Part 3. Read the following passage and answer the questions that follow. Circle A, B, C or D to indicate your answers. (1.0 point)
The search for alternative sources of energy has led in various directions. Many communities are burning garbage and other biological waste products to produce electricity. Converting waste products to gases or oil is also an efficient way to dispose of wastes.
Experimental work is being done to derive Synthetic fuels from coal, oil shale and coal tars. Other experiments are underway to harness power with giant windmills. Geothermal power is also being tested.
Some experts expect companies to revive hydroelectric power derived from streams and rivers. Fifty years ago hydroelectric power provided one
third of the electricity used in the United States, but today it supplies only four percent. The oceans are another potential source of energy. Scientists are studying ways to convert the energy of ocean currents, tides and waves to electricity. Experiments are also underway to make use of the temperature differences in ocean water to produce energy.
1. Which is the best title of the passage?
A. New Discoveries in Geothermal Power.
B. The Use of Water Production for Energy.
C. The Search for Alternative Sources of Energy.
D. Efficient Ways of Disposing of Waste.
2. Fifty years ago one third of the electricity in the United States was provided by...

4. Which of the following is NOT mentioned in the passage as an alternative source of energy?
A. Synthetic fuels B. Burning of garbage C. Geothermal power D. Electricity
5. According to the author, the impracticality of using coal, shale oil and coal tars as sources of energy is due to...
A. the lack of technology B. the scarcity of sources
C. their being money consuming D. their being time consuming
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 .!!! )
