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：--請他不要吃太多的糖，糖對牙齒是有害的。--那是對的，但是他總是在吃后刷牙。這里是短語be good for sth對某物有好處。根據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數，故排除AB；根據常識可知糖對牙齒有危害，但是不能只對一顆牙齒有害，所以這里應該用名詞復數；第二空brush刷，brush one’s teeth刷牙。故選C。

考點：考查名詞及動詞的用法。
