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.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions

In the twentieth - century, people depend on unlimited energy to power their everyday lives. A wide range of energy-run devices and modern conveniences are taken for granted, and although it may seem that we will never be in danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly. Scientists are constantly searching for new sources of power to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend on the success of this search.

Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future are to be met without seriously harming the environment, existing alternative energy sources must be improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal power, as well as energy from new, nonpolluting types of fuels. 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 pose the daunting problem of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities located far from moving water. Harnessing energy from tides and waves has similar drawbacks. Solar power holds great promise for the future but methods of collecting and concentrating sunlight are as yet inefficient, as are methods of harnessing wind power.

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind, and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean, affordable energy for humanity's future.
