 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?

Dear guests, I’d like to talk to you today about renewable and non-renewable energy. Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world’s needs, but it is dangerous. The sun and the wind are other alternative sources of energy. The wind turns turbines to

make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.

1.How many types of energy sources are mentioned in the text? What are they?

2.What are the disadvantages of hydro and nuclear power?

3.Why do you think the wind and the sun are called alternative sources of energy?

4.What types of energy does Viet Nam use most?

5.What does the professor think Viet Nam will use more in the future?

Give the correct form of the word given to complete the sentences.

1. Tidal energy is renewable, _______________and clean. (plenty)

2. Wind will be used as an _______________friendly sources of energy. (environment)

3. There are many ways will be used to solve the problem of _____________. (pollute)

4. Solar power can be used to ______________or cool our houses. (hot)

5. __________________, fossil fuels are harmful to the environment. (fortunate)

6. We should use them______________ and try to find out alternative sources of power. (economy)

7. Solar energy is_________________, plentiful and clean. (renew)

8. I think that solar energy can be an________________ source of energy in the near future. (alter)

9. We should reduce the use of________________ at home. (electrical)

10. It’s a clean source of energy. Sailboats couldn’t move without this____________. (powerful)

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.
