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. Effective time management helps individuals to prioritize tasks, handle multiple responsibilities, and increase productivity. It allows individuals to make the most out of their time and achieve their goals efficiently.Here are some tips for effective time management:1.Set goals: Identify your long-term and short-termgoals.

This will help you maintain focus and preventburnout.7.Avoid procrastination: Procrastination can lead tounnecessary stress and missed deadlines.

It also promotes weight loss and helps to maintain a healthy body weight. Regular exercise reduces the risk of chronic diseases such as heart disease, diabetes, andcertain types of cancer. It can also improve mental health by reducing symptoms of depression and anxiety.In addition to the physical benefits, exercise is also important for cognitive function.

Part III Reading Comprehension(40 minutes) Section ADirections:In this section, there is a passage with ten blanks. 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 identiﬁ ed 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.The sheets are damp with sweat. You’re cold, but your heart is racing as if a killer just chased you down a dark street.

Doctors 31 don’t consider occasional nightmares a problem. They can just be symptoms of a sleep disorder that can 32 from an unpleasant experience, stress, or certain drugs.To treat the disorder, there are a number of medicines and therapies that are backed by 33 research, according to the American Academy of Sleep Medicine, which analyzed the available research on the treatment of nightmare disorder in a recent 34 published in the Journal of Clinical Sleep Medicine.However, nightmares are complicated, and researchers are still struggling to understand them, said Dr. Rachel Salas, an expert on sleep disorders and an associate professor at Johns Hopkins Medicine in Baltimore.

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.Why it matters that teens are reading lessA)Most of us spend much more time with digital media than we did a decade ago. But today’s teens have grownup with smartphones. Compared with teens a couple of decades ago, the way they interact with traditional media like books and movies is fundamentally diﬀ erent.B) Analysis of surveys of over one million teens in the United States collected since 1976 reveals a major shift inhow teens are spending their leisure time. Paper books are being ignored, in favor of screens. Digital devices are changing other behaviors, too. More and more, young people choose spending time on their electronic devices over engaging in other activities, regardless of the type. Indeed, by 2016, the average American high school senior said they spent six hours a day writing text messages, on social media, and online during their free time. And that covers just three activities, and if other digital media activities were included, that estimate would no doubt rise.C)Teens did not always spend that much time with digital media. Online time has doubled since 2006, andsocial media use has moved from a periodic activity to a daily one in the same period. By 2016, nearly nine out of ten young women in the 12th grade said they visited social media sites every day. Meanwhile, time spent playing video games rose from under an hour a day to an hour and a half on average. One out of ten American 8th grade students in 2016 spent 40 hours a week or more playing video games. Let me emphasize that this is equal to the time most adults spend per week at work.D)If teens are spending so much time using electronic devices, does that mean they have to give up some otheractivities? Maybe not. Over the years, many scholars have insisted that time online does not necessarily take away time spent engaging with traditional media or on other activities. Some people, they argue, are just more interested in certain kinds of media and entertainment. Thus, using more of one type of media does not necessarily mean less of the other.E)That may be true, but that still does not tell us much about what happens across a whole generation of peoplewhen time spent on digital media grows. Large surveys conducted over the course of many years tells us that American youth are not going to the cinema nearly as often as they did in the past. While 70 percent of 8th and 10th grade students used to go to the movies once a month or more, now only about half do this.More and more, watching a movie is something teens choose to do on their electronic devices. Why is thisa problem? One reason is that going to the cinema is generally a social activity. Now, watching movies issomething that most teens do alone. This fits a larger pattern. In another analysis, researchers found that today’s teens go out with their friends much less often than previous generations did.F)But the trends related to movies are less disturbing compared with the change in how teens spend their time.Research has revealed an enormous decline in reading. In 1980, about 60 percent of senior high school students said they read a book, newspaper or magazine every day that was not assigned for school. By 2016, only 16 percent did. This is a huge drop and it is important to note that this was not merely a decline in reading paper books, newspapers or magazines. The survey allowed for reading materials on a digital device.G)Indeed, the number of senior high school students who said they had not read any books for pleasure in thelast year was one out of three by 2016. That is triple the number from two decades ago. For today’s youth, books, newspapers and magazines have less and less of a presence in their daily lives. Of course, teens are still reading. But they are generally reading short texts. Most of them are not reading long articles or books that explore deep themes and require critical thinking and reﬂ ection. Perhaps not accidentally, in 2016 reading scores were the lowest they have ever been since 1972.H)This might present problems for young people later on. When high school students go on to college, theirpast and current reading habits will inﬂ uence their academic performance. Imagine going from reading texts as short as one or two sentences to trying to read entire books written in complex language and containing sophisticated ideas. Reading and comprehending longer books and chapters takes practice, and American teens are no longer getting that practice.I)So how can this problem be solved? Should parents and teachers take away teens’ smartphones and replacethem with paper books? Probably not. Research has shown that smartphones are currently American teens’ main form of social communication. This means that, without a smartphone, teens are likely to feel isolated from their peers. However, that does not mean teens need to use electronic devices as often as they do now.Data connecting excessive digital media time to mental health issues suggests a limit of two hours a day of free time spent with screens, a restriction that will also allow time for other activities—like going to the movies with friends or reading longer, more complicated texts.J)The latter is especially important. I would argue that of all the changes brought about by the widespread use of digital devices, the huge decline in reading is likely to have the biggest negative impact on today’s teens because reading books and longer articles is one of the best ways to learn critical thinking. It helps people to understand complex issues and to separate fact from ﬁ ction. Thus, deep reading is crucial for being a good citizen, a successful college student and a productive employee. If serious reading dies, a lot will go with it.36. Many years’ surveys reveal that young people in America are going to the cinema much less often than theyused to.37. Survey analysis shows American teens now spend their leisure time on digital devices rather than readingprinted books.38. The number of senior high schoolers not reading books for pleasure in a year increased three times over 20years.39. Many scholars claim that spending time on electronic devices doesn’t necessarily mean a decrease of time forother activities.40. Most people spend much more time interacting with digital media than they did ten years ago.41. The author claims that it will be a great loss if we no longer read books and longer articles.42. Over a decade or so, American teens’ social media use shifted from an occasional activity to a routine one.43. A more disturbing trend in America today is that teens are spending far less time reading than around fourdecades ago.44. Some ﬁ ve years ago, high school seniors in America generally spent more than six hours a day on electronicdevices.45. It was found that American youngsters today don’t socialize nearly as much as the earlier generations.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.Have you ever wondered how acceptable it is to hug or touch someone? While it may sound safe to avoid all physical contact so as not to oﬀ end anyone, the lack of touching might imply cold attitudes or indiﬀ erence in interpersonal relationships.So, what should we do? The simple answer is to thoroughly learn unique cultural norms for physical contact. In nonverbal communication terminology (术语)，physical contact and the study of touching are generally referred to as haptics.Haptics in communication often suggest the level of intimacy. They are usually classiﬁ ed into two groups: high-contact and low-contact.Asia and quite surprisingly the United States, Canada and Britain belong to low-contact cultures. People from the rest of the world, such as Latin America, are considered to be in high-contact cultures, where they tend to expect touching in social interactions and feel more comfortable with physical closeness. Despite the classiﬁ cation, there are more complex factors such as relational closeness, gender, age, and context that can aﬀ ect how someone views physical contact.One common French custom of greetings is cheek-kissing, but it is mostly restricted to friends, close acquaintances and family members. While cheek-kissing for Latin Americans is also a universal greeting form, it does not require such a high degree of relational closeness. However, gender matters more for them because cheek-kissing often only happens between women or a man and a woman but not two men.In contrast, in certain Arabian, African, and Asian countries, men can publicly hold hands or show physical affection as signs of brotherhood or friendship while these behaviors may suggest a romantic relationship in other parts of the world. Although men’s touching is more normal in these cultures, physical contact between persons of opposite sexes who are not family members is negatively perceived in Arabian countries.These factors could definitely affect the degree to which someone is comfortable with tactile(触觉的) communication and physical intimacy. Therefore, if you are someone who loves to show physical aﬀ ection, you should not be afraid to show it or drastically change your behaviors—just ask for consent beforehand!46. What does the author say in the ﬁ rst paragraph about physical contact?A)Its role in interpersonal relationships is getting increasingly important.B)It is becoming more acceptable to many who used to think it oﬀ ensive.C)Its absence might suggest a lack of warmth in interpersonal relationships.D)It might prompt diﬀ erent responses from people of diﬀ erent social backgrounds.47. What does physical contact in communication suggest?A)What social class people belong to.C)What family background people come from.B)How civilized the communicators are.D)How close the communicators’ relationships are.48. What do we learn about p eople in high-contact cultures?A)They are sensitive to the way people express their emotions.B)They take touching as a cultural norm in social interactions.C)They attach great importance to close ties among people.D)They tend to be more open in interpersonal relationships.49. What do we learn about social customs in Arabian countries?A)Men can show friendship in public through physical aﬀ ection.B)Non-traditional romantic relationships are simply unacceptable.C)Physical contact between unfamiliar people is negatively perceived.D)People of diﬀ erent ages and genders show aﬀ ection in diﬀ erent ways.50. What does the author tell us to do concerning tactile communication?A)Lay emphasis on nonverbal communication.C)Pay attention to the diﬀ erences between genders.B)Learn to use appropriate body language ﬁ rst.D)Take other people’s preference into consideration. Passage TwoQuestions 51 to 55 are based on the following passage.From climate change to the ongoing pandemic (大流行病) and beyond, the issues facing today’s world are increasingly complex and dynamic. Yet solving problems like these requires new approaches that extend beyond traditional ways of thinking. A study led by Yale Professor of Psychology, Paul O’Keefe, found that having a growth mindset (思维倾向) of interest may spark this type of innovation.Professor O’Keefe established in earlier studies that people hold diﬀ erent beliefs about the nature of interest. Those with a growth mindset of interest tend to believe that interests can be developed and cultivated, while those with a ﬁ xed mindset of interest tend to believe that interests are inherent (与生俱有的) and simply need to be ‘found.’ Building on these ﬁ ndings, the latest research examined how a growth mindset of interest can boost integrative thinking across the traditional disciplinary boundaries of arts and sciences.For example, in one task, research participants were instructed to create new college majors by combining two or more existing academic Arts or Science programs at their university. After coding and analyzing the ideas they generated, the team found that people with a growth mindset of interest were more likely to bridge programs across the arts and sciences to create new majors like computational economics rather than creating majors that drew from only one of those areas, like computational chemistry.As Professor O’Keefe pointed out, “This research provides a useful direction for organizations whose products and services call for integrated and creative solutions. Take smartphones for example. You need not only computer science and engineering knowledge, but also an understanding of psychology and visual design to create a better product. Employees with a growth mindset may be more likely to devise innovative ideas that bridge multiple areas of knowledge to achieve better solutions. ”The beneﬁ ts of a growth mindset of interest may also extend to those seeking employment. This is a pressing issue because many people are becoming unemployed due to the COVID-19 pandemic. Having a growth mindset of interest can help job seekers expand their interests and become more adaptable to diﬀ erent ﬁ elds, and take the initiative to learn new skills.51. What does the author say about the world today?A)It faces problems that are getting more varied and complicated.B)It has done away with many of the traditional ways of thinking.C)It is undergoing radical and profound changes.D)It is witnessing various types of innovations.52. What did Professor O’Keefe ﬁ nd in his earlier studies?A)People’s interests tend to change with age.C)People are divided about the nature of interest.B)People’s interests determine their mindsets.D)People of diﬀ erent ages have diﬀ erent mindsets.53. What is the focus of Professor O’Keefe’s recent research?A)How boundaries can be removed between arts and science disciplines.B)How feasible it is to create new disciplines like computational economics.C)How students in arts and sciences view the two types of mindset of interest.D)How a growth mindset of interest can contribute to cross-disciplinary thinking.54. What does the author want to illustrate with the example of smartphones?A)Hi-tech products are needed in interdisciplinary research.B)Improved technology gives birth to highly popular products.C)Making innovative products needs multidisciplinary knowledge.D)Hi-tech products can boost people’s integrative thinking.55. What is the author’s suggestion to those who are seeking employment?A)Learning practical skills.C)Staying safe in the pandemic.B)Broadening their interests.D)Knowing their pressing issues.Part IV Translation (30 minutes) Directions:For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

