For the most part, schools are designed to produce people who fit into society, not people who set out to change it. However, schools, particularly universities, may not only spread culture; they may add to the cultural heritage(遺產(chǎn)). Today American society places a good deal of emphasis on the development of new knowledge, especially in the physical and biological sciences , medicine, and engineering. In the recent years, the nation’s leading universities have increasingly become research centers.
An emphasis（強調(diào)）on research has led universities to judge professors not by abilities as teachers, but as researcher. promotions(提升), salary increases , and other benefits have long been dependent on research and publication. However, the most important is no longer publishing. To be successful these days, professors have to bring in money provided by government and private industry. Critics claim that academic(學(xué)術(shù)) success is most likely to come to those who have learned to“ignore”their teaching duties to pursue research activities. Defenders say that even when students themselves are not involved in research projects they benefit from such an emphasis on research.
Major research universities like the Massachustts Institute of Technology have also cooperated with industrial companies to develop technology and products with commercial potential(潛能).With university-industry ties continuing to grow, debate（辯論）has increased about the consequences for basic science, academic openness, the control of information, the direction of research, and the influence on students.
1. According to the passage, which of the following is NOT emphasized by today’s American society?
A. Physical science.          B. Biological science.
C. Engineering.            D. Computer science.
2. In the present standard, a successful professor is one who can____.
A. teach well             
B. get financial support for research
C. get the highest salary    
D. have many publications
3. Supporters of the present emphasis on research argue that_____.
A. it involves more students in it.
B. it does good to students anyway.
C. it has a direct good effect on teaching
D. it earns a lot of money for a university
4. The author seems to be_____ the move of emphasis to research.
A. totally against   B. sorry to see      C. in favor of    D. neutral (中立) about

It’s true that quite a few most respected scientific authorities have confirmed that the world is becoming hotter and hotter. There’s also strong evidence that humans are contributing to the warming. Countless recent reports have proved the same thing. For instance, a 2010 summary about the climate science by the Royal Society noted that: “The global warming over the last half-century has been caused mainly by human activity.”

You may not believe that humans could change the planet’s climate, but the basic science is well understood. Each year, billions of tons of greenhouse gases are released into the atmosphere because of human activity. As has been known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible (看不見的) blanket.

Of course, the earth’s climate has always been changing due to “natural” factors such as volcanic eruption or changes in solar, or cycles concerning the Earth’s going around the sun. According to the scientific research, however, the warming observed by now matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.

Even if scientists did discover another reasonable explanation for the warming recorded so far, that would give birth to a difficult question. As Robert Henson puts it: “If some newly discovered factor is to blame for the climate change, then why aren’t carbon dioxide and the other greenhouse gases producing the warming that basic physics tells us they should be?”

The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.
