Here's to Your Health
As the only freshman on his school's varsity(代表队) wrestling team, Tod was anxious to fit in with his older teammates. One night after a match, he was offered a whisky bottle on the ride home. Tod felt he had to accept, or he would seem like a sissy. He took a swallow, and every time the bottle was passed back to him, he took another swallow. After seven swallows, he passed out. His terrified teammates carried him into his home, and his mother then rushed to the hospital. After his stomach was pumped, Tod learned that his blood alcohol level had been so high that he was lucky not to be in a coma or dead.
Although alcohol sometimes causes rapid poisoning, frequently leads to long-term addiction, and always threatens self-control, our society encourages drinking. Many parents, by their example, give children the impression that alcohol is an essential ingredient of social gatherings. Peer pressure turns bachelor parties, fraternity initiations (同仁联谊会入会) , and spring-semester beach vacations into competitions in "getting trashed. " In soap operas, charming characters pour Scotch whiskey from crystal bottle as readily as most people turn on the faucet for tap water. In films and rock videos, trend-setters party in nightclubs and bars. And who can recall a televised baseball or basketball game without a beer commercial? By the age of 21, the average American has been drinking on TV about 75, 000 times. Alcohol ads appear with pounding frequency—in magazines, on billboards, in college newspapers—contributing to a harmful myth about drinking.
Part of the myth is that liquor signals professional success. In a men's magazine, one full-page ad for Scotch whiskey shows two men seated in an elegant restaurant. Both are in their thirties, perfectly groomed, and wearing expensive grey suits. The windows'are draped (悬挂) with velvet (天鹅绒) > the table with spotless white linen. Each place-setting consists of a long-stemmed water goblet, silver utensils and thick silver plates. On each plate is half-empty cocktail glass. The two men are grinning and shaking hands, as if they've just concluded a business deal. The caption reads, "The taste of success. "
Contrary to what the liquor company would have us believe, drinking is more closely related to lack of success than to achievement. Among students, the heaviest drinkers have the lowest grades. In the work force, alcoholics are frequently late or absent, tend to perform poorly, and often get fired. Although, alcohol abuse occurs in all economic classes, it remains most severe among the poor.
Another part of the alcohol myth is that drinking makes you more attractive to the opposite sex. "Hot, hot, hot," one commercial's soundtrack(电影配乐) begins, as the camera scans a crowd of college-age beachgoers. Next it follows the curve of a woman's leg up to her bare hip and lingers there. She is young, beautiful, wearing a bikini. A young guy, carrying an ice chest (箱子), positions himself near to where she sits. He is tan, muscular. She doesn't show much interest—until he opens the chest and takes out a beer. Now she smiles over at him. He raises his eyebrows and, invitingly, holds up another can. She joins him. This beer, the song concludes, "attracts like no other. "
Beer doesn't make anyone sexier. Like all alcohol, it lowers the levels of male hormones in men and of female hormones in women—even when taken in small amounts. In substantial amounts, alcohol can cause infertility(不生育) in women and impotence in men. Some alcoholic men develop enlarged breasts, from their increased female hormones.
The alcohol myth also creates the illusion that beer and athletics are a perfect combination. One billboard features three high-action images: a baseball player running at top speed, a surfer riding a wave, and a basketball player leaping to make a dunk shot. A particular light beer, the billboard promises, "won't slow you down. "
"Slow you down" is exactly what alcohol does. Drinking plays a role in over six million injuries each year—not counting automobile accidents. Even in small amounts, alcohol dulls the brain, reducing muscle coordination and slowing reaction time. It also interferes with the ability to focus the eyes and adjust to a sudden change in brightness—such as the flash of a car's headlights. Drinking and driving, responsible for over half of all automobile deaths, is the leading cause of death among teenagers. Continued alcohol abuse can physically alter the brain, permanently damaging learning and memory. Long-term drinking is related to malnutrition, weakening of the bones, and ulcers. It increases the risk of liver failure, heart disease, and stomach cancer.
