一般过去时态讲解与练习一般过去时主要表示过去某时发生的动作或情况。结构是“主语+动词的过去式”可以从以下几个方面来理解：1、过去某个时间所发生的动作或存在的状态，句中有明确的表示过去的时间状语如：yesterday（昨天）,lastnight（昨晚）,lastweek（上个星期）,fourdaysago（四天前）,in2002（在2002年）,justnow（刚才）,thedaybeforeyesterday（前天）等。表示在过去某个时间发生的动作或情况。e.g.Iboughtanewshirtyesterday.Hewasaworkertwoyearsago.2、过去一段时间内，经常性或习惯性的动作。e.g.WhenIwasachild,Ioftenplayedwithfire.LiLeialwayswalkedtoschoollastterm.3、谈到已故人的情况时多用过去时。e.g.LuXunwasagreatwriter.4)有些发生时间不是很清楚的情况，实际是过去发生的，也应用过去时态。e.g.Whatdidyousay?动词过去式的构成：be动词的过去式为was,were;行为动词的过去式有规则变化和不规则变化两种，规则变化有以下几种情况：1)直接在动词原形末尾加-ed.e.g.work-----worked;ask------asked;2)以e结尾的动词只加-d.e.g.arrive-----arrived;like-----liked.3)末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed.e.g.shop-----shopped;4)以"辅音字母+y"结尾的动词,先把y变成i,再加-ed.e.g.carry----carried;study------studied.不规则动词变过去式见同学们课本的最后一页,e.g.fly------flew;break-----broke;teach-----taught.这些需要象生单词一样记住.其句式变化分为两种情况：1)含有be动词的依然在be上做文章.e.g.Iwasbornin1980.Iwasnotbornin1980.Wereyoubornin1980?2)含有行为动词的变否定句要在行为动词前加助动词didn't.,同时把动词变成原形;变一般疑问句,在句首加助动词did,同时把动词变成原形.e.g.Iboughtagiftformymumyesterday.Ididn'tbuyagiftformymumyesterday.Didyoubuyagiftforyourmumyesterday?课后练习一、请写出下列动词的过去式。wantarriveenjoyshopisseeareeat二、指出下列句中的一处错误，并改正。1.Wegotoschoolearlyyesterday.__________2.Shebuysadresslastweek.___________3.Didyoulikedplayingfootball?_______4.---Didyouhaveagoodtrip?---No,Idid._______5.IenjoiedChineseverymuch._______三、翻译下列句子，每空一词。1.你昨晚去哪了？Where______you_______lastnight?2.我们昨天没有在学校。We__________atschoolyesterday.3.我两小时前在家里。Iwasathome____________________.4.你上周六去了动物园吗？_______you________tothezoolastSaturday?5.我去年不喜欢学数学。I_________likelearningmathlastyear.6.你昨天在哪儿呢？Where________youyesterday?7.詹妮喜欢看书。昨晚她看了一本英语书。Jennylikesreadingbooks.She_________anEnglishbooklastnight.8.上周六他做什么了？他和妈妈去购物了。---What________he_________lastSaturday?---He_________shoppingwithhismother.9.雷锋经常帮助其他人。LeiFengoften________otherpeople.10.我上周没有给你写信。I________________toyoulastweek.Ⅲ按照括号中的要求改写句子。1.Lucydidherhomeworkathome.（改否定句）Lucy______________________herhomeworkathome.2.Shefoundsomemeatinthefridge.（变一般疑问句)___________she_____________________meatinthefridge?3.Shestayedthereforaweek.（对划线部分提问）_______________________________she__________there?4.Therewassomeorangeinthecup.（变一般疑问句)_________there___________orangeinthecup?5.LiMingisatschoolnow.（用yesterday改写句子）LiMing_______atschoolyesterday.四、请用正确动词形式填空。1.I_________anexcitingpartylastweekend.（have）2.She_______athomeyesterdaymorning.（is）3.Tommy__________TVathisuncle’slastnight.（watch）4.Theyall_________tothemountainsyesterdaymorning.（go）5.Myfriend,Carol,________forthemathtestyesterdayevening.（study）6They____(be)onthefarmamomentago.7There____(be)ashopnotlongago.8Jenny____(notgo)tobeduntil11:00o'clocklastnight.9Danny_____(read)Englishfiveminutesago.10I_____(see)LiLei____(go)outjustnow.11He____(do)hishomeworkeveryday.Buthe__(notdo)ityesterday.12WhenIwasyoung,I_____(play)gameswithmyfriends.13When____you_____(write)thisbook?I_____itlastyear.14Didhe____(have)lunchathome?五、按照括号中的要求改写句子。11.Lucydidherhomeworkathome.（改否定句）Lucy______________________herhomeworkathome.12.Shefoundsomemeatinthefridge.（变一般疑问句)___________she_____________________meatinthefridge?13.Shestayedthereforaweek.（对划线部分提问）_______________________________she__________there?14.Therewassomeorangeinthecup.（变一般疑问句)_________there___________orangeinthecup?15.LiMingisatschoolnow.（用yesterday改写句子）LiMing_______atschoolyesterday.
