A Train Floating On Air

A train that floats on air? It's not magic―it's magnets (磁). And it's close to reality.

       In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus. In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power. And in China, a magnet train line linked Shanghai with nearby Pudong Airport.

These trains use magnetic levitation (悬浮) technology, “maglev” for short. They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles repel each other.

How does it work?

Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet-filled guiding way. With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past.

When an electrical current is sent through the track, the train moves. Turn the current backwards and the train slows down.

Maglev doesn't rely on the friction (摩擦力) of wheels on track, so it can climb a much steeper hill than a traditional train. And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop.    

This passage is about __________.

  A. maglev                 B. magnets                   C. levitation                  D. electricity

  B. Instead of electricity, magnets are used as the power of a maglev.

  C. Maglev trains can climb hills with the help of magnet wheels.

  D. Electric currents decide the movements of a maglev train. 

What is the difference between a maglev train and an ordinary train?

  A. A maglev train can climb mountains without power while an ordinary one can’t.

  B. A maglev train can travel in college campus while an ordinary train is not allowed.

C. Travelling without a track, a maglev train is safer and smoother than an ordinary one.

  D. Floating on a track, a maglev train is faster, quieter than an ordinary railway train.

It’s obviously true that not all people like to work, but everyone likes to play. All over the world, men and women, young and old, enjoy recreational activities. So, beyond doubt, entertainment plays an important role in our daily lives. In modern society, there is a broad range of recreational activities—from online computer games to lovely picnics—that meet the needs of different groups of people. Therefore, it won’t be difficult for you to find some recreation to refresh your body and mind.

Recreational activities have a number of benefits, especially in this highly competitive society. They can help us relax, have fun and relieve stress. In fact, I believe there is no better way to get exercise and relieve stress than to take an active part in recreational activities. But can recreational activities do us harm? Of course they can. Let’s take TV as an example. There is no denying that TV offers access to the latest news and to useful knowledge, while providing us with entertainment. However, if we spend too much time watching TV, it will numb our mind and destroy our creativity, which is exactly the opposite of what we really want. What’s more, TV can also show some pornographic programs, which are absolutely unsuitable for us young students. So, just as the old saying goes, every coin has two sides, and watching TV is no exception.

As a student, I think recreational activities are very important for us. But this doesn’t mean we should take up whatever recreational activities are available. Instead, we should strike a balance between work and rest. We should have our own judgment, which means knowing what is good for us and what is not. And we should exercise self-control so as not to become addicted to them. I believe moderate recreational activity will benefit us in many ways and help us live a full, meaningful life.

Why does entertainment play an important role in people’s daily lives?

A. Because online computer games are popular with people.

B. Because entertainment can help people have fun instead of relieving stress.

C. Because people of all ages enjoy recreational activities.

D. Because it is easy and convenient to take up any recreational activity.

Which of the following statements is not counted as the disadvantage of TV?

A. People are addicted to watching TV.

B. TV provides people with the latest news.

C. Some programs are unsuitable for young students.

D. Spending too much time on it may destroy people’s creativity

In the author’s opinion, what is the proper attitude to recreational activities?

A. Spending as much time as we like watching TV.

B. Taking part in any recreational activities available.

C. Learning to control ourselves about entertainment.

D. Benefiting us by taking part in different activities.

There is an English saying , “Laughter is the best medicine.” ____ Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.

Tests were carried out to study the effects of laughter on the body. People watched the funny films while doctors checked their heart, blood pressure, breathing and muscles. _____ It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.

_____ In one experiment, doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍受) the pain for the longest time was the groups which listened to a funny programmes.  ______

In this way ______ they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish (减少) both stress and pain.

Until recently, few people took the saying seriously.

Laughter and physical exercise have similar effects on the human body.

It was found that laughter has similar effects to physical exercise.

As a result of these discoveries, some doctors in the United States now hold laughter clinics.

Laughter could produce a kind of chemical.

Other tests have shown that laughter appears to be able to reduce the effect of pain on the body.
