一般过去时与现在完成时的区别 A 从形式结构上区别一般过去时的形式结构为 1 主语 动词的过去式 其它 如 Hewasateacher 他当过教师 Mr Browngaveustalkyesterday 布朗先生昨天给我们做个报告 Theoldmantoldaninterestingstory 那位老人讲了一个很有趣的故事 2 现在完成时的形式结构为 主语 have has 动词过去分词 其它 如 WehavelearnedtwothousandEnglishwords 我们已经学过了两千个英语词 ShehasgonetoBeijing 她已经去北京了 B 从状语上区别1 一般过去时常用的副词状语有 then justnow等 以及时间状语有 yesterday lastweek twoyearsago等 如 Theywenttotheparkyesterday 昨天他们去公园了 LastyearIsawthatfilm 我去看过那部影片 2 现在完成时常与yet already ever neverjust等以及由for 时间名词和since 时间名词连用 如 Hehasalreadyfinishedhishomework 他已经完成了家庭作业 HaveyouseenthatTVplayyet 你看过那个电视剧吗 WehavestudiedEnglishforthreeyears 我们已经学了三年英语了 C 从否定 疑问结构上区别1 一般过去时的否定式 疑问式多是借助动词did来体现 be的疑问式除外 如 Tomsaidaword 否定式 Tomdidn tsayaword 疑问句 idTomsayaword 反意疑问式 Tomsaidaword didn the 2 现在完成时的否定式 疑问式多是借动词have has 来体现的 如 Youhavelookedupthatword 否定式 Youhaventlookedupthatword 疑问式 Haveyoulookedupthatword 反意疑问式 Youhavelookedupthatword haventyou 1 since与forsince可接时间点 或从句 从句用一般过去时 for接时段 这两词都是回答howlong的 如 since1990 sincetwoyearsago fortwodays 2 already yet never before just都可以用于完成时 但用法不尽相同 already用于肯定句的陈述句中间 yet用于否定句或疑问句末 never是 从来没有 之意 just是 刚刚 刚才 之意 都用于句中 before当副词用 与表一段时间的词连用用于完成时 即时间段 before 如twoyearsbefore 但注意与之同义的ago 是这样用的 时间段 ago 用于一般过去时 3 现在完成时与一般过去时的区别现在完成时表示过去发生或已经完成的某一动作对现在造成的影响或结果 或表示过去已经开始 持续到现在的动作或状态 一句话 现在完成时与现在有联系 而一般过去时 发生在过去但与现在没有联系 且各自的时间状语明显不用 延续性动词表示是动作是一种延续的动作 这种动作可以延续下去或产生持久的影响 Eg study work keep have wait sing sleep live等 4 延续性动词与终止性动词 终止性动词表示的动作不能延续 即动作发生后立即结束 产生某种结果 动作不能再继续下去 Eg come leave die arrive begin finish buy borrow open等 记住下列终止性动词改为延续性动词的表达法 A 动词改为 be 相应的介词 如 come bein B 动词改为 be 对应的形容词 如 close beclosedopen beopendie bedeadfinish end beovergetup beupleave beaway from begin start beongoout beoutfallasleep beasleepC 其它改法如 become bebuy haveborrow keepjointhearmy beinthearmy beasoldier jointheParty beintheParty beaPartymember catchacold haveacold 5 havebeento havegoneto havebeenin三个谓语动词含义不同 havebeento表示 曾经去过某地 但人已回 havegoneto表示 已去某地 人未回 它们都不能与since和for连用 havebeenin表示 已在某地呆 它可以与for或since连用 1 ZhaoLan already inthisschoolfortwoyears A was studyingB will studyC has studiedD arestudying2 Theyusually TVintheevening A watchB willwatchC arewatchingD watches3 Judy theGreatWalltwice andnowshestill togothere A wentto wantedB goesto wantsC hasgone wantsD hasbeento wants4 Shewillfindhimakindmanwhenshe moreabouthim A knowsB knowC willknowD isgoingtoknow5 WhatareyougoingtogiveourteacherforTeacher sDay I mnotsure MaybeI himsomeflowers A havegivenB willgiveC gaveD give6 Tom out Oh ishe Whattime he out A is did goB went is goingC hasgone did goD isgoing does go c A A B A D 用动词的正确形式填空 1 A Doyouwantapen B No Idon t I buy one 2 Howlong you study inthisschool 3 A Whereisyourmother B She go shopping 4 Myuncle teach heresincehecamehere 5 LiLei already give thenutstoPolly 6 MissGao teach Englishverywell 7 Listen Someone knock atthedoor 8 Myfather go toBeijing Heisn tathome 9 Mothersaidshe take metomyUncle sthenextSunday 10 youever be toLondon havebought have studied hasgone hastaught has teaches isknocking hasgone wouldtake been given Have 1 Mybrother foraweek A hashadacoldB caughtacoldC hascaughtacoldD gotacold2 They friendssincetheymetinBeijing A havemadeB havebecomeC havebeenD haveturned3 Howlong inthefactory A haveyoucomeB hasheinC willhebeD hashebeen4 I lllendyoumydictionary butyoucanonly foroneday A keepB borrowC lendD take5 MyfatherjoinedthePartyin1948 He aPartymemberforaboutfifty threeyears A hadbeenB hasbecomeC hadbecomeD hasbeen A C D A D 1 you return thebook Yes I I just return ittotheteacher 2 Leavethebookthere please I notfinish ityet I read itthisevening 3 I msurehe come toseemebeforehe leave Beijing 4 Doyouknowifhe come backinthreeweeks 5 A When you get yourmotorbike B I have itforaboutayear A you drive itmuch B Yes I use iteveryday A You drive verywell I never learn todrive B I learn oneyearago returned Have have returned haven tfinished willread have willcome leaves willcome get havehad did drive Do use mustdrive have learnt learnt 1 请问你们有关于化学方面的书吗 1 Excuseme haveyougotanybooksaboutchemistry 2 他们给了我知识并使我快乐 2 Theygivemeknowledgeandmakemehappy 3 一天图书管理员想出了一个主意3 Onedaythelibrariancameupwithanidea 4 你曾经坐飞机旅行过吗 4 Haveyouevertravelledonaplane 是的 只有一次 Yes justonce 5 我刚刚读完这本书 5 I vejustfinishedreadingthebook 1 我曾经去过纸厂 1 I vebeentoapaperfactory 2 他已经吃
