Part I Writing
As is vividly illustrated in the picture, “there is no I in TEAM”. The above picture depicts the importance of cooperation in whatever tasks a team undertakes. As far as I am concerned, if a team intends to achieve its goal, each member of the team is supposed to forget about his or her self-interest and contribute to the whole.
It is generally believed that cooperation is of great importance to the final success of a team. On one hand, without cooperation, a person or an organization is unable to accomplish much, especially in this increasingly interdependent society. On the other hand, it is cooperation that can integrate the strengths of each member of a group and contribute to the achievement of the target. Therefore, under no circumstances should we neglect the positive impacts brought by cooperation.
In conclusion, in order to benefit each individual, we should lay great emphasis on cooperation, which has become a consensus among modern individuals. Only when each member of a team realizes the significance of being cooperative, can the ultimate success be achieved and can each individual benefit from the achievement.

Part IV Translation
Traditional Chinese holiday meals are indispensable on some festivals. For example, the Dragon Boat Festival is a day established in memory of the ancient poet Qu Yuan and people usually hold dragon boat races and eat zongzi, or rice dumpling on that day. The Mid-autumn Festival is an occasion for viewing the full moon. The round moon is a symbol for completeness and family reunion. Therefore, the special food of the day is a round cake known as the moon cake. The Spring Festival is the Chinese lunar New Year's holiday. Besides the popular poultry and meat，people cook traditional food according to regional customs, for example, jiaozi, or boiled dumplings, and niangao, or the “new year cake”.。

(3)There should be several ways to deal with this problem.(4)First, some of the rubbish can be reused after a proper treatment, such as wastepaper, bottles, metals, etc. People in the city should be told to classify their rubbish and the city government should collect the rubbish in time. In this way a large amount of rubbish can be retrieved, and reused.(5)Second, the government should carry out some policies on the problem of littering and arouse people’s awareness of environmental protection. (6)By accepting the two suggestions mentioned above, the wastes can be made full use of and the city environment can be well protected.解析：第一段总述图画呈现的内容。

You should start your essay with a brief description of the picture and then express your views on the secret to happiness. You should write at least 120 words but no more than 180 words.”The secret to happiness is to blame other people for your troubles. “正确答案：The Secret to Happiness As is shown in the picture, after a long trip a young man finally gets the secret to happiness from an old man, that is, “to blame other people for your troubles”, which was quite beyond his expectations. I strongly disapprove of this negative attitude towards life and happiness. In my opinion, the secret to happiness is to stop blaming others and bravely face up to our own problems. There is no blame, complaints or regrets on the road to happiness, let alone blaming others for your own problems, which is a kind of disgraceful coward behavior. People make mistakes. A courageous man faces up to his own faults and takes responsibility when things go wrong. Of course he will get applause and happiness in return in that only a man of integrity deserves happiness and blessing. Furthermore, blame is to happiness what poison is to human. One cannot obtain happiness unless he stops blaming others, which might lead to misunderstanding, anger, and even hatred. In short, happiness is the ever-lasting pursuit of mankind, easy to obtain and equal to everyone. Just stop blaming others and tell them it’s no big deal because you can handle it.Part II Listening ComprehensionSection A听力原文：W: I’m glad that you win the singing contest.

You should write at least 120 words but no more than 180 words. Write your essay on Answer Sheet 1.正确答案：Wechat in Our Life In recent years, Wechat is becoming increasingly popular. Many people express themselves, exchange ideas and deliver information by Wechat. There are a number of reasons for the popularity of Wechat. To begin with, Wechat is a relatively cheap way of communication, which cuts down a great deal of the cost of making a phone call, and we all know that saving money is the last word. Next, Wechat is to the taste of the majority of people. It is innovative and appealing in such an era when people seek and consume interesting and entertaining things to relieve stress from various aspects. Wechat’s attractive interface and various functions are loved wildly by young people. Furthermore, convenience also accounts for its popularity. It is available everywhere and at any time. Of course, Wechat is not perfect. Firstly, our identity can be revealed when using Wechat. Moreover, it may make communicating with others face to face less. Last but not the least, as college students, our attention might be drawn from study. Of course, it’s no doubt that Wechat will improve as time goes by.Part II Listening ComprehensionSection A听力原文：W: Did you turn off the lights and check the locks on all the doors? M: Yes.

