我國最大的壞境問題便是空氣污染和水資源污染嚴重，導致各種疾病發(fā)病率怎家。環(huán)境問題是一個全球性問題，世界攜手對地球負責，才能共同解決。保護地球這個我們賴以生存的家園，人人有責。

bruce:

I think the biggest environment problem in my country is air pollution.

我覺得我們國家最大的環(huán)境問題是空氣污染。

lily:

Yes, I agree. The air here is much more polluted than in my country. Of course, my country is more agricultural and has much less industry.

我同意。這里的空氣污染比我們國家嚴重多了。當然，我們國家農業(yè)比重比較大.工業(yè)比重比較小。

bruce:

We have reduced emission of air pollutants in recent years, but cars are still a major source of them. Factories have become cleaner as stricter environment pollution law have been introduced.

我們這些年也在減少有害氣體排放量，但是汽車廢氣排放依然是空氣污染的主要原因.隨著環(huán)境保護法的頒布。工業(yè)廢氣排放沒有以前嚴重了。

lily:

The problem is now on a truly global scale. I don`t believe that any single country can do anything about it.

問題是現在的問題是個全球性問題。我不認為單憑一個國家的力量就能解決問題。

bruce:

I think you`re right. There needs to be an international response to this problem.??

你說得對。環(huán)境問題需要全世界的國家負起責任來共同合作解決。
