Read the text below and choose the answer (A, B, C, or D) which you think fits best
according to the text (10p):
Today we take electricity for granted and perhaps we do not realize just how useful this
discovery has been. Steam was the first invention that replaced wind power. It was used to
drive engines and was passed through pipes and radiators to warm rooms. Petrol mixed with air
was the next invention that provided power. Exploded in a cylinder, it drove a motor engine.
Beyond these simple and direct uses, those forms have not much adaptability.
On the other hand, we make use of electricity in thousands of ways. From the powerful
voltages that drive our electric trains to the tiny current needed to work a simple calculator, and
from the huge electric magnet in steel works that can lift 10 tons to the tiny electric magnet in a
doorbell, all are powered by electricity. An electric current can be made with equal ease to heat
a huge mass of molten metal in a furnace, or to boil a jug for a cup of coffee.
Other than atomic energy, which has not as yet been harnessed to the full, electricity is the
greatest power in the world. It is flexible, and so adaptable for any task for which it is wanted.
It travels so easily and with incredible speed along wires or conductors that it can be supplied
instantly over vast distances.
To generate electricity, huge turbines or generators must be turned. In Australia they use
coal or water to drive this machinery. When dams are built, falling water is used to drive the
turbines without polluting the atmosphere with smoke from coal. Atomic power is used in
several countries but there is always the fear of an accident. A tragedy once occurred at
Chernobyl, in Ukraine, at an atomic power plant used to make electricity. The reactor leaked,
which caused many deaths through radiation.
Now scientists are examining new ways of creating electricity without harmful effects to
the environment. They may harness the tides as they flow in and out of bays. Most importantly,
Page 1 of 6


they hope to trap sunlight more efficiently. We do use solar heaters for swimming pools but as
yet improvement in the capacity of the solar cells to create more current is necessary. When this
happens, electric cars will be viable and the world will rid itself of the toxic gases given off by

trucks and cars that burn fossil fuels.
21. The author mentions the sources of energy such as wind, steam, petrol in the first
paragraph to ______.
A. suggest that electricity should be alternated with safer sources of energy
B. emphasize the usefulness and adaptability of electricity
C. imply that electricity is not the only useful source of energy
D. discuss which source of energy can be a suitable alternative to electricity
22. Before electricity, what was sometimes passed through pipes to heat rooms?
A. Gas.
B. Petrol.
C. Steam.
D. Hot wind.
23. What does the author mean by saying that electricity is flexible?
A. It is cheap and easy to use.
B. It is used to drive motor engines.
C. It can be adapted to various uses.
D. It can be made with ease.
24. What do we call machines that make electricity?
A. Voltages.
B. Electric magnets.
C. Generators or turbines.
D. Pipes and radiators.
25. The main forms of power used to generate electricity in Australia are ______.
A. atomic power and water
B. water and coal
C. sunlight and wind power
D. wind and gas
26. The word "they" in the last paragraph refers to ______.
A. harmful effects
B. the tides

C. scientists
D. new ways
27. Electric magnets are used in steel works to ______.
A. lift heavy weights up to ten tons
B. test the steel for strength
C. heat the molten steel
D. boil a jug of water
28. The advantage of harnessing the power of the tides and of sunlight to generate electricity is
that they ______.
A. do not pollute the environment
B. are more reliable
C. are more adaptable
D. do not require attention
29. Which of the following power sources causes pollution by emitting harmful gases?
A. Sunlight.
B. Petrol.
C. Water.
D. Wind.

A. “Types of Power Plants”
B. “Electricity: Harmful Effects on Our Life”
C. “How to Produce Electricity”
D. “Why Electricity Is So Remarkable”