The Public Utility Regulatory Policies Act of 1978 encouraged more electricity generation by allowing institutions to sell 30 power to utilities.But EIA noted many coal-fired universities have signed onto the American College and University Presidents Climate Commitment, which was launched in 2007.About 665 schools are part of the program, which aims to 31 greenhouse gas emissions. Thirty percent of the participants have pledged to be carbon 32 within 20years.The Sierra Club’s Beyond Coal campaign, which also leads campaigns for universities to withdraw their 33 in coal and other fossil fuels, lists 22 schools that have pledged to move “beyond coal,” includi ngClemson University, Indiana University, Ohio University, Penn State University, the University of Louisville and the University of Tennessee, Knoxville.The largest coal use 34 at colleges were in Michigan, Missouri, Tennessee and Indiana.

Igor Stravinsky was introducing hisrevolutionary “Rite of Spring” ballet to the world, with its discordant melodies and unorthodox choreography (编舞), and the purists in the crowd expressed their disapproval loud and clear. It might have been classical music’s version of the time Bob Dylan went electric at the Newport Folk Festival. “The noise, fighting, and shouting in the audience got so loud,” NPR’s music reporter Miles Hoffff man said of the Stravinsky debut, “that the choreographer had to shout out the numbers to the dancers so that they knew what they were supposed to do.”B) It’s difficult to imagine a similar disturbance occurring today within America’s sacredsymphony halls. In fact, it’s hard to picture any kind of disruptive activity at all (unless someone’s cell phone happens to go off and then you’d better watch your back). A mannerly aura (氛围) hangs over most classical proceedings, and many of the genre’s biggest supporters would have it no other way.C) Today, Western audiences for classical music and opera and ballet are almost always welldressed, older, respectful, achingly silent and often very wealthy (one has to be able to afford most tickets). But as many of America’s most storied “highbrow” ( 高雅的)institutions struggle financially—the Philadelphia Orchestra’s much-publicized rebound from bankruptcy is just one recent example—classical music fans and theorists are wondering how the medium can weave itself into the 21st century’s cultural fabric without sacrificing its integrity.D) For example, should we feel OK “clapping” during classical music events, even if nobodyelse is? Why shouldn’t we cheer for something great, like we do at a rock concert? The Hu f ington Post recently ran a Great Debate on this issue and many commenters came out on the side of silence. “There is no more rewarding experience in life than being part of an audience where everybody is leaning forward in silence, thoroughly carried away by a great performance of a masterpiece,”one commenter wrote. “Why is it so difficult for folks to develop an appreciation and understanding for the mannerisms and traditions of classical music?” asked another.E) The truth is that classical music audiences weren’t always so polite. Robert Greenberg, anaward-winning composer, said that when Beethoven first performed his 7th Symphony, audiences forced the orchestra to perform encores ( 重演) of certain movements immediately, applauding wildly. And in the last few decades, he said, many audiences at opera performances have abandoned pretenses, yelling “Bravo” when they feel lik e it.F) “I don’t think there’s anything wrong with an audience showing their enthusiasm for aproper moment by applauding, showing their joy,” Greenberg said, noting that the stuffiness in concert halls is “one aspect of contemporary concert etiquette”he doesn’t understand. “Instead of waiting half an hour to show enthusiasm, why not show it every eight or nine minutes?”G) Until the rules about behavior and clothing change, it’s hard to imagine multitudes ofyoung people filling concert halls on their own accord. They’re probably more likely to head to Central Park to watch a free performance with a bottle of wine and their friends.“I think anyone should be able to come into a performance dressed any way they like, and be comfortable any way they like, sitting in that seat ready to enjoy themselves,”Greenberg said. “Because it’s enjoyable.”H) Greenberg stressed that he doesn’t want people to start respecting the music less, and he’snot suggesting that we “dumb down” the experience. Rather, it’s about opening up “access.” When operas first instituted subtitles (字幕) during shows, he said, many purists didn’t like the idea, believing that the audience should instead study the works before attending. But now it’s commonplace to find titles on the seatback in front of you—choose a language, sit back, and understand what’s going on.I) Allison Vulgamore, president of the Philadelphia Orchestra, is certainly looking to thefuture. She says certain “classics concerts” dedicated to the old masters will always exist, but not every program has to feature Beethoven and Brahms—or even a stage and seats.“We’re trying to introduce different kinds of concerts in different ways,”she said. “We are an interactive society now, where people like to learn.”J) As the Philadelphia Orchestra rebounds from its financial straits, it is also aiming to experiment, without alienating the loyalists. Vulgamore pointed to Cirque de la Symphonie, a recent offering in which jugglers (玩杂耍的人) and acrobats (杂技演员) interacted with musicians. An upcoming collaboration with New York City’s RidgeTheatre, meanwhile, will feature a “suspended dance installation”and other theatrical elements occurring in conjunction with an orchestral piece.K) The orchestra also continues to offer $25 annual memberships to Philadelphia students, who can buy rush tickets to every concert on the schedule. “Students line up for the concerts they want, and we get roughly 300 or 350 kids a night coming to these. They take any of the open seats available, 5 minutes before the concert starts,” Vulgamore said. “It’s like the running of the bulls, that energy when the doors open.”L) Greenberg thinks that youthful energy needs to be harvested. Conductors don’t have to be arrogant and untouchable—they can be accessible. Perhaps there could even be a “bit of humor”about them, he suggested, and an abandoning of pretension within the high-art institutions themselves. “On one hand, these organizations are all saying the same thing: we want more general audiences, to break down cultural barriers,” he said. “But then they come up with some very snooty (目中无人的) thing that makes you crazy.”M) John Terauds, a critic who has covered Toronto’s classical music scene extensively, also wants to do away with the stuffiness. He suggested that the warmer an audience is, the better the musicians themselves will respond. “But the producer or organizer has to let everyone know it’s OK,” he said. “It’s OK to enjoy y ourself.” At the Toronto Symphony Orchestra, for example, conductor Peter Oundjian often stops between pieces, taking a moment to talk about the composer or the music in a very amiable way. And some nights, Terauds said, “at least a third”of the audience consists of students who have purchased cheaper tickets. On these nights, the energy of the room drastically shifts. It becomes a less intimidating place.N) Back in February, Terauds wrote on his blog about how going to classical performances can be intimidating. Certain people “think they have to dress up,” he wrote. “They think they have to know something about the music before they go. And, I’m sure, sitting in a seat, trembling in fear that this might be the wrong time to applaud, is also one of the factors.”O) Everyone in the classical world agrees on the need for increased “accessibility,”but achieving it is often easier said than done. Nowadays, there are unknown, unorthodox opera singers wowing (博得……的喝彩) viewers on TV programs like “America’s Got Talent”and “The Voice”. What can higher institutions do with any of that? And if they appeal to these outlets, do they risk compromising the integrity or the intelligence of the music?P) Vulgamore seems to understand this. She thinks an organization can have it both ways, claiming the new while keeping the old. And as she reorganizes the Philadelphia Orchestra, she will attempt to do just that. “The world’s most respected musicians brought together as an orchestra will always exist,” she said. “Bu t it’s essential that we be willing to experiment and fail.”36. It was not a rare occurrence that audiences behaved wildly while listening to classical music.37. Some high-art institutions don’t actually mean it when they say they want more general audiences.38. The theatre was in chaos when an unconventional ballet was first put on stage in the capital of France.39. According to one critic, the audience’s warm response would encourage the musicians to do a better job.40. Many commenters argued for the audience enjoying classical music quietly.41. What appears on the seatback screen makes it unnecessary for the audience to study the works beforehand.42. It is generally accepted that there should be no disturbance from the audience during classical music performance.43. Higher institutions will be concerned about compromising the integrity of classical music if they have to resort to the television medium.44. Heavily discounted rush tickets help attract many young students to attend classical concerts.45. The formalities of high-art theatres can intimidate some people attending a performance.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.How can one person enjoy good health, while another person looks old before her time? Humans have been asking this question for thousands of years, and recently, it’s becoming clearer and clearer to scientists that the differences between people’s rates of aging lie in the complex interactions among genes, social relationships, environments and lifestyles. Even though you were born with a particular set of genes, the way you live can influence how they express themselves. Some lifestyle factors may even turn genes on or shut them off.Deep within the genetic heart of all our cells are telomeres, or repeating segments of noncoding DNA that live at the ends of the chromosomes ( 染色体). They form caps at the ends of the chromosomes and keep the genetic material together. Shortening with each cell division, they help determine how fast a cell ages. When they become too short, the cell stops dividing altogether. This isn’t the only reason a cell can age—there are other stresses on cells we don’t yet understand very well—but short telomeres are one of the major reasons human cells grow old. We’ve devoted most of our careers to studying telomeres, and one extraordinary discovery from our labs is that telomeres can actually lengthen.Scientists have learned that several thought patterns appear to be unhealthy for telomeres, and one of them is cynical hostility. Cynical hostility is defined by high anger and frequent thoughts that other people cannot be trusted. Someone with hostility doesn’t just think, “I hate to stand in long lines” ; they think, “Others deliberately sped up and beat me to my rightful position in the line!”—and then get violently agitated. People who score high on measures of cynical hostility tend to get more heart disease, metabolic disease and often die at younger ages. They also have shorter telomeres. In a study of British civil servants, men who scoredhigh on measures of cynical hostility had shorter telomeres than men whose hostility scores were low. The most hostile men were 30% more likely to have short telomeres.What this means: aging is a dynamic process that could possibly be accelerated or slowed—and, in some aspects, even reversed. To an extent, it has surprised us and the rest of the scientific community that telomeres do not simply carry out the commands issued by your genetic code. Your telomeres are listening to you. The foods you eat, your response to challenges, the amount of exercise you get, and many other factors appear to influence your telomeres and can prevent premature aging at the cellular level. One of the keys to enjoying good health is simply doing your part to foster healthy cell renewal.46. What have scientists come to know better today?A) Why people age at different rates.B) How genes influence the aging process.C) How various genes express themselves in aging.D) Why people have long been concerned about aging.47. Why are some lifestyle factors considered extremely important?A) They may shorten the process of cell division.B) They may determine how genes function.C) They may affect the lifespan of telomeres.D) They may account for the stresses on cells.48. What have the author and his colleagues discovered about telomeres?A) Their number affects the growth of cells.B) Their length determines the quality of life.C) Their shortening process can be reversed.D) Their health impacts the division of cells.49. What have scientists learned about cynical hostility?A) It may lead to confrontational thought patterns.B) It may produce an adverse effect on telomeres.C) It may cause people to lose their temper frequently.D) It may stir up agitation among those in long lines.50. What do we learn from the last paragraph about the process of aging?A) It may vary from individual to individual.B) It challenges scientists to explore further.C) It depends on one’s genetic code.D) It may be controlled to a degree.Passage TwoQuestions 51 to 55 are based on the following passage.Scientists have created by accident an enzyme ( 酶) that breaks down plastic drinks bottles. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles.。

