Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected.
An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.
The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.Doctors have long known that__________.
| A．one may lose his hearing when he hears a terribly loud noise. |

The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago; but it has brought new problems. One of the biggest is pollution. To pollute mean to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in a place, men moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world, but it is not only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight pollution. They stop the people from burning coal in houses and factories in the city, and from blowing dirty smoke into the air.
The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must keep careful of the rise in pollution at the same time. Our world is becoming much smaller ___________.
| A．because the earth is being polluted day and night. |
| B．thanks to science developing. |
| C．because of the rise in pollution |
| D．because the earth is blown away by the wind every year. |

In today’s Internet age, online games can be a change from the pressure of school and work. However, they can also cause problems and unhealthy addictions. This is most clearly seen in the example of South Korea. This country has the world’s highest percentage of high – speed Internet services. It has also a high number of game players who are addicted to online games.
In 2004, a young man died after playing online games almost nonstop for 86 hours. A 12 – year – old boy stole $ 16,000 from his father to continue online games which he could not get away from. Such problems are spreading to other parts of Asia as well. In 2005, it was reported that about 80 percent of China’s 13.8 million online game players were under 25. And many of these were said to be addicted. Such numbers point toward a growing problem among Chinese youth.
Dr. Sue – Huei Chen, a psychologist , discovered some signs of at – risk people. Such people often go online to escape from their problems. And they usually have no friendship or good social skills. They feel the need to spend more and more time online, so they may be absent from school or family. And they become upset if anyone tries to limit their online game playing.The passage is mainly about .

Losing a baby tooth can be fun for a kid. You can put it under your pillow and look forward to finding some money there in the morning. And then you can watch your new permanent(永恒的) tooth grow in its place.
But if a permanent tooth falls out, that’s a problem. There isn’t another one under the gum(齿龈)that can replace it. Unfortunately, this happens to some older people. And if permanent teeth fall out-or need to be pulled-an older person might need dentures.
Dentures, known as false teeth, are a set of replacement teeth for any teeth that are missing. There are partial dentures, which take the place of only a few teeth and prevent the others from changing position. If all the teeth are gone, the person would need complete dentures, which replace every tooth in the mouth.
Dentures can cause pains at first and take some time to get adjusted to. They also need special care. They should be brushed daily with a special denture brush and cleanser and soaked in denture solution when not in the mouth.
Dentures are important for older folks because, without teeth, it’s hard to smile, talk, and eat properly. But it can be a little weird if you see someone take out his or her dentures. It can also be strange to see someone, like a grandparent, without dentures in because he or she won’t have any teeth. Try not to make fun of the person because this could cause hurt feelings.
People usually lose their permanent teeth due to periodontal disease, or gum disease, which is caused by bacteria that attacks the gums. Diseased gums aren’t strong and healthy, so teeth can get loose and fall out. Older people often have many cavities(洞)that have been filled over the years, and these fillings can weaken over time, leading to more tooth decay(腐烂).If one of your baby teeth falls out, he or she .
| A．should have a false tooth fixed in its place |
| B．have to put it under your pillow at once |
| C．will gain a permanent tooth in future |
| D．can exchange it for some money |
A person wearing dentures .
| A．should brush them with a special denture brush every few days |
| B．will take a very long time to adjust himself or herself to them |
| C．will experience unpleasant feelings at the beginning of fixing them |
| D．should use denture solution to soak them in his or her mouth |
Which of the following is NOT true according to the passage?
| A．Partial dentures can prevent the remaining teeth from changing position. |
| B．Old people will find it hard to smile, talk, and eat properly without teeth. |
| C．A person’s teeth will possibly get loose if diseases strike his gums. |
| D．It is hard for a person to wear dentures if all his teeth have fallen out. |
What does the underlined word “weird” mean in the fifth paragraph?
| A．inconvenient | B．strange | C．uncomfortable | D．impolite |
American society is not nap (午睡)friendly . In fact , says David Dings , sleep specialist at the University of Pennsylvania School of Medicine , “There’s even a prohibition (禁止) against admitting we need sleep”. Nobody wants to be caught napping or found asleep at work . To quote a proverb : “Some sleep five hours , nature requires seven , laziness nine and wickedness(淘气的) eleven.”
The way not to fall asleep at work is to take naps when you need them . “We have to totally change our attitude toward napping ,” says Dr. William Dement of Stanford University , the godfather of sleep research .
Last year a national commission led by Dement identified(发现) an “American sleep debt” which one member said was as important as the national debt . The commission was concerned about the dangers of sleepiness : people causing industrial accidents or falling asleep while driving . This may be why we have a new sleep policy in the White House . According to recent reports , President Clinton is trying to take a half---hour snooze (瞌睡) every afternoon .
About 60 percent of American adults nap when given the opportunity . We seem to have “a mid afternoon quiet phase ,” also called “a secondary sleep gate .” Sleeping 15 minutes to two hours in the early afternoon can reduce stress and make us refreshed . Clearly , we were born to nap .
We superstars of snooze don’t nap to replace lost shut--eye or to prepare for a night shift . Rather , we “snack” on sleep ,whenever , wherever and at whatever time we feel like it . I myself have napped in buses , cars , planes and on boats ; on floors and beds ;and in libraries , offices and museums . The research done by the Dement Commission shows that Americans .
| A．don’t like to take naps |
| B．are terribly worried about their national debt |
| C．think that lack of enough sleep causes many accidents |
| D．have caused many industrial and traffic accidents |
