We can feel acceleration, an increase in speed. But we notice it for only a short time. For example, we feel it during the takeoff of an airplane. We feel the plane's acceleration because our bodies do not get speed as fast as the plane does. It seems that something is pushing us back against the seat. Actually, our bodies are trying to stay in the same place, while the plane is carrying us forward. Soon the plane reaches a steady speed. Then, because there is no longer any change in speed, the feeling forward motion stops. 8. What lets us know that we are moving？ (13) A．Our body. B．Our senses. C．The speed. D．The plane.

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)

M: I'd be happy to. The piece that broke off was over a thousand square miles in area. More recently and quite alarming to scientists is that a forty-mile crack, some 30 feet wide in places has torn through the ice shelf. W: I understand that the scientific community is quite concerned. What is the significance of these events？ M: Well, some scientists believe that this is a clear sign of global warming. Back in 1978, some American researchers predicted that Antarctica would show early signs of global warming due to the green house effect. W: But couldn't crumbling ice shelves also be a result of the unusual weather Antarctica itself has experienced lately？ M: That's certainly possible, but you'll have to remember that over the past thousands of years, ice shelves have been through a lot of weather changes without breaking up. W: I think most people know that if the ice cap over Antarctica melts, the level of the oceans will rise. What sort of impact will this have？ M: Well, the ice shelves currently insulate the Antarctic continent from wind, which slows down the melting. If the winds cause even a tenth of the continent's ice to melt, the world's oceans could rise as much as 30 feet. What are the speakers mainly discussing？ A．An experiment in Antarctica. B．Part of the Larsen Ice Shelf broke off. C．The formation of the Larsen Ice Shelf. D．An expedition in Antarctica.