TranslationPart I Writing1．For this part, you are allowed 30 minutes to write a short essay. You should start your essay with a brief account of student’s increasing reliance on technology to solve problems, and then explain the consequence of over-dependence on it. You should write at least120 words but no more than 180 words. “You have to solve this problem by yourself. You can’t call tech support.”正确答案：Technology Can’t Solve Every Problem As shown in the picture, a kid is trying to get the answer of a simple calculation from his smart phone. Unfortunately, this is just the tip of the iceberg. Students rely so much on technology to solve problems these days that they seek answers from Internet for their daily homework, examination and even graduation paper that needs deep thought and critical thinking. Though technology has brought much convenience to us, overuse of it, especially for students, does more harm than good. First, the “Google has it all” notion tempts student into laziness, and leads to their loss of basic skills. For example, many students now can’t spell correctly “thanks to”the spelling checking software. Second, technology can’t teach students critical thinking. Solving practical problems is far more complicated than copy-and-paste. Q and A websites don’t tell us the exact solution for every problem, and students need to learn the ability to think and analyze instead of copying the information technology mechanically provides. Advanced technology is certainly a blessing for students. Nevertheless, once overused, it can become a devil that kills our diligence and creativity.Part II Listening ComprehensionSection A听力原文：W: We’ve already bought an oven, a washing machine, a dishwasher, and a refrigerator. We don’t have much money left, do we? M: There’s still more than enough money for you to buy kitchen equipment.

The science and technology help people have more chances to discover new things. It is the basic principle of Marxism that science and technology are productive forces. Science and technology are symbols of national strength.(3)All in all, science and technology development has been accompanied with the development of human civilization.

These chemicals are said to be harmless to human health.(1)In fact. the chemicals are considered so safe that we wash with them. We put them on our bodies and even on our faces. Other chemical products are used throughout our homes. By the time you walk out your front door, you have already been exposed to thousands of chemicals. On its own, each chemical seems harmless. But in combination with other chemicals, they may become deadly. That is the finding of a two-year study by a task force of scientists.(2)The task force was told to investigate the cancer-causing probability of chemical mixtures. Their job was to study the cancer-causing potential of 85 chemicals. All 85 are said to be common in the environment. They explain that chemicals have the potential, or ability, to form dangerous mixtures.1. How do people see chemicals in life? 2.

Environmentalists in the United States and Europe say this insecticide is causing a drop in the number of bees. These insecticides are among the most commonly-used worldwide. Farmers often use seeds treated with the insecticides. The chemicals target insects that eat crops, and they do not spread beyond the field. But they do get into pollen(花粉)and nectar(花蜜), which is where the bees come into contact with them. Researchers studied bees in fields. They say there were about half as many wild bees per square meter in treated fields as in untreated ones. Using the chemicals too much may be hurting bees.(4)They suggest that the chemicals should be used more sensibly, or. in other words, only when necessary.3. Why are wild bees important? 4. What do researchers suggest when using chemicals?4．A．They are rare species.B．They protect the environment.C．They pollinate crops and wild plants.D．They protect crops and wild plants.正确答案：C5．A．Chemicals should be used as many as possible.B．Chemicals should be used only if necessary.C．Chemicals should be used as few as possible.D．Chemicals should be used once a month.正确答案：B听力原文： A deaf and blind woman from Australia has become the first person to make a telephone call using a device that converts speech into Braille.(5)The technology is being tested for the first time in Australia and the United States.

Ms. Stevens says the braille telephone will end years of feeling isolated, or feeling alone and apart from others. The Braille telephone system will be a great help to her and others. This telephone system will be one way to break the isolation of deaf-blindness.(6)She adds that with future developments, the phone system might be able to give deaf-blind people more job opportunities. Not being able to communicate in the office or on the telephone is a major employment barrier for people who are deaf-blind.

