Scientists have known for a long time that very loud noises can cause hearing damage or loss (損失).
The noise can be the sound of an airplane or machines in factories or loud music or other common sounds
found at home or at work.
     A famous scientist has found that using aspirin (阿斯匹林) can increase the temporary (暫時(shí)的) hearing
loss or damage from loud noises. He did an experiment using a number of volunteers 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 volunteers who were given four grams of aspirin a day for two days suffered (受苦)
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 world use much larger amounts of aspirin than those used
in his experiment. He said these persons may face a serious danger of suffering hearing loss from loud noises.

     Hi, boys and girls! Do you know how to be a healthy kid? Here are some rules you should follow.
     First, eat different foods, especially fruit and vegetables. You may have a favorite food, but you should eat
something different. If you eat different foods, you will probably get more nutrients (營(yíng)養(yǎng)) your body needs.
     Second, drink water and milk as often as possible. When you're really thirsty, cold water is the best.
     Third, "listen" to your body. How do you feel when you are full? When you are eating, feel how your body
feels. When your stomach (胃) feels full, eating too much will not make you feel comfortable and will make
you fat.
     Fourth, limit (限制) screen time. Screen time is the time you watch TV, DVDs and videos, or using
computers. It is good to take more exercise such as playing basketball, swimming and so on. You can't watch
TV for more than two hours a day.

     Some people think that they have an answer to the problems of automobile crowding and pollution in large
cities. Their answer is the bicycle, or bike.
     In a great many cities, hundreds of people ride bicycles to work every day. In New York City, some bike
riders have even formed a group called "Bike for a Better City". They claim that if more people rode bicycles
to work there would be fewer automobiles in the downtown section of the city and therefore less dirty air
from car engines.
     For several years this group has been trying to get the city government to help bicycle riders. For example,
they want the city to paint special lanes-for bicycles only-on some of the main streets, because when bicycle
riders must use the same lanes as cars, there may be accidents. "Bike for Better City" feels that if there were
special lanes, more people would use bikes.
     But no bicycle lanes have been painted yet. Not everyone thinks it is a good idea. Taxi drivers don't like the
idea-they say it will slow traffic. Some store owners on the main streets don't like the idea-they say that if there
is less traffic, they will have less business. And most people live too far from downtown to travel by bike.
     The city government has not yet decided what to do. It wants to keep everyone happy. On weekends,
Central Park-the largest open place in New York-is closed to cars, and the roads may be used by bicycles only.
But "Bike for a Better City" says that this is not enough and keeps fighting to get bicycle lanes downtown. Until
that happens, the safest place to bicycles may be in the park.

     In the Caucasus Mountains, nearly 50 out of every 100,000 people live to celebrate their 100th birthday,
and many don't stop at 100! In American only 3 people in 100,000 reach 100. But these old people aren't alone.
The people who live high in the Himalaya Mountains and the Andes Mountains, seem to share the secret of long
life, too.
     First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days
of physical work as children and never seem to stop. For example, Mr. Rustam is 142 years of age. He has
experienced several wars. His wife is 116 years old. They have been married for 90 years. Mr. Rustam doesn't
want to stop his work as a farmer. "Why? What else would I do?" He asks. Oh, he has slowed down a bit.
Now he might work for 6 hours in the field instead of 10.
     Another factor (因素) that may contribute (有助于) to the good health of these people is their isolation.
Most of them are kept off the modern world. Inherited (遺傳的) factors also help. Most of the longest-lived
people had parents and grandparents who also reached very old ages. So good families genes (基因) may be
one factor in living longer.
     Finally, although these three groups don't eat exactly the same food, they eat little animal meat. Their diets
are full of fresh fruits, vegetables, nuts, grains, cheese and milk. They never eat more food than their bodies
need.

1. Which of the following contributes to the good health of all these long-lived people?

D. The Secret of Long Life

     One of the easiest ways to keep fit is to do jogging:"Jogging is the name for a very gentle (舒緩的) running-
it is just a little faster than walking."
     Start slow jog 20 meters, then walk 20 meters. Little by little, if you are not feeling very tired, you may do
more jogging and less walking. Finally, jog the whole way. It will be easy for you to start jogging for 15 minutes
twice a week, slowly, increase this to 20-30minutes everyday. The longer you join in jogging, the more you
enjoy it and the healthier you will become. Some people like jogging alone, and others enjoy doing it with friends.
