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.

61.   Which of the following is a repelling action?

62.   What can we learn from the text?

         A. A magnet-filled guiding way is formed inside a maglev train.

         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. 

63.   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.

I went to Beijing this National holiday, and it was an interesting experience of my life.

My friends told us that taking the “hard   16 ” to Beijing would be really terrible. So we didn’t know what to   17 . But we were pleasantly surprised when we finally boarded the   18 , which was relatively modern and   19 . During the 14-hour ride we ate peanuts and talked. It was not   20  at all.

It was morning when we arrived. We stepped out of the railway station, having sat in hard seats and not getting much   21 . However, we had energy. First, we tried to get return tickets to Shanghai, but the tickets seller   22  us that tickets would not be on   23  for another two days. We were a little worried about getting   24  , but we made up our minds to   25  for the hotel to put our bags down. After fighting our way   26  the “gypsy” taxi driver who tried to   27  one hundred yuan for the ride, we found another taxi and it   28  cost us thirty yuan to get   29  we had planned to go. When we reached the hotel, there was a window for airplane and train tickets.   30 , the man behind the counter could get tickets that day, which we   31 . The most important lesson about China I ever   32  is to get someone to do your work for you, and it seems to work out much   33 . We were not able to get tickets, but the   34  agents could.

While in Beijing we saw a lot of places of interest, most of which were very   35 . It was fun to be with thousands of people in one place. There aren’t any words to describe it.

A

One evening a police officer was driving slowly along a road. He was off duty and was wearing plain clothes.

Suddenly he saw two men running out of a building. He heard someone shouting, “Help! Help! Stop thief!” The police officer was sure that the two men were thieves. He knew he must arrest them. However, he was not only out of uniform (制服) but also unarmed (没有带枪). He knew if he got out of his car and tried to arrest them, at least one of the men would easily escape. The police officer was facing a difficult problem. He knew that he mustn’t let the men escape, but how could he arrest them?

He thought quickly and had an idea. It involved danger and it might not work, but he decided to try.

He drove his car up to the men and stopped beside them. Then he put his head out of the window and asked, “Do you want a lift?”

“Yes, yes,” the men answered, and quickly got into his car. “Please take us to the railway station,” they told him.

“Very good,” the police officer said and drove off. After a few minutes, one of the men cried out, “But this isn’t the way to the railway station. Where are you going?” “I must go this way,” the police officer explained. “There’s a big fire and the traffic is held up. You don’t want to sit in a traffic jam, do you?”

“No, no,” the men agreed. “Please take us the quickest way.”

The next moment, the police officer had pulled up at the police station. He jumped out, shouted for help, and seconds later the two thieves were arrested.

61. How did the police officer decide to try to arrest the two thieves?

A. By telephoning the police for help.

B. By letting them get into his car.

C. By going back to the police station for his gun.

D. By asking people around to help him.

62. The underlined word “involved” means “        ”.

A. developed         B. offered         C. stopped        D. caused

63. Why did the police officer tell the two thieves to get into his car instead of going to catch them directly?

A. He was afraid he would be beaten by them.

B. He was afraid they would recognize him.

C. He was afraid one of them would escape.

D. He was afraid they would not escape.

64. Soon after the two thieves got into the car they found out that ________.

A. they were not on the way to the railway station

B. the police officer was taking them to the police station

C. they were on the way to the airport

D. they were caught by the policeman
