READING

I. Read the passage and complete the sentences. 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.

¨   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.

Because deaf people cannot hear, they have special ways of communicating. For example, they can learn to understand what someone is saying by looking at the mouth of the speaker. This is called lipreading. Also, speaking is very difficult for the deaf, because they cannot hear their own voices. However, it is possible with special training. According to many deaf people all around the world, the most practical and popular way of communicating is with sign language.

In many ways, sign language is similar to spoken language. The words of sign language are made with signs, which are formed with movements of the hands, face, and body. As with words, each sign has a different meaning and can be combined to form sentences. Sign languages also have their own grammar. The alphabet of sign language is special hand signs that stand for letters; they make spelling possible. The signs combine to form a rich language that can express the same thoughts, feelings, and ideas as any spoken language. And just as people from different countries speak different languages, most countries have their own variety of sign language.

Nowadays, big cities are facing with air pollution, one of the most serious global issues. One of the causes is vehicular traffic. The combustion of the automobile fuel whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. Smoke generated by factories is also let out into the air leading to pollution. Moreover, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke polluting the air. Air pollution always has bad effects on our life. People around the world are suffering from respiratory and cardiac problems, and diseases such as cancer affecting other organs of the body too.

Soil pollution has now become much more of a boiling issue to all countries in the world. Due to the appearance of many fertilizers and peside, farmers have been overusing them to contaminate the soil. This poses a great health threat as peole cultivate food on the land. Additionally, industrialization does not only lead to air pollution but also contribute greatly to the severeness of soil contamination. As more and more firms dump their untreated sewage right into rivers and the sea, the aqua environment become extremely hazardous for marine animals to survive. Moreover, the fresh water for daily activities will also be negatively affected. In order to improve the situation, several methods have been implemented by governments. However, I believe the most effective way to reduce soil pollution is raising people's awareness of the issue.