Buffington says he found a soda bottle half-buried in the sand that looked like it had been there since the beginning of time.The note inside the bottle said, "Return to 419 Ocean Street and receive a reward of $150 from Richard and Tina Pierce, owners of the beach Comber motel.The motel was owned by the Paula Pierce in 1960. Her father had written the notes as a joke and had thrown it into the Atlantic Ocean. Buffington flew to New Hampshire to deliver that message to Pola Pierce. She held up to her father's promise giving Buffington that reward. But the biggest reward is the message in a bottle finding its way back home.Questions 1 and 2 are based on the news report you have just heard.1. What is the news report mainly about?2. Why did Paula Pierce give Clint Buffington the reward?News Report TwoMillions of bees have died in South Carolina during aerial insect spraying operations that were carried out to combat the Zika virus. The insects spraying over the weekend left more than 2 million bees dead on the spot in Dorchester county South Carolina, where four travel-related cases of Zika disease have been confirmed in the area. Most of the deaths came from Flower Town Bee farm, a company in Somerville that sells bees and honey products. Juanita Stanley who owns the company said the farm looks like it's been destroyed. The farm lost about 2.5 million bees. Dorchester county officials apologized for the accidental mass killing of bees.Dorchester County is aware that some beekeepers in the area that was sprayed on Sunday lost their bee colonies.County manager Jason Ward said in a statement. “I'm not pleased that so many bees were killed.”Questions 3 and 4 are based on the news report you have just heard.3. Why was spraying operations carried out in Dorchester County?4.

The Airlander 10 spent nearly 2 hours in the air having taken off from Coddington airfield in Bedfordshire. During its flight it reached 3000 feet and performed a series of gentle turns all over a safe area. The aircraft is massive as long as a football field and as tall as 6 double decker buses and capable of flying for up to 5 days. It was first developed for the US government as a long range spy aircraft, but was abandoned following budget cutbacks. The aircraft cost25 million pounds and can carry heavier loads than huge jet planes while also producing less noise and omittingless pollution. The makers believe it's the future of aircraft and one day we'll be using them to go places. But there's still a long way to go. The Airlander will need to have 200 hours flying time before being allowed to fly by the aviation administration if it passes though we can hope we'll all get some extra legroom.Questions 5 and 7 are based on the news report you have just heard.5.

A new study in mice may help to explain why hunger can feel like such a powerful motivating force. In the study, researchers found that hunger outweighed other physical drives, including fear, thirst and social needs.To determine which feeling won out, the researchers did a series of experiments. In o ne experiment, the mice were both hungry and thirsty. When given the choice of either eating food or drinking water, the mice went for the food, the researchers found. However, when the mice were well-fed but thirsty, they opted to drink, according to the study. In the second experiment meant to pit the mice's hunger against their fear, hungry mice were placed in a cage that had certain "fox-scented" areas and other places that smelled safer (in other words, not like an animal that could eat them) but also had food. It turned out that, when the mice were hungry, they ventured into the unsafe areas for food. But when the mice were well-fed, they stayed in areas of the cage thatwere considered "safe." Hunger also outweighed the mice's social needs, the resear chers found. Mice are usually social animals and prefer to be in the company of other mice, according to the study. When the mice were hungry, they opted to leave the company of other mice to go get food.Questions 16 to 18 are based on the passage you have just heard.16. What is the researchers’ purpose in carrying out the serious experiment with mice?17. In what circumstances, do mice venture into unsafe areas?18. What is said about mice at the end of the passage?Passage TwoThe United States has one of the best highway systems in the world. Interstate highways connect just about every large and mid-sized city in the country. Did you ever wonder why such a complete system of excellent roads exists? For an answer，you would have to go back to the early 1920s. In those years, just after World War I, the military wanted to build an American highway system for national defense. Such a system could, if necessary, move troops quickly from one area to another. It could also get people out of cities in dan ger of being bombed. So-called roads of national importance were designated, but they were mostly small country roads. In 1944, Congress passed a bill to upgrade the system, but did not fund the plan right away. In the 1950s, the plan began to become a reality. Over $25 billion was appropriated by congress, and construction began on about 40,000 miles of new roads. The idea was to connect the new system to existing expressways and freeways. And though the system was built mostly to make car travel easier, defense was not forgotten. For instance, highway overpasses had to be high enough to allow trailers carrying military missiles to pass under them. By 1974, this system was mostly completed. A few additional roads would come later. Quick and easy travel between all parts of the country was now possible.Questions 19 and 21 are based on the passage you have just heard.19. What does the speaker say about the American highway system?20. What was the original purpose of building a highway system?21. When was the interstate highway system mostly completed?Passage ThreeTexting while driving was listed as a major cause of road deaths among young Americans back in 2013. A recent study said that 40% of American teens claim to have been in a car when the driver used a cell phone in a way that put people in danger. This sounds like a widespread disease but it's one that technology may now helped cure. T.J. Evarts, a 20- year-old inventor, has come up with a novel solution that could easily put texting drivers on notice. It's called Smart Wheel, and it's designed to fit over the steering wheel of most standard vehicles to track whether or not the driver has two hands on the wheel at all times. Evarts’ invention warns the drivers with the light and the sound when they hold the wheel with one hand only, but as soon as they place the other hand back on the wheel the light turns back to green and the sound stops. It also watches for what's called “close by hands”, where both hands are close together near the top o f the wheel so the driver can type with both thumbs and drive at the same time. All the data Smart Wheel collects is also sent to a connected app. So any parents who install Smart Wheel can keep track of the teens’ driving habits. If they try to remove or damage the cover, that's reported as well.Questions 22 to 25 are based on the passage you have just heard.22. What is a major cause of road deaths among young Americans?23. What is Smart Wheel?24. What happens if the driver has one hand on the wheel?25. How do parents keep track of their teens’ driving habits?参考答案：ABBCA CDADC BDCAD BACDB ABACB2听力第二套参考答案：Section A1.

