VII - Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but shouldalso try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.

If we do our part in our own homes, we can help keep the planet from becoming more polluted.

44, The average person produces every day _______.

A. three point four pounds of waste B. thirty four pounds of waste

C. four point three pounds of waste D. forty three pounds of waste

45, If we do our part in our own homes, we can help keep ______.

A. the planet from becoming less polluted B. the planet from becoming more polluted

C. the house from becoming few polluted D. the planet from becoming little polluted

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_____

In this section you will find after the passage a number of questions about the passage. You must choose the one which you think fits best . Write your answers in the spaces below (1.0pt)

Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing material more than 5000 years ago. The Chinese invented the paper that we use 2000 years ago.

A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resin may add weight and texture.

Where do these fibers come from ? The majority of paper is made from the plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may be also made from things like old rags or pieces of cloth. Wastepaper, paper that has been made and used, can be turned into recycled paper. This recycling process saves forest, energy and reduces air and water pollution.

1. According to the passage, the paper that we use was first invented by

A. the Chinese B. the Egyptians C. ancient cultures D. foresters

2. What is the main ingredient in most paper ?

A. resin B. cardboard C. plant fiber D. papyrus

3. According to the passage, the primary source of the plant fiber used in paper is

A. rags B. trees C. fabric D. wastepaper

4. According to the passage, recycling paper is

A. bad for the environment C. good for the environment

B. wasteful D. economical

5. According to the passage, recycling paper does all of the following EXCEPT

A. reduce the need for ink C. save energy

B. save forests D. reduce air pollution
