BÀI TẬP BỔ TRỢ VÀ NÂNG CAO - UNIT 5 I. Read the following text then answer the questions below Pollution: How to reduce it The world that we live in now is badly affected by pollution. The rivers and seas are polluted. The air is polluted. The land is polluted. Consequently the things we drink, breathe and eat are all polluted. This sad state of affairs are not good for our health and well-being. Pollution is virtually destroying the place we live in Earth. If pollution is allowed to go on and on we will surely destroy ourselves too. We ought to value our planet for it is the only place we can live in it. If we destroy it then we are also finished. Eliminating pollution completely is impossible. So it is important that we try to keep pollution to a minimum. There are many things that we can do to reduce it. The first thing for everyone is to stop dumping rubbish anywhere they like. We can see piles of rubbish on road sides, in ditches and drains, in back lanes and often on main roads too. Perhaps we could recycle the things we use instead of simply throwing them away. We could, for example, reuse glass, metals and plastics. We could keep our cars and sinks in good working order instead of abusing them as many of us can do now. Then we would have less rubbish t o throw. Consequently there would be less rubbish dumps and less pollution. Motor vehicles are major cause of air pollution. They emit much exhaust fumes. In big cities this pollution has reached levels that pose a threat to the health of the city dwellers. Some cities have already advised their residents to wear gas masks when they venture onto the streets. The only way to reduce this pollution is obviously to reduce the number of vehicles on the roads. This is easier said than done for very few people wou ld want to sacrifice the convenience of having one’s own transport. Factories and industrial plants are largely responsible for pollution of the air, water and land. The waste they discharge into the rivers and land destroy both. The smoke they emit pollutes the air. What they must do is to find ways to reduce their wastes. Also they have to treat their wastes so that they are harmful. All these things are required if we are
to see any reduction of pollution. At the rate things are going; however, we see increase in pollution instead. Whether we can really reduce pollution and thus save our planet is up to us. Pollute it more and we shall perish. 1. How many ways of reducing pollution in this text? 2. By what way can we reduce pollution? 3.