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。

Answer the question by marking thecorresponding letter on Answer Sheet 2.The start of high school does n’t have to be stressful[A] This month, more than 4 million students across the nation will begin high school. Many willdo well. But many will not. Consider that nearly two-thirds of students will experience the “ninth-grade shock,” which refers to a dramatic drop in a student’s academic performance. Somestudents cope with this shock by avoiding challenges. For instance, they may drop rigorous coursework. Others may experience a hopelessness that results in failing their core classes, such as English, science and math.[B] This should matter a great deal to parents, teachers and policymakers. Ultimately it shouldmatter to the students themselves and society at large, because students’experience of transitioning（过渡）to ninth grade can have long-term consequences not only for the students but for their home communities. We make these observations as research psychologists who have studied how schools and families can help young people thrive.[C] In the new global economy, students who fail to finish ninth grade with passing grades in collegepreparatory coursework are very unlikely to graduate on time and go on to get jobs. One study has calculated that the lifetime benefit to the local economy for a single additional student who completes high school is half a million dollars or more. This is based on higher earnings and avoided costs in health care, crime, welfare dependence and other things.[D] The consequences of doing poorly in the ninth grade can impact more than students’ ability tofind a good job. It can also impact the extent to which they enjoy life. Students lose many of the friends they turned to for support when they move from eighth to ninth grade. One study of ninth grade students found that 50 percent of friendships among ninth graders changed from one month to the next, signaling striking instability in friendships.[E] In addition, studies find the first year of high school typically shows one of the greatest increasesin depression of any year over the lifespan. Researchers think that one explanation is that ties to friends are broken while academic demands are rising. Furthermore, most adult cases of clinical depression first emerge in adolescence（青春期）. The World Health Organization reports that depression has the greatest burden of disease, in terms of the total cost of treatment and the loss of productivity.[F] Given all that’s riding on having a successful ninth grade experience, it pays to explore what canbe done to improve the academic, social and emotional challenges of the transition to high school.So far, our studies have yielded one main insight: Students’ beliefs about change – their beliefs about whether people are stuck one way forever, or whether people can change their personalities and abilities –are related to their ability to cope, succeed academically and maintain good mental health. Past research has called these beliefs “mindsets（思维模式）,”with a “fixed mindset” referring to the belief that people cannot change and a “growth mindset”referring to the belief that people can change.[G] In one recent study, we examined 360 adolescents’ beliefs about the nature of “smartness”– thatis, their fixed mindsets about intelligence. We then assessed biological stress responses for students whose grades were dropping by examining their stress hormones（荷尔蒙）. Students who believed that intelligence is fixed – that you are stuck being “not smart” if you struggle inschool –showed higher levels of stress hormones when their grades were declining at the beginning of ninth grade. If students believed that intelligence could improve – that is to say, when they held more of a growth mindset of intelligence – they showed lower levels of stress hormones when their grades were declining. This was an exciting result because it showed that the body’s stress responses are not determined solely by one’s grades. Instead, declining grades only predicted worse stress hormones among students who believed that worsening grades werea permanent and hopeless state of affairs.[H] We also investigated the social side of the high school transition. In this study, instead ofteaching students that their smartness can change, we taught them that their social standing –that is, whether you are bullied or excluded or left out – can change over time. We then looked at high school students’ stress responses to daily social difficulties. That is, we taught them a growth mindset about their social lives. In this study, students came into the laboratory and were asked to give a public speech in front of upper-year students. The topic of the speech was what makes one popular in high school. Following this, students had to complete a difficult mental math task in front of the same upper-year students.[I] Experiment results showed that students who were not taught that people can change showedpoor stress responses. When these students gave the speech, their blood vessels contracted and their hearts pumped less blood through the body – both responses that the body shows when it is preparing for damage or defeat after a physical threat. Then they gave worse speeches and made more mistakes in math. But when students were taught that people can change, they had better responses to stress, in part because they felt like they had the resources to deal with the demanding situation. Students who got the growth mindset intervention（干预）showed less- contracted blood vessels and their hearts pumped more blood – both of which contributed to more oxygen getting to the brain, and, ultimately, better performance on the speech and mental math tasks.[J] These findings lead to several possibilities that we and others are investigating further. First, we are working to replicate（复制）these findings in more diverse school communities. We want to know in which types of schools and for which kinds of students these growth mindset ideas help young people adapt to the challenges of high school. We also hope to learn how teachers, parents or school counselors can help students keep their ongoing academic or social difficulties in perspective. We wonder what would happen if schools helped to make beliefs about the potential for change and improvement a larger feature of the overall school culture, especially for students starting the ninth grade.36.The number of people experiencing depression shows a sharp increase in the first year of high school.37.According to one study, students’ academic performance is not the only decisive factor of their stress responses.38.Researchers would like to explore further how parents and schools can help ninth graders by changing their mindset.39.According to one study, each high school graduate contributes at least 500,000 dollars to the local economy.40.In one study, students were told their social position in school is not unchangeable.41.It is reported that depression results in enormous economic losses worldwide.42.One study showed that friendships among ninth graders were far from stable.43.More than half of students will find their academic performance declining sharply when they enter the ninth grade.44.Researchers found through experiments that students could be taught to respond to stress in more positive way.45.It is beneficial to explore ways to cope with the challenges facing students entering high school.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) andD). 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 to 50 are based on the following passage.Boredom has become trendy. Studies point to how boredom is good for creativity and innovation, as well as mental health. For example, a 2014 study published in the Creativity Research Journal found that people were more creative following the completion of a tedious task. Another piece of research published in the same year by the Journal of Experimental Social Psychology found that when people were bored, they had an increase in “associative thought”—the process of making new connections between ideas, which is linked to innovative thinking. These studies are impressive, but in reality, the benefits of boredom may be related to having time to clear your mind, be quiet, or daydream.The truth is, pure boredom isn’t pleasant. One study published in Science found that participants (67% of men and 25% of women) chose to administer an electric shock to themselves rather than to sit and think quietly for 6 to 15 minutes. In addition, a Washington State University study shows boredom is on the rise, especially in adolescent girls. This is a problem, since boredom can have negative consequences that lead to everything from overeating to issueswith drugs, drinking, or gambling.In our stimulation-rich world, it seems unrealistic that boredom could occur at all. Yet, there are legitimate reasons boredom may feel so painful. As it turns out, boredom might signal the fact that you have a need that isn’t being met.Our always-on world of social media may result in more connections, but they are superficial and can get in the way of building a real sense of belonging. Feeling bored may signal the desire for a greater sense of community and the feeling that you fit in with others around you. So take the step of joining a club, organization, or association to build face-to-face relationships and create new friendships. You’ll find depth that you won’t get from your screen no matter how many likes you get on your post.Similar to the need for belonging, bored people often report that they feel a limited sense of meaning. It’s a fundamental human need to have a larger purpose and to feel like we’re part of something bigger than ourselves. A 2007 University of Mississippi study found that when people are bored, they’re more likely to feel less meaning in their lives and vice versa. Conversely, a 2016 study by the University of Southampton found that when people volunteered, their happiness increased. If you want to reduce boredom and increase your sense of meaning, seek work that matters to you where you can make a unique contribution, or find a cause you can support with your time and talents.People have varying needs for stimulation and adrenaline rushes, but in general, boredom may be a signal that you need to push yourself a bit. This could be a stretch at work or in your leisure activities. After all, happiness is correlated with being challenged and developing new skills, and scrolling through your social media accounts doesn’t meet this requirement. So find opportunities to try new things, whether it’s skydiving, taking on a tough project at work, or starting a hobby that provides a fun outlet.One of the aspects of boredom is feeling like things are the same from day to day and week to week. Some predictability is good for mental health, but you may also need some variety in your life. Invite people of different backgrounds into your friend group, join the unexpected interest group at work, or read more widely on unusual topics. The key is to broaden your perspective and change what you’re exposed to regularly.In The Shallows: What the Internet Is Doing to Our Brains, journalist Nicholas Carr makes a strong case for the ways our brains have been rewired to glaze the surface of things, rather than to go deep. But the ability to have more depth, process deeply, and get into flow are hallmarks of empathy, connectedness, and happiness. Find a project that you can lose yourself in, because it’s so exciting, or set aside time to solve a thorny problem. These kinds of deep thinking can go far in alleviating boredom.If your definition of boredom is being quiet, mindful, and meditative, keep it up. But if you’rewrestling with real boredom and the emptiness it provokes, consider whether you might seek new connections, more meaning, more significant challenges, diversity of experiences, or more depth in your efforts. These are the things that will genuinely alleviate boredom and make you more effective in the process.46.A）It facilitates innovative thinking.47.B）A desire to be fulfilled.48.C）It may prevent people from developing a genuine sense of community.49.C）Engage in real-life interaction.50.D）Devote themselves to a worthy cause.Passage TwoQuestions 51 to 55 are based on the following passage.Can you remember what you ate yesterday? If asked, most people will be able to dredge up a vague description of their main meals: breakfast, lunch, dinner. But can you be sure you’ve noted every snack bar en route to the car, or every handful of nuts at your desk? Most people will have the lingering feeling that they’ve missed something out.We originally had this suspicion back in 2016, puzzled by the fact that national statistics showed calorie consumption falling dramatically over past decades. We found reliable evidence that people were drastically under-reporting what they ate – and the problem was getting worse over time.Now the Oﬃce for National Statistics has responded to our report by conﬁrming its ﬁndings: we are consuming 50% more calories than our national statistics claim.Why is this happening? We can point to at least three potential causes. One is the rise in obesity levels itself. There is good evidence that under-reporting rates are much higher for obese people. The main reason for this seems to be that obese people simply consume more food, and thus have more to remember.Another cause is that the proportion of people who are trying to lose weight has been increasing over time (from 40% in 1997 to 50% in 2013, for example). People who want to lose weight are around 10 percentage points more likely to under-report their eating – regardless of whether they are overweight or not. This may be driven partly by self-deception or “wishful thinking”.The ﬁnal potential cause is an increase in snacking and eating out over recent decades – both in terms of how often they happen and how much they contribute to our overall energy intake. The amount of time spent eating out doubled between 1975 and 2000, for example. By 2015, one in ﬁve meals was eaten outside the home. This trend means it is more diﬃcult for us to keep track of what we eat, not least because we have to remember more eating events. Again, there is evidence for this – food consumed out of the home is one of the most poorly recorded categories in surveys.We will be presenting these ﬁndings in a BBC documentary called The Truth About Obesity. However, we want to stress that they are not just interesting statistical nuggets. First, the diﬀerences we are talking about are huge – men are consuming 1,000 more calories a day than previous ﬁgures suggested. This is the equivalent of not reporting that you ate a whole pepperoni pizza.Second, these statistics guide and underpin policy. There is much concern about the healtheﬀects of obesity, but what do we do to reduce it? Based on the old numbers, our food consumption would not be seen as the problem: it seems to be below recommended intakes, and falling. So policymakers may be tempted to look elsewhere – perhaps to increasing physical activity instead. We showed that this is not the most eﬀective way of preventing obesity, given that it takes much more eﬀort to burn calories than consume them.So, what’s the takeaway? For statistics, we should invest in more accurate measurement options – these do exist, but they can be expensive. For policy, we need to focus on options that make it easy for people to eat fewer calories. If people do not know how much they are eating, it can be really hard for people to stick to a diet. Instead, we should be looking for new ways to incentivise and achieve food reformulation. If this works, then people would not need to try to eat less –it’s just that what they eat wouldn’t have the same impact on their waistlines. And it won’t matter so much if they can’t remember whether it was a muﬃn or a croissant yesterday morning.51.C) The national statistics did not reflect the actual calorie consumption.52.A) People' s calorie intake was far from accurately reported.53.B) They overlook the potential causes of obesity.54.B) The potential causes of snacking.55.B)Make sure people eat non-fattening food.Part IV Translation (30 minutes)Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.

