第2题：
The journal Science is adding an extra round of statistical checks to its peer-review process,editor-in-chief Marcia McNutt announced today.The policy follows similar efforts from other journals,after widespread concern that basic mistakes in data analysis are contributing to the irreproducibility of many published research findings.
“Readers must have confidence in the conclusions published in our journal,”writes McNutt in an editorial.Working with the American Statistical Association,the journal has appointed seven experts to a statistics board of reviewing editors（SBoRE）.Manuscript will be flagged up for additional scrutiny by the journal’s internal editors,or by its existing Board of Reviewing Editors or by outside peer reviewers.The SBoRE panel will then find external statisticians to review these manuscripts.
Asked whether any particular papers had impelled the change,McNutt said:“The creation of the‘statistics board’was motivated by concerns broadly with the application of statistics and data analysis in scientific research and is part of?Science’s overall drive to increase reproducibility in the research we publish.”
Giovanni Parmigiani,a biostatistician at the Harvard School of Public Health,a member of the SBoRE group.He says he expects the board to“play primarily an advisory role.”He agreed to join because he“found the foresight behind the establishment of the SBoRE to be novel,unique and likely to have a lasting impact.This impact will not only be through the publications in Science itself,but hopefully through a larger group of publishing places that may want to model their approach after Science.”
John Ioannidis,a physician who studies research methodology,says that the policy is“a most welcome step forward”and“long overdue.”“Most journals are weak in statistical review,and this damages the quality of what they publish.I think that,for the majority of scientific papers nowadays,statistical review is more essential than expert review,”he says.But he noted that biomedical journals such as Annals of Internal Medicine,the Journal of the American Medical Association and The Lancet pay strong attention to statistical review.
Professional scientists are expected to know how to analyze data,but statistical errors are alarmingly common in published research,according to David Vaux,a cell biologist.Researchers should improve their standards,he wrote in 2012,but journals should also take a tougher line,“engaging reviewers who are statistically literate and editors who can verify the process”.Vaux says that Science’s idea to pass some papers to statisticians“has some merit,but a weakness is that it relies on the board of reviewing editors to identify‘the papers that need scrutiny’in the first place”.
It can be learned from Paragraph 1 thatA.Science intends to simplify their peer-review process.
B.journals are strengthening their statistical checks.
C.few journals are blamed for mistakes in data analysis.
D.lack of data analysis is common in research projects.答案：B解析：根据题干直接定位到第一段。解题关键在于第二句The policy follows similar efforts from other journals（该政策效仿了其他杂志类似的做法），the policy指第一句The journalScience is adding an extra round of statistical checks to its peer-review process,（《科学》杂志把统计检查额外添加到它的同行评审过程中），由此可直接推断出正确答案为选项B journals -

【范文】
The More I Learn, the More Ignorant I Find Myself to Be As soon as I was enrolled in college, I felt a big burden off my mind. So did my classmates. We just wanted to relax. But at our first English lesson on how to improve our study the teacher told us, “There is no end of learning. The more you learn, the more ignorant you will find yourself to be. The only way you can do is to work hard to learn more.”
The teacher’s words awaken me and remind me of the ignorant few who claim to have all of the answers to man and life but know less than you or I, and who, with their hands held up high, offer everything you may have wanted to know about life itself, but when pushed and pried knowing nothing but what they are told. Now I am a postgraduate, and life has taught me too many harsh lessons. The more I learn and experience, the more I realize how little I know. Therefore, bearing in mind the motto that there is no end of learning, I keep on my studies. I do not only learn from the books, but also from experiences, as practice makes perfect.
For all of my efforts, I am fully aware how far I am away from the sea of knowledge. The more I learn, the more ignorant I find myself to be and the more I feel the need to learn. Art is long, and life is short.解析： 暂无解析 -

问答题Task II(20 points) Directions:Write on the topic given below in no less than about 160 words on the Answer Sheet. In your essay, you should first outline your ideas, and then give examples. Topic: What, in your opinion, is the best way to keep fit and healthy?正确答案：
The Best Way to Keep Fit and Healthy A fit and healthy body is the base of wealth and wisdom. Good health enables us to enjoy our life and achieve what we hope for in our career. On the contrary, poor health tends to deprive us of our interest in everything around us. Only by keeping ourselves healthy and strong can we feel energetic and vigorous in studying, working and living a happy life. People aware of the health problems bring up with a lot of ways to keep fit and healthy. However, the best way to keep fit and healthy is to exercise more and eat properly.
Firstly, physical exercise is very crucial in order to keep fit and healthy. In taking part in out-door sports, we are closer to the nature and can take in fresh air. The beauty of nature will keep us clear-headed, which is essential to our health. Secondly, proper nutrition is important for our body, so we have to keep a balanced diet and maintain a regular eating habit. It is important for us to take more fruits and vegetables because they provide vitamins and they help in the process of digestion. At the same time, we should avoid eating too much food rich in sugar and fat.
In conclusion, if we stick to the proper ways of exercise more and eat properly, we’ll lead a healthy life and become as fit as a fiddle.

