第5题：
Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.
Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.
Last year 270 whales died along the whales'migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber(fat)on them.
Twenty years ago,the gray whale was listed as an endangered species.
Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply,a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.
Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.
65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases,but it may be over-population．
About how many more whales have been sighted in the San Francisco Bay this year compared to last year?A.Twice as man
B.Three times as man
C.Half as man
D.About the sam答案：B解析：由最后一段可知。今年在旧金山海湾地区看到了65只鲸，去年是17只。所以今年大约是去年的三倍。 -

第9题：
问答题Scientific and technological advances have improved our daily lives. However, in many fields scientists cannot solve the problems they have created themselves. Do you agree or disagree with this opinion? Give your reasons. Write a composition of about 400 words on this topic.正确答案：
Scientific and technological advances have, admittedly, improved people's daily lives and dramatically changed the way people live. People nowadays actually owe a great debt to the inventors who have pushed forward the development of science and technology. However, I am a strong believer in the claim that scientists in many fields cannot solve the problems they have created themselves, for the following reasons :
The creation of a new scientific and technological product is a purely academic matter, but its application may be affected by political, historical and military factors. For example, the original purpose of cloning was simply scientific—to change undesirable genes at the embryo stage, and to alleviate pain and illness of the patients. However, some people with ulterior motives may take advantage of this technique to clone human genes. This is sure to cause serious moral uncertainty and chaos for the human race. The inventors of cloning might have never imagined that the technology is now used for dishonorable purposes, and they can only rely on the government to prohibit human cloning by enforcing strict laws.
Sometimes it is impossible for researchers and scientists to predict the future application of the product they are working on. Atomic energy is a case in point. Its study and research are conducted with the aim of saving the world's limited energy resources and optimizing the use of current energy sources, such as water. Yet people are saddened by the news that atomic technology is used to manufacture dangerous weapons for the purpose of threatening or even destroying other countries and innocent people. For example, to retaliate Japan's attack on its Pearl Harbour, the United States dropped two atomic bombs in Hiroshima and Nagasaki, causing huge mortality and destruction, which were absolutely never dreamed by the scientists who invented the weapon. And once it was put into military use, the inventors could do nothing to change the fearful result.
In conclusion, scientists in many fields find themselves helpless when it comes to controlling the application of the technology they have labored so hard to produce and to solve the problems they have created.解析：
针对“科学家无法解决一些科技进步带来的问题”这一观点，范文作者在第一段末表示赞同。第二、三段具体解释了赞同的原因。首先，科技的应用受到政治、历史和军事因素的影响。其次，科学家不能完全预测产品的未来用途。其中恰当地运用了实例支持分论点。结尾段简洁地总结了中心思想。 -

单选题The author suggests which of the following about art historians?AThey do not believe that illusionist tricks have become trivial.
BThey generally spend little time studying contemporary artists.
CThey have not given enough consideration to how the representation of nature has become commonplace.
DThey generally tend to argue about theories rather than address substantive issues.
正确答案： C解析：
题目中提到art historians，可定位于文章中：The very reason why the representation of nature can now be considered something commonplace should be of the greatest interest to art historians，即那些现在被认为是司空见惯的东西本应该是艺术历史学家最感兴趣的内容。由此推断，事实上，艺术历史学家们并没有给予足够的关注。 -
