back,趁热打铁,会议已经开始了,.,会议已经开始五分钟了。,友情提醒：不要得“,延续性动词狂热症,”，一定要分清楚,是否和延续性时间连用。,now,past,过去完成时，表示过去某时之前的动作或状态，也就是我们通常所说的 过去的过去，常搭配的时间短语有,by/by the end of+,过去的时间,，也广泛使用于,主句为过去时的宾语从句,中。,e.g.We _ (learn)1500 words,by last year,.,He,said,he _(lose)his money.,had learnt,had lost,The students _ (dance)when the teacher came in.,The students _,（,fall alseep)when the teacher came in,.,易混淆知识点,were dancing,had fallen alseep,为什么同样的时间状语，可是主句的时态却不一样呢？聪明的你能回答吗？,Work out the rule:,有了,when,引导的过去时的时间状语从句，如果主句的动作和从句的动作,_,发生,则主句用,过去完成时,（主句的动词一般为,_,动词），如果主句的动作和从句的动作,_,发生,则主句要用,过去进行时,（主句的动词一般为,动词）。,先后,同时,短暂性,延续性,巩固练习,have learnt,had begun,has changed,（来源于中考指南）,1.They
