答案与提示:

1.B

  根据句意和定冠词the来判断important要用最高级。

2.B

  eat和drink是一个搭配。

3.A

  根据but一词可确定前面的句子应是一个否定句,所以答案C、D不能用。英语中有though就不能用but,所以答案B也不对。只有答案A是对的,意思是:很少有人知道这个道理,但它的确是个事实。

4.A

5.A

6.D

7.D

  句意是:人们没有食物可以活很长一段时间,然而没有水两、三天通常就能使人死去。这里food和water是一对对比词。

8.B

  在英语中water是个不可数名词,要用how much来修饰。

9.C

  这句中的need是个实义动词,后接一个不定式。

10.A

  根据句意是:即使是在热天许多人也没有喝足够的水。

11.C

  根据常识填。

12.B

  这句不仅根据句意,而且还要注意到这个复合句的主句是将来时,从句是一般现在时,所以在四个选项中只有用if引导的条件状语从句符合这条规则。

13.B

  enough修饰名词时可以放在名词前,也可以放在名词后。

14.D

  这句意思是“所以你知道……”。

15.C

  water是不可数名词,所以动词用单数。
