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.

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 )

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
True/ False sentence:
1. Natural resources will never run out. F
2.We don't know exactly how much fuel is left. T
3. we shouldn't waste fuel F
4. All people agree to use nuclear power as an alternative energy. F
5. Natural resources should be used as much as possible.F
1. Natural resources will never run out. F

Are you looking for a cheap. clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.
True or False sentence:
1...........T.........Solar energy can be cheap and clean.
2........F............Most of our electricity now comes from nuclear power.
3..........F..........the solar energy that gets to the Earth cannot provide enough power for the world's population.
4..............T......Solar energy can be used on cloudy days.
5...........T.........All buildings in Sweden will be heated by solar energy in 2050.
