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

There are nine planets in our solar system. These planets each have their atmosphere and environmental conditions. Scientists have been trying to research other planets to see if it is possible for life to exist on the other eight own bodies in space.
Mercury and Pluto are probably the most difficult to research because of their position in the solar system. Mercury is so close to the sun that with our current technology a space shuttle would burn up before it even reached its atmosphere. Pluto is so far away that some scientists believe that it may not even be a planot but a large asteroid or comet. A space shuttle can not trave that far away because it is so far away from the sun that it would freeze.
Many scientists also believe that our solar system is not alone in the uni- with us. It is difficult to know if there is life present elaewhere in the universe. for many years to come. yerse.

One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.

True or False sentence:

1....................Solar energy can be cheap and clean.

2....................Most of our electricity now comes from nuclear power.

3....................the solar energy that gets to the Earth cannot provide enough power for the world's population.

4....................Solar energy can be used on cloudy days.

5....................All buildings in Sweden will be heated by solar energy in 2050.
