laws, like theft, murder, and attacks, while informal deviance involves violations of social norms, like lying. Evil behavior is typically thought to embrace one or both forms. However, deviance can also describe a behavior that simply differs from the norm.E)Perhaps this is where we can find the good side of our bad side.Deviating from the norm can make usvillains（恶棍），but it can also make us heroes. A child deviates from social pressures when they stand up for another child being bullied in school. A soldier deviates when they choose not to follow orders to kill an innocent civilian. An employee in a big tech company deviates when they expose its wrongdoings.F)Creativity is also a deviation. Here, too, things are complex. Thinking creatively has given us modernmedicine, technology and modern political structures, but it has also given us poison and nuclear weapons. Great benefit and great harm can come from the same human tendency.G)In a research paper, Evil Genius, published in 2014, the behavioral scientists Francesca Gino andScott Wiltermuth wanted to examine whether people who behave unethically in one task are more creative than others on a subsequent task, even after controlling for differences in baseline creative skills. The unethical behavior they chose was dishonesty.H)Over five experiments researchers gave participants tasks in which they could cheat. In one study, theywere given血trixes（矩阵）and had to find two numbers that added up to 10. Participants were asked to self-report how well they did at the end of the study, 59% cheated by saying that they solved more matrixes than they actually had.I)After each task, the researchers measured participants'performance on the Remote Associates Test.This shows participants three words at a time that appear to be unrelated, and the person has to think of a fourth word that is associated with all of them. For example, you might get "Fox, Man, Peep", or "Dust, Cereal, Fish". In order to find the linking words ("Hole" for the first, "Bowl" for the second) you need to be creative. The more you get right, the more creative you are thought to be because you have come up with uncommon associations.J)For every one of the five studies, they found the same thing—participants who cheated in the first task did better on the creativity task. Why? Like other forms of unethical behavior, lying means breaking rules. It involves being deviant, going against the social principle that people should tell the truth.Similarly, being creative involves "thinking outside the box", deviating from expectations. They involve similar thought patterns, so stimulating one stimulates the other. Can we learn from this?Perhaps. To be more creative, we could try lying in a controlled environment. Find online logic games and cheat at them, play Scrabble（拼宇游戏）with a dictionary, or write a story about something that is untrue? Such tasks can get our brains thinking flexibly, beyond our normal comfort zone. This is nota call to become a compulsive（强迫性的）liar,but a controlled liar.K)In addition to benefits for creativity, deviance can be a good thing in other ways. Even Philip Zimbardo, the author of the Stanford prison experiment, who showed how easily we can be led to behave badly, believes that the future of deviance research may lie more in understanding extreme pro­social behavior, such as heroism. Like evil, we often view heroism as only a possibility for outliers— for people who are abnormal. But Zimbardo asks, "What if the capability to act heroically is also fundamentally ordinary and available to all of us?" Some say we should never meet our heroes, lest they disappoint us when we find out how normal they are. But this should be liberating, not disappointing. We are all capable of behaving like outliers. It's time for us to understand deviance, and realize its potential for good as well as for harm.36.A behavior that does not conform to social norms may be described as being deviant.37.Various experiments found that participants who cheated in the initial task performed better in thecreativity test.38.People may be simply considered evil if their behaviors are morally unacceptable to us.39.The research published by two scientists was intended to examine the relationship between dishonestyand creativity.40.The author's lectures sparked lively discussions in his class.41.The researchers tested the participants'creativity by asking them to play a word game.42. It is time we realized that deviance may be capable of doing both good and harm to individuals andsociety.43.The reasons for people's evil behaviors can be explained in more ways than one.44.The math task in one experiment was designed to test participants'tendency to cheat.45.So m e creative ideas have turned out to do harm to human society.Section CDirections:'I',加re are 2 passages in this section．