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 immediately swims away. So it has lived up to now though it is not strong at all.

In 1993 an unknown American called Clarence Nash went to see the filmmaker Walt Disney. He had an unusual voice and he wanted to work in Disney’s cartoon(动画片) film for children. When Walt Disney heard Nash’s voice, he said “Stop! That’s our duck!”

The duck was the now-famous Donald Duck, who first appeared in 1934 in the firm The Wise Little Hen. Donald lived in an old houseboat(水上住家) and wore his sailor jacket and hat. Later that year he became a star after an eight – minute Mickey Mouse film. The cinema audience liked him because he was lazy and greedy(贪婪的), and because he lost his temper (发脾气) very quickly. And they loved his voice when he became angry with Mickey’s eight nephews(侄子). Soon Donald was more popular than Mickey Mouse himself, probably because he wasn’t a goody-goody like Mickey.

In the 1930S, ‘ 40s and ‘ 50s Donald and his friends Mickey, Goofy and Pluto made hundreds of Disney cartoons. He also made educational films about the place of the USA in the world, and safety in the home. Then in 1966 Donald Duck and his voice disappeared – there were no more new cartoons.

Clarence Nash died in February, 1985. But today’s children can still see the old cartoons on television and hear that famous voice.

阅读下列短文,根据短文中的信息完成文后表格。(每空一词)

In the past, man did not have to think about the protection of his environment. There were not many people on earth, and natural resources seemed to be unlimited.

   Today, things are different. The world has become too crowded. We are using up our natural resources too quickly, and at the same time we are polluting our environment with dangerous chemicals. If we continue like this, human life on earth will not survive.

   Everyone realizes today that if too many fish are taken from the sea, there will soon be none left. Yet, with modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, forests will disappear and nothing will grow on the land. Yet, we continue to use bigger and more powerful machines to cut down more and more trees.

   We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste products are still put into rivers or into the sea, and there are few laws to stop this.

   We know, too, that if the population of the world continues to rise at the present rate, in a few years, there will not be enough food.

What can we do to solve these problems?

If we eat more vegetables and less meat, we will easily get more food. Land that is used to grow crops can feed five times more people than land where animals are kept.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems, we shall have a better and cleaner living place in the future.
