21世纪大学英语读写教程第3册第9单元课文解读2

　　It is expected that the discovery of possible life-forms from the planet Mars will revive public interest in space exploration. But is public support for the international space effort necessary, given that politicians seem determined to press ahead with it anyway?

　　The race to the moon, which was won by the Americans in 1969, was driven almost entirely by politics. The rivalry between the U.S. and the former Soviet Union meant that the two countries were determined to be the first to put a man on the moon. President John F. Kennedy promised that America would win this race and, as one of the most popular presidents in American history, he inspired a nation to think of space exploration as the ultimate test of America"s superiority over her Soviet enemy.

　　America"s success as the first nation to reach the moon, coupled with continuing Cold War rivalry, created much public support for the space programme and Washington was able to fund many more missions. During the 1970s, the moon was visited again, unmanned missions were sent to Mars and, for the first time, man-made craft were put on paths that would take them out of the solar system.

　　But, by the 1980s, public support for space exploration was declining. It faded almost entirely after the Challenger space shuttle disaster of 1986, and the U.S. government was under pressure to scale back its space programme. Politicians reacted by demanding cuts in spending, which put the future of many space missions in doubt.

　　In Russia, funding was also a problem. The end of the Soviet Union meant the country could no longer afford to sustain its space programme. In fact, spending became so tight that there was often not enough money to bring home astronauts working on the country"s Mir space station.

　　But, in the last few years, politicians seem to have changed their attitude to space exploration, even though there is little evidence that the public have. New missions to Mars are planned, and plenty of money is being spent on other extraterrestrial activities. Last year, for instance, the U.S. spent more on space research and development than on any other area of research, except health and the military.

　　And spending is likely to increase in the coming years: currently, the National Aeronautics and Space Administration (NASA) is planning a number of missions to Mars, and it is pressing ahead with the most expensive space-exploration project ever undertaken — the International Space Station. (Three years ago, this project — a collaboration between the U.S., Canada, Russia, Europe and Japan — came within one vote of being canceled by the American House of Representatives.)

　　And the Americans are not the only ones spending huge sums on space exploration. The Europeans, Canadians and Japanese are expected to spend $9 billion on their share of the space station, and Europe has already spent huge sums developing its Ariane rockets, the most recent of which — Ariane 5 — blew up shortly after it was launched. The Russians, too, claim they are committed to supporting the International Space Station — an expense that country seems ill able to afford.

　　So, if there is little public support for space exploration, where does the impetus to fund these activities come from? Promoting the cause of science is one possible answer. But recently there has been considerable controversy over whether projects like the International Space Station have enough scientific value to merit the billions that have been and will be spent on it.

　　NASA"s reasons for building the space station are "to develop new materials [and] technologies that will have immediate, practical applications". However, for such research to be worthwhile, NASA needs private companies to develop (and help pay for) extraterrestrial research. Unfortunately, the cost of sending anything into orbit is so high that most private companies favour improving techniques on Earth. Significantly, NASA has so far not managed to get any substantial private investment to manufacture products in space.

　　The result is that the station seems, at present, to have only one concrete objective: research into how people can live and work safely and efficiently in space. But how important is this research? And can it possibly justify the cost of this huge orbiting laboratory?

　　The only purpose of studying how humans live and work in space would be to prepare for long-term space missions. At present, none are planned, and this seems unlikely to change in the near future. The main reasons for this are the costs. A manned mission to our nearest planetary neighbour Mars, for example, would cost around $400 billion. This is $50 billion more than Russia"s present Gross Domestic Product (GDP).

　　And even if one accepts that this research is important, can it justify building a space station the size of 14 tennis courts, at a cost which is eventually expected to exceed $100 billion? Given the shortage of funds in many other areas of scientific research, it would seem not.

　　So why build it? There are good political reasons for doing so. It will provide work for the thousands of unemployed defence workers who depended on the Cold War for their jobs, and who make up a substantial proportion of voters in both Russia and the U.S. It will also help keep American/Russian ties strong — another reason NASA believes the space station is a good investment. (Critics argue that there are far cheaper ways to keep the U.S. and Russia on good terms.)

　　And then there is the legacy of the Cold War. The Berlin Wall may have fallen, but NASA and the U.S. government still seem to believe in the ideal of one nation"s superiority in space. Indeed, NASA describes the space station as "a powerful symbol of U.S. leadership".

　　It seems that the world"s politicians are caught in a timewarp. They still believe, as they did in the 1960s, that man must conquer space in order to prove he is master of his surroundings. If only it weren"t so expensive.

