VI. Read the passage and choose the correct answers. 

Fossil fuel such as coal, oil and gas has been the world’s main energy source for the past few centuries. Humans began using fossil fuel in the 18th century during the industrial revolution. Its popularity increased in the mid1900s and became our primary source of energy. Nowadays fossil fuel accounts for more than 80% of the world’s energy consumption. However, fossil fuel is running out not only because it’s a non-renewable source of energy but also because of human population growth. Scientists believe that at current rate we will only have enough fossil energy to use until 2088. Many developed countries in the meantime have been investing in scientific programs trying to find the best replacement for fossil fuel. 

1)1. What does the writer call fossil fuel in the passage?

A. Primary source of energy and non-renewable source of energy. 

B. Primary source of energy, non-renewable source of energy and fossil energy.

C. Fossil energy and non-renewable source of energy.

D. None are correct.

2)How much fossil fuel do people in the world consume today? 

A. All of fossil fuel in the world. 

B. 80% of fossil fuel in the world.

C. 4/5 of the world’s energy consumption.

D. ½ the world’s energy consumption. 

3. Why does fossil fuel run out?

A. Because it cannot be renewed.

B. Because more and more people use it and it cannot be renewed.

C. Because more and more people use it.

D. Because some scientists said so

4)What are many developed countries doing to solve the problem?

A. They are searching for new source of energy.

B. They are predicting the amount of fossil fuels.

C. They are studying some ways to renew fossil fuels.

D. They are advising people not to use fossil fuels.

5)5. Which of the following is NOT discussed in the passage?

A. Fossil energy has been mainly used since 18th century.

B. Fossil energy became popular in the mid-1900s.

C. Fossil fuel is believed to run out by 2088.

D. Fossil fuel can be replaced by another non-renewable source of energy.

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.

In Britain, natural gas is the most popular fuel for heating homes, and for cooking. It is piped all over the country from the gas fields below the North sea. Natural gas is used chiefly as a direct source of energy, although it is also used in the chemical industry. At the moment, the supply is plentiful, but it will be running short by the end of the century, and it will run out during the 21st century unless new supplies are found. We could do without natural gas, as coal gas can be used as...

We could do without natural gas, as coal gas can be used as a substitute, and there should be enough coal to last for several centuries. However, it is a form of energy which is not only cheap, but also highly efficient.
