Tạm dịch bài đọc:
Chào cả lớp. Hôm nay tôi muốn nói với các bạn về hai nguồn năng lượng. Chúng là những nguồn không thể tái tạo và những nguồn có thể tái tạo.
Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. Chúng ta có thể sử dụng những nguồn này để sản xuất năng lượng. Chúng rẻ và dễ sử dụng. Mọi người sử dụng chúng rất nhiều. Nhưng chúng rất hạn chế và sẽ hết sớm.
Các nguồn tái tạo đến từ mặt trời, gió hoặc nước. Khi năng lượng đến từ mặt trời, chúng ta gọi nó là năng lượng mặt trời. Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước. Nguồn tái tạo có sẵn, sạch sẽ và an toàn để sử dụng. Nhưng chúng đắt tiền để sản xuất.
Trong tương lai, chúng ta sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.
1. Nguồn không tái tạo được rẻ và _________.
A. có sẵn
B. dễ sử dụng
C. đắt
2. ________nhận được từ mặt trời, gió hoặc nước.
A. Nguồn tái tạo
B. Tất cả các nguồn năng lượng
C. Các nguồn không thể tái tạo
3. Khi năng lượng đến từ nước, chúng ta gọi nó là_________.
A. năng lượng gió
B. năng lượng mặt trời
C. năng lượng thủy
4. Các nguồn năng lượng tái tạo tốt hơn cho ____.
A. môi trường
B. xe của chúng tôi
C. năng lượng thủy
1. B
Non – renewable sources are cheap and easy to use.
(Năng lượng không thể tái tạo thì rẻ và dễ sử dụng.)
Thông tin: Non-renewable sources are coal, oil and natural gas. ... They are cheap and easy to use.
(Các nguồn không thể tái tạo là than đá, dầu mỏ và khí đốt tự nhiên. ... Chúng rẻ và dễ sử dụng.)
2. ARenewable sources come from the sun, wind or water.
(Các nguồn năng lượng có thể tái tạo đến từ mặt trời, gió và nước.)
Thông tin: Renewable sources come from the sun, wind or water.
(Các nguồn tái tạo đến từ mặt trời, gió hoặc nước.)
3. C
When energy comes from water, we call it hydro energy.
(Khi năng lượng đến từ nước, chúng ta gọi nó là năng lượng thủy điện.)
Thông tin: Wind energy comes from the wind, and hydro energy comes from water.
(Năng lượng gió đến từ gió, và năng lượng thủy điện đến từ nước.)
4. A
Renewable energy sources are better for the environment.
(Các nguồn năng lượng có thể tái tạo thì tốt hơn cho môi trường.)
Thông tin: In the future we will rely more on renewable energy sources. They are better for the environment and they will not run out.
(Trong tương lai, chúng tôi sẽ dựa nhiều hơn vào các nguồn năng lượng tái tạo. Chúng tốt hơn cho môi trường và chúng sẽ không cạn kiệt.)
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.

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

We are looking for cheap, clean, and effective sources of energy. These types of energy won’t cause pollution or waste natural resources. It will be provided freely by the sun. One percent of the solar energy that reaches the earth will be enough to provide electricity for the whole population of the world. Solar energy will be used by many countries around the world. Solar panels will be placed on the roofs of houses and other buildings and the sun’s energy will be used to heat water. The energy will be stored for a long time. We hope that by using solar energy the problem of the energy shortage will be solved.
1. What types of energy are we looking for?
_We are looking for cheap, clean, and effective sources of energy
2. What will we use the sun’s energy for?
_____ The sun’s energy will be used to heat water
3. How long will the energy be stored?
__________The energy will be stored for a long time
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 - d: solar energy – the sun
(năng lượng mặt trời – mặt trời)
2 - c: wind energy – wind
(năng lượng gió – gió)
3 - a: hydro energy – water
(năng lượng thủy điện – nước)
4 - b: nuclear energy – nuclear
