II. Read carefully the passage:
       Every day in radio, on TV, and in the newspapers, 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 dump anywhere, 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.
