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。

before
before: [OE] Before is a Germanic compound, made up of *bi- ‘by’ and *forana ‘from the front’ (the resulting *biforana entered Old English as beforan). The second element, *forana, is a derivative of *fora, source of English for; this originally meant ‘before’, and only gradually developed the senses we are familiar with today.=> for
before (adv., prep.)
Old English beforan "before, in front of, in the presence of, in former times," from Proto-Germanic *bi- "by" + *forana "from the front," adverbial derivative of *fora (see fore (adv.)). Compare Old Frisian bifara, Old Saxon biforan, Old High German bifora, German bevor. Contrasting before and after in illustrations is from Hogarth (1768). Before the mast in old sailing ships denoting "common sailor," is from the place of their berths, in front of the fore-mast.
