The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere cannot think as quickly as other children and are clumsy when they use their hands. There are other long-term effects of pollution. If the gases in the atmosphere continue to increase, the earth’s climate may become warmer.

III. Read the following passage carefully and choose the best answer to each question. Identify your answer by writing the corresponding letter A, B, C or D on your answer sheet.

One of the most urgent environmental problems in the world today is the shortage of clean water. Having clean drinking water is basic human right. But 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. But they are being destroyed by the massive volumes of industrial effluent which pours into the lake everyday. Even where law existed, the government did 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.

1. According to the writer, one environmental problem in the world today is ________ .

A. acid rain B. industrial pollution. C. safe water shortage. D. population explosion .

2. Many sources of water are not drinkable because of _______ .

A. acid rain. B. industrial pollution. C. garbage D. all A, B, C, are correct

3. What is serious problem of Lake Baikal in Russia?

A. It contains a rich variety of animals and plants.

B. It is polluted by massive volumes of industrial wastes discharged into it .