21世纪大学英语读写教程第4册第8单元课文讲解1

　　Bill Heavy

　　When my father rings, I hurry down to the front door of my condo. There he is, in corduroy pants, the tread worn off the knees, and a shirt I outgrew in tenth grade. He"s come to help me put in a new garbage disposal. Actually, I"m helping him. His mechanical gene passed over his only son, on its way to some future generation. At 39, I"ve made my peace with this.

　　My father hasn"t been to my place since he helped me paint four years ago. The truth is, I"m often not sure how to talk to him. But this time it will be easy. We have a job to do.

　　In minutes he has taken over the whole enterprise, lying under the sink and squinting up into the machinery. And suddenly I am 12 years old again, watching him fix things and feeling useless.

　　As a child, I identified so strongly with my mother that I thought my father was just a long-term house guest with spanking privileges. She and I are bookish, introverted worriers. My father is an optimist who has never had a sleepless night in his life.

　　Like most fathers and sons, we fought. But there was no cooling-off period between rounds. It was a cold war lasting from the onset of my adolescence until I went off to college in 1973.I hated him. He was a former navy fighter pilot, with an Irish temper and a belief that all the problems of the world—including an overprotected son who never saw anything through to completion—could be cured by the application of more discipline.

　　At a time when an eighth-grader"s social status was measured in the fraction of an inch of hair kissing his collar, my father would march me down to the barbershop on Saturdays and triumphantly tell the man with the scissors. "Just leave him enough to comb." I would close my eyes, determined not to give him the satisfaction of seeing me cry. Without even thinking about it, I froze him out of my life, speaking only when spoken to. I learned to use silence like a knife. My one communique for an entire dinner was usually a sarcastic "May I be excused now? I have homework."

　　I lay awake at night imagining him being transferred by the gas company he worked for to an oil rig in the North Sea. But it didn"t happen, and soon all that remained was the contest of wills.

　　I went off to college, but he was still in my head. I could hear his voice every time I fell short in anything. Only when I began seeing my freelance articles in print did I begin to feel that I was slipping beyond his reach and into my own life.

　　Eventually I discovered that there is no anti-inflammatory agent like time. Now I wondered, could this aging 74-year-old be the giant who once thundered up the stairs to spank me, of whom I was so afraid that I wet my pants? In his place was someone I worried about, whom I dressed in my down hunting jacket for his annual pilgrimage to the Army-Navy game. My profession, which he had once ridiculed, saying, "Gee, do you think there"s any money in it?" now became a source of pride when fellow Rotarians mistook him for Bill Heavy "the writer." It was as if now that I no longer needed so desperately to please him, I had succeeded. We had become two old veterans from opposing armies, shaking hands years after the fighting, the combat so distant as to be a dream.

　　Before we can install the disposal, we have to snake out the pipes. Soon we get stuck trying to figure out how a gasket fits.

　　"Ah," he says finally, "we"re going to have to call a plumber."

　　This is not how I remember him. He used to be so stubborn, the kind of guy who could make IRS examiners throw up their hands in frustration and let him off. Now that I have his mind-set and don"t want to give up, it"s as if he"s acquired mine.

　　He says, "Besides, I gotta get home. Your mother and I have to be at a dinner party at 7:30."

　　"Don"t you pay for the plumber," he says. "Putting this thing in is part of my Christmas present to you."

　　Though we"ve failed to install the disposal, it"s been oddly satisfying. At last we"re on even ground. Maybe he wasn"t the best father. Maybe I wasn"t the best son, but I realize I will never be ready to cope with his leaving. I know that I"m luckier than some of my friends, whose fathers died while they were still locked in the battle that neither really wanted.

　　The plumber comes two days later. He secures the disposal in its place as easily as I buckle my belt.

　　Not long ago, I started badgering my parents to get their estate in order. They didn"t want to deal with it. I finally wrote them a letter saying if I were a parent, I would want to make * sure the IRS got as little of my money as possible. I knew this would push my father"s buttons. It worked. They met with a lawyer.xc

　　Later, my father and I lunch at a restaurant near my office so he can fill me in on the details. "One thing I don"t want you to worry about is what"ll happen to me," he says, with the satisfied air of a man who has taken care of business. "The Navy will cremate me for free."

　　"And what about the ashes?" I ask, concerned only with practical things. It is as if we are talking about how to get rid of the old disposal.

　　"They scatter them at sea." He turns away, looking around for our waiter. Something breaks inside me. When he turns back, I am crying, hot tears springing up in my eyes so suddenly I"m almost choking.

