面包机怎么做面包视频:before与that

B
========
意思是在我们又一次见到之前已经过了两年。
it was 可以换成 it had been ，是同样的意思。
===========
如果是that。则是强调句。it was .... that ....
可以换成 We met again two years .显然是不通的。
所以如果要用that .
应该说It was two years ago that we met again.

before
before 一个很特殊的意思
才

两年后我们才再次见面。

that

我觉得是个强调句型.it was ......that

b,
如果是A的话那就是IT WAS THAT 的强调句了，调整一下就是we met again two years，缺个介词，所以选B，

Iy was 2 years before we mey again.表示时间的状语，在..之前后面接从句we met again

before

before