Finally, according to the myth fostered by the media in our culture, alcohol generates a warm glow of happiness that unifies the family. In one popular film, the only food visible at a wedding reception is an untouched wedding cake, but beer, whiskey, and vodka flow freely. Most of the guests are drunk. After shouting into the microphone to get everyone's attention, the band leader asks the bride and groom to come forward. They are presented with two wine-filled silver drinking cups. "If you can drink your cups without spilling any wine," the band leader tells them, "you will have good luck for the rest of your lives. " The couple drain their cups without taking a breath, and the crowd cheers.
A marriage, however, is unlikely to be "lucky" if alcohol plays a major role in it. Nearly two-thirds of domestic violence involves drinking. Alcohol abuse by parents is strongly tied to child neglect and juvenile delinquency. Drinking during pregnancy can lead to miscarriage and is a major cause of such birth defects as deformed limbs and mental retardation. Those who depend on alcohol are far from happy: over a fourth of the patients in state and county mental institutions have alcohol problems; more than half of all violent crimes are alcohol-related; the rate of suicide among alcoholics is fifteen times higher than among the general population.
Alcohol, some would have us believe, is part of being successful, sexy, healthy, and happy. But those who have suffered from it—directly or indirectly—know otherwise. For alcohol's victims, "Here's to your health" rings with a terrible irony when it is accompanied by the clink of liquor glasses.
1. The author provides lots of evidence to refute the harmful myth about drinking.
2. We can conclude from the passage that the media and the culture of American society promote false beliefs about alcohol.
3. Paragraph four tells us that alcoholics will never succeed if they don't quit drinking.
4. Instead of making people more attractive, alcohol makes man womanlike.
5. Drinking is one of the main causes of death among teenagers.
6. The sentence " our society encourages drinking. " is simply based on the fact that there are so many ads for alcohol in magazines and on TV.
7. Something cet6w.com restrain alcohol abuse before it is too late.
8. Over six million injuries each year are related to______.
9. The life of those who are addicted to drinking is______.
10. Besides a major cause of birth defects, drinking during pregnancy can lead to______.
I. Y 2. Y 3. N 4. N 5. Y 6. N 7. NG 8. drinking 9. far from happy 10. miscarriage

A liquid can be kept in an open container and fill it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the__1__available; it must therefore be kept in a closed container or held by a gravitational field, as in the__2__of a planet's atmosphere. The distinction was a __3__feature of early theories describing the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be "dissolved" in a vapor without losing its identity, and another theory__4 __that the two phases are made up of different kinds of molecules. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in __5 __They are both forms of matter that have no __6 __structure, and they both flow readily.
The fundamental similarity of liquids and gases becomes clearly apparent when the temperature and pressure are __7__somewhat. Suppose a closed container __8__filled with a liquid is heated.

英语六级考试阅读题专项练习及答案 篇3
In the early days of nuclear power, the United States make money on it. But today opponents (反对者 ) have so complicated its development that no nuclear plants have been ordered or built here in 12 years.
The greatest fear of nuclear power opponents has always been a reactor "meltdown". Today, the chances of a meltdown that would threaten U. S. public health are very little. But to even further reduce the possibility, engineers are testing new reactors that rely not on human judgment to shut them down but on the laws of nature. Now General Electric is already building two advanced reactors in Japan. But don't expect them even on U. S. shores unless things change in Washington.
The procedure for licensing nuclear power plants is a bad dream. Any time during, or even after, construction, an objection by any group or individual can bring everything to a halt while the matter is investigated or taken to court. Meanwhile, the builder must add nice-but-not-necessary improvements, some of which force him to knock down walls and start over. In every case when a plant has been opposed, the Nuclear Regulation Commission has ultimately granted a license to construct or operate. But the victory often costs so much that the utility ends up abandoning the plant anyway.
A case in point is the Shoreham plant on New York's Long Island. Shoreham was a virtual twin to the Millstone plant in Connecticut, both ordered in the mid-60's. Millstone, completed for $ 101 million, has been generating electricity for two decades. Shoreham, however, was singled out by antinuclear activists who, by sending in endless protests, drove the cost over $ 5 billion and delayed its use for many years.
