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
