Question

Last Sunday my father and I went fishing along a river. We found the water very dirty that we could hardly catch any fish in it. A lot of factories along the river always poured their waste water and rubbish straightly into the river, which made the river polluting. In this way most of the fish in the river was killed. Unless the rivers all over the country are polluted like this, no living things will be exist in the water. As we all know, environmental pollution do great harm to living things. Now more and more people have realized what serious this problem is. Our government is doing her best to take measure to fight against pollution. We expect that water in every river will be made cleaner and cleaner before long.

Answer

1.第二句的very→so

2.第三句的straightly→straight

3.第三句的polluting→polluted

4.第四句的was→were

5.第五句的Unless→If,

6.第五句的be去掉

7.第六句的do→does,

8.第七句的what→how,

9.第八句的measure→measures,

10.第九句在that后加the,

【解析】

1.第二句的very→so, 构成“so. . . that. . . ”结构, 表示“如此……以至于……”。

2.2】第三句的straightly→straight, straight既可用作形容词, 也可用作副词。而straightly这个副词在现代英语中已被废弃, 许多词典均不再收录此词。

3.3】第三句的polluting→polluted, 因为river与pollute之间是被动关系, 所以用过去分词作宾语补足语。

4.4】第四句的was→were, 因为most of the fish in the river表示“河里的绝大多数鱼”, 而fish表示“鱼”时, 是可数名词。

5.5】第五句的Unless→If, 此处表示“如果全国的河流都这样被污染, 水里就不会有生物存在”。

6.6】第五句的be去掉, exist表示“存在”, 是不及物动词。

7.7】第六句的do→does, 主语pollution是不可数名词, 谓语动词应该用单数。

8.8】第七句的what→how, how修饰形容词serious, 表示“……是多么严重啊”。

9.9】第八句的measure→measures, take measures是固定短语, 表示“采取措施”。

10.0】第九句在that后加the, 特指河里的水。