应ch passage is followed by some questions or unfinis加d statements. For each of加m t加re are four choices marked A), B), C) and D). You should decide on t加best choice and mark t加corresponding letter on Answer Sheet 2 with a single line through the centre. Passage OneQuestions 46 to 50 are based on the following passage.Even though we are living in an age where growing old is thought of as an inevitable misery, this doctor has been changing the game for seniors over the last 25 years.It all started in 1991 when the Harvard-educated physician was transferred from working in a stressful emergency room to being the medical director of a nursing home in upstate New York. The depressing and regimented（严格管制的）environment got him thinking on what exactly could improve the residents' conditions.Even though animals in nursing homes were illegal at the time, Dr. Bill Thomas took a chance. Based on a hunch（直觉），he brought in two dogs, four cats, hens, rabbits, 100 birds, a multitude of plants, a flower garden, and a vegetable patch.The change was dramatic. There was a 50% drop in medical prescriptions along with a dramatic decrease in death rates—but most importantly, the residents were simply happier.Dr. Thomas's approach, named the Eden Alternative, has driven nursing homes to allow a more autonomous (自主的）and creative living space for their elderly. It erases the belief that growing old means growing useless. He encourages residents to think of their age as an enriching new phase of life rather than the end of it.Thomas, now a speaker and author of several books, also created small, independently-run residences with their own bedrooms and bathrooms, and he has been preaching a singular message that getting old is not a bad thing."Within six weeks, they had to send a truck around to pick up all the wheelchairs," Thomas told the Washington Post. "You know why most people in nursing homes use wheelchairs? Because the buildings are so big."The 56-year-old doctor's methods have been adopted in Australia, Japan, Canada, and America with enormous success. Last year he published Second Wind: Navigating t如Passage to a Slower, Deeper, and More Connected Life, a guide on how to shift our perspectives on aging and growth.He is currently traveling through North America performing with his guitar and his enthusiasm on his Age of Disruption Tour.46.What has Bill Thomas been doing for a quarter of a century?A)Transforming people's lifestyle.B)Honoring his Harvard education.C)Changing people's philosophy of life.D)Shifting people's perspective on aging.47.Why did Bill Thomas try something different in the nursing home?A)He wanted to make it more pleasant for seniors.B)He wanted to apply his Harvard training to practice.C)He felt it his duty to revolutionize its management.D)He felt disappointed working in the environment.48.What do we learn about Bill Thomas bringing animals and plants into the nursing home?A)He made a mess of the nursing home.B)He did something all professionals would do.C)He won instant support from the state authorities.D)He acted in violation of the state law.49.What has Bill Thomas been persistently advocating?A)Good health is not just a privilege of the young.B)Nursing homes should be strictly limited in size.C)Getting old is by no means something miserable.D)Residences for seniors should be run independently.50.How is Bill Thomas's new concept received?A)It is gaining gr o und in many countries.B)It is being heatedly debated worldwide.C)It is considered revolutionary everywhere.D)It is winning approval from the government.Passage TwoQuestions 51 to 55 are based on the following p邸吨e.Research shows that in developed countries, more affluent and educated people tend to consume higher-quality diets一including more fruits and vegetables, fish and whole grains. On the contrary, economically disadvantaged people report diets that are nutrient-poor and energy-dense. They are less likely to have food-purchasing habits that conform to public health recommendations.These dietary differences are often accompanied by higher rates of obesity and diabetes among lower­income people. This relationship between social class and diet quality and health is extensively documented. However, the research does not explain why this is the case--a question that has significant implications for designing effective policies and initiatives to improve diets and prevent chronic diseases.Public-health initiatives to promote healthy diets often focus on providing nutrition education and recipes（食谱）．These approaches, however, often presume less food literacy (i.e. food knowledge and skills) among low-income people. Are unhealthy diets really the result of poor choices, limited food skills and knowledge?Research suggests that adults in food-insecure households are just as likely as those in food-secure households to adjust recipes to make them more healthy. They are also just as proficient in food preparation and cooking skills. There is no indication that increasing food skills or budgeting skills will reduce food insecurity.Instead, disadvantaged groups are constrained by their economic, material and social circumstances. For example, low income is the strongest predictor of food insecurity in Canada, where one in eight households experiences insufficient access to nutritious foods.It's well-established that food prices are an important determinant of food choice. Low-incomehouseholds report that they find it difficult to adopt dietary guidelines because food prices are a barrier to improving their diets.When researchers estimate the cost of diets people actually eat, higher-quality diets are typically more costly.While this may be so, it does not, in itself, prove that healthy diets are necessarily more expensive or cost-prohibitive. After all, not all socioeconomically disadvantaged people consume poor diets.We can easily think of a number of f o ods and recipes that are both inexpensive and nutritious.

