	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 do not approve of using nuclear power because it’s very dangerous. What would happen if there was 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 economical as possible.
1. Natural resources will never run out.
2. We don’t know exactly how much fuel is left.
3. We shouldn’t waste fuel.
4. According to Professor Marvin Burnham, solar energy will be used as a substitute for natural resources.
5. All people agree to use nuclear power as an alternative energy.
6. Radioactivity from nuclear power causes cancer and may have bad effect on the future generations.
7. Natural resources should be used as much as possible.
4. My family used to be having dinner at 7 o’clock in the evening
5. I wish I can go with you to the countryside next weekend

X. Read the passage, DO some tasks
Almost all our energy comes from oil, coal, and natural gas. We call them fossils fuel. The earth’s fossil fuels are running out. What will happen when there are no oil, coal, 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.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy from the wind has been used for centuries to move ships, grind grain, pump water and do other forms of work. In more recent times, wind has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines. Some early uses of water power were mill grain, saw wood, and power machinery for the textile industry. Today water is mostly used to generate electricity.
