九年级英语培优练习（十三）

A

Waste paper and used coke cans are thrown out anywhere and everywhere. You might have seen plastic bags flying in the sky when the wind blows and getting caught in the trees. Or maybe you’ve seen old cans sitting in the rivers and polluting the water.

Our environment, the place we live in, is being ruined by us.

Believe it or not, every family in China makes about one ton of rubbish every year. That’s over 100 million tons of rubbish in China alone. It is enough to fill a line of 10-ton trucks that goes around the world almost five times. All this rubbish makes our soil, our water and our air dirty. And so it affects our health. Bad habits, such as dropping litter, add to this problem. Many people think that dropping one small piece of chewing gum doesn’t matter too much.

But, did you know that nearly 6000,000 pieces of gum were stuck to Tian’anmen Square during the last National Day holiday? It cost 0.2 yuan to remove each piece. And it will take many years for the stains of gum to disappear.

So it is clear that we can not go on living like this. We need to cut down on our waste. This world is ours. It is our only world. And it is the job of every person to make an effort to save it.
