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。for+时间段since时间段+ago过去的时间点过去时的从句现在完成时表示动作或状态在过去已经开始，持续到现在可能还要持续下去，常和for,since引导的表示一段时间的时间状语连用，谓语动词多用延续性动词。如：live,teach,learn,work,study,beopen,beclosed,keep,have,beaway,bemarried,beasleep,beill等。presentationGrammar现在完成时的持续型用法动词：

延续性动词：表示能够延续的动作；表示经过和经历；常与for+一段时间，since+时间点连用。eg：Hehaslivedherefor6years.

非延续性动词：表示不能延续的动作，这种动作发生后立即结束；表示行为的结果。在肯定句中不能和表示时间段的状语连用；在否定句中则可以。eg：Ihave

leftherefor3years.×

Ihaven'tleftherefor3years.√谓语动词用延续性动词，可以用howlong提问。Grammarpresentation

此种用法中表示持续性的动作或状态的动词必须是延续性动词(否定句除外)。1.这本书我买了5年了。

boughtthebookforfiveyears.()I’ve

hadthebookforfiveyears.()2.非延续性动词/短暂性动词(come,go,leave,buy…)可以用于现在完成时。但不能用于带有for或是since的肯定句中。HehasleftBeijingforaweek.（）HehasnotleftBeijingyet.()×√句中动词的特点×√presentation1.转换为相应的延续性动词，用于现在完成时。
