from

such

when

pollution

health

Dwellers who live in urban areas in developing countries have to co-exist with many environmenta issues
frequently. Typically, they are forced to get acquainted with noise (1)_________________________that stems
from heavy traffic flow, industrial buildings as well as annoying sounds of daily activities in the neighbourhood.
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.

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.
5. Everyone must cooperate to reduce pollution.
Exercise 3. Read the text carefully then answer the following questions.
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.

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________________.
