II/ Read the text and choose the best answers A, B, C or D. to the questions. (1m)

Most of the countries in the world have searched for alternative sources of energy 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 waste.

Experimental work is being done to derive synthetic fuels from coal, oil, shale and coal tars. But today that process has proven expensive. Other experiments are underway to harness power with giant windmills. Geothermal power heat from the earth is also being tested.

Some experts expect utility 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 five 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. The use of water productions for energy

B. Efficient ways of disposing of waste

C. The search for Alternative Sources of Energy

D. New Discoveries in Geothermal Power

2. Fifty years ago one third of the electricity in the United States was provided by_________.

A. wind B. waste products C. oil D. water

3. In the second paragraph, the phrase “synthetic fuels” could be best replaced by which of the following _________.

A. biological fuels B. artificial made fuels

C. low burning fuels D. fast burning fuels

4. Which of the following is NOT mentioned in the passage as an alternative source of energy?

A. electricity B. burning of garbage

C. geothermal power D. synthetics fuels

5. According to the author, the impracticability of using coal, oil shale and coal tars as sources of energy is due to _________.

A. their being money consuming B. their being time consuming

C. the scarcity of sources D. the lack of technology

Read the following passage, and then tick the correct answers : T or F.

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 saving coal, oil and gas before it is too late; and solar power is the only alternative.

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 natural resources. T

4. We should find out other types of energy besides fossil fuels. T

5. According to Professor Marvin Burnham, solar energy will be used as a form of alternative energy. F

SAVING THE ENVIRONMENT: ONE HOME AT A TIME Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things. First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it. Second, we need to watch the amount of water used in the home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth. Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing. If we do our part in our own homes, we can help keep the planet from becoming more polluted. Question 36: Pollution can be caused from the following sources EXCEPT______. A. water in rivers B. water from households C. wastes D. household chemicals Question 37: Recycling can help us ______. A. never cut down trees B. use products again and again C. place garbage bins easily D. produce more paper products Question 38: In order to save water, we can do all of the following things EXCEPT______. A. take short showers instead of baths B. repair leaky faucets C. fully use the washing machine D. turn the faucet off while brushing your teeth Question 39: Recycling helps to reduce waste because______. A. plants need to develop B. a person can do it in his home C. waste can be recycled and reused D. an average man produces compost for plants Question 40: The word "It" in paragraph 2 refers to ______. A. cutting down B. the number C. recycling D. effort
