X. Read the passage carefully and do the tasks.
There are many kinds of pollution. Air, water, and land can be polluted. Some pollution is caused by
nature, such as foods, forest fires, and volcanoes. People are the major Cause of pollution. We pollute the
air with our cars, homes, and factories. Smoke from factories and car exhaust makes the air looks gray and
smoggy. Some people cannot go outside when the air is very bad! We pollute the water by dumping
garbage and Chemicals in the water. Plants and animals die because of the pollution in the water. We
pollute the soil with Chemicals and garbage. We harm the land by cutting down trees in the forest,
especially to build roads and new houses without careful planning and thinking.
The only way to save our environment is to think about pollution. How can you stop or limit pollution?
How do we protect our environment? Conservation is one way to protect our environment. Conservation is
the wise use and protection of our environment. We can control water pollution by not producing as much
as waste and by proper disposal of sewage and garbage. We can take care of recreation land by cleaning up,
after ourselves and not causing more pollution. Carpooling and public transportation will help reduce air
pollution.
Recycling is a type of conservation. Recycling is reusing items over again or in a new way. Recycling can
help us conserve our natural resources so they will last many more years. A. Find the word in bold in the

II. Read the following passage and choose the correct answer.
The search for alternative sources of energy has led in various directions. Many
communities are burning garbage and other biological waste products to produce
electricity. Converting waste products to gases or oil is also an efficient way to dispose of
waste.
Experimental work is being done to derive synthetic fuels from coal, oil shale and coal tars.
But to date, that process has proven expensive. Other experiments are underway to
harness - power with giant windmills. Geothermal power, heat from the earth, is also being
tested.
Some experts expect utility 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.
