单选题Electronic Mail During the past few years, scientists all over the world have suddenly found themselves productively engaged in task they once spent their lives avoiding—writing, any kind of writing, but particularly letter writing. Encouraged by electronic mail"s surprisingly high speed, convenience and economy, people who never before touched the stuff are regularly, skillfully, even cheerfully tapping out a great deal of correspondence. Electronic networks, woven into the fabric of scientific communication these days, are the route to colleagues in distant countries, shared data, bulletin boards and electronic journals. Anyone with a personal computer, a modern and the software to link computers over telephone lines can sign on. An estimated five million scientists have done so with more joining every day, most of them communicating through a bundle of interconnected domestic and foreign routes known collectively as the Internet, or net. E-mail is starting to edge out the fax, the telephone, overnight mail, and of course, land mail. It shrinks time and distance between scientific collaborators, in part because it is conveniently asynchronous (异步的)(Writer can type while their colleagues across time zones sleep; their message will be waiting). If it is not yet speeding discoveries, it is certainly accelerating communication. Jeremy Bernstein, the physicist and science writer, once called E-mail the physicist"s umbilical cord (脐带). Later other people, too, have been discovering its connective virtues. Physicists are using it; college students are using it; everybody is using it; and as a sign that it has come of age, the New Yorker has celebrated its liberating presence with a cartoon—an appreciative dog seated at a keyboard, saying happily, "On the Internet, nobody knows you"re a dog."

单选题下面有3篇短文，每篇短文后有5道题，每道题后面有4个选项。{{B}}第一篇{{/B}} {{B}}Modern Sun Worshippers{{/B}} People travel for a lot of reasons. Some tourists go to see battlefields or religious shrines. Others are looking for culture, or simply want to have their pictures taken in front of famous places. But most European tourists are looking for a sunny beach to lie on. Northern Europeans are willing to pay a lot of money and put up with a lot of inconveniences for the sun because they have so little of it. Residents of cities like London, Copenhagen, and Amsterdam spend a lot of their winter in the dark because the days are so short, and much of the rest of the year in the rain. This is the reason the Mediterranean has always attracted them. Every summer, more than 25 million people travel to Mediterranean resorts and beaches for their vacation. They all come for the same reason: sun! The huge crowds mean lots of money for the economies of Mediterranean countries. Italy's 30,000 hotels are booked solid every summer. And 13 million people camp out on French beaches, parks, and roadsides. Spain's long sandy coastline attracts more people than anywhere else. 37 million tourists visit yearly, or one tourist for every person living in Spain. But there are signs that the area is getting more tourism than it can handle. The Mediterranean is already one of the most polluted seas on earth. And with increased tourism, it's getting worse. The French can't figure out what to do with all the garbage left by campers around St. Tropez. And in many places, swimming is dangerous because of pollution. None of this, however, is spoiling anyone's fun. The Mediterranean gets more popular every year with tourists. Obviously, they don't go there for clean water and solitude. They tolerate traffic jams and seem to like crowded beaches. They don't even mind the pollution. No matter how dirty the water is, the coastline still looks beautiful. And as long as the sun shines, it's still better than sitting in the cold rain in Berlin, London, or Oslo.

单选题下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} The Beginning of American Literature American has always been a land of beginnings. After Europeans 'discovered' America in the fifteenth century, the mysterious New World became for many people a genuine hope of a new life, an escape from poverty and persecution, a chance to start again. We can say that, as nation, America begins with that hope. When, however, does American literature begin? American literature begins with American experiences. Long before the first colonists arrived, before Christopher Columbus, before the Northmen who 'found' America about the year 1,000, Native Americans lived here. Each tribe's literature was tightly woven into the fabric of daily life and reflected the unmistakably American experience of lining with the land. Another kind of experience, one filled with fear and excitement, found its expression in the reports that Columbus and other explorers sent home in Spain, France and England. In addition, the journals of the people who lived and died in the New England wilderness tell unforgettable tales of hard and sometimes heartbreaking experiences of those early years. Experience, then, is the key to early American literature. The New World provided a great variety of experiences, and these experiences demanded a wide variety of expressions by an even wider variety of early American writers. These writers included John Smith, who spent only two-and-a-half years on the American continent. They included Jonathan Edwards and William Byrd, who thought of themselves as British subjects, never suspecting a revolution that would create a United States of America with a literature of its own. American Indians, explorers, Puritan ministers, frontier wives, plantation owner -- they are all the creators of the first American literature.
