1、Unit 10 Lesson 58 Ms. Lius Speech现在完成时讲解,春天还会远吗 ? will it still be far in spring?,冬天已经来了, Winter has already come,现在完成时态,Winter has already come.,现在完成时的构成形式,have done has,助动词,过去分词,用来表示之前已经发生或完成的动作或状态，而其结果却和现在有联系: 动作或状态发生在过去,但它的影响现在还存在。 They have left.(leave) -他们已经离开了,也就是说现在他们人不在这里 I have had my lunc

2、h.(have) -我已经吃过午饭了,也就是说我现在不饿,现在完成时的含义,也可表示持续到现在的动作或状态。 He has learned English since 2001. -从2001年开始学的,现在还在继续学着呢,Since+时间点 现在完成时的标志， have +done, has +done,now,past,future,一般过去时,现在完成时,现在完成时 表示的是在过去某个时间开始并持续到现在的动作/状态, 或者发生在过去却对现在造成的影响,和现在完成时连用的时间状语,和现在完成时连用的时间状语,和现在完成时连用的时间状语,延续性动词：表示可以延续一段时间的动作或状态。如：b

3、e,drink,fly,eat,keep,lie,live,rain等。 瞬间性动词：表示不能延续的动作，即动作发生后立即结束。如：begin,arrive,borrow,buy,close,come, leave,lend,marry,等。 瞬间性的动词是不能持续的，所以不能和表示一段时间的状语连用。,比较延续性动词与瞬间性动词,since 用来说明动作起始时间 “自从” for用来说明动作延续时间长度 “长达” +时间 段 I have lived here for more than twenty years. 时间 段,比较since和for,I have lived here sin
