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. Another source of energy from nature is the wind which is clean and plentiful. Energy from the wind has been used for centuries to move ships, grind grain, pump water and do other forms of work. In recent time, wind has been used to generate electricity. Water can also provide power. For a long time, people have used water to power machines. Some early uses of water were to mill grain, saw wood and power machinery for the textile industry. Today water is mostly used to generate electricity.
28. The fossil fuels on earth are .......................

29. Solar energy means the power from the .............................
A. fossil fuel B. temperature C. electricity D. sun
30. The word “abundant” in the passage is closest in meaning to ............................
A. necessary B. limited C. plentiful D. natural
31. Centuries ago, people used wind power to ...........................
A. get water from underground B. grow plants C. maintain the earth’s temperature D. generate electricity
32. Nowadays water energy is mainly used to ................................
A. power machine B. mill grain C. saw wood D. generate electricity
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 do not approve of using nuclear power because it's very dangerous. What would happen if there was 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 economical as possible

Dịch: Nhiều người vẫn tin rằng tài nguyên thiên nhiên sẽ không bao giờ được sử dụng hết. Trên thực tế, tài nguyên năng lượng của thế giới rất hạn chế. Không ai biết chính xác còn lại bao nhiêu nhiên liệu.
Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.
1. Coal, oil and natural gas .............
a. are very great in amount
c. pollute the atmosphere
b. will never be used up
d. supply most of its power
( Mk đã chú thích bằng cách in đậm key word/ sentense ở trên đoạn văn nhé.!!! )
2. Nuclear power plants
a. are difficult to build ..............
c. are very cheap to maintain
b. pollute the atmosphere
d. create the problem of nuclear waste
( Câu a,c ko đúng vì phía trên họ nói là they are costly to build and maintain : Chúng thì quá là đắt đỏ để mà xây dựng và duy trì ; còn câu c thì phía tren họ nói là without polluting the atmosphere : ko hề gây ôi nhiễm tới không khí. )
3. Wind power...............
a. cannot be used in places that has strong wind
b. is never completely used up
c. is a source of pollution
d. cannot replace itself .
( Câu này hơi khó hơn, mk phải dịch một chút Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind: Năng lượng gió là nguồn năng lượng tái tạo không ô nhiễm nhưng nó không thể được sử dụng nhiều nơi trên thế giới, những nơi mà không có đủ gió. )
4. What is the advantage of these alternatives?
a. They are environmentally friendly energy sources
b. They are non renewable forms of energy
c. They are all very practical
d. They are inexpensive to exploit
( Bn xem mấy câu mk đánh dấu trên đoạn nha trong câu đó sẽ có key words/ sentences cho đáp án nha .!!! )
5. From the passage, it can be inferred (suy ra) that to solve our energy problem...................
a. we will have to stop using many of our modern conveniences
b. scientists will have to find one major source of nonpolluting energy
c. scientists will have to find ways to increase our supplies of coal, oil, and gas
d. a combination of conservation and invention will be needed
(Cái này nằm ở đoạn cuối : Conservation efforts coupled with renewable energy resources will ensure supplies of clean, affordable energy for humanity's future : Sự nỗ lực bảo tồn cùng với các nguồn năng lượng tái tạo sẽ đảm bảo nguồn cung cấp năng lượng sạch, giá cả phù hợp cho tương lai của toàn nhân loại )
Tick cho mk nha!!!
1. It's from the gas fields below the North sea.
