A.
Each Indian tribe had a different language. Many Indians never learned any language except their own. Do you know how Indians from different tribes talked to each other? They had two ways to talk without sound. One way was by sign language; the other way by signals.
Sign language is a way of talking by using signs. Indians used sign language when they met strangers. In this way, they could find out whether the stranger was a friend or an enemy. In the Indian sign language, signs were made with the hands. One sign meant “man”. Another meant “horse”. To tell the time of day when something happened, an Indian pointed to the sky. He showed where the sun had been at the time.
Indians usually used signals when they wanted to send messages to someone far away. To make signals, an Indian might use a pony. He might use a blanket. Or he might use smoke, a mirror or fire arrows.
To signal that he had seen many animals, an Indian rode his pony in a large circle. Sometimes the Indian gave a signal like this and then went away to hide. This meant that there was danger.
The blanket signal was visible from far away. An Indian held the corners of a blanket in his hands. Then he began to swing the blanket from side to side in front of him. An Indian could send many different signals with his blanket.
He could also send many signals with a mirror. He usually used the mirror to warn someone of danger. Or he attempted to get the attention of a person far away. But he also used it to send messages in code. Of course, mirrors could be used only when the sun was shining. At night, Indians used fire arrows for signaling.
   An Indian also sent signals with smoke. He made a small fire of dry wood. Then he put grass or green branches on it. He held a blanket over the fire for a minute. When he removed the blanket from the fire, there was a cloud of smoke. The number of clouds of smoke told his message in code.
Now you can see that Indians didn’t need to learn each other’s language. They could talk to one another by using signals or sign language.

People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man's release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance , such as oil tankers into the sea.

  The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produce there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used in some cases, too heavily, and artificial fertilizer cannot restore the balance.

   Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in term of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying ,excess consumption and careless disposal of the products we use in our daily lives.

A. dealt with               B. exposed

6. In the writer’s view ,the more new goods, _______.

A. the less pollution             

   B. the harder pollution can be prevented

C. the more pollution there will be

D. the more easily pollution can be controlled

7. What can we learn from the last paragraph?

A. We can do much to reduce pollution.

B. The government is trying hard to stop pollution.

C. Individuals know how to get rid of the habit of littering everywhere.

D. We can’t stop buying unnecessary things.

8. People can help solve the problem of pollution by _______.

A. urging their governments to control litter and waste
