X Read the passage and answer the questions given.
Many people still believe that natural resources will never be used up. Actually the world’s energy resources are limited. Nobody knows exactly how much fuel is left. However, we also should use them economically and try to find out alternative sources of power. According to Professor Marvin Burnham of the New England Institute of Technology, we have to start conserving coal, oil and gas before it is too late; and nuclear power is the only alternative.
However, many people don’t approve of using nuclear power because it is very dangerous. What would happen if there were a serious nuclear accident? Radioactivity causes cancer and may badly affect the future generations. The most effective thing is that we should use natural resources as economically as possible.
Answer the questions:
1. Can natural resources be used up someday?
.......................................................................................................................
2. What should we do if we don’t want the natural resources to run out of?
.......................................................................................................................
3. Why don’t people prefer using nuclear power?
.......................................................................................................................
4. What does the radioactivity cause for young people?

5. What will you do to protect your environment?
.......................................................................................................................
III. Use the cues given to write correct sentences. 1. At present/ most/ our electricity/ come/ use/ coal, gas, oil or nuclear power. At present most of our electricity come from the use the coal, gas, oil or nuclear power. 2. Scientists/ try/ find/ other alternative sources/ energy. Scientists try to find out other alternative sources like energy. 3. energy / from / sun / be / clean / cheap/ safe /. The energy comes from the sun is clean. cheap and safe.
