Read the passage below and choose one correct answer for each question:
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 will happen when there is no coal, oil 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. The sun 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 are able to collect solar energy, we will be sure to have this
abundant source of power.
Another source of energy from nature is the wind which is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do
other forms of work. In recent time, wind 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 were to mill grain, saw wood and power machinery
for the textile industry. Today water is mostly used to generate electricity.
