为什么不选A,不是强调句是特殊疑问词加十IS十it 十that

问题描述:

为什么不选A,不是强调句是特殊疑问词加十IS十it 十that
What did the teacher want to know most
-_______I could finish writing the report.
A.When was it
B.When it was that

这个句子省略了部分结构
完整的结构是 :(The teacher wated to know that )When it was that
I could finish writing the report.
这里省略了主句,只说了从句,从句当然是陈述语序.
另外你也看见了,句末是句号而不是问号啊~
