VI. Read the passage and decide ì the sentence is True (T) or False (F). (1 pt)

       There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs – therefore we call them fossil fuels.

       Fossil fuels take millions of years to make. But they are not unlimited. We are using up the fuels that were made more than 300 million years ago. They are not renewable like solar power, wind power, hydro power or biomass. Once they are gone they are gone. So, it’s best not to waste fossil fuels.

       We can save fossil fuels by conserving energy. One simple way to do this is to turn off appliances, TVs and radios that we are not using. We can also turn off lights when no one is in the room. Another way is to go by bike or walk instead of driving cars or motorbikes.

* True (T) or False (F):

 

1. Three major forms of fossil fuels are oil, coal and natural gas.

2. They were formed right after the time of dinosaurs.

3. Once fossil fuels are gone, they will come back later.

4. Hydro power and biomass are non-renewable sources.

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...

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 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.
