Doctors have known for a long time that extremely loud noises can cause hearing damage or loss.The no
ise 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 mire 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.

字词句段篇系列答案It was a beautiful day at the beach—blue sky, gentle wind, calm sea．I knew these things because a man sitting five feet from me was shouting them into his mobile phone, like a play-by-play announcer （实况解说员）.
“IT’S A BEAUTIFUL DAY,” he shouted．“THE SKY IS BLUE, AND THERE’S A GENTLE WIND, AND THE WATER IS CALM, AND…”
Behind me, a woman, her mobile phone pressed to her ear was walking back and forth.
“She DIDN’T,” she was saying．“No．She DIDN’T．She DID? Really? Are you SERIOUS? She did NOT．She DID? No she…”
And so on．This woman had two children, who were playing in the sea．I found myself watching them, because the woman surely was not．A huge squid could have caught and snatched the children, and this woman would not have noticed．Or, if she had noticed, she’d have said, “Listen．I have to go, because a huge squid just……No! She didn’t ! She DID? No! She……”
And next to me, the play-by-play man would have said: “…AND A HUGE SQUID JUST ATE TWO CHILDREN, AND I’M GETTING A LITTLE SUNBURNED, AND …”
It used to be that the major trouble at the beach was the fellow who brought a boom box （便携式录音机） and turned it up so loud that the bass notes caused seagulls to explode．But at least you knew where these fellows were; you never know which beachgoers have mobile phones．You’ll settle next to what appears to be a sleeping sunbather, or even （you hope） a corpse , and you’ll lie happily on your towel, and you’ll get all the way to the second sentence of your 467-page book before you fall asleep to the hypnotic surge of the surf （催人入梦的潮声）, and …
BREEP! BREEP! The corpse sits up, feels urgently for its mobile phone, and shouts “Hello! I’m at the beach! Yes! It’s nice! Very peaceful! What? She did? No, she didn’t! She DID? No, she…”
Loud mobile-phoners never seem to get urgent calls．Just once, I’d like to hear one of them say, “Hello? Yes, this is Dr．Johnson．Oh, Dr．Smith．You’ve opened the abdominal cavity （腹腔）? Good! Now the appendix should be right under the … What? No, that’s the liver．Don’t take THAT out, ha ha! Oh, you did? My God! OK, now listen carefully…”

Do you want to live a happier, less stressful (有压力的) life?
Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world – and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first Laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. “Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing – it’s the universal language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects (效果) of laughter on our health. According to a 5 – year study in the body. Laughter improves our health against illness by about 40%.
So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest – I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha,” while looking at each other. However, our bodies can’t tell the difference between fake laughter and real laughter, so they still produce the same healthy effects.
Surprisingly, it works! After ten minutes everybody in the room was laughing for real – and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results!
【小题1】In which country was the first Laughter Club started?
| A．Britain. | B．America. | C．Australia. | D．India. |
| A．Surprised. | B．Pleased. | C．Nervous. | D．Stressful. |
| A．After a few minutes. | B．After a few hours. |
| C．After a few seconds. | D．After a few days. |

| B．40% of the people in Laughter Clubs are good friends. |
| C．Adults laugh more often than children in a day. |
| D．Laughing is the best way to prevent illness. |
