规则动词的过去式词尾变化有几种：1．一般情况下加ed，如watched,planted,watered,pulled,climbed,picked。2．以不发音字母e结尾的加d，如liked,moved,tasted。3．以辅音字母加y结尾的变y为i再加ed，如study——studied。4．以1个元音字母加1个辅音字母结尾的重读闭音节，双写最后一个辅音字母再加ed，如stop——stopped。词尾读音有3种：a．在浊辅音和元音后读[d]，如lived,watered,listened,played。b．在清辅音后读[t]，如liked,helped,watched。c．在[t],[d]音后读[Id]，如planted,wanted,handed(上交)。不规则动词的过去式变化则没有什么规律，请大家背熟记牢：sit——satthrow——threwam,is——wasdrink——drankdraw——dreware——weresing——sangfly——flewdo——didbegin——begangrow——grewhave,has——hadswim——swamput——putmay——mightgive——gavecut——cutcan——couldring——ranglet——letshall——shouldrun——ranread——readwill——wouldride——rodecatch——caughtgo——wentwrite——wroteteach——taughteat——atedrive——drovethink——thoughthear——heardkeep——keptbuy——boughtsee——sawsleep——sleptfight——foughtfind——foundsweep——swepthold——heldwear——worefeel——felttell——toldmeet——metcome——cameget——gotmean——meantbecome——becamemake——madespeak——spoketake——tooksay——said1）is,am-wasare-were2)begin-beganring-rangdrink-drankswim-swamgive-gavesing-sangsit-satrun-ranhave-hadmake-madecome-cameeat-ate3)write-wroteride-rodespeak-spokedrive-drovestand-stoodtell-toldwin-wonget-gottake-took4)sleep-sleptsweep-sweptfeel-feltkeep-keptspell-speltspend-spentbend-bentmeet-metgo-went5)know-knewfly-flewblow-blewgrow-grewthrow-threwdraw-drew(glow-glowed)6)teach-taughtcatch-caughtbuy-boughtfight-foughtthink-thought7)find-foundhear-heardsay-saidlie-laysee-sawlearn-learntmean-meant8)put-putread-readcut-cutlet-let

如果是单纯的强调过去发生的用一般过去时强调过去某一点正在做什么用过去进行时,一般句子都会有提示,例如：Iwasreadingwhenhecamein.就是说在他进来的那一时间点上,我正在读书.如果句子描述的东西发生在过去,用的是过去时,那里面若还描述了过去时就用过去完成时,例如：Hesaidhehadbeenthere."said"就表他是在过去说的,而"hadbeen"就表示他是在说前去过。望采纳

①一般情况下在动词原形后直接加-ed.如：wanted,played. ②以不发音的字母e结尾的动词,去掉e再加-ed.如：hoped,lived. ③重读闭音节单词需双写最后一个辅音字母再加-ed.如：stopped. ④以辅音字母+y结尾的动词变y为i,再加-ed.如：studied,worried. 规则动词过去式的读音也有规律可循.请记住：清后[t],元浊[d],[t] [d]之后读[Id]. ①清辅音[p] [k] [f] [s] [F] [tF]等后,ed要读[t].如：worked,finished. ②元音或浊辅音[b] [g] [v] [z] [m]等后,ed要读[d].如：lived,called. ③[t]或[d]后,ed读[Id].如：started,needed. b.不规则动词变化 be动词过去式有两种形式,主语是第一、三人称单数形式使用was,其他人称用were 其他的大概有几类 一、AAA型（原形、过去式和过去分词同形）： cost cost cost cut cut cut let let let put put put read read read 二、ABB型（过去式与过去分词同形）： bring brought brought build built built buy bought bought catch caught caught dig dug dug feel felt felt find found found get got got have had had hear heard heard hold held held keep kept kept ※learn learnt learnt leave left left lend lent lent make made made meet met met pay paid paid say said said sell sold sold send sent sent shine shone shone sit sat sat sleep slept slept ※smell smelt smelt spend spent spent stand stood stood teach taught taught tell told told think thought thought understand understood understood 三、ABC型（原形、过去式和过去分词各异）： be was?were been begin began begun blow blew blown break broke broken do did done draw drew drawn drink drank drunk drive drove driven eat ate eaten fall fell fallen fly flew flown forget forgot forgotten give gave given go went gone grow grew grown know knew known lie lay lain ride rode ridden ring rang rung see saw seen show showed shown sing sang sung speak spoke spoken swim swam swum take took taken throw threw thrown wake woke woken wear wore worn write wrote written 四、ABA型（原形与过去分词同形）： become became become come came come 五、AAB型（原形与过去式同形）： beat beat beaten
