This story is probably apocryphal, but it illustrates well the attitudes of the time. (47) Many people accept Darwin's view of how we came into being that our bodies evolved through the process of natural selection acting on our genes. However, Darwin believed evolution was responsible for far more than just our physical characteristics. He saw it as the major influence in shaping our psychology. In- deed, he predicted that "in the distant future, psychology will be based on a new foundation". (48) To proponents of concepts like free will and personal responsibility, such an idea seems absurd. (49) Their research has revealed increasing evidence that the human mind is made up of innate mechanisms, which control everything from the way we perceive time and space, to how we learn survival techniques and choose mates. (50) Steven Pinker, Professor of Cognitive Science at the Massachusetts Institute of Technology, likens language ability to computer software, "children learn a new word every 90 minutes of their waking life for years, then they have to figure out how to string them together using a kind of mental computer program. The essence of human language is the ability to convey new ideas by putting words together in different combinations. Since we all have this language 'software' in our minds, we can figure out what others are saying by the meanings of the words and the order in which they are arranged." A. Today, we are more comfortable with out past. B. "And, if it is true, let us hope it does not become public knowledge." C. But a growing number of scientists are questioning the extent to which our behavior. is controlled by our culture. D. Many people are calling for controls on cloning immedicte1y before the practice is abused. E. The foundation was, of course, his theory of evolution. F. Nowhere is this more obvious than our innate ability to learn languages. (46)

Jercy Page was ninety 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 Jercy Page sleeping. Actually, he did not even own a bed. He never needed one. The only rest that Jercy Page got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They asked him many questions, hoping to find an answer. They found only one answer that might explain his condition. Page 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. The main idea of this passage is that ______. A．large numbers of people do not need sleep B．a person was found who actually didn't need any sleep C．everyone needs some sleep to stay alive D．people can live longer by trying not to sleep

When it comes to success, luck can mean being in the right place to meet someone, or having the right skills to get a job done. It might mean turning down an offer and then having a better offer come along. Nothing can replace hard work, but working hard also means you're preparing yourself opportunity. Opportunity very often depends on luck. How many of the great inventions and discoveries came about through a lucky mistake or a lucky chance？ One of the biggest lucky mistakes in history is Columbus' so-called discovery of America. He enriched his sponsors and changed history, but he was really looking for India. However, Columbus' chance discovery wasn't pure luck. It was backed up by years of studying and calculating. He worked hard to prove his theory that the world was round. People who work hard help make their own luck by being ready opportunity knocks. When it comes to success, hard work and luck are always hand in hand. (30) A．Hard work is the most important thing for one's success. B．Hard work may invite good luck. C．Good luck plays an important role in one's success. D．Success has nothing to do with luck.
