题目内容
Tigers eat fruits and the camel eat meat .
- A.don’t ; doesn’t
- B.doesn’t ; don’t
- C.don’t ; don’t
- D.doesn’t ; doesn’t
试题分析:在一般现在时态中,当句子中有行为动词时,应该用结构:当句子的主语为非三单形式时,要借助于助动词do,其结构为:主语+don’t 动词原形+其他;主语是三单时,其结构是主语+doesn’t+动词原形。当句子中没有行为动词时,要在be 动词后面加not。根据选择项的提示可知eat是行为动词,且主语是tigers和the camel前者要用don’t,后者要用doesn’t,故选A。
考点:本题考查的是一般现在时态的否定句的构成
点评 :学生要注意一般现在时句子中行为动词的否定句的构成,尤其特别是当主语为三单形式时谓语动词的否定句结构,谓语动词要用原形。

A.don’t ; doesn’t | B.doesn’t ; don’t |
