The problem with history is simple. There is too much of it, And more of it comes along every day. We need something that will cut the past down to size. We want heroes and heroines that a modern person can identify with. That is where Hollywood comes in.

Film makers have often based their work on historical events. Why go to the trouble of writing a brand new story when so many exciting things have happened in the pasty People will often already know the story, That leaves the director free to thrill us with details of what life as like in imperial China or ancient Rome. Most historians dislike this attitude. They see history as a complex thing, influenced by great political and economic forces. Film audiences are not very interested in this. They want kings and queens. They pay their money to see fancy clothes and a good fight. And this is what the film industry tries to give them. Sometimes this approach can cause trouble. The film Titanic was a success around the world. In one of the film's most dramatic moments, a member of the ship's crew begins shooting into the crowd trying to get into the lifeboats as the ship sinks. When the film was released, the real life sailor's surviving relatives protested. They pointed out that this was not what had actually happened The film makers made a public apology. But everyone who has seen the film remembers the sight of the man shooting into the crowd. Defenders of "Hollywood history" say that most of the time the film makers get the facts right. The action is based on real events and the clothes are accurate. People talk in the way that they would have done in the past even if they do it with a modern American accent. For many people, a historical film will be the closest they come to discovering the past. It is still possible to find mistakes. Millions have been spent on putting together a replica of ancient Rome. The costumes are right and the atmosphere is perfect. Yet if you look very closely, a plane can be seen passing through the sky above. Some film makers say that history needs to be simplified if it is to be filmed. The film maker's job is to make viewers interested. If they want to know more, they can do their own research. The difference between film history and real history is the difference between the facts and the truth. We can watch a "costume drama" and know that all the materials used are probably accurate. But if we want to find out the whole story, we have to do it ourselves. We have to go back to the books. The main point of the passage is______. A．that films based on past events are often big hits B．how much we can trust the Hollywood version of history C．that we should read books rather than see films to know the history D．why film audiences are interested in film history rather than real history

In the college-admissions wars, we parents are the true fighters. We're pushing our kids to get good grades, take SAT preparatory courses and build resumes so they can get into the college of our first choice. We say our motives are selfless and sensible. A degree from Stanford or Princeton is the ticket for life. If Aaron and Nicole don't get in, they're forever doomed. Gosh, we're delusional.

I've twice been to the wars, and as I survey the battlefield, something different is happening. It's the one-upmanship among parents. We see our kids' college rating as medals proving how well or how poorly we've raised them. But we can't acknowledge that our obsession is more about us than them. So we've contrived various justifications that turn out to be half-truths, prejudices or myths. It actually doesn't matter much whether Aaron and Nicole go to Stanford. Admissions anxiety afflicts only a minority of parents. It's true that getting into college has generally become tougher because the number of high-school graduates has grown. From 1994 to 2006, the increase is 28 percent. Still, 64 percent of freshmen attend schools where acceptance rates exceed 70 percent, and the application surge at elite schools dwarfs population growth. Take Yale. In 1994, it accepted 18.9 percent of 12,991 applicants; this year it admitted only 8.6 percent of 21,000. We have a full-blown prestige panic; we worry that there won't be enough medals to go around. Fearful parents prod their children to apply to more schools than ever. "The epicenters (of parental anxiety) used to be on the coasts, Boston, New York, Washington, Los Angeles", says Tom Parker, Amherst's admissions dean. "But it's radiated throughout the country". Underlying the hysteria is the belief that scarce elite degrees must be highly valuable. Their graduates must enjoy more success because they get a better education and develop better contacts. All that's plausible and mostly wrong. "We haven't found any convincing evidence that selectivity or prestige matters", says Ernest T. Pascarella of the University of Iowa, co author of "How College Affects Students", an 827-page evaluation of hundreds of studies of the college experience. Selective schools don't systematically employ better instructional approaches than less-selective schools, according to a study by Pascarella and George Kuh of Indiana University. Some do; some don't. On two measures professors' feedback and the number of essay exams selective schools do slightly worse. In the author's eyes, parents pushing their kids to an elite degree are ______. A．aggressive B．misguided C．reasonable D．failing

The controversial Anglo-French supersonic transport plane, the Concorde, had attracted much attention because it is unusually loud. A late-model jumbo 747, for example, creates 100 or more decibels of sound over an eight-square-kilometer area. The Concorde spreads a 100-decibel-plus blanket of noise over some 140 square kilometers. On takeoff, the Concorde sounds like four F-4 fighter jets taking off at once. Its penetrating, low-frequency rumble makes the Concorde "completely distinctive" from other jets.

What bothers noise experts is that plenty of commonplace machines are just as loud as, or even louder than, the Concorde. A sanitation truck can be noisier, and so can a heavy diesel truck pulling away from a stop sign. One expert who has gone out of his way to dramatize the prevalent offensiveness of the city sound-scale is Dr. Thomas H. Fay, director of speech and hearing at Columbia-Presbyterian Medical Center in New York. Dr. Fay took a sound-meter into a New York City subway and proved that an approaching train can be twice as loud as the Concorde. Since World War Ⅱ, the number of the high-powered noise-makers, from trucks and motorcycles to air conditioners and sirens has increased almost geometrically. It' s no wonder that in many areas of the country, especially in the suburbs, the average sound level has doubled in 20 years. Noise experts estimate that city noises are increasing a half-decibel a year. They found that in 1971 the quietest parts of Los Angeles--thought to be a relatively quiet city--were louder than the loudest districts of New York in 1937. This passage mainly talks about ______ . A．the problem of the supersonic transport plane, the Concorde B．a comparison between the Concorde and other machines C．the problem of noise D．noise in the suburbs