"You should write at least 120 words but no more than 180 words.【参考范文】Online Libraries Are Becoming Increasingly Popular With the advancement in science and technology, a growing number of citizens and college students are more likely to make use of the online libraries. As far as I am concerned, the primary causes for this phenomenon can be summarized as follows.First and foremost, the popularity of the Internet and mobile-phones provides us with such convenient tools that online libraries are available for readers in any time and any places. What’s more, libraries are where pupils, university students and citizens spend many hours in doing homework and researching for their book reports and papers. As a result, online libraries offer abundant information and latest reference materials for them to finish their tasks.As a consequence, it can be said that the quality of the libraries is second only in significance to teachers, so it is crucial for everyone to read intensively and comprehensively. Therefore, I am firmly believing that such a trend will yield positive implications to our society.这次考察的话题与我们的学习生活密切相关，因此，大家可以通过范文，有意识的积累关于图书馆与阅读话题的写作素材。

The book is called The Nightingale by Kristin Hannah.Set during World War Ⅱ, the story follows two sisters living in France who are forced to make difficult choices and sacrifices as they try to survive and resist the Nazi occupation.

三，写作要注重语法结构，不要出现明显的语法错误，否则扣分较多，影响总体成绩。

四，遇到不会写的词，要用其他相关的词语表达。

Despite having a 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 animal is highly 32 . Inside a rat's nose are up to 1,000 different types of olfactory receptors （嗅觉感受器）, whereas humans only have 100 to 200 types. This gives rats the ability to detect __33 smells.

So it may seem rather strange that I have returned to college to finish the degree I left undone some four decades ago. I am making my way through Columbia University, surrounded by students whoquickly 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 issuestake-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 midtermthe morning it was due. To say 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 did some 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,。

Imagine you are wandering about on a Thai island or 26 the ruins of Angkor. It’s hot so you grab a bottle of water from a local vendor. It’s the safe, sane thing to do, right? The bottle is27 , and the label says “pure water”, but maybe what’s inside is not so28 . Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 29 microplastics?That’s the conclusion of a recently 30 study, which analyzed 259 bottles from 11 brands sold in nine countries, 31 an average of 325 plastic particles per liter of water. These microplastics included a 32 commonly known as PET and are widely used in the manufacture of clothing and food and 33 containers. The study was conducted at the State University of New York on behalf of Orb Media, a journalism organization. About a million bottles are bought every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.Confronted with this 34 , several bottled-water manufacturers including Nestle and Coco-Cola undertook their own studies using the same methodology. These studies showed that their water did contain microplastics, but far less than the Orb study suggested. Regardless, the World Health Organization has now launched a review into the 35 health risks of drinking water from plastic bottles.Section BDirections: In this section, you are going to read a passage with ten statements attached to 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 Quiet Heroism of Mail Delivery[A] On Wednesday, a polar wind brought bitter cold to the Midwest. Overnight, Chicago reached a low of 21 degrees Fahrenheit below zero, making it slightly colder than Antarctica, Alaska, and the North Pole. Wind chills were 64 degrees below zero in Park Rapids, Minnesota, and 45 degrees below zero in Buffalo, North Dakota, according to the National Weather Service. Schools, restaurants, and businesses closed, and more than 1,000 flights have been canceled.[B] Even the United States Postal Service (USPS) suspended mail delivery temporarily. “Due to this arctic outbreak and concerns for the safety of USPS employees,” USPS announced Wednesday morning, “the Postal Service is suspending delivery Jan. 30 in the following 3-digit ZIP Code locations.” Twelve regions were listed as unsafe on Wednesday; on Thursday, eight remained.[C] As global surface temperatures increase, so does the likelihood of extreme weather. In 2018 alone, wildfires, volcanic eruptions, hurricanes, mudslides, and other natural disasters cost at least $49 billion in the United States. As my colleague V ann Newkirk reported, Puerto Rico is still confronting economic and structural destruction and resource scarcity from 2017’s Hurrican e Maria. Natural disasters can wreck a community’s infrastructure, disrupting systems for months or years. Some services, however, remind us that life will eventually return, in some form, to normal.[D] Days after the deadly 2017 wildfires in Santa Rosa, California, a drone caught footage of a USPS worker, Trevor Smith, driving through burned homes in that familiar white van, collecting mail in an affected area. Thevideo is striking: The operation is familiar, but the scene looks like the end of the world. According to Rae Ann Haight, the program manager for the national-preparedness office at USPS, Smith was fulfilling a request made by some of the home owners to pick up any mail that was left untouched. For Smith, this was just another day on the job. “I followed my route like I normally do,” Smith told a reporter. “As I’d come across a box that was up but with no house, I checked, and there was mail—outgoing mail—in it. And so we picked those up and carried on.”