　　"I don"t want you to die," I manage to say. "I don"t want them to scatter your ashes. I"ll scatter your ashes."

　　"Oh, Bill," he says, taken aback, totally at a loss about what to say. "I just didn"t want to burden you with it."

　　I have no way to tell him that I want to be burdened with it, that it is my birth right to be burdened with it. "I know," I say.

　　I don"t even look around to see if anybody is watching. I don"t care. I reach across the table for his hand and hold it, trying to stop the tears.

21世纪大学英语读写教程第三册第1单元课文讲解1

　　A common misconception among youngsters attending school is that their teachers were child prodigies. Who else but a bookworm, with none of the normal kid"s tendency to play rather than study, would grow up to be a teacher anyway?

　　I"ve tried desperately to explain to my students that the image they have of me as an enthusiastic devotee of books and homework during my adolescence was a bit out of focus. On the contrary, I hated compulsory education with a passion. I could never quite accept the notion of having to go to school while the fish were biting.

　　But in my sophomore year, something beautiful and exciting happened. Cupid aimed his arrow and struck me right in the heart. All at once, I enjoyed going to school, if only to gaze at the lovely face in English II.

　　My princess sat near the pencil sharpener, and that year I ground up enough pencils to fuel a campfire. Alas, Debbie was far beyond my wildest dreams. We were separated not only by five rows of desks, but by about 50 I.Q. points. She was the top student in English II, the apple of Mrs. Larrivee"s eye.

　　Occasionally, Debbie would catch me staring at her, and she would flash a smile that radiated intelligence and quickened my heartbeat. It was a smile that signaled hope and made me temporarily forget the intellectual gulf that separated us.

　　I schemed desperately to bridge that gulf. And one day, as I was passing the supermarket, an idea came to me. A sign in the window announced that the store was offering the first volume of a set of encyclopedias at the special price of 29 cents. The remaining volumes would cost $2.49 each.

　　I purchased Volume I — Aardvark to Asteroid — and began my venture into the world of knowledge. I would henceforth become a seeker of facts. I would become Chief Brain in English II and sweep my princess off her feet with a surge of erudition. I had it all planned.

　　My first opportunity came one day in the cafeteria line. I looked behind me and there she was.

　　"Hi," she said.

　　After a pause, I wet my lips and said, "Know where anchovies come from?"

　　She seemed surprised. "No, I don"t."

　　I breathed a sigh of relief. "The anchovy lives in salt water and is rarely found in fresh water." I had to talk fast, so that I could get all the facts in before we reached the cash register. "Fishermen catch anchovies in the Mediterranean Sea and along the Atlantic coast near Spain and Portugal."

　　"How fascinating," said Debbie, shaking her head in disbelief. It was obvious that I had made quite an impression.

　　A few days later, during a fire drill, I casually went up to her and asked, "Ever been to the Aleutian Islands?"

　　"Never have," she replied.

　　"Might be a nice place to visit, but I certainly wouldn"t want to live there," I said.

　　"Why not?" said Debbie, playing right into my hands.

　　"Well, the climate is forbidding. There are no trees on any of the 100 or more islands in the group. The ground is rocky and very little plant life can grow on it."

　　"I don"t think I"d even care to visit," she said.

　　The fire drill was over and we began to file into the building, so I had to step it up to get the natives in. "The Aleuts are short and sturdy and have dark skin and black hair. They live on fish, and they trap blue foxes and seals for their valuable fur."

　　Debbie"s eyes widened in amazement.

　　One day I was browsing through the library. I spotted Debbie sitting at a table, absorbed in a crossword puzzle. She was frowning, apparently stumped on a word. I leaned over and asked if I could help.

　　"Four-letter word for Oriental female servant," Debbie said.

　　"Try amah," I said, quick as a flash.

　　Debbie filled in the blanks, then turned to stare at me in amazement. "I don"t believe it," she said. "I just don"t believe it."

　　And so it went, that glorious, joyous, romantic sophomore year. Debbie seemed to relish our little conversations and hung on my every word. Naturally, the more I read, the more my confidence grew.

　　In the classroom, too, I was gradually making my presence felt. One day, during a discussion of Coleridge"s "The Ancient Mariner", we came across the word albatross.

　　"Can anyone tell us what an albatross is?" asked Mrs. Larrivee.

　　My hand shot up. "The albatross is a large bird that lives mostly in the ocean regions below the equator, but may be found in the north Pacific as well. The albatross measures as long as four feet and has the greatest wingspread of any bird. It feeds on fish and shellfish. The albatross has an enormous appetite, and when it"s full it has trouble getting into the air again."

