2018-2019年度高二期末考试卷 英 语 第一部分阅读理解 第一节 (共15小题;每小题3分,满分45分) 阅读下列短文,从每题所给的A、B、C、D四个选项中，选出最佳答案。 A Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate (交际) with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell--a signal (信号) causing its neighbors to change the chemistry of their own leaves and make them less tasty. Communication, of course, doesn’t need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So why shouldn’t trees have ways of sending message? 1．It can be concluded from the passage that caterpillars do not feed on leaves that _____.

That's what all doctors thought, until they heard about Al Herpin. Al Herpin, it was said, never slept. Could this be true ? The doctors decided to see this strange man themselves. Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day. They never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one. The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They found only one answer that might explain his condition. Herpin remembered some talk about his mother having been injured several days before he was born. But that was all. Was this the real reason ? No one could be sure. Herpin died at the age of 94. 4．The main idea of this passage is that _____. A．a person was found who actually didn't need any sleep B．large numbers of people do not need sleep C．everyone needs some sleep to stay alive D．people can live longer by trying not to sleep 5．The ... ...
