单选题For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U.S. had acquired when it purchased Louisiana, and the Apollo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war. Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone before. Today Mars looms (隐约出现) as humanity"s next great terra incognita (未探明之地 ). And with doubtful prospects for a short-term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet"s reddish surface. Could it be that science, which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: Are there experiments that only humans could do on Mars? Could those experiments provide insights profound enough to justify the expense of sending people across interplanetary space? With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life. If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science; the prevalence of life in the universe.

单选题{{B}}Text 3{{/B}} Names have gained increasing importance in the competitive world of higher education. As colleges strive for market share, they are looking for names that project the image they want or reflect the changes they hope to make. Trenton State College, for example, became the College of New Jersey nine years ago when it began raising admissions standards and appealing to students from throughout the state. "All I hear in higher education is, 'Brand, brand, brand,'" said Tim Westerbeck, who specializes in branding and is managing director of Lipman Hearne, a marketing firm based in Chicago that works with universities and other nonprofit organizations. "There has been a sea change over the last 10 years. Marketing used to be almost a dirty word in higher education." Not all efforts at name changes are successful, of course. In 1997, the New School for Social Research became New School University to reflect its growth into a collection of eight colleges, offering a list of majors that includes psychology, music, urban studies and management. But New Yorkers continued to call it the New School. Now, after spending an undisclosed sum on an online survey and a marketing consultant's creation of "naming structures," "brand architecture" and "identity systems," the university has come up with a new name: the New School. Beginning Monday, it will adopt new logos(标识), banners, business cards and even new names for the individual colleges, all to include the words "the New School." Changes in names generally reveal significant shifts in how a college wants to be perceived. In altering its name from Cal State, Hayward, to Cal State, East Bay, the university hoped to project its expanding role in two mostly suburban counties east of San Francisco. The University of Southern Colorado, a state institution, became Colorado State University at Pueblo two years ago, hoping to highlight many internal changes, including offering more graduate programs and setting higher admissions standards. Beaver College turned itself into Arcadia University in 2001 for several reasons: to break the connection with its past as a women's college, to promote its growth into a full-fledged(完全成熟的) university and, officials acknowledged, to eliminate some jokes about the college's old name on late-night television and "morning zoo" radio shows. Many college officials said changing a name and image could produce substantial results. At Arcadia, in addition to the rise in applications, the average student's test score has increased by 60 points. Juli Roebeck, an Arcadia spokeswoman, said.

单选题Recorded music is the chief kind of radio entertainment. Most stations specialize in one kind of music, such as rock, classical, country' and western, or "old-time favorites". Some stations broadcast several kinds of music. Radio stations that broadcast music have disc jockeys who introduce and comment on the music. They play an important role. Each station tries to hire disc jockeys whose announcing styles and personalities appeal to the station's largest audience. Programs that provide information include newscasts, talk shows, and play-by-play(详细报道的) descriptions of sports events. Newscasts come on the air at regular times — every half-hour or hour on most stations. In addition, radio stations present on-the-spot news coverage of such special events as political conventions, space flights, Senate hearings, and speeches by the President. Radio stations also broadcast such specialized news as weather forecasts, traffic reports, and stock market and agricultural information. Other news features include public service announce ments about community events, activities of community groups, and government services. A few stations broadcast only news to serve listeners who prefer news programs to music. Talk shows present discussions on a variety of topics and interviews with people from many professions. Each show has a host or hostess who leads the discussion or does the interviewing. The subject of a program may be a current political topic, such as an election or a government policy, or it may deal with a social issue, such as crime, pollution, poverty, racism, or sexism. Many talk shows allow listeners to take part in the program. Listeners are invited to telephone the station to ask questions or give their opinions about the topic.

单选题 I doubt that any historically valid treatment of that presidential administration can emerge for at least another decade, if then. I confess that when I came out of the White House I signed up to do an "insider volume", but sober, professional second thoughts have led me to put that project on ice until at least 1980. The problem is that I simultaneously know too much, and not enough. I know what I thought was happening. But I cannot fully document what happened. And I have seen enough highly classified documents to know that most of what the observers thought was happening was at best half right, at worst dead wrong. This has steered me in a different direction as far as writing is concerned. I am now preparing what is frankly and unashamedly an ex parte memoir, "My Experiences in Washington." It is based on what I believed to be true, on the picture as I conceptualized it, of the presidential administration under which I worked.

单选题Science 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 operation. 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 scientists. This book is written for the intelligent student of 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 has been presented with science as the production of gadgets; and for the person who views the scientists as some sort of magicians. 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 independently 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 populated 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 a 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 contribution. In discussing these changes and contribution, 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 absolutely 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 haft of the human equally. We have also tried to make the book entertaining as well as informative. Our approach is usually informal. We feel, as many other scientists do, that we shouldn't take ourselves too seriously. As the reader may observe, we see science as a delightful pastime than as a grim and dreary way to earn a living.
