The smooth landing of shuttle(航天飞机)Discovery ended a flight that was successful in almost every respect but one: the dislodging of a big chunk of foam, like the one that doomed the Columbia. This flight was supposed to vault the shuttle fleet back into space after a prolonged grounding for repairs. But given the repeat of the very problem that two years of retooling was supposed to resolve ,the verdict is necessarily mixed. (1)Once again, the space agency has been forced to put off the flight until it can find a solution to the problem, and no one seems willing to guess how that may take.The Discovery astronauts performed superbly during their two-week mission, and the shuttle looked better than ever in some respects. (2)Space officials were justifiably happy that so much had gone well, despite daily worries over possible risks. the flight clearly achieved its prime objectives.The astronauts transferred tons of cargo to the international space station, which has been limping along overhead with a reduced crew and limited supplies carried up on smaller Russian spacecraft. (3)They replaced a broken device .repaired another and carted away a load of rubbish that had been left on the station,  showing the shuttle can bring full loads back down from space.This was the most scrutinized shuttle flight ever. with the vehicle undergoing close inspection while still in orbit. (4)New sensing and photographic equipment to look for potentially dangerous damage to the sensitive external skin proved valuable.  A new back flip maneuver allowed station astronauts to photograph the shuttle‘s underbelly, and an extra-long robotic arm enabled astronauts see parts of the shuttle that were previously out of sight.(5)The flood of images and the openness in discussing its uncertainties about potential hazards sometimes made it appear that the shuttle was about to fall apart,In the end the damage was clearly tolerable. A much-touted spacewalk to repair the shuttle's skin the first of its kind moved an astronaut close enough to pluck out some protruding material with his hand Preliminary evidence indicates that Discovery has far fewer nicks and gouges than shuttles on previous flights, perhaps showing that improvements to reduce the shedding of debris from the external fuel tank have had some success.

It looked just like another aircraft from the outside. The pilot told his young passengers that it was built in 1964.But appearances were deceptive and the 13 students from Europe and the USA who boarded the aircraft were in for the flight of their lives.Inside the area that normally had seats had become a long white tunnel. Heavily padded(填塞) from floor to ceiling it looked a bit strange. There were almost no windows , but lights along the padded walls illuminated it. Most of the seats had been taken out apart from a few at the back where the young scientists quickly took their places with a look of fear.For 12 months, science students from across the continents had competed to win a place on the flight at the invitation of the European Space Agency. The challenge had been to suggest imaginative experiments to be conducted in weightless conditions.For the next two hours the flight resembled that of an enormous bird which had lose its reason, shooting upwards towards the heavens before rushing towards Earth. The invention was to Achieve weightlessness for a few seconds.The aircraft took off smoothly enough. But any feelings that I and the young scientists had that we were on anything like a scheduled passenger service were quickly dismissed when the pilot put the plane into a 45 degree climb which lasted around 20 seconds. Then the engines cut our and we became weightless. Everything become confused and left or right. Up or down no longer had any meaning, after ten seconds of free fall descent the pilot pulled the aircraft out of its nosedive. The return of gravity was less immediate than its loss, but was still sudden enough to ensure that some students came down with a bump.Each time the pilot cut the engines and we became weightless. A new team conduct it experience. First it was the Ducth who wanted to discover how it is that cats always land on their feet. Then the German team who conducted a successful experiment on a traditional building method to see if could be used for building a further space station, the Americans had an idea to create solar sails that could be used by satellites.After two hours of going up and down in the lane doing their experiments, the predominate feeling was one of excitement rather than sickness. Most of the students thought it was an unforgettable experience and one they would be keen to repeat.1.What did the writer say about the plane?2.According to the writer ,how did the young scientists feel before the flight?3.What did the pilot do with the plane after it took off?4.According to the passage, the purpose of being weightless was to(  ).5.This passage was written to(  ).

