Mr.King works in a shop and drives a car for the manager. He drives carefully and can keep calm in time of danger. And he escaped from several accidents. The manager pays him more and the traffic policemen often speak highly of him.

Mr.Baker, one of his friends, works in a factory outside the city. It's far from his house and he has to go to work by bus. As the traffic is crowded in the morning, sometimes he's late for the work. His manager warns the young man that he will be sent away unless he gets to his office on time. He hopes to buy a car, but he hasn't enough money. He decides to buy an old one. He went to the flea (跳蚤) market and at last he chose a beautiful but cheap car. He said he wanted to have a trial (试验) drive, the seller agreed.

He called Mr. King and asked him to help him. Mr.King examined the car at first and then drove it away. It was five in the morning and there were few cars in the street. At first he drove slowly and it worked well. Then he drove fast. And when he reached a crossing, the lights turned red. He tried to stop it, but he failed and nearly hit an old woman who was crossing the street. A policeman told him to stop, but the car went on until it hit a big tree by the road. “Didn't you hear me?” the policeman asked angrily. “Yes, I did, sir.” said Mr.King, “Since it doesn't listen to me, can it listen to you?”

Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.

Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it quickly swims away. So it has lived up to now though it is not strong at all.