[E] USPS has sophisticated emergency plans for natural disasters. Across the country, 285 emergency-management teams are devoted to crisis control. These teams are trained annually using a framework known as the three Ps: people, property, product. After mail service stops due to weather, the agen cy’s top priority is ensuring that employees are safe. Then it evaluates the health of infrastructure, such as the roads that mail carriers drive on. Finally, it decides when and how to re-open operations. If the destruction is extreme, mail addressed to the area will get sent elsewhere. In response to Hurricane Katrina in 2005, USPS redirected incoming New Orleans mail to existing mail facilities in Houston. Mail that was already processed in New Orleans facilities was moved to an upper floor so it would be protected from water damage.[F] As soon as it’s safe enough to be outside, couriers start distributing accumulated mail on the still-accessible routes. USPS urges those without standing addresses to file change-of-address forms with their new location. After Hurricane Katrina hit in 2005, mail facilities were set up in dozens of other locations across the country in the two weeks that USPS was unable to provide street delivery.[G] Every day, USPS processes, on average, 493.4 million pieces of mail—anything from postcards to Social Security checks to medicine. Spokespeople from both USPS and UPS told me all mail is important. But some mail can be extremely sensitive and timely. According to data released in January 2017, 56 percent of bills are paid online, which means that just under half of payments still rely on delivery services to be completed. [H] It can be hard to identify which parcels are carrying crucial items such as Social Security checks, but USPS and UPS try their best to prioritize sensitive material. They will coordinate with the Social Security Administration to make sure that Social Security checks reach the right people in a timely fashion. After Hurricane Florence and Hurricane Michael last fall, USPS worked with state and local election boards to make sure that absentee ballots were available and received on time.[I] Mail companies are logistics companies, which puts them in a special position to help when disaster strikes. In a 2011 USPS case study, the agency emphasized its massive in frastructure as a “unique federal asset” to be called upon in a disaster or terrorist attack. “I think we’re unique as a federal agency,” USPS official MikeSwigart told me, “because we’re in literally every community in this country … We’re obligated to d eliver to that point on a daily basis.”[J] Private courier companies, which have more dollars to spend, use their expertise in logistics to help revitalize damaged areas after a disaster. For more than a decade, FedEx has supported the American Red Cross in its effort to get emergency supplies to areas affected by disasters, both domestically and internationally. In 2012, the company distributed more than 1,200 MedPacks to Medical Reserve Corps groups in California, and donated space for 3.1 million pounds of charitable shipping globally. Last October, the company pledged $1 million in cash and transportation support for Hurricanes Florence and Michael. UPS’s charitable arm, the UPS Foundation, uses the company’s logistics to help disaster-struck areas rebu ild. “We realize that as a company with people, trucks, warehouses, we needed to play a larger role,” said Eduardo Martinez, the president of the UPS Foundation. The company employs its trucks and planes to deliver food, medicine, and water. The day before I spoke to Martinez in November, he had been touring the damage from Hurricane Michael in Florida with the American Red Cross. “We have an obligation to make sure our communities are thriving, prosperous,” he said.[K] Rebuilding can take a long time, and even then, impressions of the disaster may still remain. Returning to a sense of normalcy can be difficult, but some small routines—mail delivery being one of them—may help residents remember that their communities are still their communities. “When they see that carrier back out on the street,” Swigart said, “that’s the first sign to them that life is starting to return to normal.”36. The United States Postal Service has a system to ensure its employees’ safety.37. One official says USPS is unique in that it has more direct reach to communities compared with other federal agencies38. Natural disasters can have a long-lasting impact on community life.39. Mail delivery service i$ still responsible for the completion of almost half of payments.40. The sight of a mailman on the street is a reassuring sign of life becoming normal again.41. After Hurricane Katrina interrupted routine delivery, temporary mail service points were set up.42. Postal service in some regions in the U.S. was suspended due to extreme cold weather.43. Private postal companies also support disaster relief efforts by distributing urgent supplies.44. A dedicated USPS employee was on the job carrying out duties in spite of extreme conditions.45. Postal services work hard to identify items that require priority treatment.