It is important to deal with the rubbish in cities. Rubbish must be treated properly. Otherwise it may cause a lot of problems. It may pollute the air and water. When people breathe the polluted air or drink the polluted water, they may get iii.
　　Our city has begun to pay attention to the problem. As far as I know, some rubbish is sorted and sent to different factories. Rubbish,such as old newspapers and glass, is recycled.
　　Some harmful rubbish is sent to a certain place and buried.Waste air is cleaned before it goes into the air. Waste water is treated before it is poured into rivers。
　　To protect the environment, the government has passed laws to prevent people from throwing rubbish everywhere. We should do our best to take good care of the environment and fight against pollution.
　　處理城市垃圾非常重要。垃圾必須被合理地處理,否則,它會帶來很多問題,它可能會污染空氣和水。當人們呼吸這些被污染了的空氣、飲用這些污水時,他們或許會染上疾病。
　　我們的城市已經(jīng)開始注意到這個問題了。據(jù)我所知,一些垃圾已被分類,然后被送到不同的工廠。像舊報紙、玻璃等可以被重新利用。
　　一些有害的垃圾可以被送到某一個地方埋掉。廢氣在被利用之前可以被凈化,廢水可以在流入江河之前被處理。
　　為了保護我們的環(huán)境,政府已經(jīng)通過了法律來阻止人們亂扔垃圾。我們應(yīng)當盡力好好地保護我們的環(huán)境,與污染作斗爭。