Scientists have confirmed that the majority of overweight people who try to lose weight either by cutting calories or exercising will return to their former size. Fewer than 10 percent of the 12 million Britons who go on a diet each year succeed in losing significant amounts of weight and most of those who do put it all back on again within a year. The scientists, from the Medical Research Council’s National Survey of Health and Development, followed 5,362 men and women from their birth in 1946 and 20,000 from birth in 1958, measuring their weight and blood pressure and assessing their lifestyles. They found both groups began gaining weight in the 1980s and had steadily increased in size ever since. Dr. Rebecca Hardy, the council’s program leader on body size,(17)said.”Once people become overweight. they continue relentlessly upwards. They hardly ever go back down. It is better to avoid getting fat in the first place. For men, weight goes up steadily through life. For women, it starts slowly and accelerates in the mid-thirties. “ Experts have suggested evolution means we are programmed to put on weight rather than lose it.(18)Dieting can make this tendency worse as decreasing calorie intake triggers the body to go into starvation mode and reduce the amount of energy it naturally expends. making it even harder to lose weight. But the study’s findings do not mean dieting is pointless, so eating less and taking more exercise can increase fitness and lower blood pressure.16. What have the failed dieters suspected? 17. What do scientists find after the long-time observation? 18. What role does dieting play in losing weight according to the passage?17．A．They can’t lose weight.B．They can lose weight by cutting calories or exercising.C．They really can’t keep the weight off.D．They should be on a diet to lose weight.正确答案：C18．A．Senior people are less likely to gain weight.B．Senior people are more likely to gain weight.C．Once people get fat, they will suffer various problems.D．Once people get fat, they gain weight steadily.正确答案：D19．A．It may have a negative influence.B．It plays a very significant role.C．It is meaningless.D．It can have a positive impact.正确答案：A听力原文： A common challenge for many teachers is keeping their students focused in class. After all, many children can become distracted, bored or confused in a classroom setting, or abandon their concentration on a lesson plan. There are various ways teachers can encourage their students to stay focused and make learning more interesting. Based on a lack of students’focus, teachers are sometimes given the impression that their lesson plan is not motivating or interesting to their students.(19)However, the problem might simply be that the students need change and movement. It often helps for teachers to alternate quiet activities in class with more active and exciting lessons. Something changing the pace of your lessons and activities can make all the difference in helping your students stay focused, and ultimately enjoy the lesson you’ve prepared for them. Children tend to remain more focused when interactive teaching tools are involved. For instance,(20)an interactive whiteboard in the classroom can help children feel included. and thus stay more focused. What’s more, it’s an effective teaching tool, helping instructors enhance lesson plans and students learning. So remember, the slightest change in how you deliver your lesson plans can make a world of difference when it comes to keeping your students focused. Above all,(21)to reach the best effect in class. the first thing for teachers is to know the students’ ability to maintain attention—for instance, based on their age group—and enhance lessons accordingly for optimal focus and fun in the classroom.19. What should teachers do to make students enjoy the class? 20. What is the function of the whiteboard in the class? 21. What should teachers know first to have the best effect in class?20．A．Prevent the students doing any movement.B．Give students more time to rest.C．Bring students more activities.D．Adopt the same teaching plan for a long time.正确答案：C21．A．It can help teachers interact with the students.B．It just shows the words to students.C．It can reduce the dust in the classroom.D．It can save teachers’ time.正确答案：A22．A．Students’ ability to study.B．Students’ ability to do activities.C．Students’ ability to maintain attention.D．Students’ ability to communicate with others.正确答案：C听力原文：(22)A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.(23)Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly. But in 1995, a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “ Pot-in-Pot Preservation” or “ Cooling System”. It uses two round containers made of clay(泥土). A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.(24)Food in the smaller pot is kept from spoiling through a simple evaporation process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving. The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. The invention became popular with farmers in other African countries.(25)Mohammed Bah Abba personally financed the first 5.000 pot-in-pot systems for his own community and five villages nearby. In 2000, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being.22. What is an important factor in food storage? 23.

