Are you looking for a cheap. clean, effective source of power that doesnt cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. 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...

Are you looking for a cheap. clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. 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.
II/ Read the passage and answer the question :
Air pollution is a serious problem in many cities. Motor vehicles, factories and other source create so
much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the
people who live in cities. City wastes cause water pollution when they are poured into the waterways.
These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have

II/ Read the passage and answer the question :
Air pollution is a serious problem in many cities. Motor vehicles, factories and other source create so
much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the
people who live in cities. City wastes cause water pollution when they are poured into the waterways.
These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have
difficulties in disposing their garbage. The amount of garbage grows each year, but places to put it are
quickly filling up Citizens, governments, industries, scientists and business people must work
together in different ways to gradually reduce pollution.
True ( T ) or False ( F ) in the space provided
1/ Air pollution is a serious (dangerous) problem in many cities . __________
2/ Air pollution doesn't cause danger to people's health in some cities
3/ Motor vehicles and factories are some of sources of air pollution . ____________
4/ Only factories are the main source of air pollution ._________
5/ Air pollution is the only problem of the environment in this passage .
6/ Some areas are unfit for swimming because of the city wastes .____________
7/ The amount of the garbage in large cities reduces each year ._________
8/ Everyone must cooperate to reduce pollution . ______________
III/ Read the passage and answer the question :
Everyone wants to reduce pollution, but the pollution problem is as complicated as it is serious.
It is complicated because much pollution is caused by things that benefit people. For example,
exhaust from motorbikes causes large percentage of air pollution. But the automobile provides
transportation to millions of people. Factories discharge much of the material that pollutes air
and water, but factories give employment to a large number of people.
Thus, to end or reduce pollution immediately, people would have to stop using many things that
benefit them . Most people do not want to do that, of course. But pollution can be gradually
reduced in many ways. Scientists and engineers can work to find ways to lessen the amount of
pollution that such things as automobiles and factories cause. Governments can pass and enforce
laws that require businesses and individuals to stop or to cut down on certain polluting activities.
True ( T ) or False ( F ) :
1. All people want to reduce pollution_____
2. Pollution problem is neither complicated nor serious_____
3. Pollution is brought about by things that benefit people_____
4. People have to sacrifice what they have to stop or reduce pollution_____
5. The government can't do anything to stop or reduce pollution.______
IV/ Read the passage and answer the questions:
Every day on radio, on TV and in the newspapers, we hear , see, read about many problems in
the world , for example , pollution problems.
Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars,
airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped anywhere even
in the city where many people are living. The second pollution is sea pollution. Many people earn
their living from fishing the sea, and the fish they catch feed many people. But the sea has become so
polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the
fish, but also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more
difficult every day. We must find a good solution that makes the world a better place to live.
True — False — Not given?
1. Pollution is one of the city's problems_____
2. Exhaust fume comes from vehicles , airplane and factories_____
3. People pollute seas from dynamite fishing____
4. You can find easily a place nowadays that is not polluted_____

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.

rain, and to maintain the temperature of the planet. All are necessary for huma...

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

Experimental work is being done to derive Synthetic fuels from coal, oil shale and coal tars. Other experiments are underway to harness power with giant windmills. Geothermal power is also being tested.
Some experts expect 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.
