Whenwhere is used to refer to a point of origin, the prepositionfrom is required: Where did she come fromô When it is used to refer to a point of destination,the prepositionto is generally superfluous: Where is she goingô ( preferable toWhere is she going toô ). When it is used to refer to the place at which an event or a situation is located,the use ofat is widely regarded as regional or colloquial: Where is the stationô (not Where is the station atô ). The idiomatic phrasewhere it`s at, widely used in the 9'0`s to refer to .the current state of things,. is now largely passô, except when used for stylistic effect:
当where 被用来指起源方面时， 介词from 就需要用上： 她从哪里来ô 当它被用来指目的地时，介词to 就通常是多余的： 她要去哪里ô ( 比起她要向哪里去ô 更可取）。 当它被用来指事件所发生的场合或一种局面形势所处的地方时，使用at 则被广泛认作是地区性的或口语化的： 车站在哪里ô （而不是 车站位于什么地方ô )。 惯用语短语where it`s at 在20世纪'0年代广泛被用来指.事情的当前状态.，现已很大程度上过时了， 除非当我们用它来加强文体效果：
例句：
.Generally, I knew where he was at, but couldn`t always tell where he was coming from. (Robert M. Adams).See Usage Note at why
.通常来说，我知道他在什么地方，但我却不总能说出他从哪里来. （罗伯特·M·亚当斯）参见 why
