it is......when.....it is....that的区别

A. it was that
B. ia was when
学生们都喜欢选择B 答案

Answer 1

答案应该是A吧! 强调句型啊!
这题只能选A但在看定语从句还是状语从句时that与when 很容易误选.如:
I don't remember the days when we stayed together in Beijing.
when 后面句子成分完整了用when句子是状语从句
再看,
I don't remember the days that we apent together in Beijing.
that后面spent缺少宾语所以用that该句是定语从句.

Answer 2

how many years ago 是指多少年前,在这里不做时间状语所以不能用when ,提问哪一年才用when 来引导

Answer 3

是强调句？

Answer 4

B