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.Professor Ashok Goel of Georgia Tech developed an artificially intelligent teaching assistant to help handle the enormous number of student questions in the online class, Knowledge Based Artificial Intelligence. This online course is a core requirement of Georgia Tech’s online Master of Science in Computer Science program. Professor G oel already had 8 teaching assistants, but that wasn’t enough to deal with the overwhelming number of questions from students.Many students drop out of online courses because of the lack of teaching support. When students feel isolated or confused and reach out with questions that go unanswered, their motivation to continue begins to fade. Professor Goel decided to do something to remedy this situation and his solution was to create a virtual assistant named Jill Watson, which is based on the IBM Watson platform.Goel and his team developed several versions of Jill Watson before releasing her to the online forums. At first, the virtual assistant wasn’t too great. But Goel and his team sourced the online discussion forum to find all 40,000 questions that had ever been asked since the class was launched. Then they began to feed Jill the questions and answers. After some adjustment and sufficient time, Jill was able to answer the students’ questions correctly 97% of the time. The virtual assistant became so advanced and realistic that the students didn’t know she was a computer. The students, who were studying artificial intelligence, were interacting with artificial intelligence and couldn’t tell it apart from a real human being. Goel didn’t inform them about Jill’s true identity until April 26. The students were actually very positive about the experience.The goal of Professor Goel’s virtual assistant next year is to take over answering 40% of all questions posed by students on the online forum. The name, Jill Watson, will of course, change to something else next semester. Professor Goel has a much rosier outlook on the future of AI than say, Elon Musk, Stephen Hawking, Bill Gates or Steve Wozniak.46. What do we learn about Knowledge-Based Artificial Intelligence?A) It is a robot that can answer students’ questions.B) It is a course designed for students to learn online.C) It is a high-tech device that revolutionizes teaching.D) It is a computer program that aids student learning.47. What problem did Professor Goel meet with?A) His students were unsatisfied with the assistants.B) His course was too difficult for the students.C) Students’ questions were too many to handle.D) Too many students dropped out of his course.48. What do we learn about Jill Watson?A) She turned out to be a great success. B) She got along pretty well with students.C) She was unwelcome to students at first. D) She was released online as an experiment.49. How did the students feel about Jill Watson?A) They thought she was a bit too artificial. B) They found her not as capable as expected.C) They could not but admire her knowledge. D) They could not tell her from a real person.50. What does Professor Goel plan to do next with Jill Watson?A) Launch different versions of her online.B) Feed her with new questions and answers.C) Assign her to answer more of students’ questions.D) Encourage students to interact with her more freely.Passage TwoQuestions 51 to 55 are based on the following passage.Thinking small, being enga ging, and having a sense of humor don’t hurt. Those are a few of the traits of successful science crowdfunding efforts that emerge from a recent study that examined nearly 400 campaigns. But having a large network and some promotional skills may be more crucial.Crowdfunding, raising money for a project through online appeals, has taken off in recent years for everything from making movies to building water-saving gadgets. Scientists have tried to tap Internet donors, too, with mixed success. Some raised more than twice their goal, but others have fallen short of reaching more modest targets.To determine what separates science crowdfunding triumphs from failures, a team led by science communications scholar Mike Schäfer of the University of Zurich in Switzerland examined the content of the WebPages for 371 recent campaigns.Four traits stood out for those that achieved their goals, the researchers report in Public Understanding of Science. For one, they use a crowdfunding platform that specializes in raising money for science, and not just any kind of project. Although sites like Kickstarter take all comers, platforms such as , , and only present scientific projects. For another, they present the project with a funny video because good visuals and a sense of humor improved success. Most of them engage with potential donors since projects that answered questions from interested donors and posted lab notes fared better. And they target a small amount of money. The projects included in the study raised $4000 on average, with 30% of projects receiving less than $1000. The more money a project sought, the lower the chance it reached its goal, the researchers found.Other factors may also significantly influence a project’s s uccess, m ost notably, the size of a scientist’s personal and professional networks, and how much a researcher promotes a project on his or her own. Those two factors are by far more critical than the content on the page. Crowdfunding can be part of researc hers’ efforts to reach the public, and people give because “they feel a connection to the person” who is doing the fundraising—not necessarily to the