II. READING
1. Work in pairs.:
1. Work in pairs. Discuss the following questions 1. What are the main sources of energy in Viet Nam 2. What types of energy sources will be used in the future? coal , oil, hydro power, … solar energy , wind energy ….. 2. Read the text below and check your ideas .:
2. Read the text below and check your ideas Professor Glaton is preparing a speech about renewable and non-renewable energy. Dear guests, I`d like to talk to you today about renweable and non-renewable energy. Fossil fuel 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. Read the text below :
2. Read the text below and check your ideas 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. 3. Read the text then match and answer the questions:

b. Answer the questions .:
b. Answer the questions. 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? Number 1:
1. How many types of energy sources are mentioned in the text? What are they? Number 1 ==> Two. They are renewable and non-renewable . Number 2:
2. What are the disadvantages of hydro and nuclear power? Number 2 ==> Hydro power is limited because dams cannot be built in certain areas, and nuclear energy is dangerous . Number 3:
3. Why do you think the wind and the sun are called alternative sources of energy? Number 3 ==> Because the wind can turn turbines to make electricity. Solar energy can be changed into electricity or can be used to heat or cool our houses . Number 4:
4. What types of energy does Viet Nam use most? Number 4 ==> We use hydro power most. Number 5:
5. What does the professor think Viet Nam will use more in the future? Number 5 ==> He think Viet Nam will use the wind and the sun as alternative sources of energy in the future. III. SPEAKING
4. Work in pairs:
4. Ask and answer questions about the advantages and disadvantages of each type of energy source. Example : Student A: What type of energy is oil ? Student B: It is non-renewable source of energy, because it cannot easily be replaced . Student A: What are its advantages and disadvantages ? Student B: It can be used to drive machinery, but it also pollutes the environment. - Nuclear power:
4. Ask and answer questions about the advantages and disadvantages of each type of energy source. - Nuclear power Student A: What type of energy is nuclear power ? Student B: It is renewable source of energy, because it can be replaced . Student A: What are its advantages and disadvantages ? Student B: It can provide enough electricity for the world`s needs, but it is dangerous. - The sun and the wind:
4. Ask and answer questions about the advantages and disadvantages of each type of energy source. - The sun and the wind Student A: What type of energy are the sun and the wind? Student B: They are other alternative source of energy. Because they`re unlimited. Student A: What are its advantages and disadvantages ? Student B: Solar energy can be converted into electricity. Tee wind turns turbines to make electricity. But they`re so expensive. 5. Talk about the advantages and disadvantages of each type of energy source :
5. Talk about the advantages and disadvantages of each type of energy source Example : Hydro power is a renewable source of energy because it comes from water. It is cheap and plentiful. Unfortunately, dams can only be built in certain areas . THE END