You have twenty-five minutes to write an essay on the topic assigned below.Practice 1 Think carefully about the issue presented in the following excerpt and the assignment below. The liberally educated person is one who is able to resist the easy and preferred answers, not because he is obstinate but because he knows others worthy of Consideration. —Allan Bloom Assignment: What is one important easy and preferred answer that we should resist? That is, what dangerous misconception do people commonly hold? Write an essay in which you answer this question and support your position logically with examples from literature, the arts, history, politics, science and technology, current events, or your experience or observation.正确答案： 【参考范文】
One of the most dangerous misconceptions that people hold today is the idea that our enemies are fundamentally different from us. It is easy, to a certain extent, to understand how such a belief comes about. Most human societies must kill in order to survive, but must at the same time prohibit particular kinds of killing. Throughout our history, humans have been meat-eaters, and so must kill and eat animals in order to thrive (the minority of vegetarians notwithstanding). Also, societies must often defend themselves against violent enemies, necessitating the occasional use of deadly force. On the other hand, civilized societies must prohibit most killing within their own ranks, so that their populations do not die out or suffer needlessly.
So how do humans deal with this dichotomy: the need to kill, at least occasionally, to survive, and the need to prohibit killing within its ranks? Simply, humans have developed the concepts of us and them. It is okay to kill and eat animals because they do not have the value of humans. Perhaps, too, a society may justify the killing of animals by adopting a belief system that says that animals are gifts to humans from a divine being or beings.
In much the same way, humans are inclined to put their enemies in the category of other, that is, less than human, or to believe that a divine being has given them permission to kill those enemies. Paradoxically, those religious systems are also very likely to have severe restrictions against killing other human beings. In practice, most cultures regard these as restrictions merely against killing their own kind. However, this type of thinking is counterproductive to the goal of building more just and functional societies. If one society can easily categorize another as an enemy and thereby reduce its foes to the status of animal, then the concept of universal human rights is abolished.
We see the dangers inherent in denying the humanity of our enemies in the United States today. Although the American Constitution champions the concept of inalienable rights that are due to all human beings, the United States Senate is actively engaged in undermining those rights. The right of habeas corpus, that is, the right of a person in custody to seek a hearing to determine whether or not he or she is being held justly, is a cornerstone of the United States Constitution. It is regarded as a fundamental element of a just society. Yet the Senate is seeking to eliminate that right for foreign detainees captured in the war on terror. In other words, the mere suspicion of terrorism—not proof, but suspicion—is evidently reason enough to reduce a human being to the status of an animal. This heinous distinction of us versus them will surely have dire consequences for the United States, who will rightfully be seen as being grossly hypocritical on the matter of human rights.
Even beyond the trampling of human rights, the us versus them distinction is not even as useful in wartime as it may seem at first glance, because to defeat our enemy, we must understand our enemy. If we begin with the assumption that your enemy lacks human intelligence, desires and motivations, then we risk severely underestimating his ability. Therefore, if the United States continues down this dangerous path, it runs the risk of losing not only the moral war but the actual war.解析： 暂无解析 -

问答题Practice 6Directions: For this part, you are allowed 30 minutes to write an essay commenting on the topic “Can Money Buy Happiness?” You can cite examples to illustrate your point. You should write at least 150 words but no more than 200 words.正确答案：
【范文】
Can Money Buy Happiness? I have once seen a caricature that depicted an ironic picture: a man who is overloaded with a pretty large piece of gold is making every effort to creep forward. However, there is much to say about it. It gives a vivid expression to a serious topic—Can money buy happiness?
Money means wealth—social wealth as well as personal wealth. Making money is creating wealth. The more money you have, the wealthier you are. To increase wealth is what a person desires and what society needs. A person’s desire can never be satisfied and social progress has no ending. Therefore, making money is one of essential activities that identify a person’s existence.
Happiness is referred to as enjoyable experiences that people are feeling. To some extent, enjoyable experiences result from a person’s mental satisfaction. People can never get satisfied with making money, so money is something distant from happiness. Although the man mentioned above is possessed of much money, he is suffering from the weight of gold. It is not exceptional that some millionaires are not happy at all in life. Indeed, money can buy wealth, but it cannot buy happiness if inappropriately used.
Nevertheless money is not in contradiction to happiness when making money is regarded as a means to attain a definite goal. In a word, more attention should be focused on orientation of life when it comes to the subject—Can money buy happiness?解析： 暂无解析 -