science.51. What do we learn about the scientists trying to raise money online for their projects?A) They did not raise much due to modest targets.B) They made use of mixed fundraising strategies.C) Not all of them achieved their anticipated goals.D) Most of them put movies online for the purpose.52. What is the purpose of Mike Schäfer’s research of recent crowdfunding campaigns?A) To create attractive content for science websites.B) To identify reasons for their different outcomes.C) To help scientists to launch innovative projects.D) To separate science projects from general ones.53. What trait contributes to the success of a crowdfunding campaign?A) The potential benefit to future generations. B) Its interaction with prospective donors.C) Its originality in addressing financial issues. D) The value of the proposed project.54. What did the researchers think of the financial targets of crowdfunding projects?A) They should be small to be successful. B) They should be based on actual needs.C) They should be assessed with great care. D) They should be ambitious to gain notice.55. What motivates people to donate in a crowdfunding campaign?A) The ease of access to the content of the webpage.B) Their desire to contribute to the cause of science.C) The significance and influence of the project itself.D) Their feeling of connection to the scientists themselves.Part ⅣTranslation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

So, any disruption to the world's factories 26 . And that disruption is surely coming. Factories are being digitised, filled with new sensors and new computers to make them quicker, more 27 and more efficient.Robots are breaking free from the cages that surround them, learning new skills and new ways of working. And 3D printers have long 28 a world where you can make anything; anywhere, from a computerised design. That vision is 29 closer to reality. These forces will lead to cleaner factories, producing better goods at lower prices, personalised to our individual needs and desires. Humans will be 30 many of the dirty, repetitive, and dangerous jobs that have long been a 31 of factory life.Greater efficiency 32 means fewer people can do the same work. Yet factory bosses in many developed countries are worried about a lack of skilled human workers-and see 33 and robots as a solution. But economist Helena Leurent says this period of rapid change in manufacturing is a 34 opportunity to make the world a better place. "Manufacturing is the one system where you have got the biggest source of innovation, the biggest source of economic growth, and the biggest source of great jobs in the past. You can see it changing. That's an opportunity to 35 that system differently, and if we can, it will have tremendous significance.

Each paragraph is marked with a letter：Answer the questions bymarking the corresponding letter on Answer Sheet 2.The History of the Lunch BoxA) It was made of shiny, bright pink plastic with a Little Mermaid sticker on the front, and Icarried it with me nearly every single day. My lunch box was one of my first prized possessions, a proud statement to everyone in my kindergarten; "I love Mermaid-Ariel on my lunch box"B) That bulky container served me well through my first and second grades, until the live-actionversion of 101 Dalmatians hit theaters, and I needed the newest red plastic box with characters like Pongo and Perdita on the front. I know I'm not alone here-I bet you loved your first lunch box, too.C) Lunch boxes have been connecting kids to cartoons and TV shows and super-heroes fordecades. But it wasn't always that way. Once upon a time, they weren't even boxes. As schools have changed in the past century, the midday meal container has evolved right along with them.D) Let's start back at the beginning of the 20th century-the beginning of the lunch box story,really. While there were neighborhood schools in cities and suburbs, one-room schoolhouses were common in rural areas. As grandparents have been saying for generations, kids would travel miles to school in the countryside (often on foot.)E) "You had kids in rural areas who couldn't go home from school for lunch, so bringing yourlunch wrapped in a cloth, in oiled paper, in a little wooden box or something like that was a very long-standing rural tradition," says Paula Johnson, head of food history section at the Smithsonian National Museum of American History in Washington, D. C.F) City kids, on the other hand, went home for lunch and came back. Since they rarely carried ameal, the few metal lunch buckets on the market were mainly for tradesmen and factory workers.G) After World War I, a bunch of changes reshaped schools-and lunches. More women joined theworkforce. Small schools consolidated into larger ones, meaning more students were farther away from home.' And the National School Lunch Act in 1946 made cafeterias much more common. Still, there wasn't much of a market for lunch containers-yet. Students who carried their lunch often did so in a re-purposed bucket or tin of some kind.H) And then everything changed in the year of 1950. You might as well call it the Year of theLunch Box, thanks in large part to a genius move by a Nashville-based manufacturer, Aladdin Industries. The company already made square metal meal containers, the kind workers carried, and some had started to show up in the hands of school kids.I) But these containers were really durable, lasting years on end. That was great for theconsumer, not so much for the