How to Get on with Your FriendCScience is a major topic in our culture. Since it touches almost every field of our life, educated people need at least some knowledge with its structure and operation. They should also have an understanding of the scientific subculture in which scientists live and the kinds of people they are. An understanding of general characteristics of science as well as specific scientific ideas is easier to obtain if one knows something about the things that excite and discourage the scientist. This book is written for the person whose knowledge with science is not complete; for the person who has been presented with science as a musty（发霉的）storehouse of dried facts; for the person who sees the chief objective of science as the production of tricks; and for the person who views the scientists as some sort of magician. The book can be used to add to a course in any science, to come with any course that attempts to give an understanding of the modern world, or simply to provide a better understanding of science. We hope this book will lead readers to a broader view on scientific attitudes and a more realistic view of what science is, who scientists are, and what they do. It will give them an idea and understanding of the relationship between science and our culture and an appreciation of the roles science may play in our culture. Besides, readers may learn to appreciate the relationship between scientific views and some of the values and philosophies（哲学）that are deep in our culture.obvious in all parts of society, as more women enter traditionally male-controlled fields and make influential contributions.We have also tried to make the book entertaining as well as informative. Our method is usually informal. We feel, as do many other scientists, that we shouldnt take ourselves too seriously. As the reader may observe, we see science as a delightful pastime rather than as a cruel and unpleasant way to earn a living. 43.

Talks went smoothly but differences remained. So Martin Bayer himself, the CEO of the German Company, decided to come to Moscow to head the talks. Besides caring about his business, the CEO wanted to go to Russia to hunt bears. Martin Bayer was one of the greatest hunters of our time (and the Russians knew about it). He went to the Sahara more than hundred times and hunted lions, crocodiles; he hunted polar bears in the North Pole and tigers in the rain forests of India. But he had never hunted Russian bears. So the Russians decided to organize a bear hunt for Mr. Bayer to sweeten the talks. This wasnt a simple task. Some people in the west still believe that bears may be found and seen everywhere in Russian cities just like squirrels may be seen in our back yards. This is not true. The closest place one may find bears in the wild is maybe 2,500 miles away from Moscow. However, a solution was quickly found. The Russian businessmen went to Moscow Circus（马戏团）and for $2,000 bought a very old bear. This bear used to amuse and amaze audiences in many countries for 30 years, but got and looked too old, and was retired. “Be careful, the Russian bears are very dangerous, and frightening,” they told to Mr. Bayer. “If compared to the Russian bears, your African lions are nothing more than harmless cats.” The bear was brought to a forest 50 miles from Moscow and was left there. Mr. Bayer was told that bears were plentiful in that forest and that many cattle and even people had been eaten in the surrounding villages. Mr. Bayer was excited and ready to hunt. This could become the most successful part of his extraordinary hunting experience. The next moment Mr. Bayer saw a bear in a helmet driving on a motorcycle through the forest in front of him. The bear had a happy expression on his face, as he was doing something he had been doing in the circus for 30 years: circling on a motorcycle! Mr. Bayer lives in a private mental institution near Hamburg happily ever after. The equipment was never sold to Russia. It was sold to Iraq instead. 48. Why did the Russians invite Mr. Bayer to hunt bears?A. Russian bears are famous for their cruelty.B. They managed to find a bear for hunting.C. They expected the trade to be successful.D. There was a bear in Moscow Circus. 49. Why did the Russians say “Be careful, the Russian bears are very dangerous, and frightening”?A. To tell Mr. Bayer that many people had been killed by bears.B. To make Mr. Bayer feel the hunting really challenging.C. To warn Mr. Bayer to mind his safety while hunting.D. To tell Mr. Bayer that the bear is really dangerous. 50. We can infer from the last paragraph that _.A. Mr