　　There was a long silence in the room. Mrs. Larrivee couldn"t quite believe what she had just heard. I sneaked a look at Debbie and gave her a big wink. She beamed proudly and winked back.

　　What I failed to perceive was that Debbie all this while was going steady with a junior from a neighboring school — a basketball player with a C+ average. The revelation hit me hard, and for a while I felt like forgetting everything I had learned. I had saved enough money to buy Volume II — Asthma to Bullfinch — but was strongly tempted to invest in a basketball instead.

　　I felt not only hurt, but betrayed. Like Agamemnon, but with less drastic consequences, thank God.

　　In time I recovered from my wounds. The next year Debbie moved from the neighborhood and transferred to another school. Soon she became no more than a memory.

　　Although the original incentive was gone, I continued poring over the encyclopedias, as well as an increasing number of other books. Having tasted of the wine of knowledge, I could not now alter my course. For:

　　"A little knowledge is a dangerous thing:

　　Drink deep, or taste not the Pierian spring."

　　So wrote Alexander Pope, Volume XIV — Paprika to Pterodactyl.

——21世纪大学英语读写基础教程The Future课文解读60篇

21世纪大学英语读写基础教程The Future课文解读1

　　What will our future be like? What might happen in the year 2144? How far can your imagination take you into the future? Let"s see what a newspaper in New Zealand tells us.

　　The Future

　　Will the future be one of robots and spaceships, or meditation and organic food? Today and next Wednesday The Post steps into the future, and asks the experts what they think the world of tomorrow will be like.

　　Imagine you are holding the December 11, 2144 edition of The Evening Post. It won"t be made of paper, but a thin screen that can be folded up and put in your pocket or bag. You"ll use the same screen tomorrow, when the day"s news will be beamed to its tiny modem via satellite.

　　The modem will chatter away all day, updating stories from around the world as they happen, complete with moving pictures and sound. A retina scanner will follow your eye, scrolling each page as you get near the bottom. The paper"s com*r will record which stories interest you most and design a custom menu every time you switch it on.

　　Let"s see what"s happening today. Again, the big local story is the disappearing apartment blocks at Happy Valley. Built over an old landfill, this expensive new development is slowly sinking into the ground. Engineers suspect plastic milk bottles dumped with their caps screwed on in the late-20th century are bursting under the weight of the buildings. "People back then," says Wellington"s Mayor in a live interview, "were pretty stupid."

　　Overseas a power failure at a cryo-prison in Alabama during the holiday weekend saw 50,000 inmates thawed prematurely, and in Bangladesh monsoon floods have wiped out hundreds of villages. Some things don"t change.

　　In reality, we can"t predict what the pages of this newspaper will contain 144 years from now because we can"t predict the future. But in two weeks we will arrive in the new millennium, a date long held up as the future, but which will soon represent a new beginning.

　　Thirty years ago it was expected that by 2000 commuters would fly to work on highways in the sky, that robots with pinnies would do the vacuuming, that humans would have colonised our near planets and the moon.

　　Our cars are still stuck firmly on the ground, although even the most basic family runabout has a powerful electronic brain which tells it how much fuel to use and figures out in milliseconds how to save the occupants in a crash.

　　We still do the vacuuming ourselves, although our ovens tell us when food is ready. We can download whole libraries through our home com*rs and view snaps of friends on the other side of the world seconds after they are taken.

　　We have yet to live anywhere other than Earth, although missions into space have allowed us to develop new medicines, information chips and superconductors to make life better down here.

　　Who would have believed we"d be altering the genetic make-up of animals so they can grow replacement organs for us? Who"d have believed the drink machine in the foyer dials for supplies when it senses it"s getting low?

　　At the dawn of the new millennium the future seems to be coming at us at a frightening pace, with the world seeming to change almost weekly.

　　What then, will it be like in 100 years? 500? 1000? Will it be a technological future with space hotels, rocket cars, genetically engineered people and automated homes? Or will it be an organic future with a new emphasis on spirituality and nature?

　　Will humankind still be blighted by war? Will we be able to cure cancer? Will we still get married? What sort of world will our children inherit?

　　Over the past few months The Post has been asking experts in their fields to take an educated, but fanciful, guess. None claims to be able to tell the future, but by tracking current trends they can give us an idea of what to expect in the world of tomorrow.

　　You won"t be around to read the December 11, 2144 edition of The Evening Post, but this is the next best thing.

　　Welcome to the future.
