Read the following passage and decide if it is True or False

   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 Burnharm of the New England Institude 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.

According to Professor Marvin Burnham, solar energy will be used as a substitute for natural resources. ___________

Exercise 1 : Read the following passage carefully and decide whether these statement below are T (true) or F (false) and translate to Vietnamese

Energy is fundament to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas with which their life can be improved.

People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps the problem of indoor air pollution. Moreover, it's made from plant waste and animal manure, They cost almost nothing.

The endency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running out. In the future, the wind and the sun will be uses as the most important environmentally friendly energy sources.

T or F

1. Non-renewable sources are being used up

2. Many poor people in developing countries do not have little electricity

3. Biogas is a new source of energy available for poor people

4. Biogas creates a lot of smoke

5. The new energy source is not costly
