Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so no new space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages. Wind and water power rely on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they...

Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun! Solar cells can easily be installed on house roofs, so no new space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages. Wind and water power rely on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime. However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cells require large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy

40. What does the word advantages in line 13 mean?

A. very bad B. resources C. benefits D. friendly

II. Read the following passage and choose the correct answer.
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
waste.
Experimental work is being done to derive synthetic fuels from coal, oil shale and coal tars.
But to date, 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 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. Efficient Ways of Disposing of Waste B. The Use of Water Productions for
Energy
C. The Search for Alternative Sources of Energy D. New Discoveries in Geothermal Power
2. In the second paragraph, the phrase “synthetic fuels” could best be replaced by which of
the following?
A. Biological fuels B. Low burning fuels C. Fast burning fuels D. Artificial
made fuels
3. Which of the following is NOT mentioned in the passage as an alternative source of
energy?
A. Burning of garbage B. Geothermal power C. Synthetic fuels
D. Electricity
4. According to the author, the impracticability of using coal, oil shale and coal tars as
sources of energy is due to ___________ .
A. their being time consuming B. their being money consuming

C. the scarcity of sources D. the lack of technology their being
money consuming
5. The word “it” in the last paragrph refers to ____.
A. alternative source B. the United States C. hydroelectric power D. Electricity
6. What can be inferred from the last paragraph?
A. Hydroelectric power will be the main source of energy
B. Synthetic fuels will be the principal source of alternative energy
C. Alternative energy will come from a variety of sources
D. All alterenative production of energy will be delivered from water.

Special devices have already been made avaible to put on the roofs of houses and flats to (1) catch the sun's rays and the thus heat water. Thousands (2) of these devices are now being used to provide (3) energy in homes throughout the United States while more (4) than a million solar water-heating units have already been (5) built in home in Japan. Other purposes for which (6) solar energy is at present being used include the separation of salt from seawater, irrigation and sewage disposal (7) for most people in developing countries, the need is not for air-conditioners or central heating but for cheap (8) ways of cooking food, drying crops and lighting homes
