awhilenow.现在完成时未完成用法延续性动词与非延续性动词“未完成”句式延续性动词非延续性动词转化方法用法：现在完成时表示动作或状态从过去某时开始，一直延续至今，还可能继续下去。这种用法称为“未完成用法”。现在完成时用法三标志词：常与for或since引导的时间状语(从句)连用。since+过去时间点“自从…”，用来说明动作的开始时间；for+时间段“持续了…”，用来说明动作延续的时间长度。for+时间段since+过去时间点since+过去时的从句未完成的句式（1）现在完成时+for+一段时间例：我好久没有见到她了。

Ihaven’tseenherforalongtime.（2）现在完成时+since+表示过去的时间点例：自1984年以来，史密斯先生就在这里工作。

Mr.Smithhasworkedheresince1984.（3）现在完成时+since+从句例：自上大学以来他学了大约5000个英语单词。Hehaslearnedabout5000Englishwordssincehewenttocollege.谓语动词用延续性动词，可以用

有for或since的肯定句中。现在完成时态中带有for或since的句子，动词需为延续性动词。在现在完成时的句子中，若含有for或since引导的时间状语,则句中谓语一定要用延续性动词。（2）非延续性动词转换为延续性动词

①将非延续性动词转化为“be+形容词或副词”begin(start)(开始)gothere(去哪里)comeback(回来)comehere(来这里)beonbetherebebackbehereopenclosediebeopenbeclosedbedeadbeoverbeinbeawayfinish

②有的非延续性动词可以转化为意思相同的延续性动词：borrow→keep(借)

become→be(成为)receive→have(收到)gotosleep→