第14题：
资料：For the development of Crunchy Nut （a product）,K company has used various methods of primary data collection. Primary market data may involve qualitative research or quantitative research. Qualitative data is connected more about opinions, feelings and attitudes. Quantitative data is in numerical form and is usually gathered from a large sample of respondents.
Qualitative research establishes a conversation with consumers. It prompts consumer reaction to, for example, a new product idea and helps researchers understand what they think of it, how it makes them feel, why they find it interesting or not.
Qualitative research may be obtained through focus groups, where a moderator captures feedback from a group of six or seven consumers to the ideas shown to them. Those ideas may take the format of drawings or having new food prototypes to taste. Quantitative research may use questionnaires administered to large numbers of respondents. This allows statistical analysis. It may involve the use of scales, so numbers get associated with a particular meaning-for example, on an evaluation scale of 1 to 7, where 1 means very poor and 7 means excellent. Crucially those numbers need to be interpreted to enable the business to understand the consumers' overall response.

【范文】
It Pays to Be Honest Nowadays, some people hold the opinion that those honest people are fools whose ways of coping with the outside world cannot work. They believe that only those who stop at nothing to get what one wants can subsist and succeed in our society, which features severe competitions. However, in my opinion, no matter what we do, to be honest is the best policy for all of us. If we stick to the principle of honesty, we will benefit and achieve for sure a lot from it, which will promote us to succeed in the future.
Honesty can help us win trust and respect from others, which no doubt will do good to us. In university, for example, to students, honesty is of great importance and of great value to their academic research or cooperation with their supervisors. To tell the truth, it requires a good deal of time and patience to do the research honestly. Nevertheless, we will learn a lot from our hard work and will feel fulfilled as well. At the same time, our efforts will be recognized by our supervisors. In this way our honesty will not only bring us improvement in studies, but also will lead to mutual trust and respect between students and supervisors.
In conclusion, honesty is the best policy for all of us. Whatever we do we must uphold the principle of honesty, because it not only can win trust and respect from others for us, but also bring us more opportunities in the future.解析： 暂无解析 -

【范文】
Living in a Big City or a Small Town With ample supply of medical resources, convenient public transportation, various entertainment activities and normally higher salary than that of elsewhere, big cities are rather preferable to some people.
However, big cities have their own disadvantages which make them inferior to small towns. Air pollution and noise pollution pose a threat to citizen’s health. Traffic congestions will also fill big cities with frustrated drivers, which add peril to driving. Therefore, some people choose to live in a small town.
Small towns, though not so developed and prosperous as big cities, are often peaceful as there are not many people and heavy traffic. People do not have to travel a long distance to work. In a small town, there is relatively more space for green belts, parks or gardens where people, can enjoy the fresh air. Unlike people living in big cities, those living in a small town will have greater chances of making acquaintances of one another in the neighborhood by leisurely exchanging greetings since they do not have to hustle and bustle all around.
I would choose to live in a small town. I love to spend my time walking in a place with more space, fresh air and greenness.解析： 暂无解析 -

【范文】
My Idea of Professional Ethics for a Scientist There is no denying that a distinguished scientist should not only be learned and creative but also have good professional ethics for the good of both society and the scientist himself. But what are good professional ethics for a scientist?
In my opinion, a scientist should possess the following qualities. First of all, an eminent scientist should make sure that his knowledge is used to bring benefits to the general public rather than to make his personal gains. He should devote himself to the advancement of technology, with the aim of raising the living standards of people and making our world a better place to live in. Secondly, as a respectable scientist, he should be on good terms with other scientists. Cooperation and mutual trust between scientists are very critical for scientific achievements. Thirdly, a good scientist should be honest and respect the work of others. Never should he copy from others or falsify research findings. Last but not the least, a scientist should be a responsible person. He should not make any hasty decisions. Once a decision is made he should shoulder its consequence.
In a word, an excellent scientist should have good professional ethics to win the respect of the people and contribute more to people’s benefits.解析： 暂无解析
