Question

1. I can’t remember

1. I can’t remember _____________ made the teacher give Mary the permission to leave the class earlier.
A. that it was what B. what it was that C. what was it that D. that was it what 为什么

Answer 1

选B。
I cant remember what it was，这里不要用what was it，what was it是用疑问句的，陈述语气要用回what it was。后面的that引导的定语成分是用来修饰what这个东东。
整句的意思是 我记不起是什么让老师批准玛丽提早离开教室。

Answer 2

选B首先后面的句子缺少主语要用what，然后it was that 强调句，强调后面句子的主语what