Each.choice in the bank is identified by a letter.Please mark the corresponding letter for each item on Answer Sheet2 with a single line through the center.You may not use any of the words in the bank more than once.Questions 36 to 45 are based on the following passage.Children do not think the way adults do.For most of the first year of life, if something is out of sight, it's out of mind.If you cover a baby's36toy with a piece of cloth, the baby thinks the toyhas disappeared and stops looking for it.A 4-year-old may 37 that a sister has more fruit juicewhen it is only the shapes of the glasses that differ, not the38 of juice.Yet children are smart in their own way.Like good little scientists, children are always testing their child-sized39 about how things work.When your child throws her spoon on the floor for the sixth time as you try to feed her, and you say, "That's enough! I will not pick up your spoon again!"the child will 40 test your claim.Are you serious? Are you angry? What will happen if she throws the spoon again? She is not doing this to drive you41; rather, she is learning that her desires and yours can differ, and that sometimes those42 are important and sometimes they are not.How and why does children's thinking change? In the 1920s, Swiss psychologist Jean Piaget proposed that children's cognitive (认知旳) abilities unfold 43, like the blooming of a flower,almost independent of what else is44in their lives.Althoughmany of his specific conclusions havebeen45 or modified over the years, his ideas inspired thousands of studies by investigators all over the world.A. advocateB. amountC. confirmedD. crazyE. definiteF. differencesG. favoriteH. happeningI.