manufacturer. So executives at Aladdin hit on an idea that would harness the newfound popularity of television. They covered lunch boxes with striking red paint and added a picture of TV and radio cowboy Hopalong Cassidy on the front.J) The company sold 600,000 units the first year. It was a major "Ah-ha!" moment, and a wave of other manufacturers jumped on board to capitalize on new TV shows and movies."ThePartridge Family, the Addams Family, the Six Million Dollar Man, the Bionic Woman-everything that was on television ended up on a lunch box,"says Allen Woodall. He's the founder of the Lunch Box Museum in Columbus, Georgia."It was a great marketing tool because kids were taking that TV show to school with them, and then when they got home they had them captured back on TV," he says.K) And yes, you read that right: There is a hunch box museum, right near the Chattahoochee River, Woodall has more than 2,000 items on display. His favorite? The Green Hornet lunch box, because he used to listen to the radio show back in the 1940s.L）The new trend was also a great example of planned obsolescence, that is, to design a product so that it will soon become unfashionable or impossible to use and will need replacing. Kids would beg for a new lunch box every year to keep up with the newest characters, even if their old lunch box was perfectly usable.M) The metal lunch box craze lasted until the mid-1980s，when plastic took over. Two theories exist as to why. The first-and most likely-is that plastic had simply become cheaper. The second theory possibly an urban myth-is that concerned parents in several states proposed bans on metal lunch boxes, claiming kids were using them as "weapons" to hit one another.There's a lot on the internet about a state-wide ban in Florida, but a few days worth of digging by a historian at the Florida State Historical Society found no such legislation. Either way, the metal lunch box was out.N) The last few decades have brought a new lunch box revolution, of sorts. Plastic boxes changed to lined cloth sacks, and eventually, globalism brought tiffin containers from India and bento boxes from Japan. Even the old metal lunch boxes have regained popularity."I don't think the heyday（盛时期）has passed," says D.J.Jayasekara, owner and founder of , a retailer in Pasadena, California. "I think it has evolved. The days of the ready-made, 'you stick it in a lunch box and carry it to school' are kind of done. "O) The introduction of backpacks changed the hunch box scene a bit, he adds. Once kids started carrying book bags, that bulky traditional hunch box was hard to fit inside. "But you can't just throw a sandwich in a backpack," Jayasekara says. "It still has to go into a container."That is, in part, why smaller and softer containers have taken off-they fit into backpacks.P) And don't worry-whether it's a plastic bento box or a cloth bag, lunch containers can still easily be covered with popular culture. "We keep pace with the movie industries so we can predict which characters are going to be popular for the coming months," Jayasekara says."You know, kids are kids."36. Lunch containers were not necessary for school kids in cities.37. Putting TV characters on lunch boxes proved an effective marketing strategy.38. Smaller hunch boxes are preferred because they fit easily into backpacks.39. Lunch boxes have evolved along with the transformation of schools.40. Around the beginning of the nineteen fifties, some school kids started to use metal mealcontainers.41. School kids are eager to get a new lunch box every year to stay in fashion.42. Rural kids used to walk a long way to school in the old days.43. The author was proud of using a hunch box in her childhood.44. The most probable reason for the popularity of plastic hunch boxes is that they are lessexpensive.45. The durability of metal meal containers benefited consumers.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 AnswerSheet 2 with a single line through the centre.Passage OneQuestions 46 and 50 are based on the following passage.A growing number of U. S. bike riders are attracted to electric bikes for convenience, health benefits and their fun factor. Although ebikes first appeared in the 90s, cheaper options and longer-lasting batteries are breathing new life into the concept.Established bike companies and startups are embracing ebikes to meet demand. About 34 million ebikes were sold worldwide last year, according to data from eCycleElectric Consultants. Most were sold in Europe and China, where the bikes already have exploded in popularity. Recently, the U. S. market has grown to 263,000 bikes, a 25% gain from the prior year.The industry is benefiting from improved batteries as suppliers over the years developed technology for laptops, smartphones and electric cars. In 2004, the price of batteries used on ebikes fell, spurring European sales.But lower cost options are emerging, too. This month, three U. S. bikeshare companies, Motivate, LimeBike and Spin, announced electric bicycles will be added to their fleets. New York-based Jump Bikes is already operating an electric bikeshare in Washington, D. C., and is launching in San Francisco Thursday. Rides cost $ 2 for 30 minutes.The system works like existing dockless bikeshare systems, where riders unlock bikes through a smartphone app. "This is the beginning of a long-term shift away from regular pedal (踏板) to electric bikes," said Jump Bikes CEO Ryan Rzepecki. "When people first jump on an ebike, their face lights up. It's