Read the following passage and choose the best answer:

One of the most urgent environmental problems in the world today is the shortage of clean water.Having clean drinking water is a basic human right. However, acid rain, industrial pollution and garbage have made many sources of water undrinkable. Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1, 300 rare species that do not exist anywhere else in the world. Yet, they are being destroyed by the massive volumes of industrial effluent which pour into the lake every day. Even though laws have been made, the government do not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world's water surface, but it is the dumping ground for 50% of all marine pollution. Almost 16 countries regularly throw industrial wastes a few miles off shore.        Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect this precious source. We should do something now.

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_____

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is a basic human right. However, acid rain, industrial pollution and garbage have made many sources of water undrinkable. 

Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world.

Almost sixteen countries regularly throw industrial wastes a few miles offshore.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is a basic human right. However, acid rain, industrial pollution and garbage have made many sources of water undrinkable. 

Lakes, reservoirs and even entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largest lakes in the world. It contains a rich variety of animals and plants, including 1,300 rare species that do not exist anywhere else in the world. Yet, they are being destroyed by the massive volumes of industrial effluent which pour into the lake every day. Even though laws have been made, the governments do not have the power to enforce them. Most industries simply ignore the regulations. The Mediterranean Sea occupies 1% of the world's water surface, but it is the dumping ground for 50% of all marine pollution. Almost sixteen countries regularly throw industrial wastes a few miles offshore. 

Water is free to everyone. A few years ago people thought that the supply of clean water in the world was limitless. Today, many water supplies have been ruined by pollution and sewage. Clean water is now scarce, and we are at last beginning to respect it. What should we do to save this precious source?

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.
