A before since B since when C since before D when before
考察的知识点是什么,since和before,when的区别
when是不是加和时间点连用。
比如：It's 10o'clock( ) I saw you last
是不是用when
.

这题选C吧!
since表示“自...之后”,动作发生在一件事情之后,如It's a long time since I saw you last.自上次见到你之后有一段很长的时间.可以根据时态saw看出,事情发生在过去.
before表示“在...之前”,动作发生在一件事之前,如it will be a long time before we see each other again在我下次再见到你会有一段很长的时间,从时态will可以看出,事情发生在将来.
when表示“当.”,动作与事件是同时发生的!
