Chọn chủ đề 2 Comparing Different Energy Sources
(So sánh các nguồn năng lượng khác nhau)
Giải thích: Đoạn văn đi so sánh lợi ích và bất lợi của một số nguồn năng lượng khác nhau.
Tạm dịch:
Lựa chọn tốt nhất cho năng lượng có thể khó khăn. Năng lượng từ than đá là dạng năng lượng phổ biến nhất hiện nay vì các nhà máy than không tốn kém để xây dựng. Các nguồn năng lượng không tái tạo khác như khí đốt tự nhiên, sạch hơn than đá, nhưng chúng vẫn không tốt cho môi trường. Các quốc gia hiện đang chuyển sang các nguồn năng lượng tái tạo như gió, mặt trời và thủy điện. Các nhà máy điện gió và năng lượng mặt trời sạch sẽ và rẻ để chạy, nhưng chúng không rẻ để xây dựng. Các nhà máy thủy điện cũng không gây ô nhiễm, nhưng chúng có thể tốn kém để xây dựng và ảnh hưởng đến môi trường bằng cách ngăn cá di chuyển tự do. Vì những lý do này, các quốc gia và thành phố thường chọn kết hợp các loại năng lượng.
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
1. Can natural resources be used up someday?
=> Yes, they can.
2. What should we do if we don’t want the natural resources to run out of?
=> We should use them economically and try to find out alternative sources of power
3. Why don’t people prefer using nuclear power?
=> Because it is very dangerous.
4. What does the radioactivity cause for young people?
=> It causes cancer and may badly affect the future generations.
5. What will you do to protect your environment?
=> I will use natural resources as economically as possible.
Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no coal, oil 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.
1. From which do plants on the earth get energy?
A. Stars
B. The Mars
C. The moon
D, The sun
2. What are the other words or phrase for fossil fuels?
A. Natural
B. Oil
C. Coal
D. Oil, gas, natural gas
3. Natural sources of energy are energy from..............
A. Wind
B. The sun
C. Water
D. The sun, wind, water
4. The word "abundant" in the passage is closet in meaning with............
A. Plentiful
B. Limited
C. Natural
D. Necessary

Fossil fuels are non -renewable energy soircecs.They include oil,coal,and natutal 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.
1)What are non-renewable energy sources?
Fossil fuels are non -renewable energy soircecs.
2)What can non-renewable energy soirces be used?
They can be used to create energy, generate electricity,or drive big machinery.
3)Why is hydro power limited?
Because dams cannot be built in certain areas
4)Can nuclear power provide enought electricity for the world´s needs?
Yes, it can

1. Natural resources can be used up some day
2. Try to find out alternative sources of power, use the natural resources as economically as possible, start conserving coal, oil and gas is what we should do if we don't want the natural resources to tun out of
3. Because it is very dangerous
4. Radioactivity cause cancer and may badly affect young people
5. I'll reuse old things, conserve water, plant trees and bike more to protect my environment
In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed. These include nuclear, water, solar, and wind power, as well as energy from new, (5) nonpolluting types of fuels types of fuels. Each of these, however, has advantages and disadvantages.
1. Solar energy (will use/ will be used/ will be using/ is used) in the world in the future.
2. (Wind/ Oil/ Coal/ Natural gas) power is renewable source.
3. The energy we use that produces carbon dioxide might create a big (non-renewable energy source/ renewable energy source/ carbon footprint/ fossil fuels)
4. "Non-renewable energy" means that it will (produce/ run out/ replace/create)
5. People put (plastics/ solar panels/ nuclear/ biogas) on the roof to catch the sun's energy.

Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resource? Look no further solar energy from the Sun
At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy thet reaches the Earth is enough to provide power for the total population
Many countries are already using solar energy. Solar panels are plaaced on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored a number of days, so or cloudy days you can use solar energy, too
Questions
1. Is the solar energy an effective source os power?
=>Yes,it is
2.Where are the solar panels placed?
=>They are placed on the roof of a house.
3.Is the solar energy used in Vietnam now?
=>Yes,it is
Read the passage below and an answer the question :
We can develop alternative sources of energy,and unless we'll never succeed.instead of burning fossil fuels we should be concentrating on more economic uses of electricity because electricity can be produced from any source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation than we can produce for the same money. Unless we do research on solar energy wind power tidal power hydroelectric plants.... Our fossil fuels will run out and we'll all freeze starve to dealth . Many countries are spending much more time and money on research because the energy from the sun the waves and the winds last forever.we really won't survive unless we start working on cleaner safer scour of energy .
