Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no coal, oil and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.
Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.

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?
