Exercise 1. Read the following passage and answer the questions
Everyday on radio, on TV, and in the newspaper, we hear, see or read about many problems in the world, for example, pollution problems.
Air pollution is the first kind. It mostly comes from fumes released from motorbikes, cars, airplanes, trains and poisonous gases emitted from factories. Also, waste is dumped any where, even in the city where many people are living. The second pollution problem is sea pollution. Many people earn their living from fishing in the sea, and the fish they catch feed many people. But the sea has become so polluted from oil spills and factory wastes that the fish are dying. This pollution is not only killing the fish, but is also affecting those people who eat fish.
Seldom do you find a place nowadays that is not polluted. This problem is growing more difficult everyday. We must find a good solution that makes the world a better place to live.

Exercise 2.
More than two hundred years ago, the term environment pollution was quite strange to people. They lived healthily, drank pure water and breathed fresh air. Nowadays, the situation is quite different. People all over the world are worried about things that are happening to the environment. Actually it is man that is destroying the surroundings with many kinds of wastes. Everybody knows that motorbikes and cars emit dangerous gases that cause poisonous air and cancer, but no one wants to travel on foot or by bicycle. Manufactures know that wastes from factories make water and soil polluted, but they do not want to spend a lot of their money on treating the waste safely. Scattering garbage is bad for our health, but no one wants to spend time burying it. Is it worth talking a lot about pollution?