Shoreham finally won its operation license. But the plant has never produced a watt power. Governor Mario Cuomo, an opponent of a Shoreham start up, used his power to force New York's public-utilities commission to accept the following settlement: the power company could pass the cost of Shoreham along to its consumers only if it agreed not to operate the plant. I'oday, a perfectly good facility, capable of servicing hundreds of thousands of homes, sits rusting.
21.The author's attitude toward the development of nuclear power is______.
A. negative B. neutral
C. positive D. questioning
22.What has made the procedure for licensing nuclear power plants a bad dream?
A. The inefficiency of the Nuclear Regulation Commission. B. The enormous cost of construction and operation.
C. The length of time it takes to make investigations.
D. The objection of the opponents of nuclear power.
23.It can be inferred from Paragraph 2 that______.
A. there are not enough safety measures in the U. S. for running new nuclear power plants
B. it is not technical difficulties that prevent the building of nuclear power plants in the U. S.
C. there are already more nuclear power plants than necessary in the U. S.
D. the American government will not allow Japanese nuclear reactors to be installed in the U. S.
24. Governor Mario Cuomo's chief intention in proposing the settlement was to_______.
A. stop the Shoreham plant from going into operation
B. urge the power company to further increase its power supply
C. permit the Shoreham plant to operate under certain conditions
D. help the power company to solve its financial problems
25. The phrase "single out" is closest in meaning to_______.
A. delay B. end up
C. complete D. separate
答案
21. C 22. D 23. B 24. A 25. D
英语六级考试阅读题专项练习及答案 篇4
It is doing something better than other people that makes us unique. Yet a surprising number of people still see individuality as a surface thing. They wear bright clothes, dye their hair strange colors and decorate their skin with tattoos (文身) to make some kind of social statement.
The whole purpose of individuality is excellence. The people who comprehend the simple principle of being unique through performance make our entire political and economic system work. Those who invent, who improve, who know more about a subject than other people do, and who take something that doesn't work and make it work—these people are the very soul of capitalism.
Charles Kettering didn't like the idea of cranking a car to make it start, so he invented the electric starter. Henry Ford figured out the assembly-line technique and made it possible to mass-produce automobiles. Lewis Waterman saw no need to go on dipping a pen into an inkwell, so he put the ink into the pen. George Westinghouse told the world how to stop a train, and Elisha Otis, inventor of the elevator, indirectly created the city skyline. These people understood that individualism means working at the top of one's capacity.
Fortunately, enough Americans have been inspired to do something with their uniqueness that we have developed in less than three centuries from a frontier outpost into not only a country of freedom but a country strong enough to protect that freedom. These people prized the notions of individuality and excellence above all things and thus kept the great machine functioning. The ones with the purple hair and the horrorable jewelry are just along for the ride, trying to be "different" and not knowing how to go about it.
1 The student who earns A's on his report card has grasped the idea and has found the real meaning of individuality. So has the youngster who has designed his own spaceship, who paints pictures of the world around him, or who can name all the states and their capitals. According to the author unique individuals are persons who______.
A. do something better than other people
B. know more about a subject than other people
C. excel others in work
D. all of the above
2、People who regard individuality as a surface thing always do the following EXCEPT
A. wearing bright clothes B. coloring their hair
C. doing better than others D. decorating their skin with tattoos
3、Which is NOT TRUE according to the passage?
A. Henry Ford invented assembly-line technique.
B. Elisha Otis was the inventor of the lift
C. George Westinghouse created cranks.
D. Lewis Waterman put the ink into the pen.
4、It can be inferred from the passage that______.
A. the real secret to being unique lies in our excellent work
B. if we want to be different we'd gain more profit
C the student who earns A's on the report card has not grasped the real meaning of individuality
D. all Americans work miracles In the writer's opinion
5、who has understood the sense of individuality?
A. The youngster who designed his own spaceship.
B. The youngster who painted worthy pictures.
C. The youngster who was interested in wearing strange clothes.
D. Both A and B.
答案
D C C A D
英语六级考试阅读题专项练习及答案 篇5
The General Electric Company, often criticized for the complexity of its structure and the resulting opacity of its numbers, said yesterday that it would break GE Capital, by far its largest business, into four businesses. The reorganization effectively eliminates the job of Denis J. Nayden, 48, the chairman of GE Capital. Each of the new units will have its own chief, who Will report directly to Jeffrey R. Immelt, G. E.'s chairman. "The reason for doing this is simple. I want more direct contact with the financial services teams," Mr. Immelt said.