Tens of thousands of 18 year olds will graduate this year and be handed meaningless diplomas .These diplomas won’t look any different from awarded their luckier classmates Their validity will be questioned only when their employers discover the these graduates are semiliterate(半文盲).Eventually a fortunate few will find their way into educational – repair – adult – literacy Programs, such as the one where I teach grammar and writing .There, high school graduates and high school dropouts pursuing graduate equivalency certificates will learn the skills they should have learned in school. They will discover they have been cheated by our educational system.I will never forget a teacher senior when be had her for English .“He site in the back of the room talking to his friends “.she told me,” Why don’t you move him to the front row?I urged believing the embarrassment would get him to settle down, Mrs. Stifter said , “I don’t move seniors. I think (使……不及格) them.” Our son’s academic life flashed before my eyes. No teacher had ever threatened him. By the time I got home I was feeling pretty good this. It was a radical approach for these times, but well. Why not? "She’s going to flunk you", I told my son.I did not discuss it any further. Suddenly English became a priority (头等重要) in his life. He finished out the semester with an A.I know one example doesn’t make a case, but at night I see a parade of students who are angry for having been passed along until they could no longer even pretend to keep up. Of average intelligence or better, they eventually quit school, concluding they were too dumb to finish. ”I should have been held back,” is a comment I hear frequently. Even sadder are those students who are high-school graduates who say to me after a few weeks of class. ”I don’t know how I ever got a high-school diploma.”Passing students who have not mastered the work cheats them and the employers who expect graduates to have basic skills. We excuse this dishonest behavior by saying kids can’t learn if they come from terrible environments. No one seems to stop to think that most kids don’t put school first on their list unless they perceive something is at risk. They’d rather be sailing.Many students I see at night have decided to make education a priority. They are motivated by the desire for a better job or the need to hang on to the one they’ve got. They have a healthy fear of failure.People of all ages can rise above their problems, but they need to have a reason to do so. Yong people generally don’t have the maturity to value education in the same way my adult students value it. But fear of failure can motivate both.1.What is the subject of this essay?2.How did Mrs. Sifter get the attention of one of the author’s children?3.The author believes that most effective way for a teacher is to (  ).  4.From the passage we can draw the conclusion that the authors’ attitude toward flunking is(  ).5.Judging from the content, this passage is probably written for(  ).

Office jobs are among the positions hardest hit by computation (计算机自动化). Word processors and typists will lose about 93,000 jobs over the next few years, while 57,000 secretarial jobs will vanish. Blame the PC: Today, many executives type their own memos and carry there” secretaries” in the palms of their hands. Time is also hard for stock clerks, whose ranks are expected to decrease by 68,000. And employees in manufacturing firms and wholesalers are being replaced with computerized systems.But not everyone who loses a job will end up in the unemployment line. Many will shift to growing positions within their own companies. When new technologies shook up the telecomm business, telephone operator Judy Dougherty pursued retraining. She is now a communications technician, earning about $ 64,000 per year. Of course, if you’ve been a tollbooth collector for the past 30 years, and you find yourself replaced by an E-ZPass machine, it may be of little consolation(安慰) to know that the telecom field is booming. And that’s just it: The service economy is fading: welcome to the expertise(专门知识) economy. To succeed in the new job market, you must be able to handle complex problems. Indeed, all but one of the 50 highest-paying occupations—air-traffic controller—demand at least a bachelor’s degree.For those with just a high school diploma(毕业证书).It’s going to get tougher to find a well-paying job. Since fewer factory and clerical jobs will be available .what’s left be the jobs that computations can’t kill, computers cant clean offices, or for Alzheimer’s patients(老年痴呆病人). But, since most people have the skills to fill those positions, the wages stay painfully low, meaning computation could drive an even deeper wedge (楔子) between the and poor, The best advice now, Never stop learning, and keep up with new technology.For busy adults of course that can be tough, the good news is that very technology that’s reducing so many jobs is a making it easier to go back to school without having to sit in a classroom. So called internet distance learning is hot, with more than three million students currently enrolled , and it’s gaining credibility with employers.Are you at risk of losing your job to a computer? Check the federal Bureau of Labor Statistics’ Occupational Outlook Handbook ,which is available online at bls.gov.1.From the first paragraph we can infer that all of the following persons are easily thrown into unemployment EXCEPT(  ).2.In the second paragraph the anther mentions the tollbooth collector to (  ).  3.By saying “...computation could drive an even deeper wedge between the rich and poor” (line 5. Para 4 )the author means (  ).  4.What is the author’s attitude towards computers?5.Which of the following might serve as the best title of passage?
