Question

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．a(chǎn)ll of them
C．none of whom	D．a(chǎn)ll of whom

Answer 1

C

試題分析：句意：我們有最支持我們的父母和老師，如果我們不努力，誰對(duì)我們的學(xué)習(xí)也沒有多大的作用。逗號(hào)前后都是句子，這里缺少連詞，故排除AB；這是定語從句，先行詞是parents and teachers，從句缺少的是主語，none of whom他們中沒有；all of whom他們所有的人，根據(jù)句意故選C。
