题目内容
1.-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 |
分析 --所有的志愿者都非常累,但他们中没有一个人休息.
--他们正忙着寻找失踪的人.
解答 答案D.本题考查不定代词的用法.不定代词的定义是:不指明代替任何特定名词或形容词的代词叫做不定代词.all 与 both均表示"都",但 all 表示三者以上的人或物,both 则表示两个人或物.二者都表示肯定意义.neither 表否定意义,意为"(两者中的每一个)都不",none既可指人,也可指物,强调数量,意为"一点也不,一个也不",常与 of 连用,通常指"三者以上的人或物中没有一个".本题的主语是All the volunteers,表明是三者以上,即所有的志愿者都很累,连词but表转折,所以应该用表示否定的none,故本题选D.
点评 了解每一个不定代词的意思和用法才能正确答题.
