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 would happen if there were no oil, coal 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. It 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’re able to
collect solar energy, we’ll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do other kinds
of work. In more recent time, wind power 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 power were to mill grain, saw wood and power machinery for the textile
industry. Today water power is mostly used to generate electricity.
11. We are asking the question “What would happen if there were no oil, coal and gas on earth?” because ___.
A. we are now depending so much on fossil fuels.
B. we are looking forward to seeing great changes.
C. we are looking for other alternative sources of energy.
D. other sources of energy can come from the sun, the wind and the water.
12. Which of the following can NOT be used as alternative sources of energy?
A. coal/gas B. the sun/the water
C. the sun/the wind D. solar energy/nuclear power
13. Centuries ago, people used wind power to ___.
A. maintain the earth’s temperature B. get water from underground
C. grow plants D. generate electricity
14. Up till now, water energy has been used for ___.
A. similar purposes C. the textile industry
B. moving ships D. different purposes

4
15. The word “plentiful” in line 8 mostly means ___.
A. fresh B. natural C. available D. limited

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...

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

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

A. Low burning fuels B. Artificial made fuels

C. Biological fuels D. Fast burning fuels

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

Car: the burning of petroleum is one of the biggest sources of carbon monoxide that causes global warming. CO thins the ozone layer, which protects us from the sunrays. So try to walk, cucle, or use public transportation.

energy: the biggest use of home energy is for heating and cooling homes. it costs alot of money. so turn the heat down, especially at night. replace regular light bulbs with low energy light, which use less energy.

water: showers use a lot of water. buying a special " low-flow" shower head or taking shorter showers can cut this use in half

Many people still believe that natural resources will never be used up. Actually, the worlds 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.

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. 2.We don't know exactly how much fuel is left. 3. we shouldn't waste fuel 4. All people agree to use nuclear power as an alternative energy. 5. Natural resources should be used as much as possible.
