Most of our electricity comes from the use of coal, oil, water power and nuclear power. We are looking for a cheap and clean source of power. Solar energy can be cheap and clean because it is available and it doesn’t cause pollution. One percent of the solar power that reaches the earth is enough to provide power for the total population. It is possible to store energy for a number of days, so solar energy can be used on cloudy days. Many countries in the world are beginning to use solar energy. By this way, we can save natural resources.

Many countries in the world are beginning to use solar energy. By this way, we can save natural resources.

Almost all our energy comes from oil, coal and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What would happen if there were no oil, coal and gas on earth? Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind and the water. Solar energy is unlimited. It supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperature of the planet. All are necessary for...

Almost all our energy comes from oil, coal and natural gas. We call them fossil fuels. The earth’s
fossil fuels are running out. What would happen if there were no oil, coal and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy
from the sun, the wind and the water.
Solar energy is unlimited. It supplies all the energy used to grow plants, to evaporate water for
rain, and to maintain the temperature of the planet. All are necessary for human life. If we’re able to
collect solar energy, we’ll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do other kinds
of work. In more recent time, wind power has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines.
Some early uses of water power were to mill grain, saw wood and power machinery for the textile
industry. Today water power is mostly used to generate electricity.
11. We are asking the question “What would happen if there were no oil, coal and gas on earth?” because ___.
A. we are now depending so much on fossil fuels.
B. we are looking forward to seeing great changes.
C. we are looking for other alternative sources of energy.
D. other sources of energy can come from the sun, the wind and the water.
12. Which of the following can NOT be used as alternative sources of energy?
A. coal/gas B. the sun/the water
C. the sun/the wind D. solar energy/nuclear power
13. Centuries ago, people used wind power to ___.
A. maintain the earth’s temperature B. get water from underground
C. grow plants D. generate electricity
14. Up till now, water energy has been used for ___.
A. similar purposes C. the textile industry
B. moving ships D. different purposes

15. The word “plentiful” in line 8 mostly means ___.
A. fresh B. natural C. available D. limited

Read the passage carefully, then choose the correct answer.

Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. 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 create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent

Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.

b. They are non renewable forms of energy

c. They are all very practical

d. They are inexpensive to exploit

5. From the passage, it can be inferred that to solve our energy problem...................

a. we will have to stop using many of our modern conveniences

b. scientists will have to find one major source of nonpolluting energy

c. scientists will have to find ways to increase our supplies of coal, oil, and gas
