Answer 1

1. 把do改为deal。do with表示“处理”只能用于与what连用的疑问句中，否则，它是“需要、想要、忍受”之意(常与can, could连用)。

2. 把thus改为otherwise。前后不是因果关系，而是“否则”“如果不处理好的话，就会…”。

3. 在drink后加the。the polluted air与the polluted air是并列关系，特指前句提到的那些被污染了的空气和水。

4. 把we改为they。因为替代的是前面的people。

5. 把factory改为factories。不同的工厂，当然不只一家。

6. 把are改为is。因为主语是rubbish，是单数，当然用is。

7. 把after改为before。由前后意义的逻辑关系所知。

8. 在poured前面加is。因为it(waste water)与pour(倒)是被动关系。

9. 去掉protect后面的from。protect本身是及物动词，protect…from…意为“保护…免受…”。

10. 此行正确。