Their classic pyramid form, wider at the bottom and narrowing all the way up to the top, has been ingrained in the human mind, and scientists have always assumed that the land area in mountain ranges decreases the higher you climb. Until now, that is. B)New research published Monday in Nature Climate Change reveals a surprising discovery that not only changes the way we think about mountains but could also have big implications for how we understand, monitor and protect the organisms that call them home. It turns out mountain ranges don’t just come in the familiar pyramid form—in fact, most of them have a different shape entirely. C)Researchers Morgan Tingley and Paul Elsen used satellite data on mountain ranges from around the globe to analyze how the amount of the land area changed with increasing elevation(海拔). They learned that pyramidal mountain ranges account for just 32 percent of the mountain ranges on Earth. Of the remaining mountain ranges, six percent have an inverse, or upside-down, pyramid form, with the land area increasing toward the top; 23 percent have an hourglass(沙漏)shape, being wider and at the bottom and top and pinched(挤压)in the middle; and 39 percent have a diamond form, with less land areas at the top and bottom and more available in the middle. D)”I did expect that we’d see some patterns that were not this classic pyramid,” says Elsen, lead author and PhD student in Princeton University’s ecology and evolutionary biology department. In fact, Elsen got interested in conducting the study while doing field research in the Himalayas. He noticed that as he hiked to the tops of the mountains, the land area seemed to increase, rather than decrease, at high elevations. Still, he says, “I had no idea that pyramid mountains would be the exception to the rule.”E)It’s hard to tell the true form of a mountain range just by looking at any given mountain peak, since most individual mountains still come to a point at the very top. But mountain ranges are so big, and their topography(地形)so complex, that it would be impossible to observe their true shapes just by looking at them. That’s why the researchers had to analyze satellite data, looking at the total surface area in relation to elevation across the whole mountain range, to complete their study. The way the land area is distributed on a landscape scale—whether the greatest area lies at the top, bottom or in the middle when you take into account all the slopes, ravines and plateaus that make up the mountains—is what determines a mountain range’s designation as a pyramid, inverse pyramid, diamond or hourglass.F)The finding doesn’t just flip our view of mountain topography. More importantly, it changes our understanding of how climate change can affect mountain-dwelling species, the authors say. Organisms that live on mountains are in a particular pickle when it comes to climate change. These species tend to be highly specialized and do best in particular habitats and narrow temperature ranges. As global temperatures rise, the best way to find cooler spots is to move higher up on the mountain. But inpyramidal mountain ranges, which get narrower toward the top, moving higher also means losing the land area. Having less available space can cause populations to shrink and can put them at an increased risk of dying out entirely. G)But Elsen and Tingley’s research shows that the pyramid model doesn’t hold true for all, or even most mountain ranges, meaning space shortages might not always fall where scientists think they do. In hourglass mountains, for example, the most constricted(狭窄的)space will be in the middle of the mountain, rather than at the top. On the other hand, species on diamond mountains will see the widest spaces in the middle. And species on inverse pyramids will enjoy increasing land areas all the way up to the top of the mountain. H)”I think this is critical information that will really inform our understanding of mountain species,”says Robert Guralnick, a biodiversity scientist and curator(馆长)at the University of Florida’s natural history museum, who was not involved with the study. “The models we’ve been using are typically that mountain ranges are narrowing toward the top. “More realistic models and a better understanding of mountain topography can help conservationists make better decisions when monitoring and managing mountain species, the paper’s authors say. “This is absolutely an important study for informing our conservation policy,” Elsen says. Knowing where the land area is likely to be scarce can help conservationists target the right places and the right species. I)In some cases, new knowledge could even indicate that climate change doesn’t threaten a species in quite the way scientists thought. The Himalayan monal, for example, is a colorful bird that lives in the Himalayan mountains, which have the hourglass form. Currently, the bird prefers an elevation that’s right in the middle of the hourglass, says Morgan Tingley, senior author and assistant professor of ecology and evolutionary biology at the University of Connecticut. So space may be pinched for it now, but if warming temperatures force the bird into higher elevations, it will likely enjoy more space as it moves upward. J)On the other hand, a bright little bird called the beautiful nuthatch—which is already classified as a vulnerable species by the International Union for Conservation of Nature—lives just below the pinched part of the hourglass. If it were to flee to higher ground, it would lose the land area. “This current research is showing that there are potentially optimistic futures for some species, and it’s also highlighting these bottleneck zones,” Elsen says. K)The research is also relevant for species that move downslope in response to climate change, chasing the increased precipitation that comes with warmer temperatures. Before now, most scientists might have assumed that any species moving downhill would be able to take advantage of greater and greater land areas as it moved along. Now we know that in certain mountain ranges, these species may actually encounter a shortage in space as they move toward the base of the mountain, and their populations may shrink as a result.37．As for inverse pyramidal mountains, species have wider land areas all the way up.正确答案：G38．The Himalayas have got wider land areas at higher elevations.正确答案：D39．The mountain areas are too large and complex for researchers to observe so that satellites have to be used in order to get exact data.正确答案：E40．Most people have got the same idea about how a mountain looks like, which is a typical pyramid form.正确答案：A41．The more conservationists know about mountain models and topography, the better they can monitor and manage mountain species.正确答案：H42．In pyramidal mountain ranges species that move to a higher and cooler place are faced with the lack of the land area and finally the risk of extinction.正确答案：F43．Except for the pyramid form, mountain ranges have got other forms like the inverse pyramid form, an hourglass shape and a diamond form.正确答案：C44．The finding changes our understanding of how climate change can affect species living in the mountains.正确答案：F45．The current research indicates that there are good opportunities as well as some dangers for some mountain species.正确答案：J46．That scientists used to think that species moving downhill would live in a wider area may not be true according to the current knowledge of different mountain ranges.正确答案：KSection CYou may know the feeling. It’s the late afternoon, and you still haven’t left the house. You’ve spent the last several hours on your phone, scrolling through your Facebook news feed, refreshing Twitter and watching YouTube videos. A smartphone might feel like it’s keeping you connected, but it can also be a way of secluding yourself. Data from a recent study conducted by researchers at Northwestern University’s Feinberg School of Medicine found that the scenario described above—high volume of phone use and a static(静止的)geographic location—could be linked to depression. The study, published in The Journal of Medical Internet Research, also found that depressed people, on average, spend more time on the phone than non-depressed people. “People are likely, when on their phones, to avoid thinking about things that are troubling, painful feelings or difficult relationships,” said David Mohr, one of the study’s senior authors and a professor of behavioral psychology at Northwestern, in a statement. “It’s an avoidance behavior we see in depression.”Mohr also pointed out that depressed people tend to withdraw emotionally and avoid going out—behaviors that are arguably facilitated by the constant entertainment stream available on smartphones. The study’s participants consisted of a mix of people with and without prior depression. They completed a questionnaire describing their symptoms before agreeing to have their phone use monitored for two weeks. Using GPS, the researchers tracked their location and the amount of time they spent on the phone. They were then able to identify which participants were depressed using the aggregated phone data, with 87 percent accuracy. Sohrob Saeb, a research fellow at Northwestern, said in the release that phones could be more reliable for diagnosing depression than traditional methods. In standard industry practice, patients are often asked to describe their symptoms by indicating how sad they are on a scale of 1 to 10. According to Saeb, the release reported, these responses can be rote and unreliable. In contrast, the study found, a smartphone can unobtrusively(不引人注目地)and accurately measure a patient’s daily activity, providing data that could trigger a health care provider to recognize the need for an intervention.47．What is the author’s opinion about using a smartphone?A．It is only a tool to contact people.B．It makes people feel lonely.C．It does great harm to health.D．It keeps people apart from others.正确答案：D48．What can be learned from the study conducted by researchers at Northwestern University?。

