题目内容
It isn’t clear_____ is to blame.We need to find a solution to the problem first.
A.who is it that | B.who it is that | C.it is who that | D.that who it is |
B
解析试题分析:这里It是形式主语,who引导的是真正的主语从句,从句是强调句型,被强调部分是who,因为who是连词必须放在主语从句的句首,又因为主语从句的语序是陈述语气。故选B。温馨提醒:强调句型的结构:it be 被强调部分+ that+其他,判断强调句型的方法是把it be that去掉,整个句子是成立的。
考点:考查主语从句的语序及强调句型的用法
点评:把主语从句与强调句型放在一起考查,增加了试题的难度,考生必须这两个知识点都能熟练掌握才行,近几年高考单选考查多个知识点的频率高了。
