考题 Questions 61-65 are based on Passage Two:Passage TwoScience is a dominant theme in our culture．Since it touches almost every facet of our life, educated people need at least some acquaintance with its structure and operatiom They should also 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 acquaintance with science is superficial; for the person who has been presented with science as a musty storehouse 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, or-independent 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 scientific 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 of the scientific 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．To offset this built-in bias, we have adopted the policy of using plural nouns and pronouns whenever possible and, when a'bsolutely necessary, alternating he and she．This policy is far 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 is usually informal． We feel, as do many other scientists, that we shouldn't take ourselves too seriously． As the reader may observe, we see science as a delightful pastime rather than as a grim and dreary way to earn a living．According to the passage, “scientific subculture”means ( )．A．cultural groups that are formed by scientistsB．people whose knowledge of science is very limitedC． the scientific communityD． people who make good contributions to science

考题共用题干 Mad Scientist Stereotype OutdatedDo people still imagine a physicist as a bearded man in glasses or has the image of the mad scientist changed?The Institute of Physics set out to find out whether the stereotype of a physics"boffin"（科学家）still exists by conducting a survey on shoppers in London. The people were asked to identify the physicist from a photograph of a line-up of possible suspects.98 percent of those asked got it wrong.The majority of people picked a white male of around 60,wearing glasses and with a white beard.While this stereotype may have been the image of an average physicist fifty years ago, the reality is now very different. Since 1 960 the number of young women entering physics has doubled and the average age of a physicist is now 31.The stereotype of the absent-minded scientist has lasted a long time because the media and Hollywood help promote the image of men in white lab coats with glasses sitting by blackboards full of equations（等式）or working with fizzing（嘶嘶响）test tubes. These stereotypes are really damaging to society.Very good school children are put off studying science because they don't see people like themselves on television or in magazines doing science.They simply don't relate to the media's image of the mad scientist.This is one reason why fewer young people are choosing to do science at university.Ifwe want to encourage more young people to study science subjects,we need to change this image of the scientist and make science careers more attractive.But we must also develop children's interest in science.In an attempt to change this negative image,an increasing number of science festivals are being organized.Thousands of people from secondary schools are also encouraged to take part in nationwide science competitions of which the most popular are the national science Olympiads.Winning national teams then get the opportunity to take part in the International Science Olympiads which are held in a different country every year.These events are all interesting for the young people who take part but they only involve a small proportion of students who are already interested in science.It seems that there is a long way to go before science becomes attractive as subjects like computer studies or fashion and design.The majority of physicists in Britain today are Cambridge graduates.A:Right B:Wrong C:Not mentioned

考题问答题Practice 9　　Youth unemployment across the world has climbed to a new high and is likely to climb further this year, a United Nations agency said Thursday, while warning of a “lost generation” as more young people give up the search for work.　　The agency, the International Labor Organization, said in a report that of some 620 million young people ages 15 to 24 in the work force, about 81 million were unemployed at the end of 2009—the highest level in two decades of record-keeping by the organization, which is based in Geneva.　　“There’s never been an increase of this magnitude — both in terms of the rate and the level — since we’ve been tracking the data,” said Steven Kapsos, an economist with the organization. The agency forecast that the global youth unemployment rate would continue to increase through 2010, to 13.1 percent, as the effects of the economic downturn continue. It should then decline to 12.7 percent in 2011.　　In some especially strained European countries, including Spain and Britain, many young people have become discouraged and given up the job hunt, it said. The trend will have “significant consequences for young people,” as more and more join the ranks of the already unemployed, it said. That has the potential to create a “‘lost generation’ comprised of young people who have dropped out of the labor market, having lost all hope of being able to work for a decent living.”　　The report studied the German, British, Spanish and Estonian labor markets and found that Germany had been most successful in bringing down long-term youth unemployment. In Spain and Britain, increases in unemployment were particularly pronounced for those with lower education levels.　　Data from Eurostat, the European Union’s statistical agency, show Spain had a jobless rate of 40.5 percent in May for people under 25. That was the highest level among the 27 members of the European Union, far greater than the 9.4 percent in Germany in May and 19.7 percent in Britain in March.
