Question

I can't remember how many days ago --- a fight broke out between them.

A it was when B it was that C was it when D was it that
选B 请解释为啥不能选A

Answer 1

这句不是强调句。而是宾语从句套主语从句。
因为how many days ago 以及之后的部分是remember的宾语从句。宾语从句应该是陈述句的形式，所以排除C，D
而宾语从句中，a fight broke out between them 是主语从句 ，引导词应该用that，不用when。it 做了a fight broke out between them的形式主语
还原成正常的语序应该是 it was (how many days ago) that a fight broke out between them。

Answer 2

首先这是一个强调句做remeber的宾语的句式。下面我们把它单独抽离出来：
--------------------how many days ago____a fight broke out between them.从选项我们就可以看出出题者的意图是考察强调句的句式。我们先将它还原看是否符合强调句的要求。
It was {how many days ago} (when/that) a fight broke out between them.
It was+被强调部分 +that/who(m) +其他成分
这样的话我们先选定that，排除when。这样就剩B，D。而他们之间只是语序问题，既然是强调句做了宾语。当然选用陈述语序了。明白了吗，判定是不是强调句还有一个方法就是把It be和that/who(m)去掉，看句子是否完整。看着两个句子：
It was 7 ————I got up this morning.
It was at 7_____i got up this morning.
看看填什么，我们继续交流，呵呵