Write your essay on Answer Sheet 1.正确答案：The Pros and Cons of Dormitory Life Dormitory life is a new experience for some university students who have never lived far away from their parents before. For example, they must depend on themselves to get up in the morning on time for class and to set aside an appropriate amount of time for study and relaxation. Some people believe there are more advantages about dormitory life. In a dormitory, on the one hand, students have more chances to communicate with and learn from each other. On the other hand, students have a great deal more freedom than they might have at home. They can act according to their own will rather than to that of parents’. But some others disagree. They think dormitory rooms are often small and crowded. This lack of space can limit one’s privacy and make it difficult for students to be engaged in their studies. In general, there are both sunshine and shadow about life in student dormitory. Whether they like it or not, most students have to face the reality of living with others.Part II Listening ComprehensionSection A听力原文：W: I’m a little worried about Jill.

TranslationPart I Writing1．For this part, you are allowed 30 minutes to write an essay commenting on the statement “We can learn more from people at a higher level than us (like teachers) than from people who are at the same level as us.” Do you agree or disagree? You can cite examples to illustrate your viewpoint. You should write at least 120 words but no more than 180 words.正确答案：Learn from the Wise It is said that we can learn from people at a higher level than us, for example teachers, than those who are at the same level as us.I strongly believe that there is a point in such a statement. First, people at a higher level here do not refer to those of mere greater age, seniority or social status. It is the maturity of the soul that measures which kind of people we can learn from and rest upon. Take the story between Aristotle and Alexander the Great as an example. Overbearing as he was as a king, Alexander respected Aristotle, a pagan from another polis, as his teacher. By repeatedly seeking advice from Aristotle, he expanded the presence of his military forces even towards the Asian and African continents. It is the mental support from his teacher that realized his ambition. No one in the world can be perfect. And that is why we should learn from others, especially from those who are wiser, more insightful and more intelligent. Learning from them can make us better improve ourselves.解析：此类题型属于典型的观点论述题。