exciting and joyful in a way that you don't get from a regular bike."Two years ago, CEO Chris Cocalis of Pivot Cycles, which sells high-end mountain bikes, found that U. S. bike shops weren't interested in stocking ebikes. Some retailers warned Cocalis that they'd drop the brand if it came out with an electric bike.Now that sales are taking off, the vast majority of bike dealers are asking Cocalis when he' Il make an ebike available. "There's tremendous opportunity to get a generation of people for whom suffering isn't their thing," Cocalis said. "Ebike riders get the enjoyable part of cycling without the massive suffering of climbing huge hills."46. What do we learn from the passage about ebikes?A. Their health benefits and fun values outweigh their cost.B. They did not catch public attention in the United States until the 1990s.C. They did not become popular until the emergence of improved batteries.D. Their widespread use is attributable to people's environmental awareness.47. What brought about the boost in ebike sales in Europe at the beginning of the century?A. Updated technology of bike manufacture.B. The falling prices of ebike batteries.C. Changed fashion in short-distance travel.D. The rising costs for making electric cars.48. What is the prospect of the bike industry according to Ryan Rzepecki?A. More will be invested in bike battery research.B. The sales of ebikes will increase.C. It will profit from ebike sharing.D. It will make a difference in people's daily lives.49. What prevented Chris Cocalis from developing ebikes sooner?A. Retailers' refusal to deal in ebikes.B. High profits from conventional bikes.C. Users' concern about risks of ebike riding.D. His focus on selling costly mountain bikes.50. What makes Chris Cocalis believe there is a greater opportunity for ebike sales?A. The further lowering of ebike prices.B. The public's concern for their health.C. The increasing interest in mountain climbing.D. The younger generation's pursuit of comfortable riding.Passage TwoQuestions 51 to 55 are based on the following passage.The terms "global warming" and "climate change" are used by many, seemingly interchangeably. But do they really mean the same thing?Scientists shaped the history of the terms while attempting to accurately describe how humans continue to alter the planet. Later, political strategists adopted the terms to influence public opinion.In 1975, geochemist Wallace Broecker introduced the term "climate change" in an article published by Science. In 1979，a National Academy of Sciences report used the term "global warming" to define increases in the Earth's average surface temperature, while "climate change" more broadly referred to the numerous effects of this increase，such as sea-level rise and ocean acidification（酸化）.During the following decades，some industrialists and politicians launched a campaign to sow doubt in the minds of the American public about the ability of fossil-fuel use, deforestation and other human activities to influence the planet's climate.Word use played a critical role in developing that doubt. For example，the language and polls expert Frank Luntz's wrote a memo encouraging the use of "climate change" because the phrase sounded less scary than "global warming," reported the Guardian.However, Luntz's recommendation wasn't necessary. A Google Ngram Viewer chart showsthat by 1993 climate change was already more commonly used in books than global warming. By the end of the next decade both words were used more frequently，and climate change was used nearly twice as often as global warming.NASA used the term "climate change" because it more accurately reflects the wide range of changes to the planet caused by increasing amounts of greenhouse gases in the atmosphere.The debate isn't new. A century ago，chemist Svante Arrhenius started one of the first debates over the potential for humans to influence the planet's climate. Arrhenius calculated the capability of carbon dioxide to trap heat in the Earth's atmosphere, but other chemists disagreed. Some argued that humans weren't producing enough greenhouse gases, while others claimed the effects would be tiny. Now, of course, we know that whatever you call it, human behavior is warming the planet, with grave consequences ahead.51. Why did politicians use the two terms "global warming" and "climate change"?A. To sway public opinion of the impact of human activities on Earth.B. To more accurately describe the consequences of human activities.C. To win more popular votes in their campaign activities.D. To assure the public of the safety of existing industries.52. As used in a National Academy of Sciences report, the term "climate change" differs from "global warming" in that .A. it sounds less vague.B. it looks more scientific.C. it covers more phenomena.D. it is much closer to reality.53. What did industrialists of the late 20th century resort to in order to mislead Americans?A. Made-up survey results.B. Hired climate experts.C. False research findings.D. Deliberate choice of words.54. Why did NASA choose the term "climate change"?A. To obtain more funds.B. For greater precision.C. For political needs.D. To avoid debate.55. What is the author's final conclusion?A. Global warming is the more accurate term.B. Accuracy of terminology matters in science.C. Human activities have serious effects on Earth.D. Politics interferes with serious scientific debate.Part IV Translation（30 minutes）Directions：For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
