It is very important to deal with the rubbish in cities. For one thing, rubbish may cause a lot of pollution. It may pollute the air, the water and the places we live in. For another, it may do harm to people's health.

　　So in our city, rubbish is well dealt with. First, it is sorted. Then old newspapers and glass are recycled. The harmful wastes are buried and the waste water is cleaned before it goes into the river. The government has already made laws against pollution caused by rubbish.

　　But that's not enough. We must all try our. best to prevent rubbish from polluting the environment so as to. save our city and our living place.

　　拯救地球

　　處理城市垃圾是一個非常重要的問題。首先，垃圾會導(dǎo)致污染。它會污染空氣、水和人們居住的場所。其次，它會危害人類健康。

　　所以我們在城市中，垃圾得到了妥善處理。我們首先將垃圾分類，然后可將舊報紙和玻璃制品進行再生利用。有害的廢物要被掩埋，污水要在凈化后才排入河流。政府已經(jīng)制定了規(guī)章，禁止垃圾污染。

　　僅僅這些還不夠。我們大家必須竭盡全力防止拉圾污染環(huán)境以及拯救我們的城市，拯救我們的家園。
