Before long he got married.不久他就结婚了。
2. long before

That had happened long before.那事老早就发生了。
注：long ago表示“很久以前”，指的是从现在算起的很久以前，通常与一般过去时连用：

(2)在……的很久以前，在还没有……的很久以前。如：
She had left long before his return [he returned].在他回来的很久以前她就走了。
He had worked in the factory long before he got married.在他还没有结婚的很久以前他就在这家工厂工作了。
注：此时的主句谓语通常用过去完成时，但有时也可用一般过去时(因为 before已体现了动作的先后关系)。如：
This happened long before you were born.这事在你还没出生以前很久就发生了。
It is [was, will be] long before......在……前需要很久。如：
It was long before he came back.过了好久他才回来。
