1.Before同ago的比较：
表示“早于现在多少时间前”，用ago。
He started five minutes ago.
表示“早于过去某时多少时间前”，通常用before 。

英美人也有用ago，觉得语气比较生动。
表示“早于将来某时多少时间前”，也用before。

All day, as for three days before, we planted trees.
同以前的三天一样，我们一整天都在种树。
3.before既可作副词，也可作介词，如在three hours before中为副词。在before three o'clock中为介词，但要注意before不能在表示“一段时间”的词前作介词，不能说before a month，可说a month ago；
4.before long，属于习语，表示“不久以后”，同before a long time has passed意思一样。before very long也指“不久以后”，但比before long时间短；
5.要注意before的表达方式，不能说before five minutes of the accident，而是five minutes before the accident。其他表达方式如下：
A few minutes before the accident she called on me.
（不含the/for）
During the few minutes before the accident she had a chat with me.
（含the）
For a few minutes before the accident she had a chat with me.
（含for）
6.before作连接词，指“……以前”时，后接到从句中的动词一般不能用将来时。如不可以说He will arrive before she will start，可以说He will arrive before she starts。
若是表示“长久以后才会发生的事”时，可用将来时。
It will not be long before they come back.
他们很快就回来了。
