Read the following passage and answer the questions.
The natural world is under violent assault from man. The seas and rivers are being poisoned by
radioactive wastes, by chemical discharges and by the dumping of dangerous toxins and raw sewage. The air
we breathe is polluted by smoke and fumes from factories and motor vehicles; even the rain is poisoned.
Its little wonder forests and lakes are being destroyed and everywhere wildlife is disappearing. Yet the
destruction continues. Governments and industries throughout the world are intensifying their efforts to
extract the earth's mineral riches and to plunder its living resources. The great rainforests and the frozen
continents alike are seriously threatened despite the warnings of the scientific community and the deep
concern of millions of ordinary people.

Despite the fact, too, that we can create environmentally clean industries, harness the power of the sun,
wind and waves for our energy needs and manage the finite resources of the Earth in a way that will
safeguard our future and protect all the rich variety of life forms which share this planet with us.
But there is still hope. The forces of destruction are being challenged across the globe - and at the
spearhead of this challenge is Greenpeace. Wherever the environment is in danger, Greenpeace has made a
stand. Its scientific presentations and peaceful direct actions at sea and on land have shocked governments
and industries into awareness that Greenpeace will not allow the natural world to be destroyed. Those
actions, too, have won the admiration and support of millions.
Now you can strengthen the thin green line; you can make your voice heard in defense of the living
world by joining Greenpeace today. Thank God someone's making waves.

Read the following passage and answer the questions.
Since the world became industrialized, the number of animal species that have either become extinct or
have neared extinction has increased. Bengal tigers, for instance, which 'once roamed the jungles in vast
numbers, now number only about 2,300. By the year 2025, it is estimated that they will become extinct.
What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost
entirely by poachers who, according to some sources, are not always interested in material gain but in
personal gratification. This is an example of the callousness that is contributing to the problem of extinction.
Animals such as the Bengal tiger, as well as other endangered species, are valuable parts of the world's
ecosystem. International laws protecting these animals must be enacted to ensure their survival - and the
survival of our planet.
Countries around the world have begun to deal with the problem in various ways. Some countries, in an
effort to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge
admission prices to help defray the costs of maintaining the parks, and they often must also depend on world
organizations for support. This money enables them to invest in equipment and patrols to protect the


animals. Another response to the increase in animal extinction is an international boycott of products made
from endangered species. This has' had some effect, but by itself It will not prevent animals from being
hunted and killed.

Read the following passage and answer the questions.
Scientists believe they now have scientific evidence to prove that ecosystems work better when there is
greater variety of species within them. This biodiversity is being destroyed by lost natural mechanisms that
could repair the damage caused by man.
Findings show that losing plants and animals is not only reducing our quality of life but actually
endangering our very existence. We cut down rich rainforests and replace them with one species plantations,
such as pine and eucalyptus. We plough up meadows rich in different grasses and herbs and replace them
with one grass, for instance rye or wheat.


When a natural ecosystem is simplified the basic processes in the ecosystem are altered and even

damaged. Without their biodiversity they are not able to serve as the natural cleaners of our planet. No
longer are they able to absorb the carbon dioxide that is being produced in excess. The result is global
warming, caused by the increase in the greenhouse effect, and ultimately, or even sooner, there will be a
change in the world's climate.
1. Which of the following is the best title for the passage?
a. How Ecosystems Work Better
b. The Loss of Biodiversity
c. The Variety of Species
d. Natural Mechanisms
2. Which of the following is not a species used to replace a rich ecosystem?

3. What is the purpose of paragraph 2?
a. To show natural mechanisms at work.
b. To give examples of the loss of biodiversity.
c. To give example of variety of species.
d. To show how ecosystems can work better.
4. What, according to the passage, might be the final result of the simplification of natural ecosystems?
a. The basic processes are altered
b. There is loss of biodiversity
c. There is global warming
d. There is a change in the climate.
5. What is the author’s attitude to the loss of biodiversity?
a. Indifferent b. Negative c. Positive d. Neutral

Although they are safe to use in the short term, coal, gas and oil present a long-term (1) ...... to the

Read the following passage and answer the questions.
At present, people depend on unlimited energy to power their everyday lives. A wide range of energy-run
devices and modern conveniences are taken for granted, and although it may seem that we will never be in
danger of living without those conveniences, the fact is that many supplies of energy are dwindling rapidly.
Scientists are constantly searching for new sources of power to keep modern society running. Whether
future populations will continue to enjoy the benefit of abundant energy will depend on the success of this
search.
Coal, oil, and natural gas supply modern civilization with most of its power. However, not only are
supplies of these fuels limited, but they are a major source of pollution. If the energy demands of the future

are to be met without seriously harming the environment, existing alternative energy sources must be
improved or further explored and developed. These include nuclear, water, solar, wind, and geothermal
power, as well as energy from new, nonpolluting types of fuels. 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 pose the daunting problem of what to do with
nuclear wastes. Hydroelectric power is inexpensive and environmentally safe, but impractical for
communities located far from moving water. Harnessing energy from tides and waves has similar
drawbacks. Solar power holds great promise for the future but methods of collecting and –concentrating
sunlight are as yet inefficient, as are methods of harnessing wind power.
Every source of energy has its disadvantages. One way to minimize them is to use less energy.
Conservation efforts coupled with renewable energy resources, such as a combination of solar, water, wind,


and geothermal energy and alternative fuels, such as alcohol and hydrogen, will ensure supplies of clean,
affordable energy for humanity's future.
1. The passage suggests that ______.
a. people use energy without giving great thought to 'where it's coming from.
b. the search for energy sources is mainly a problem for the future
c. scientists believe we will never have to go without our modern conveniences
d. modern society requires a minimum amount of energy to keep running
2. It can be implied from the passage that ______.
a. most alternative energy sources have proven to be impractical
b. many alternative energy' sources. are environmentally hazardous
c. nuclear power solves one problem while creating others
d. solar and wind power are not promising for the future
3. From the passage, it can be inferred that to solve our energy problems ______.
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

d. a combination of conservation and invention will be needed
4. Which of the following can be inferred from the passage?
a. The search for alternative energy sources is not over.
b. Our present energy sources must be eliminated and replaced with alternatives sources.
c. Alternative sources of energy on this planet are very limited.
d. Demand; for energy in the future are likely to decrease.
5. Which of the following is not true according to the passage?
a. The amount of fossil fuels in the world is limited.
b. Most alternative energy sources are environmentally friendly.
c. Hydroelectric power is impractical because of its being money consuming.
d. It is impossible to use wind power efficiently at present.
