单选题The State of Marriage Today Is there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded. almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times, and extramarital(婚外的) affairs will be even more common than they are now. But what are the reasons for this, and is the picture really so gloomy(阴暗的)? The answer to the first question is really quite simple. marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands as they usually didn't have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don't feel that they need to stay in a failing marriage. In answer to the second question, the outlook may not be as pessimistic(悲观的) as it seems. While the rate of divorce has risen, the rate o~ couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now simply live together and don't bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive. So is marriage really an outdated institution? The fact that most people still get married indicates that it isn't. And it 'is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!

单选题Defending the Theory of Evolution Still Seems Needed Judith S. Weis, a biology professor who serves as president of the American Institute of Biological Sciences(AIBS) is leading a nationwide effort to" defend" the theory of evolution. Weis leads the effort in the face of what the institute views as opposition and indifference from school boards and government entities. The Institute believes that the teaching of evolution in America is being diminished by the teaching of creationism as well as by an overall lack of teaching Darwin's theory in high school. "There's nothing that requires schools to teach evolution. Sometimes teachers in high schools just leave it out. However from the point of view of biologists, evolution is the central theory of biology upon which everything is based," said Weis. "Unfortunately, teaching evolution has become a political issue in many parts of the country and AIBS, as a representative of biologists, wanted to be a major force speaking out in favor of its teaching. " Weis said the institute is working together with the American Geological Institute and the National Association of Biology Teachers and its 80 - plus member organizations to address the political and legislative threats to teaching evolution. In states challenging its teaching, the institute responds by sending letters to school boards and state legislatures, by providing testimony at public meetings and by notifying members and affiliated organizations. AIBS, with more than 80 member societies and 250,000 members, has established an email system enabling scientists and teachers in each state, and member societies, to keep each other informed about threats to the teaching of evolution. Darwin's theory of evolution holds that living things change and adapt to their environment and that present - day species (including human beings) are descended from earlier species through modification by natural selection. The theory has been accepted by scientists for nearly 100 years, Weis said, and has been refined, extended and strengthened over the years by findings, in developmental biology. Discoveries in genetics, molecular biology and genomics - all of which provide significant benefits for human health - would not be possible without the underlying knowledge of evolution. And, Weis adds," modern molecular biology and genomics have increased our understanding of how evolution works. "Nonetheless, evolution remains a politically, if not scientifically, controversial issue. Weis said that this year alone, seven states have had either local or statewide efforts to water down the teaching of evolution, or" balance" it with the teaching of creationism - a religious belief that different species were created separately by a higher power, such as God. "Rarely does anyone now use the word 'creationsm' , because that's too obvious. "Weis said, "The current terminology is 'intelligent design. '/

单选题My First Job I was six when I joined my father and two elder brothers at sunrise in the fields of Eufaula, Oklahoma. 1 the time I was eight I was helping Dad fix up old furniture.

My main responsibilities (职责) were 3 tables and washing dishes, but sometimes I helped cook. Every day after school I would 4 to JM"s and work until ten. Even on Saturdays, I worked from two until eleven. At that age it was difficult going to work and 5 my friends run off to swim or play.

单选题Hitchhiking When I was in my teens and 20s, hitchhiking was a main form of long-distance transport. The kindness or curiosity of strangers 1 me all over Europe, North America, Asia and Southern Africa. Some of the lift-givers became friends, many provided hospitality 2 the road. Not only did you find out much more about a country than 3 traveling by train or plane, but also there was that element of excitement about where you would finish up that night. Hitchhiking featured importantly in Western culture. It has books and songs about it. So what has happened to 4 ? A few years ago, I asked the same question about hitchhiking in a column on a newspaper. 5 of people from all over the world responded with their view on the state of hitchhiking. "If there is a hitchhiker"s 6 , it must be Iran," came one reply. Rural Ireland was recommended as a friendly place for hitchhiking, 7 was Quebec, Canada-"if you don"t mind being berated for not speaking French. " But while hitchhiking was clearly still alive and well in many parts of the world, the 8 feeling was that throughout much of the west it was doomed. With so much news about crime in the media, people assumed that anyone on the open road without the money for even a bus ticket must present a danger. But do we 9 to be so wary both to hitchhike and to give a lift? In Poland in the 1960s, 10 a Polish woman who e-mailed me, "The authorities introduted the Hitchhiker"s Booklet. The booklet contained coupons for drivers, so each time a driver who had 11 somebody, he or she received a coupon. At the end of the season, 12 who had picked up the most hikers were rewarded with various prizes. Everybody was hitchhiking then. " Surely this is a good idea for society. Hitchhiking would increase respect by breaking down 13 between strangers. It would help fight 14 warming by cutting down on fuel consumption as hitchhikers would be using existing fuels. It would also improve educational standards by delivering instant 15 in geography, history, politics and sociology.

单选题Telling Tales about People One of the most common types of nonfiction, and one that many people enjoy reading, is stories about people's lives. These stories fall into three general categories: autobiography, memoir, and biography. An autobiography is the story of a person's life written by himself or herself. Often it begins with the person's earliest recollections and ends in the present. Autobiography writers may not be entirely objective in the way they present themselves. However, they offer the reader a good look at the way they are and what makes them that way. People as diverse as Benjamin Franklin and Helen Keller have written autobiographies of other writers, such as James Joyce, have written thinly fictionalized accounts of their lives. These are not autobiographies, but they are very close to it. Memoirs, strictly speaking, are autobiographical accounts that focus as much on the events of the times as on the life of the author~ 2Memoir writers typically use these events as backdrops for their lives. They describe them in detail and discuss their importance. Recently, though, the term memoir seems to be becoming interchangeable with autobiography. A memoir nowadays may or may not deal with the outside world. Biographies are factual accounts of someone else's life. In many senses, these may be the hardest of the three types to write. Autobiography writers know the events they write about because they lived them. But biography writers have to gather information from as many different sources as possible. Then they have to decide which facts to include. Their goal is to present a balanced picture of a person, not one that is overly positive or too critical. A fair, well-presented biography may take years to research and write.

单选题The Race into Space American millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives," Tito explained. He loved his time in space, "Being in space and looking back at earth is one of the most rewarding experiences a human being can have." This kind of experience isn"t cheap. It cost $20 million. However, Tito achieved his dream, so he was happy. "For me it was a life dream. It was a dream that began when I didn"t have any money." he told reporters. On 30 April 2002, Mark Shuttleworth became the world"s second space tourist. Shuttleworth is a South African businessman. At the age of twenty-eight, he also paid $20 million for the eight day trip. Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesn"t exist yet. Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it"s so expensive, only very rich people can go into space. They want space travel to be available to more people. That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty- five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga for $2 million. However, space flight is still very dangerous. Bill Readdy is NASA"s deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this it may take time before space tourism really takes off. You might be able to go up, but will you come down?
