1. before可用于表示时间。首先，可以表示“先于，在…以前”，其后可以跟表示具体日期、时间等的名词或数词，也可以跟表示时间或动作的名词。其次，可以表示“在做…之前”，后接 v -ing。再次，可以表示“紧接在…之前”。before用于否定句还可表示“直到…为止”。注意before之后只能接表示时间点的名词，而不能接表示时间段的名词。
2. before可用于表示动态或静态的位置，意思是“在…之前”，与behind相对。
3. before可用于表示顺序或排列上的“在…之前”或“居于…之前”，与after相对。引申可用于表示比较，即在等级、价值、重要性、能力等方面的“在先”“优于”“重于”。再引申则可用于表示对某事物的优先选择，即“宁可”或“与其…宁可”。
4. before还可表示“面对，在…眼前，在…面前”“有待于去完成”“在审理中，由…考虑”“在…压力下”等。

1. before主要引导时间状语从句，意为“先于”“…之后才”“(不多久)就…”。当主句是将来时时，从句谓语动词须用现在时；当主句是一般过去时或过去完成时时，从句常用过去时。before引导的时间状语从句不能用于否定式。
2. before还可用于barely〔scarcely〕...before结构，意为“刚…就…”。
3. before还可引导让步状语从句，意思是“宁愿…也不…”。
4. before引导的从句常用省略句型。

1. before用作副词时,意思是“以前,在前面”,表示从较近的过去至较远的过去。用作时间状语泛指以前、不与具体时间连用时，谓语动词可以用一般过去时,也可用现在完成时,前者只表示“过去发生过”,后者则强调“对现在有影响”。
2. before与具体时间连用时,一般置于其后，谓语动词通常用过去完成时。
3. before也可表示空间或位置的“在前，在前面”，还可表示运动“到前面”。

   All day, as for three days before, we planted trees.

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：

   （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。

   他们很快就回来了。