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 Perfect EssayA.Looking back on too many years of education, I can identify one truly impossible teacher.Shecared about me, and my intellectual life, even when I didn't.Her expectations were high--impossibly so.She was an English teacher.She was also my mother.B.When good students turn in an essay, they dream of their instructor returning it to them in exactly the same condition, save for a single word added in the margin of the final page : "Flawless." This dream came true for me one afternoon in the ninth grade.Of course, I had heard that genius could show itself at an early age, so I was only slightly taken aback that I had achieved perfection at the tender age of 14.Obviously, I did what any professional writer would do; I hurried off to spread thegood news.I didn't get very far.The first person I told was my mother.C.My mother, who is just shy of five feet tall, is normally incredibly soft-spoken, but on the rareoccasion when she got angry, she was terrifying.I am not sure if she was more upset by my hubris(得意忘形) or by the fact that my English teacher had let my ego get so out of hand.In any event,my mother and her red pen showed me how deeply flawed a flawless essay could be.At the time,I am sure she thought she was teaching me about mechanics, transitions (过渡), structure, style and voice.But whatI learned, and what stuck with me through my time teaching writing at Harvard, wasa deeper lesson about the nature of creative criticism.D.First off, it hurts.Genuine criticism, the type that leaves a lasting mark on you as a writer, also leaves an existential imprint (印记) on you as a person.I have heard people say that a writer should never take criticism personally.I say that we should never listen to these people.E. Criticism, at its best, is deeply personal, and gets to the heart of why we write the way we do. Theintimate nature of genuine criticism implies something about who is able to give it, namely,someone who knows you well enough to show you how your mental life is getting in the way of good writing.Conveniently, they are also the people who care enough to see you through this painful realization.For me it took the form of my first, and I hope only, encounter with writer'sblock--I was not able to produce anything for three years.F. Franz Kafka once said: "Writing is utter solitude (独处), the descent into the cold abyss (深渊) of oneself." My mother's criticism had shown me that Kafka is right about the cold abyss, and when you make the introspective (内省旳) descent that writing requires you are not always pleased by what you find.But, in the years that followed, her sustained tutoring suggested that Kafka might be wrong about the solitude.I was lucky enough to find a critic and teacher who was willing to make the journey of writing with me."It is a thing of no great difficulty," according to Plutarch, "to raise objections against another man's speech, it is a very easy matter; but to produce a better in its place is a work extremely troublesome." I am sure I wrote essays in the later years of high school without my mother's guidance, but I can't recall them.What I remember, however, is how she took up the "extremely troublesome" work of ongoing criticism.G. There are two ways to interpret Plutarch when he suggests that a critic shouldbe able to produce "a better in its place." In a straightforward sense, he could mean that a critic must be more talented than the artist she critiques (评论).My mother was well covered on this count.But perhapsPlutarch is suggesting something slightly different, something a bit closer to Marcus Cicero's claim that one should "criticize by creation, not by finding fault." Genuine criticism creates a precious opening for an author to become better on his own terms--a process that is often extremely painful,but also almost always meaningful.H. My mother said she would help me with my writing, but first I had to help myself.For each assignment, I was to write the best essay I could.Real criticism is not meant to find obvious mistakes, so if she found any--the type I could have found on my own--I had to start from scratch.From scratch.Once the essay was "flawless," she would take an evening to walk me through myerrors.That was when true criticism, the type that changed me as a person, began.I. She criticized me when I included little-known references and professional jargon (行话).She had no patience for brilliant but irrelevant figures of speech."Writers can't bluff (虚张声势) their way through ignorance." That was news to me--I would need to freed another way to structure my daily existence.J. She trimmed back my flowery language, drew lines through my exclamation marks and argued for the value of restraint in expression."John," she almost whispered.I leaned in to hear her:"I can'thear you when you shout at me." So I stopped shouting and bluffing, and slowly my writingimproved.K. Somewhere along the way I set aside my hopes of writing that flawless essay.Butperhaps I missed something important in my mother's lessons about creativity and perfection.Perhaps the point of writing the flawless essay was not to give up, but to never willingly finish.Whitman repeatedly reworked "Song of Myself' between 1855 and 1891.Repeatedly.We do our absolute best with apiece of writing, and come as close as we can to the ideal.And, for the time being, we settle.Incritique, however, we are forced to depart, to give up the perfection we thought we had achieved for the chance of being even a little bit better.This is the lesson I took from my mother: If perfection were possible, it would not be motivating.46.The author was advised against the improper use of figures of speech.47.The author's mother taught him a valuable lesson by pointing out lots of flaws in his seemingly perfect essay.48.A writer should polish his writing repeatedly so as to get closer to perfection.49.Writers may experience periods of time in their life when they just can't produce anything.50.The author was not much surprised when his school teacher marked his essay as "flawless".51.Criticizing someone's speech is said to be easier than coming up with a better one.52.The author looks upon his mother as his most demanding and caring instructor.53.The criticism the author received from his mother changed him as a person.54.The author gradually improved his writing by avoiding fancy language.55.Constructive criticism gives an author a good start to improve his writing.