Question

--- Ask him not to eat too much candy, it’s not good for his ________.

--- That’s right, but he always ________ them after eating.

A. tooth, washes

B. health, showers

C. teeth, brushes

 

Answer 1

C

【解析】

试题分析：句意：--请他不要吃太多的糖，糖对牙齿是有害的。--那是对的，但是他总是在吃后刷牙。这里是短语be good for sth对某物有好处。根据them after eating可知用them代替上文空格处的名词，所以这里的名词必须是复数，故排除AB；根据常识可知糖对牙齿有危害，但是不能只对一颗牙齿有害，所以这里应该用名词复数；第二空brush刷，brush one’s teeth刷牙。故选C。

考点：考查名词及动词的用法。
