Our environment is in trouble. People and industries are polluting the air, rivers, lakes and seas. There are many things you can do to help the environment. Here are a few.

Firstly, the burning of petroleum is one of the biggest sources of carbon monoxide (CO) that causes global warming. CO thins the ozone layer, which protects us from the sun’s ray. So try to walk, cycle or use public transportation.

Secondly, the biggest use of home energy is for heating and cooling homes. It not only consumes much energy but also costs a lot of money. So turn the heat down, especially at night. Replace ordinary light bulbs with energy-saving light bulbs, which use less energy.

Finally, showers use a lot of water. Buying a special “low-flow” shower head or taking shorter showers can cut this use in half.

25.We can do nothing to help the environment.

26.Carbon monoxide comes from burning of petroleum.

27. The more petroleum we burn, the better the environment is.

28. Energy is used to heat and cool homes.

29. The passage mainly discusses:

a. The source of CO

b. Energy-saving bulbs

c. The ozone layer

d. Some ways to protect the environment

30. The word “ordinary” in line 6 is closest in meaning to the word:

a. modern b. cheap c. effective d. normal

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.

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....................Solar energy can be cheap and clean.

2....................Most of our electricity now comes from nuclear power.

3....................the solar energy that gets to the Earth cannot provide enough power for the world's population.

4....................Solar energy can be used on cloudy days.

5....................All buildings in Sweden will be heated by solar energy in 2050.

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
