单选题Science is a dominant theme in our culture．Since it touches almost every tacet of our life．educated people need at least some acquaintance with its structure and operation.They should aIso have an understanding of the subculture in which scientists live and the kinds of people they are．An understanding of general characteristics of science as well as sPecific scientific concepts is easier to attain if one knows something about the things that excite and frustrate the scientist． This book is written for the intelligent student or lay person whose acquantance with science is superficial；for the person who has been presented with science as a musty store-house of dried facts；for the person who sees the chief objective of science as the Production of gadgets；and for the person who views the scientist as some sort of magician.The book can be used to supplement a course in any science，to accompany any course that attempts to give an understanding of the modern world，orindependent of any course—simply to provide a better understanding of science．We hope this book will lead readers to a broader Perspective on scientific attitudes and a more realistic view of what science is，who scientists are，and what they do．It will give them an awareness and understanding of the relationshiP between science and our culture and an appreciation of the roles science may play in our culture．In addition，readers may learn tO appreciate the relationship between scienticfic views and some of the values and philosophies that are pervasive in our culture． We have tried to present in this book an accurate and up-to-date picture ot the scientlly community and the people who populate it．That population has in recent Years come to comprise more and more women．This increasing role of women in the scientific subculture is not an unique incident but，rather，part of the trend evident in all segments of societY as more women enter traditionally male—dominated fields and make significant contributions.In discussing these changes and contributions，however，we are faced with a language that is implicitly sexist，one that uses male nouns or pronouns in referring to unspecified individuals.Tioffset this built—in bias，we have adopted the policy of using plural nouns and Pronouns whenever possible and，when absolutely necessary，alternating he and she．This policy is{ar from being ideal，but it is at least an acknowledgment of the inadequacy of our language in treating half of the human race equally． We have also tried to make the book entertaining as well as informative.Our approach 18 usuallv informal．We feel，as do many other scientists，that we shouldn’t take ourselves too seriouslv．As the reader may observe，we see science as a delightful pastime rather than as a grim and dreary way to earn a living.

单选题It is estimated that in Tokyo 70% of single working women choose to live with their parents and only 50% of them pay some rent. After graduating from college, these women came back to their nest and never left. With their mothers taking care of them, these young ladies are not in a hurry to get married, since they don"t do housework or laundry, or cook. Happily unmarried, these called "parasite single", who have become the focus of the Japanese society, interpret marriage as lower standard of living and less money. "The problem is that Japan is very different from the United States or Europe, where after marriage it"s still possible for a woman to pursue a career, even after having a baby. While in Japan usually the husband doesn"t want the wife to work," says Mariko Kawana, who is 27 years old and works as a secretary. Her opinion is agreed by Miki Takasu, who carries a $2,900 Bubbery purse, and drives a BMW. "If a woman realizes there is something she wants to do after having been married, it is almost unlikely for her to come back to it." This is the first significant group of Japanese women to stay single beyond their early twenties. Their lifestyle and opinions define a kind of Tokyo yuppie. In the past 15 years, the number of women who are single into their late twenties has risen to 50%. They are crazy about shopping, and they spend most of their salaries on luxury and leisure. According to a nationwide survey, in 2003 they surprisingly covered 15% share in the total outbound leisure travel market from Japan, so they are targeted by travel agencies as "the office ladies". In 2002, a shopping tour which concentrated only on shopping in Milan attracted 700 Japanese single ladies in two months, featured none of Italy"s famous tourist attractions. The participants didn"t even try famous Italian food, but grabbed snacks on the run to the outlet shops. Girls like Miki, who are less affected by Japan"s economic downturn, can afford this lifestyle because they live with their parents and they have jobs, and most of their incomes are disposable. Opinions on these young women vary. Some people think that they are good for the economy because they spend their incomes on cars and clothes, while a large number of people think they are destroying society by refusing to get married and have children.

单选题 When we talk about intelligence, we do not mean the ability to get good scores in certain kinds of tests or even the ability to do well in school. By intelligence we mean a way of living and behaving, especially in a new or anxious situation. If we want to test intelligence, we need to find out how a person acts instead of how much he knows what to do. For example, when in a new situation, an intelligent person thinks about the situation, not about himself or what might happen to him. He tries to find out all he can, and then he acts immediately and tries to do something about it. He probably isn't sure how it will all work out, but at least he tries. And, if he can't make things work out right, he doesn't feel ashamed that he fails; he just tries to learn from his mistakes. An intelligent person, even if he is very young, has a special outlook (人生观) on life, special feeling about life, and knows how he fits into it. If you look at children, you'll see great difference between what we call "bright" children and "not bright" children. They are actually two different kinds of people, not just the same kind with different amounts of intelligence. For example, the bright child really wants to find out more about life——he tries to get in touch with everything around him. But the unintelligent child keeps more to himself and his own dream-world; he seems to have a wall between him and life in general.

单选题E At a certain time in our lives we consider every place as the possible site (地点) for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices. The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I had given for it. The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded (相邻) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn't been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said. I was not really troubled by the loss. I had always had a garden, but I don't think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted (不受约束的). It makes but little difference whether you own a farm or not.
