同近义词辨析

in front of, in the front of, before

这组词都有“在……前”的意思，其区别是：

in front of指在某地方之外的前面，即不在其中，多与静态动词连用，通常可与before通用。

in the front of指在某地方之内的前面，即在其中的前部分。

before指空间位置或时间的“在……前”。表时间时，反义词为after；指空间位置时，其反义词是behind。

before, ago

这组词都有“……以前”的意思，其区别是：

before或指从过去某一时间起向前推算的若干时间的以前，通常与过去完成时连用；或泛指以前，并不具体指若干时间以前，可使用现在完成的或过去时；还可指从将来某一时间起的若干时间以前。

ago指从现在起往前推算一段时间，始终置于所修饰的词之后，与一般过去时连用。