The new businesses are GE Commercial Finance, GE Insurance, SE Consumer Finance and GE Equipment Management. Some support functions within GE Capital, including risk management and treasury, will now report to Dennis Dammerman, 57, a G. E. vice chairman who preceded Mr. Nayden as GE Capital's chlef. Mr, Nayden will remain at G. E. as an adviser for now, but is expected to leave shortly to start a financial services firm.
Mr. Dammerman insisted that the reorganization had nothing to do with the increasing clamor from investors, regulators and the news media for greater transparency in accounting and for chief executives to take more responsibility for businesses: Analysts seem to believe him. "This is just what it appears to be, a managerial, reorganization which gives leaders more direct access to the office of the chairman," said Martin A. Sankey, a G. E. analyst.
The executives leading the new units will also sit on G.. E. 's corporate executive council, a committee made up of the company's top 25 executives, which meets periodically and discusses various strategic and management issues.
GE Capital, the company's largest nit, provided $55 billion of G. E. 's $124 billion in revenue last year and $ 5.6 billion of its $19.7 billion in pretax profits. The rest of G. E. had been divided into 11 other businesses, many of them--lighting and appliances are examples-much smaller than the new GE Capital units, yet each run by someone who reports directly to the chairman. Mr. Dammermn said that Mr. Immelt began talking about breaking GE Capital into more manageable pieces as soon as he took over as chief executive last September. "Jeff didn't like the extra layer between him and the GE Capital businesses,"
G. E. has tried to make GE Capital less mysterious to 'the outside world. Although GE Capital was officially one unit, it had begun to report quarterly results in live product-related segments--a number that will be reduced to four with the new organization. And analysts say GE Capital's management has been more accessible than it was in past years, and that Mr. Immelt and other G. E. corporate executives have been willing to discuss GE Capital in more depth.
57. After the reorganization, GE will have altogether ______.
A) six businesses B) sixteen businesses
C) four businesses . D) fifteen businesses
58. Which of the following statements is NOT true of Dennis Dammerman?
A) He is now a GE's vice chairman.
B) He is expected to leave GE to start a new financial services firm.
C) He was once the chairman of GE Capital.
D) He regards the reorganization of GE as an initiative of its own.
59. All the following statements are False of Denis Nayden EXCEPT that ______.
A) the reorganization makes him lose his position as a chairman
B) he will remain for some time at GE as an analyst
C) he is currently GE's chairman
D) he is expected to start a new GE financial firm in the near future
60. The reorganization will enable GE's chief executive to ______.
A) quiet down the unrest in the world
B) work in a more friendly business environment
C) have more direct contact with GE's financial services teams
D) appear less mysterious to the outside world
61. The General Electric Capital ______.
A) is divided into five product-related segments now
B) provided more than 1/3 of GE's revenue last year
C) is going to be broken into more businesses
D) now has smaller units than all other businesses in GE
答案
57.文章第五段提到“the rest of G.E，had been divided into 11 other businesses”，也就是除 GE Capital之外共有11家公司。文章第一段指出GE Capital将被分成4家公司。因此，调整结构以后，GE共有15家公司。答案为D项。
58.第二段第二句指出Dennis Dammerman是GE的副总裁，曾在Nayden之前做过GE Capital的主席。因此，选项A和C都排除。第三段中，Dammerman否认GE的结构调整和外界的压力有关，因此选项D说结构调整是GE自己的主动性举措符合原文意思，可排除。而第二段的最后一句中明确陈述即将离开GE的是Nayden，故答案为B项。
59.根据文章第一段中的“The reorganization effectively eliminates the job of Denis J. Nayden，48，the chairman of GE Capital.”可知正确答案为A项。
60.第三段的`最后一句“This is just what it appears to be，a managerial reorganization which gives leaders more direct access to the office of the chairman”即“And analysts say GE Capital's management has been more accessible than it was in past years”，因此，答案为C项。
61.此题是关于GE Capital的细节信息题。文章第五段第一句“GE Capital，the company's largest nit，provided $55 billion of G.E.'s $124 billion in revenue last year and $5.6 billion of its $19.7 billion in pretax profits.”提到去年GE Capital收入550亿美金占GE总收入1240亿的三分之一多。因此，正确答案为B项。
英语六级考试阅读题专项练习及答案 篇6
It is all very well to blame traffic jams,the cost of petrol and the quick pace of modern life,but mannerson the roads are becoming horrible.Everybody knows that the nicest men become monsters behind the wheel.Itis all very well,again,to have a tiger in the tank,but to have one in the driver's seat is another matter altogether.You might tolerate the odd road-hog，the rude and inconsiderate driver,but nowadays the well-mannered motorist is the exception to the rule.Perhaps the situation calls for a "Be Kind to Other Drivers"campaign,otherwise it may get completely out of hand.
