过去时表示过去的一个动作，而且通常含有“过去时，而现在不是的”的含义。比如，我以前是一名学生。我以前是做翻译的。I was a student.I was a translator.这种用一般过去时表示的就是以前是怎么的，但是现在已经不是了。现在完成时表示过去的动作持续到现在，以前是这样，现在还是这样。还可以表示过去的动作对现在造成的影响。I have had lunch.我吃过午餐了，隐含意思现在不饿；I have watered the flowers.我已经浇过花了，隐含意思你不需要再浇水了。再次对比过去时和完成时所表达的意思 I have watered the flowers.我已经浇过花了。不用继续浇水了 I watered the flowers.我浇过花了。只是说明我早上干了啥 基本结构 肯定句：主+have 动词过去分词+宾语 I have finished my homework.否定句：主+have 动词过去分词+宾语 I havent finished my homework.疑问句：Have+主语+动词过去分词+宾语 Have you finished your homework?主语是第三人称单数的时候，have 改成 has 动词的过去分词要记全，这是基础，过去分词跟过去式一样重要 什么情况下需要用到现在完成时？1.有明显的提示词 与我们之前学过的时态一样，过去时可能会出现 yesterday,last；现在进行时可能会出现 now,look；将来时可能会出现 tomorrow,next；一般现在时可能会出现 usually,often。现在完成时有时也有提示词，如 already,yet,ever,never,before,for+时间段,since+时间点 I have already been to Guangzhou three times.我已经去过广州三次了。I havent finished my job yet.我还没做完我的工作呢。I have never seen this kind of bird before.我从来都没有见过这种鸟。Have you ever visited the Summer Palace?你参观过颐和园吗。He has

现在完成时的完成用法指的是动作发生在过去某一时刻并已结束，但该动作对现在产生了影响，与现在情况具有因果关系。例如：He has turned off the light.他已把灯关了。(动作结束于过去，说明了是现在的情况-灯现在不亮了。)现在完成时完成用法的特点是动作不延续，即瞬间动词，因此，该时态只能与表示不定的过去时间状语(如：already，yet，before，recently 等)、频度时间状语(如：never，ever，once等)、包括现在时刻在内的时间状语(如：this morning month year.，today 等)连用。例如：Have you found your pen yet？你已找到你的钢笔了吗？2.现在完成时的未完成用法 现在完成时的未完成用法指的是动作开始于过去某一时刻，一直延续到现在，或可能还要继续下去。例如：He has lived here since 1978.自从 1978 年以来，他一直住在这儿。(动作起始于 1978年，一直住到现在，可能还要继续住下去。)I have been in the army for more than 5 years.我在部队已经呆了五年多了。(动作开始于5年前，一直延续至今，有可能还要继续下去。)此种用法的句中常需一个表示一段时间的状语(由 since 或 for 引导)，或表示与现在时刻相连的时间状语(如：up to now，so far 到目前为止)等。例如：I have heard nothing from him up to now.到目前为止我没有他的任何消息。注意：现在完成时的未完成用法只适用于延续性动词，不可用于终止性动词，即瞬间完成或延续时间很短的动词。3.延续性动词和瞬间性动词的概念 主语动词要变化三单练习语法概念主语是第一人称单数动词要不要变化称复数动词要不要变化用的适当形式填空二一般过去时精品资料欢迎下过去式三现在进行时概念表示现阶段或说话时正在进行的动作及行为时精品资料 欢迎下载 英语中，动词按其动作发生的方式、动作发生过程的长短，可分为延续性动词和瞬间性动词。延续性动词表示能够延续的动作，这种动作可以延续下去或产生持久影响。如：learn,work,stand,lie,know,walk,keep,have,wait,watch,sing,read,sleep,live,stay 等。瞬间性动词也称非延续性动词、瞬间动词或短暂性动词，表示不能延续的动作，这种动作发生后立即结束。如 open,close,finish,begin,come,go,arrive,reach,get to,leave,move,borrow,buy 等。It rained at eight yesterday morning.(误)rain 为延续性动词，而 at eight 表示点时间。上句可改为：It began to rain at eight yesterday morning.(正)I have borrowed the book for 2 months.（误）borrow 是“借”不能做借这个动作做了 2 个月吧 I have kept the book for 2months.（正）换成 keep 这个动词，保持，借到手了就拿了 2 个月-When did you get to know Jack?-Two years ago.-Then youve known each other for more than two years.-Thats right.附加延迟动词与瞬间动词转换表（部分）：注意 be 的作用很大 瞬间动词 延续动词 瞬间动词 延续动词 put on wear end be over buy have join be in borrow keep go there be there become be get to/arrive/reach be in die be dead come back be back move to live in catch a cold have a cold His father has died.die：死亡，这个动作做完就没了，后面不能加延续的时间
