Question

【题目】—All the volunteers were very tired, but　 of them took a rest.

—They were busy looking for the missing people.

A. neither B. all C. both D. none

Answer 1

【答案】D

【解析】试题分析：句意：-所有的志愿者都很累了，但是他们中没有一个人休息。-他们正忙着寻找失踪的人。neither 两者都不；B. all 三者或三者以上都；C. both 两者都；D. none 三者或三者以上都不。因为前面说到志愿者时用的是All，所以志愿者应该为三者或三者以上，相对应的，选D。
