在一个利益多元化、价值观纷呈的时代，不是所有的国家工程都能赢得国人的齐声叫好，而国家在科技方面的大手笔，比如探月工程，却能赢得普遍的祝福声。从文化生活的角度看，其原因是（）
①文化越来越成为民族凝聚力和创造力的重要源泉
②政府采取切实措施改变现代经济的总体格局
③说明文化与经济、政治相互交融、相互影响
④彰显了中华文化的包容性和独特性
A.②④
B.①③
C.③④
D.①②
参考答案：B
解析：
“探月工程，却能赢得普遍的祝福声”是由于文化与综合国力的关系、文化与经济的关系，题肢①③符合题意。政府采取切实措施改变现代经济的总体格局不是文化生活的角度，故排除题肢②；材料没有体现中华文化的包容性和独特性，题肢④与题意无关；答案选B。
考点：文化与经济、政治，文化与综合国力
Passage Four
| Global climate change, often seen as a process stretching over thousands of years, could in fact occur abruptly and unexpectedly-quickly pushing up temperatures by as much as 18 degrees Fahrenheit and wreaking havoc(大破坏，浩劫) on human society, scientists warned on Wednesday. "Climate change is not always smooth. Sometimes it is abrupt," said Richard Alley, a climate expert at Pennsylvania State University and lead author of a new National Academy of Sciences report on the threat of rapid climatic shifts. "If you have a very large, abrupt change, a lot of people and a lot of ecosystems are going to notice," he said．"The bigger and faster it is, the harder it will be to deal with." The new National Academy of Sciences report, released this week, warns that gradual global warming coupled with other human impacts on the environment could "trip the switch" for sudden climate change. At the American Geophysical Union meeting on Wednesday, Alley and other environmental scientists said the geological evidence indicated that such rapid climate shifts had occurred frequently in the past—moving temperatures drastically in the space of just a few decades. "This can happen in less than a human generation, and then it will persist for thousands of years," said David Battisti, an atmospheric scientist at the University of Washington. The most immediate dangers posed by abrupt climate change range are devastating droughts and floods which could seriously affect both water supply and agriculture across vast stretches of the planet. Longer term impacts could include changes in the basic systems which determine regional global temperatures. Scientists believe that the Gulf Stream, a current (水流) of warm Atlantic water which now keeps much of Northern Europe temperate, could theoretically reverse direction if enough cool fresh water runs into the north Atlantic from melting ice, a change that would quickly impact European weather. |
According to the passage, in the long run, abrupt climate change______.
A．could make the Gulf Stream warmer
B．could melt much ice on Earth
C．could submerge the whole European continent
D．could evaporate all fresh water on Earth
