Write a composition of about 200 words on the topic “Publish or Perish” Your composition should be based on the information given below:Many universities require each graduate student to have at least one paper published before getting the master’s degree. They say this is a good way to evaluate the graduate students. What do you think about this?

中国可持续发展依赖的有限自然资源正在锐减。一方面是生产规模在不断扩大，消耗更多的能源；另一方面是缺少能高效利用能源的生产设备。这迫使我们思考如何为后人留下足够的环境空间以使他们实现他们的愿望。

In this book, we offer advice that we hope will seem reasonable and worth serious consideration. But as any experienced writer knows, there are occasions when even the best advice may not apply. The demands of writing for different audiences, with different purposes, on different subjects, at different levels of formality are so varied that they cannot begin to be anticipated in a book like this, and we recognize that what is appropriate for one piece of writing may not be appropriate for another. In most cases, you will have to avoid ambiguity at all costs so as not to leave your words open to misinterpretation.

The patient needed a spinal tap, and a senior attending physician asked a medical resident whether a preparatory blood test had been checked. The medical student was stunned to hear him answer in the affirmative, because she was quite certain it had not been checked.(1) Well, almost certain.Doctors in training sometimes confront situations in which they worry that their supervising physicians are making mistakes or bending the truth. (2) Yet even though such acts can jeopardize patients, the inclination and ability of young doctors to speak up is hampered by the hierarchies in teaching hospitals.On the top were the senior physicians who made rounds on the wards once or twice daily. Next were the overworked residents, who essentially lived in the hospital while training. (3) Last were the medical students who were most assuredly at the bottom of the heap.The student whose resident seemingly lied to the attending physician about the blood test did not speak up. The resident was a good doctor, she said, and so she had given him the benefit of the doubt. And, she added, both the resident and the attending physician would be grading her.What should a medical student do in such a situation? One possibility is to take the matter up with a more senior doctor. Or the student might go directly to the patient or family, telling them that the physicians have a genuine disagreement and that they deserve to know about it.These options seem logical on paper. As the ethicist James Dwyer has written in The Hastings Center Report, “The practice of always keeping quiet is a failure of caring.” (4) But in the real world, it may be extremely difficult to go up the chain of command.Fortunately, medical educators are increasingly recognizing the dilemmas that doctors in training confront when they witness behavior that makes them uncomfortable. (5) Students and residents are now expected to provide routine feedback—positive and negative—about their supervising physicians at the close of their rotation.Of course, physicians and students need to be educated about how to give feedback in professional and non-confrontational ways. Medical educators are only now beginning to teach this skill. Still, it will be hard to change the unfortunate perception that constructive feedback, even for a patient’s benefit, is whistle-blowing.

Trees are good. Good enough to hug. Planting trees will make the world cooler than it would otherwise be. This is the subject of a newly published study by Govindasamy Bala, of the Lawrence Livermore National Laboratory, in California, and his colleagues. Dr Bala has found, rather counter-intuitively, that removing all of the world’s trees might actually cool the planet down.The reason for this is that trees affect the world’s temperature by means other than the carbon they take in. For instance forests remain quite a dark shade even after a snowstorm. They are certainly darker than grasslands, and thus they can absorb more of the sun’s heat than vegetation which might otherwise cover the same stretch of land. That warms things up.Dr Bala and his colleagues took such effects into account using a computer model called the Integrated Climate and Carbon Model. Unlike most climate-change models, which calculate how the Earth should absorb and radiate heat in response to a list of greenhouse-gas concentrations, this one has many subsections that represent how the carbon cycle works, and how it influences the climate.Overall, Dr Bala’s model suggests that complete deforestation would cause an additional 1.3℃ temperature rise compared with business as usual because of the higher carbon–dioxide levels that would result. However, the additional reflectivity of the planet would cause 1.6℃ of cooling. A treeless world would thus be 0.3℃ cooler than otherwise.No one, of course, would consider chopping down the world’s forests to keep the planet cool. But having made their point, Dr Bala and his colleagues then went on to look at forest growth and loss at different latitudes. Planting trees in convenient places such as Europe and North America may actually be counterproductive. In Russia and Canada, cutting trees down led mostly to local cooling. The carbon dioxide this released into the atmosphere, though, warmed the world all over. Around the equator, by contrast, warming acted locally (as well as globally), so a tropical country would experience warming created by cutting down trees. The results follow increasing criticism from climate scientists of the benefits of forestry schemes to offset carbon emissions. Planting trees to neutralize carbon emissions has become a big business: £60m worth of trees have been bought this year, up from £20m in 2005. By 2010 the market is expected to reach f300m.1.

We’re talking about money here, and the things you buy with it—and about what attitude we should take to spending.Across most of history and in most cultures, there has been a general agreement that we should work hard, save for the future and spend no more than we can afford. It’s nice to have a comfortable life right now, but it is best to think of the future. Yet economists have long known that things don’t work out that way. They point to an idea called the “paradox of thrift”. Imagine you are the owner of a big business making consumer goods. You want your own staff to work hard and save their money. That way, you don’t have to pay them as much. But you want everybody else to spend all the money they can. That way you make bigger profits.It’s a problem on a global scale. Many people in the UK and the United States are worried about levels of personal debt. Yet if people suddenly stopped buying things and started paying back what they owe to credit card companies, all the economies of the Western world would collapse. The banks would be happy, but everybody else would be in trouble.Traditionally, economists have believed that spending money is about making rational choices. People buy things to make their life better in some way. But in recent years, they have noticed that people often do not actually behave in that way. We all know people who take pleasure in buying useless things. And there are many people around who won’t buy things that they need.In a recent series of experiments, scientists at Stanford University in the US confirmed something that many people have long suspected. People spend money because the act of buying gives them pleasure. And they refuse to spend when it causes them pain. The scientists discovered that different areas of the brain that anticipate pleasure and pain become more active when we are making a decision to buy things. People who spend a lot have their pleasure centers stimulated. People who like to save find buying things painful.If you think you really want that product because it’s beautiful or useful, you are wrong, say the scientists. The desire to buy something is a product of the reaction between chemicals released by different parts of the brain when the eyes see a product.1.