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.andD .You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the center.Passage OneQuestions 56 to 60 are based on the following passage.Could you reproduce Silicon Valley elsewhere, or is there something unique about it?It wouldn't be surprising if it were hard to reproduce in other countries, because you couldn'treproduce it in most of the US either.What does it take to make a Silicon Valley?It's the right people.If you could get the right ten thousand people to move from Silicon Valley to Buffalo, Buffalo would become Silicon Valley.You only need two kinds of people to create a technology hub (中心) : rich people and nerds (痴迷科研旳人).Observation bears this out.Within the US, towns have become star,up hubs if and only if they have both rich people and nerds.Few startups happen in Miami, for example, because although it's full of rich people, it has few nerds.It's not the kind of place nerds like.Whereas Pittsburgh has the opposite problem: plenty of nerds, but no rich people.The top US Computer Science departments are said to be MIT, Stanford, Berkeley, andCarnegie-Mellon.MITyielded Route 128.Stanford and Berkeley yielded Silicon Valley.But what did Carnegie-Mellon yield in Pittsburgh? And what happened in Ithaca, home of Cornell University, which is also high on the list?I grew up in Pittsburgh and went to college at Cornell, so I can answer for both.The weather is terrible, particularly in winter, and there's no interesting old city to make up for it, as there is inBoston.Rich people don't want to live in Pittsburgh or Ithaca. So while there're plenty of hackers (电脑迷) who could start startups, there's no one to invest in themDo you really need the rich people? Wouldn't it work to have the government invest in the nerds?No, it would not.Startup investors are a distinct type of rich people.They tend to have a lot of experience themselves in the technology business.This helps them pick the right startups, and means they can supply advice and connections as well as money.And the fact that they have a personal stake in the outcome makes them really pay attention.56.What do we learn about Silicon Valley from the passage?A.Its success is hard to copy anywhere else.B.It is the biggest technology hub in the US.C.Its fame in high technology is incomparable.D.It leads the world in information technology.57.What makes Miami unfit to produce a Silicon Valley?ck of incentive for investment.ck of the right kind of talents.ck of government support.ck of famous universities.58.In what way is Carnegie-Mellon different from Stanford, Berkeley and MIT?A.Its location is not as attractive to rich people.B.Its science departments are not nearly as good.C.It does not produce computer hackers and nerds.D.It does not pay much attention to business startups.59.What does the author imply about Boston?A.It has pleasant weather all year round.B.It produces wealth as well as high-tech.C.It is not likely to attract lots of investors and nerds.D.It is an old city with many sites of historical interest.60.What does the author say about startup investors?A.They are especially wise in making investments.B.They have good connections in the government.C.They can do more than providing money.D.They are rich enough to invest in nerds.Passage TwoQuestions 61 to 65 are based on the following passage.It's nice to have people of like mind around.Agreeable people boost your confidence and allow you to relax and feel comfortable.Unfortunately, that comfort can hinder the very learning that can expandyour company and your career.It's nice to have people agree, but you need conflicting perspectives to dig out the truth.If everyone around you has similar views, your work will suffer from confirmation bias (偏颇).Take a look at your own network.Do your contacts share your point of view on most subjects? If yes, it's time to shake things up.As a leader, it can be challenging to create an environment in which people will freely disagree and argue, but as the saying goes: From confrontation comes brilliance.It's not easy for most people to actively seek conflict.Many spend their lives trying to avoidarguments.There's no need to go out and find people you hate, but you need to do some self-assessment to determine where you have become stale in your thinking.You may need to start by encouraging your current network to help you identify your blind spots.Passionate, energetic debate does not require anger and hard feelings to be effective.But it do esrequire moral strength. Once you have worthy opponents, set some ground rules so everyone understands responsibilities and boundaries.The objective of this debating game is not to win but to get to the truth that will allow you to move faster, farther, and better.Fierce debating can hurt feelings, particularly when strong personalities are involved. Make sure you check in with your opponents so that they are not carryingthe emotion of the battles beyond thebattlefield.Break the tension with smiles and humor to reinforce the idea that this is friendly discourse and that all are working toward a common goal.Reward all those involved in the debate sufficiently when the goals are reached.Let your sparring partners (拳击陪练) know how much you appreciate their contribution. The more they feel appreciated, the more they'll be willing to get into the ring next time.61.What happens when you have like-minded people around you all the while?A.It will help your company expand more rapidly.B.It will create a harmonious working atmosphere.C.It may prevent your business and career from advancing.D.It may make you feel uncertain about your own decisions.62.What does the author suggest leaders do?A.Avoid arguments with business partners.B.Encourage people to disagree and argue.C.Build a wide and strong business network.D.Seek advice from their worthy competitors.63.What is the purpose of holding a debate?A.To find out the truth about an issue.B.To build up people's moral strength.C.To remove misunderstandings.D.To look for worthy opponents.64.What advice does the author give to people engaged in a fierce debate?A.They listen carefully to their opponents' views.B.They show due respect for each other's beliefs.C.They present their views clearly and explicitly.D.They take care not to hurt each other's feelings.65.How should we treat our rivals after a successful debate?A.Try to make peace with them.B.Try to make up the differences.C.Invite them to the ring next time.D.Acknowledge their contribution.Part Ⅳ Translation( 30 minutes )Directions: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.You should write your answer on Answer Sheet 2.今年在长沙举行了一年一度旳外国人汉语演讲比赛.这项比赛证明是增进中国和世界其他地区文化交流旳好措施.它为世界各地旳年轻人提供了更好地理解中国旳机会.来自87个国家合计126位选手汇集在湖南省省会参与了从7月6日到8月5日进行旳半决赛和决赛.比赛并不是唯一旳活动.选手们尚有机会参观了中国其他地区旳著名景点和历史名胜.12月大学英语四级考试真题答案与详解(第3套)Part Ⅰ Writing这是一篇四级考试中常见旳议论文.话题围绕“Never go out there to see what happens，go out there to make things happen.”这句话展开，规定考生进行评论，同步在题目规定中也明确给出了作文主题the importance of being participants rather than mere onlookers in life.考生应当明确这一主题，并围绕其展开论述.一、点明主题：不做看客，要做实践者(being participants instead of onlookers in life)二、分析原因三、提出问题和提议主题词汇put…into practice将……付诸实践carry out执行；实现gain获得accumulate积累gradually逐渐地make a progress获得进步theory理论action行动would rather…t han比起……更情愿……stand by袖手旁观句式拓展1.For some people, watching what happens to others is good enough to learn a lesson, while for others, only practicing by themselves can finally make them get the real skills in对某些人而言，看发生在他人身上旳事情足以让他们吸取教训，而对于其他人而言，他们只有亲身实践才能最终得到生活中旳真正技能.2.No matter how many authentic theories you've got before,nothing will happen until you put them into practice.无论你曾经接受了多少权威旳理论，若不付诸实践，一切都无济于事.Part ⅡListening ComprehensionM: I don't know what to do with Timmy.This morning I found orange juice spilled all over the kitchen floor.W: Don't be so hard on him.He's only four.Q: What does the woman mean?C.四个选项中出现了children，careful，juice和Timmy等词，故推测本题考察旳内容与孩子旳行为有关.对话中，男士埋怨说他都不懂得该拿蒂米怎么办了，今天早上，他发现桔子汁在厨房洒了一地，而女士则说，别对蒂米太严厉了，他才四岁.由此可见，女士认为男士不用小题大做，故答案为C..2.W: Excuse me, sir.I would like to know about the fitness training program in your club.M: I'll have you speak with the director in charge of new accounts.Q: What is the woman interested in?A.四个选项均为名词短语，且出现了fitness，job，computer和club等词，故推测本题考察旳内容与健身或者工作有关.对话中，女士向男士问询俱乐部健身锻炼旳事情，男士则说他会带着女士去找专门负责新会员旳经理.由此可知，女士是对俱乐部健身锻炼感爱好，故答案为A..3.W: It's really cold in this apartment.Can we turn up the heat a little bit?

