现在完成时1.表示过去发生或完成的某一动作对现在造成的影响或结果。①Have yu read that stry? 你读过那个故事吗？（读这一动作发生在过去，对现在造成的影响为： 是否知道故事中的内容）②I have bught tw apples. 我买了两个苹果。（买这一动作发生在过去对现在造成的结果是：拥有两个 苹果） 在学习这一概念的同时，还应注意常与现在完成时态连 用的几个副词： already，just多用于肯定句中， yet，ever，never多用于疑问句和否定句中。如： I have already finished my hmewrk. 我已经做完家庭作业。
1. He has just had supper. 他刚吃过晚饭。2. Have yu ever sung this English sng? 你曾唱过这首英文歌吗？3.They haven't dne the hmewrk yet. 他们还没有做作业。4. We have never seen a film. 我们从来没有看过电影。5. He has died. 他死了。
2.表示过去开始的动作持续到现在，甚至还可能继续下去； 常和表示从过去某一时刻起延续到现在（包括“现在”在内）的一段时间状语连用。如： They have lived here fr ten years .他们住在这儿有十年了。 She has taught in this schl since three years ag. 她从三年前开始就在这个学校教书。 We have knwn each ther since we were very yung. 我们从很小的时候就彼此认识。注意：用于这种用法中的动词必须是表示连续的动作或状态的词，如：live、wrk、teach、study、stay、wait、knw、be、have、learn、wear、walk、sleep等，这类动词叫做“延续性动词”。英语中还有另一种动词，如：buy、jin、becme、begin、fall、cme、g、hear、die、clse、pen、leave、brrw、等，它们只表示短暂的动作，不能表示一个延续的状态，这类动词叫做“瞬间性动词”，它们可以用于现在完成时， 但是不能和表示一段时间的状语连用。
