1.How many types of energy sources are mentioned in the text? What are they?
Two. They are renewable and non-renewable.
2.What are the disadvantages of hydro and nuclear power?
Hydro power is limited because dams cannot be built in certain areas. Nuclear power is dangerous.
3.Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of power and we use them instead of non-renewable sources to get the electricity we need.
4.What types of energy does Viet Nam use most?
We use non-renewable sources of energy the most but we are increasingly using hydro power.
5.What does the professor think Viet Nam will use more in the future?
He thinks Viet Nam will use the wind and the sun as alternative sources of energy in the future
2. Mr Lam is giving a lecture on energy sources. Read the text and choose the best option (A, B, or C) to complete the sentences.
(Ông Lâm đang giảng bài về các nguồn năng lượng. Đọc văn bản và chọn phương án tốt nhất (A, B hoặc C) để hoàn thành các câu.)
Hello, class. Today I'd like to tell you about two energy sources. They are non-renewable sources and renewable sources.
Non-renewable sources are coal, oil and natural gas. We can use these sources to produce energy. They are cheap and easy to use. People use them a lot. But they are very limited and will run out soon.
Renewable sources come from the sun, wind or water. When energy comes from the sun, we call it solar energy. Wind energy comes from the wind, and hydro energy comes from water. Renewable sources are available, clean and safe to use. But they are expensive to produce.
In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.
1. Non – renewable sources are cheap and _________.
A. available
B. easy to use
C. expensive
2. _________come from the sun, wind or water.
A. Renewable sources
B. All energy sources
C. Non-renewable sources
3. When energy comes from water, we call it_________.
A. wind energy
B. solar energy
C. hydro energy
4. Renewable energy sources are better for_______.
A. the environment
B. our cars
C. hydro energy
VI . Read , answer the questions . 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 .

it is dangerous
5. Why are the wind and the sun called alternative sources of energy ?
Because the wind turns turbines to make electricity . Solar power can be converted into electricity . It can be used to heat or cool our houses
6. Will the wind and the sun be valued more and more in the future in Viet Nam
Yes, they will
Read the following passage and decide if it is T or F 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 allternative sources of power. According to Professor Marvin Burnharrm of the New England Institude of Technology, we have to start conserving coal, oil and gas before it is too late; and solar power is the only alternative.
1. We don't know how much fuel is left .......T...........
2. According to Professor Marvin Burnharrm , solar energy will be used as a form of alternative energy.......F.............
