问题 选择题

We do have the most supportive parents and teachers, ________will make a difference to our study, unless all of us make every effort .

A.none of them

B.all of them

C.none of whom

D.all of whom

答案

答案:C

题目分析:句意:我们有最支持我们的父母和老师,如果我们不努力,谁对我们的学习也没有多大的作用。逗号前后都是句子,这里缺少连词,故排除AB;这是定语从句,先行词是parents and teachers,从句缺少的是主语,none of whom他们中没有;all of whom他们所有的人,根据句意故选C。
