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】

試題分析：句意：--請(qǐng)他不要吃太多的糖，糖對(duì)牙齒是有害的。--那是對(duì)的，但是他總是在吃后刷牙。這里是短語be good for sth對(duì)某物有好處。根據(jù)them after eating可知用them代替上文空格處的名詞，所以這里的名詞必須是復(fù)數(shù)，故排除AB；根據(jù)常識(shí)可知糖對(duì)牙齒有危害，但是不能只對(duì)一顆牙齒有害，所以這里應(yīng)該用名詞復(fù)數(shù)；第二空brush刷，brush one’s teeth刷牙。故選C。

考點(diǎn)：考查名詞及動(dòng)詞的用法。
