       On a November morning in New York, Alan Pakula climbed into his Volvo and began the l00-mile drive from Manhattan to his Long Island house. The well-known movie director (Sophie's Choice, All the President’s Men) had made the mp countless tunes without incident.

       As the 70-year-old Pakula neared Exit 49 on the Long Island Expressway just before noon, a vehicle ahead of him drove over a seven-foot steel bar on the road, kicking it into the air. Within seconds, the bar shot through Pakula's car, smashing into his-forehead and killing him almost instantly. Authorities never determined where the bar came from.

       News reports called it a "freak" accident, which puts it in the same kind as other tragedies to make headlines in recent years, a 22-year-old New Jersey woman was left with broken bones after mining sharply to avoid a deer; a 24-year-old Washington woman needed major reconstructive surgery after a wall unit fell off a truck and smashed into her face; a young couple were killed by a falling tree that crushed their SUV on a suburban New York parkway.

       Though the details of each are unique, these accidents share a common, unsettling theme: the way bidden dangers on, in, and around our roads claim innocent lives.

       It is estimated that there are at least 1.6 million car accidents a year involving trees, animals and vehicle debris (碎片). A Reader's Digest analysis of government data found that in 2007, such crashes caused over 800 deaths. Even scarier: These accidents are increasing. From 2002 to 2007, deaths tied to vehicle debris jumped 43 percent, from 298 a year to 427．Animal-car deaths rose 38 percent, from 152 to 210.

       That's just part of the story. With unexpected crashes just a part of the 6.3 million accidents, 2.9 million injuries and 42, 600 road deaths, they get limited notice compared to drunk driving. That means the root causes go ignored on the documents of the government.

　The way people hold to the belief that a fun - filled, pain free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.

　　As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment （预担的义务）, self - improvement.

　　Ask a bachelor（单身汉） why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.

　　Couples with infant children are lucky to get a whole night’s sleep or a three - day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.

　　Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.

According to the author, a bachelor resists marriage chiefly because ________ .

　　A. he is reluctant to take on family responsiblilities

　　B. he believes that life will be more cheerful if he remains single

　　C. he finds more fun in dating than in marriage

　　D. he fears it will put an end to all his fun adventure and excitement

　Raising children, in the author’s opinion is ________ .

　　A. a moral duty

　　B. a thankless job

　　C. a rewarding task

　　D. a source of inevitable pain

From the last paragraph, we learn that envy sometimes stems from ________ .

　　A. hatred　　　　　　　　　　　　B. misunderstanding

　　C. prejudice　　　　　　　　　　　D. ignorance

To understand what true happiness is one must ________ .

　　A. have as much fun as possible during one’s lifetime

　　B. make every effort to liberate oneself from pain

　　C. put up with pain under all circumstances

　　D. be able to distinguish happiness from fun

High school is different  50  everyone, but there’s one thing that’s  51  .You’re going to have just as much fun here as you  52  before. But having fun isn’t enough though!
