it was 3 years before i had graduated from the university 对吗?
也就是it is 过去式 before 过去完成时

如果想说“我大学毕业后已经过了三年”,不能用 before,应该改为 since,即：

it was 3 years (since) I had graduated from the university.

　　it 是指代时间的非人称代词,意思是直译是‘自从我大学毕业以来,时间已经过了三年’.

如果用 before,可以说——

it had been 3 years before I graduated from the university,

　　但是意思成了“三年过去了,我才大学毕业（直译是‘在我大学毕业以前,时间已经过了三面’）”.

用 since,过去的“毕业时间” 早于 “三年过去”；用 before,“三年过去” 早于过去的“毕业时间”.

关于 since 的用法

1、如果主句说明的是现在的情况,主句用现在完成时态,从句用一般过去时态.如：

We have both changed since we parted. （从那时）分别以来我们（现在）彼此都变了.

2、如果主句说明的是过去的情况,主句用一般过去时态,从句用过去完成时态.如：

We both changed since we had parted. （从过去的过去）分别以来我们（那时）彼此都变了.

3、如果主句是表示时间的“ it + 系动词”结构,说明现在情况时,主句用 is,从句用一般过去时；说明过去情况时,主句用 was,从句用过去完成时.如：

It is three years since we was there. 自从（过去）到那儿以来,（到现在）三年已经过去了.
It was three years since we had been there. 自从（过去的过去）到那儿以来,（到那时）三年已经过去了.