Road politeness is not only good manners, but good sense too.It takes the most cool-headed and good-tempered of drivers to resist the temptation to revenge when subjected to uncivilized behavior.On the other hand,a little politeness goes a long way towards relieving the tensions of motoring.A friendly nod or a wave of acknowledgement in response to an act of politeness when they see it.
However,misplaced politeness can also be dangerous.Typical examples are the driver who brakes violently toallow a car to emerge from a side street at some hazard to following traffic,when a few seconds later the road would be clear anyway;or the man who waves a child across a zebra crossing into the path of oncoming vehicles that may be unable to stop in time.The same goes for encouraging old ladies to cross the road wherever and whenever they care to.It always amazes me that the highways are not covered with the dead bodiesof these grannies.
A veteran driver,whose manners are faultless,told me it would help if motorists learnt to filter correctlyinto traffic streams one at a time without causing the total blockages that give rise to bad temper.Unfortunately,modern motorists can't even learn to drive,let alone master the subtler aspects of roadsmanship.Years age the experts warned us that the car-ownership explosion would demand a lot more give-and-take from all road users.It is high fime for all of us to take this message to heart.
1.According to the passage,people's behaviors on the roads are becoming_____________________.
2.What does the author suggest in order to get control of the situation?
3.Drivers who can manage to control their impulse to revenge when they experience impolite behavior are considered as_________________by the author.
4.Encouraging old ladies to cross the road at the wrong moment is referred as______________by the author.
5.Experts have long pointed out that all road users should be ready to yield to each other due to______________________.
答案：
1.[horrible]
[定位]根据题干中的behaviors on the roads定位到首段首句。
解析：题干中的people's behaviors是原文中manners的同义替换。空白处需要形容词作表语，故填人horrible即可。
2.[A"Be Kind to Other Drivers"campaign.]
[定位]根据题干中的get control和situation定位到首段末句。
解析：原文中的get out of hand意为“失控”，与题干中的get control of“控制”刚好相反。原文说需要发起某一活动来控制这种情形，否则后果严重，可见为了控制局面，就要发起这一活动，该活动即答案。
3.[the most cool-headed and good-tempered.]
[定位]根据题干中的drivers，to revenge等定位到第2段第2句。
解析：题干中的control their impulse to相当于原文的resist the temptation to,experience impolite behavior也是原文subjected to uncivilized behavior的同义替换。原文提到某些司机在遇到不文明行为时能忍住报复的冲动，空白处需填描述这些司机的形容词或名词(词组)，即the most cool-headed and good-tempered。
4.[misplaced politeness]
[定位]根据题干中的encouraging old ladies to cross the road定位到第3段。
解析：该段首句是主题句，讲述了misplaced politeness是很危险的行为，并举例证明。原文该段倒数第二句中的The same goes for指的就是这种行为。主题句中的主语即本题答案。
5.[the car-ownership explosion]
[定位]根据题干中的'Experts和pointed out查找到末段倒数第2句。
解析：原文中的Years ago the experts warned对应题干中的Experts have long pointed out,而be ready to yield toeach other是原文中demand a lot more give-and-take的同义替换，故原文该句that从句中的主语the car-ownership explosion部分即为答案。
