Grammar Fcus
含有fr，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，fr、since 把时间带。 fr+时间段 since
时间段+ag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fr, 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, wrk, study, be pen, be clsed, keep, have, be away, be married, be asleep, be ill等。
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fr+一段时间，since+时间点连用。eg：He has lived here fr 6 years. 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：I have left here fr 3 years. × I haven't left here fr 3 years. √
谓语动词用延续性动词，可以用hw lng提问。
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。 I have bught the bk fr five years. ( ) I’ve had the bk fr five years. ( )2.非延续性动词/ 短暂性动词(cme, g, leave, buy …)可以用于现在完成时。但不能用于带有fr或是since的肯定句中。He has left Beijing fr a week. （ ）He has nt left Beijing yet. ( )