Part III Reading Comprehension (40 minutes)Section ADirections: In this section, there is a passage with ten blanks. 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 thebank is identified by a letter: Please mark the corresponding letter for each item onAnswer Sheet 2 with a single line through the centre. You may not use any of thewords in the bank more than once.Questions 26 to 35 are based on the following passageThe things people make, and the way they make them, determine how cities grow and decline, and influence how empires rise and fall. 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.

Part Ⅲ Reading Comprehension ( 40 minutes )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 2with a single line through the centre.Passage OneQuestions 46 and 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.“It 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.“Right 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 understand 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 lifespancan 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. Whatdo people generally believe about agingA) It should cause not alarm whatsoever.B) They just cannot do anything about it.C) It should be regardedas a kind of disease.D) They can delay it with advances in science.do many scientists view aging nowA) It might be prevented and treated. C) It results from a vitamin deficiency.B) It can be as risky as heart disease. D) It is an irreversible biological process.48. What does Alex Zhavoronkov think of “describing aging asa 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. What do we learn about the medical communityA) 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 believeA) 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 Kuheli Dutt, 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 withtheir 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 out-standing 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 toopen upmeaningful 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 geosciencesA)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 showA) Women engaged in postdoctoralwork are quickly catching up.B) Fewer women are applying for postdoctoralpositions 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 applicantsA) 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 recommendationA) 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 studyA) Raise recommendation writers’awareness of gender bias in their letters.B) Open up fresh avenues for women post-doctors to join in reaserach 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: For this part, you are allowed 30 minutes to translate a passage from Chinese into English.