Global warming poses a threat to the earth, but humans can probably ease the climate threats brought on by rising levels of carbon dioxide in the atmosphere, global climate specialist Richard Alley told an audience at the University of Vermont, Alley said his research in Greenland suggested that subtle changes in atmospheric patterns leave parts of the globe susceptible to abrupt and dramatic climate shifts that can last decades or centuries.Almost all scientists agree that increasing levels of carbon dioxide in the atmosphere created as humans burn fossil fuel is warming the planet. How to respond to the warming is a matter of intense political, scientific and economic debate worldwide.Alley said he was upbeat about global warming because enough clever people existed in the world to find other reliable energy sources besides fossil fuels. He said people can get rich finding marketable alternatives to fossil fuel. “Wouldn’t it be useful if the United States were to have a piece of the action. Wouldn’t it be useful if some bright students from University of Vermont were to have a piece of the action,” Alley said.Alley said that Europe and parts of eastern North America could in a matter of a few years revert to a cold, windy region, like the weather in Siberia. Such shifts have occurred frequently over the millennia, Alley’s research shows. A gradual change in atmospheric temperature, such as global warming, could push the climate to a threshold where such a shift suddenly occurs, he said.Alley told his audience of about 200 people in a University of Vermont lecture hall Wednesday evening that he couldn’t predict if, when or where sudden shifts toward cold, heat, drought or water could occur under global warming, but it is something everyone should consider.“This is not the biggest problem in the world. The biggest problem in the world is getting along with each other. But it’s part of that because we’re not going to get along with each other if we’re not getting along with the planet,” Alley said.1.

A report published recently brings bad news about air pollution. It suggests that it could be as damaging to our health as exposure to the radiation from the 1986 Ukraine nuclear power disaster. The report was published by the UK Royal Commission on Environmental Pollution. But what can city people do to reduce exposure to air pollution? Quite a lot, it turns out.Avoid walking in busy streets. Choose side streets and parks instead. Pollution levels can fall a considerable amount just by moving a few meters away from the main pollution source—exhaust fumes (烟气). Also don’t walk behind smokers. Walk on the windward side of the street where exposure to pollutants can be 50 percent less than on the downwind side.Sitting on the driver’s side of a bus can increase your exposure by 10 percent, compared with sitting on the side nearest the pavement. Sitting upstairs on a double-decker can reduce exposure. It is difficult to say whether traveling on an underground train is better or worse than taking the bus. Air pollution on underground trains tends to be, less toxic than that at street level, because underground pollution is mostly made up of tiny iron particles thrown up by wheels hitting the rails. But diesel and petrol fumes have a mixture of pollutants.When you are crossing a road, stand well back from the curb while you wait for the light to change. Every meter really does count when you are close to traffic. As the traffic begins to move, fumes can be reduced in just a few seconds. So holding your breath for just a moment can make a difference, even though it might sound silly.There are large sudden pollution increases during rush hours. Pollution levels fall during nighttime. The time of year also makes a big difference. Pollution levels tend to be at their lowest during spring and autumn when winds are freshest. Extreme cold or hot weather has a trapping effect and tends to cause a build-up of pollutants.1. What is the passage mainly about?2. According to the report, air pollution in big cities（）.3. When you walk in a busy street, you should walk on the side（）.4. If you take a bus in a big city in China, you should sit（）.5. It is implied in the passage that（）.

Harvard University’s under-graduate education is being reformed so that it includes some time spent outside the US and more science courses, the US Cable News Network (CNN) has reported. For the first time in 30 years, Harvard is（1）its under-graduate curriculum. William Kirby, dean of the faculty of arts and sciences, said this（2）what many people had said that Harvard’s curriculum did not provide enough choice and encourage premature specialization.“Harvard needs to（3）its education for a world where global connections, cross disciplinary research, and science in general are ever more important,” said Kirby.Particularly（4）is the idea that students need to spend time overseas, either in a traditional study-abroad program or over a summer, perhaps doing an internship or research.Students can either find the program themselves or（5）some exchange programs offered by the university.“（6）studying Chinese history without leaving the university, students interested in the subject should be spending a semester at a university in China.”It was also recommended that Harvard（7）its required “core curriculum”. The core curriculum was an effort created in 1978 to broaden education by requiring students to choose from a list of courses in several areas of study. Classes often focused on a highly（8）topic and emphasized “ways of knowing”.Under a new plan, the curriculum would be replaced with a set of（9）“Harvard College Courses”, emphasizing knowledge over methodology and（10）wider territory. A life sciences course, for example, might combine molecular and evolutionary biology and psychology, rather than focusing on one of those, said Benedict Gross, Harvard College dean.
