had learned
had planted
had left
had been served
如果动作有前后顺序,发生在前的用“过去完成时”
发生在后的用 ”一般过去时”
E.g. She said that she had seen the film before.
2. 由”过去的过去”来判定
常用在宾语从句中
He said that he had given the book to the teacher.
We were surprised at what she had already done.
常用于主语从句中
It was said that the building had been destroyed.
常用于状语从句中

A Sichuan restaurant ___________________________(recommend) to us by a friend, and finally, we found it.
Tired, hungry, and not knowing a word of Chinese, we had no idea how to order, so the chef just began filling our table with the best food we _____________ ever (eat).
3. 由”语境(上下文)”来判定

wish
expect
think
intend
mean
suppose

It/This/That was the (first/second..) time+(that)+句子
句子用“过去完成时”
E.g.
It was the second time that I _________(lose) the chance.
This was the first time that he ___________(be)the winner.
2. 那是某人第几次做某事了。
试比较:

has visited
It/This/That was +形容词最高级+n+ that (+句子)
句子用“过去完成时”
E.g.

That was the most important finding that ____________(prove).
This was one of the useful bookes that I ______________(read).

had heard
had been proved
had read
试比较:

hardly(scarcely/barely)..(had done)..when..(从句用did)
no sooner..(had done)..than...(从句用did)
注:
主句用”had done”,从句用“did”
主句翻译为“一...”,从句翻译为“就...”
若hardly/scarcely/barely/no sooner(否定词) 位于句首,则主句部分, 用部分倒装,即: had+主语+done…
4. 一...就
5. 刚刚做完...,此时...
...had (just) done sth. when...
E.g.
He had (just) turned off the computer when his mom went back.
