一般过去时理念一、基础知识点1.定义:表示过去发生的某个动作或状态以数轴为例过去将来过去发生的动作或者是状态0(这个动作和状态对现在没有影响)0点表示现在2.构成:主语+动词的一般过去式+其他3.标志词(即时间状语):yesterday昨天yesterday+时间thedaybeforeyesterday前天last+时间lastnight/week/month/yesterday时间段+ago之前fivedaysagobefore在….之前句子中有介词+表示过去时间的名词构成的短语:如in2019justnow刚才once曾经then那时this+时间例如(thismorning)请记住:thismorning(今天早上)往往动作已经发生用过去时,如果事情没有发生,我们就用一般将来时。例如:thismorningIwillseeadoctor.4.动词过去式的变化规则:⑴一般情况直接在词尾加+ed如:cook-cookedwash-washed⑵以不发音的e结尾的动词,在词尾+d如:like-likedlive-lived⑶以重读闭音节结尾的动词,双写最后一个字母再在词尾+ed如:stop-stoppedshop-shoppedplan-planned计划⑷以辅音字母+y结尾的动词,要改y为i再加ed如:study-studiedcarry-carried运送,搬运另外须记不规则动词的一般过去时变形。(不规则变化常考)请熟记英语教材p106和p1075.一般过去时涉及的三种句型肯定句:直接根据时态变动词否定句:两种情况(第一种即行为动词主谓宾didn't+动词原形;第二种即be动词主系表was/were+动词原形)疑问句:两种情况(第一种即行为动词疑问句did放在主语前且行为动词为原形yes.主语+did/No.主语+didn’t;第二种即be动词疑问句be动词was/were提前、回答用yes.主语+was/wereNO.主语+wasn’t/weren’t)做题一般过去时的做题步骤:(和数学很相似)第一步:找句中的时间状语(即表示时间的标志词)找到时间标志词的就直接可以判断出是一般过去时;如果没有明确的时间状语,有如下的方法:1.联系上下文判断时态,如果是疑问句填空我们就通过答句判断时态,如果是答句填空我们就通过疑问句判断时态;2.and连接前后的动词时态一致,例如:theytalked,laughedandwalkedtothevillage.第二步:判断句子的动词时be动词还是行为动词1.be动词肯定:was、were否定:wasn'tweren't2.行为动词:规则变化还是非规则变化理念思维导图做题思维导图练习题:(请画出第二题的时间关键词)一、写出下列动词对应的过去式或原形is________isn’t______go________learnt_________stop_______can______worried_______say________forgot_______stood______has_______run________hear_______see_______knew______bought______二、用所给动词的正确时态填空。1.What______she______(find)inthegardenlastmorning?She_______(find)abeautifulbutterfly.2.How_______(be)Jim'sweekend?It_______(benot)bad.3.________(be)yourmotherasalesassistantlastyear?No.she__________.4.I_______(have)anexcitingpartylastweekend.5._________she______(practice)herguitaryesterday?No,she_________.7.What________Tom_____(do)onSaturdayevening?8________(watch)TVand______(read)aninterestingbook.9.Theyall______(go)tothemountainsyesterdaymorning.10.She______(notvisit)herauntlastweekend.She________(stay)athomeand______(do)somecleaning.11.When______you______(write)thissong?I_______(write)itlastyear.12.Myfriend,Carol,________(study)forthemathtestand____(practice)Englishlastnight.三、按要求变换句型。1.Fatherboughtmeanewbike.(同义句)Fatherbought______________________________me.2.Frankreadaninterestingbookabouthistory.(一般疑问句)_______Frank_______aninterestingbookabouthistory?3.He’scleaninghisrooms.(划线提问)________he_______?4.Whynotgooutforawalk?(同义句)_______________________outforawalk?5.ThomasspentRMB10onthisbook.(否定句)Thomas______________RMB10onthisbook.四、句型转换。TheyreadEnglishlastnight.否定句:__________________________________________一般疑问句:________________________________________肯定/否定回答:____________________________________对划线部分提问:____________________________________
