I/read the passage and answer the following question:
Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater (the water beneath the Earth’s surface). It is one of the most serious types of pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Sewage from households is another cause. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to water pollution. These factors cause ‘point source’ pollution while pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
Water pollution can have dramatic effects.
1.what are point source pollutants?
=> Factories dump industrial waste into lakes and rivers, sewage from households, farms using pesticides to kill insects and herbicides to kill weeds are point source pollutants.
2.what are the non-point source pollution
=> Pollutants from storm water and the atmosphere result are non-point source pollution.

Air, which is the most important element of our environment for our (2) …survival, can be polluted in many ways. Smoke in the air from mills, factories and industry (3) …contains… carbon, monoxide, carbon dioxide, and methane, which are all poisonous gases. This leads (4) …for… health problems like asthma and lung diseases, and the thinning of the ozone layer, which (5) protects… us from harmful UV ray. China, the USA, Russia, India, Mexico and Japan are the world leaders in air pollution (6) …emissions… Water is also polluted by the discharge of commercial and industrial waste. Sewage in drinking water is another (7) …cause … of water pollution as it contains germs and viruses. The noise of vehicles, mills, and factories can be really unbearable. This kind of constant sound also (8) …causes… headaches, tension, (9) …mental… stress and migraines. People living next to a building site where there is too much noise can become sick, as they can not sleep or relax. This is (10) called… noise pollution.
Water pollution is a major global problem which requires ongoing evaluation and
revision of water resource policy at all levels. It has been suggested that water
pollution is the leading worldwide cause of deaths and diseases, and that it accounts
for the deaths of more than 14,000 people daily. An estimated 580 people in India
die of water pollution related illness every day. About 90 percent of the water in the
cities of China is polluted. As of 2007, half a billion Chinese had no access to safe
drinking water. In addition to the acute problems of water pollution in developing
countries, developed countries also continue to struggle with pollution problems. For
example, in the most recent national report on water quality in the United States, 44
percent of assessed stream miles, 64 percent of assessed lake acres, and 30
percent of assessed bays and estuarine square miles were classified as polluted.
The head of China’s national development agency said in 2007 that one quarter the
length of China’s seven main rivers were so poisoned the water harmed the skin.
Water is typically referred to as polluted when it is impaired by anthropogenic
contaminants and either does not support a human use, such as drinking water, or
undergoes a marked shift in its ability to support its constituent biotic communities,
such as fish. Natural phenomena such as volcanoes, algae blooms, storms, and
earthquakes also cause major changes in water quality and the ecological status of
water.
1. What is the leading worldwide cause of deaths and diseases?
Water pollution is the leading worldwide cause of deaths and diseases.
2. How many people die every day by water pollution?
More than 14,000 people die every day by water pollution.
3. How many percent of the water in the cities of China is polluted?
25% of the water in the cities of China is polluted.
5. What phenomena cause major changes in water quality and the ecological status
of water?
Volcanoes, algae blooms, storms, and earthquakes.

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.
