Summary现在完成时用法（二）此用法需注意两点：1）常与for,since引导的时间段的时间状语连用。2）动词使用延续性动词。

since,for的用法:since:自…...以来1)since+时间点He?has?stayed?here?since?5?o’clock.2)since+时间段+agoHe?has?stayed?here?since?5?hours?ago.3)since+从句(句子要用一般过去时态）She?has?taught?English?since?he?came?here.for:(长达）for+时间段Hehaskeptthebookfor2weeks.

since＋一段时间＋ago＝for＋时间段;sincetwoweeksago=fortwoweeks;Ihavekeptthelibrarybookforaweek.=Ihavekeptthelibrarybooksinceaweekago.在现在完成时态中，for与since引导的时间状语可以相互转换。

Itis+时间段+since+一般过去时的句子.1.他的爷爷已经去世2年了。2.Nick参军三年了。3.他离开深圳好长时间了。4.这本书我已借了4个月了。Itis2yearssincehisgrandpadied.Itis3yearssinceNickjoinedthearmy.ItisalongtimesinceheleftShenzhen.Itis4monthssinceIborrowedthebook.

含有for，since的现在完成时的用法歌诀:过去的动作或状态，一直持续到现在，for,since把时间带。歌诀
