` 现在完成时的用法一、表示过去发生并且已经完成的动作对现在造成的影响或结果。
例如：你读过那个故事吗？Have you read that story?（“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）我买了两个苹果。
I have bought two apples.（“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）（一）、构成：“助动词have/has+动词的过去分词”（二）、句型结构：肯定式：主语+have/has+ 过去分词+其它。
如：I have just come back from Qinzhou.否定式：主语+have/ has not + 过去分词+其它。
如：I haven’t seen the TV play.一般疑问句：Have/ has+ 主语+ 过去分词+其它?如：Has Jack finished his homework?回答：肯定：Yes, 主语+ have/has .否定：No, 主语+ haven’t/ hasn’t.特殊疑问句: 特殊疑问词+ 一般疑问句？如：How long have you had the dog ?[当堂检测] 完成下列句子：1．李明还没看过这本书了。

Mum_____ _____that book.6.你去哪了？Where_____you_____ ?（三）、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：1、I have already finished my homework. 我已经做完家庭作业。
2、she has just had supper. 她刚吃过晚饭。
3、Have you ever sung this English song? 你曾唱过这首英文歌吗？4、They haven't done the homework yet. 他们还没有做作业。
5、We have never seen an interesting film. 我们从来没有看过有趣的电影。

8、You can come with us to the cinema when you have finished your homework.你做完功课可以和我们一起去看戏。
9、Most of them have already seen the movie. 他们中大多数人已经看过这部电影了。
10、How long have you lived here? 你住在这里多久了？（四）、现在完成时和一般过去时的区别:1、一般过去时只单纯表示过去的动作或状态，和现在不发生联系；如：I finished reading the book three days ago.2、现在完成时表示某一完成动作对现在造成的影响或结果，强调的是现在的情况。
如：I have finished reading the book now用一般过去时的情况：1).当有一个表示过去的时间状语, 如: last year , two days ago , yesterday , just now等时. --When did he leave ?--We weren’t in last night .--She often came to help me When we were very young .2). 单纯谈过去的动作，不涉及它对现在的影响时.--What did you have for your lunch?--When did you have supper?用现在完成时的情况：1).当有一个表示到现在为止这段时间的状，如recently , these days , so far , up till now, in the past 3 years, by the end of…，for+ 一段时间以及since引导的表示时间的状语从句时.--We have learned a lot since we came to this school .-- I haven’t slept very well these days.2).若谈一件已发生的事，主要考虑它对现在的影响的。
-- Have you had your lunch?-- Do you want more?Thanks, I have had enough.[即学即练]用括号里适当的词填空：1、We ___________(see) the film twice, we _____ it yesterday at school.2、—______ you ______ (read) the book before?—Yes, I ______.—When ______ you ______it?—Last month.3. Zhaoqing _____ (be) a small city 20 years ago, now it ______________ (become) famous all over the world.3、有些时间状语，如this morning , tonight , this month等，可用于现在完成时或一般过去时，但它们表达的意义不一样。
用于现在完成时则包括“现在”在内，而用于一般过去时则与现在无关。
例如；1). I have read this story this April .我今年四月份看过这个故事了。
（讲话时仍然是四月份）2).I read this story this April . 我今年四月份看的这个故事。
（讲话时四月份已过）3).I have written two letters this morning .今天上午我写了两封信。
（讲话时仍是上午）4).I wrote two letters this morning . 今天上午我写了两封信。
（讲话时已是下午或晚上）Exercise:—Why not go to see the film with me?—Because I _________ it.A、have seen B. will seeC. have sawD. saw2. —Hello! Could I speak to Mr. King, please?—Sorry, he’s ______ the supermarket.been at B. been toC. been onD. gone to3. I ______ already _____ my homework, I _______ it last night.have, finished, have finishedhave , finished, finishedfinished, have finished4. —Have you ______ your breakfast?—Yes, I have.—When ____ you _____ it?—1 hour ago.had, have had B. do, have , hadC. had, did, haveD. had, have, have二、.表示过去某一时间开始并一直延续到现在，甚至还可能继续下去。
常和表示从过去某一时刻延续到现在(包括“现在”在内)的一段时间状语连用。
一段时间的表达方法有两种:for + 一段时间: for a year , for two weeks, for three yearssince + 过去的某一时刻: since last week.一般过去时态的时间状语从句:since you came since you got home.1).They have lived here for ten years .2). She has taught in this school since three years ago.3).We have known each other since we were very young.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、work、teach、study、stay、wait、know、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：die、buy、join、marry become、begin、fall、come、go、hear、die、close、open、leave、borrow、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。
判断下列句子的正误：1). He has died .（）He has died for 2 years.（）He has been dead for 2 years. （）2). Helen has married. （）Helen has been married for 5 years. （）Helen has married for 5 years.（）瞬间性动词不能和表示一段时间的时间状语连用, 但是他可以转换成相应的延续性动词.1.直接用延续性动词buy–have catch(get) a cold –have a cold borrow—keep arrive/come/go /become—be put on– wear get up—be up2.转换成be+名词join the army – be a soldierjoin the Party –be a Party membergo to school– be a student3．.转换成be+形容词或副词die—be dead finish\end – be over begin—be onleave—be away fall sleep – be asleepclose/open – be closed/open marry— be married4．转换成be+介词短语go to school– be in schooljoin the army – be in the army[当堂检测] 选择填空1．The shop has been _______ for an hour.A. closeB. closingC. closed2.
