Dwellers who live in urban areas in developing countries have to co-exist with many environmental issues frequently.

This can lead to serious hearing loss and negative effects on people’s mental (2) ____________. In addition, the poor sewage system and littering are the two major contributors to directly spoiling the citizens' quality of life and urban landscapes. In the rainy season, it might be a disaster (3) ____________ city streets are full of rubbish and water waste after pouring rain. Besides, smoke and exhaust fumes released (4) ____________ dozens of vehicles and factories result in air pollution in crowded residential areas. Furthermore, big cities are associated with the origin of new types of pollution (5) ____________ as light pollution and visual pollution, banning residents’ fitness and well-being.
Exercise 2. Read the passage, then tick True (T) or False (F).
Air pollution is a serious problem in many cities. Motor vehicles, factories and other sources 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 of 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. For example, most cities have introduced recycling programmes.
Exercise 3. Read the text carefully then answer the following 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 control the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher orwashing 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 should also 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.
1. Pollution is caused from the following sources except ____________.
A. water in rivers B. water from households
C. wastes D. house chemicals
2. Recycling can help us ____________.
A. never cut down trees B. produce more paper products
C. place garbage bins easily D. use products again and again
3. In order to save water, we can do all of the following things except ____________.
A. fully use the washing machine
B. repair leaky faucets
C. take short showers instead of baths
D. turn the faucet off while brushing your teeth
4. Recycling helps to reduce waste because ____________.
A. plants need to develop
B. waste can be recycled and reused
C. a person can do it in his home
D. an average man produces compost for plants
5. The word “It” in paragraph 2 refers to ____________.
A. cutting down B. the number C. recycling D. effort

III. READING
Exercise 1. Read and fill in the blanks with the words given.
from | such | when | pollution | health |
Exercise 2. Read the passage, then tick True (T) or False (F).
Air pollution is a serious problem in many cities. Motor vehicles, factories and other sources 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 of 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. For example, most cities have introduced recycling programmes.
Statements | T | F |
| 1. Motor vehicles and factories are among some sources of air pollution. | ||
| 2. Air pollution doesn’t endanger people’s health in some cities. | ||
| 3. Air pollution is the only problem of the environment mentioned in this passage. | ||
| 4. Garbage disposal is a problem in many large cities. | ||

Saving the Environment: One Home at a Time
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 control the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher orwashing 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 should also 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.
