单选题B Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. At the beginning of the 20th century there was a big farm called Hollywood. From the 1910's to the 1950's, Hollywood was the film center of the world. Every family knew the names of its film stars — Charlie Chaplin, Greta Garbo, Bergman and hundreds more. The reason why people went to Hollywood to make films was the sun. At first, people made films in New York on the east coast of the United States. But then they heard about Los Angeles, where there are 350 days of the sun every year. As they made all the films by sunlight, the west coast was a much better place to work. Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film. When TV became popular, Hollywood started making films for television. Then in the 1970's they discovered people still went to the cinema to see big expensive films. Nowadays they are still making films in Hollywood and people see them all over the world.

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.
