瞬间性动词如arrive,join,die,get,come,buy,sell,leave,borrow,marry等，以及终止性动词如start,begin,finish等，在现在完成时的肯定形式中不能与“for+一段时间”的时间状语连用，但可以用在否定句或这些动词对应的状态动词中。为了表述这种意思，我们常用相应的延续性动词have,keep,be..等来代替非延续性动词。Tips:5/22/202310浠水二中常见终止性动词与延续性动词(或状态动词)的对应关系如下:come/go/arrive/get/reach/move------open-----die------close----become---borrow---begin/start-----puton----leave-----buy-----fallasleep----end/finish-----catchacold-----jointhearmy----jointheParty----→Mybrotherfortwoyears.→Mybrotherfortwoyears.bein/atbeopenbedeadbeclosedbekeepbeonwearbeaway(from)havebeasleepbeoverhaveacoldbeinthearmy/beasoldierbeintheParty/beaPartymemberhasbeeninthearmyhasbeenasolider5/22/202311浠水二中辨析havebeento和havegonetoMyfatherhasgonetoShanghaiforameeting.他（已经）去了上海。MyfatherhasbeentoShanghaiforameeting.他（曾经）去了上海。havebeentosomeplace.曾经去过某地，已经回来．hasgonetosomeplace.某人去了某地，还没有回来．5/22/202312浠水二中现在完成时﹠一般过去时Ilostmypenyesterday.Ihavelostmypen.Heworkedinthathospitalfor8years.

5/22/202313浠水二中与一般过去时的用法比较一.现在完成时和一般过去时都是说过去的事情，但现在完成时注意的不是事情本身，而是强调事情与现在保持的某种密切联系（如现在的结果，影响,一直延续到现在等）;而一般过去时，则只讲述发生在过去的动作和事情与现在没有关系。
