1、动词过去式变化规则:1.一般在动词末尾加-ed,如:pull-pulled,cook-cooked2.结尾是e加d,如:taste-tasted3.末尾只有一个元音字母和一个辅音字母的重读闭音节,应双写末尾的辅音字母,再加-ed,如:stop-stopped4.以“辅音字母+y”结尾的,变y为i,再加-ed,如:study-studied5.不规则动词过去式:am,is-was,are-were,do-did,see-saw,say-said,give-gave,get-got,go-went,come-came,have-had,eat-ate,take-took,
2、run-ran,sing-sang,put-put,make-made,read-read,write-wrote,draw-drew,drink-drank,fly-flew,ride-rode,speak-spoke,sweep-swept,swim-swam,sit-sat... 关于规则动词的过去式变化(在词尾加-ed)大家已经了如指掌了,但对那些不规则动词的过去式的变化,记忆起来总是有一定难度。这里教给大家一些“妙招”,不妨一试哦! 1.中间去e末尾加t,如:keep→kept,feel→felt,sleep→slept,sweep→swept 2.结
3、尾d变t,如:build→built,lend→lent,send→sent,spend→spent 3.遇见i改为a,如:ring→rang,sit→sat,drink→drank,sing→sang,swim→swam,begin→began,give→gave 4.“骑(马)”“开(车)”“写(字)”——把i变o,如:ride→rode,drive→drove,write→wrote 5.“想”“买”“带来”“打仗”——ought换上,如:think→thought,buy→bought,bring→brought,fight→fought 6.“教书”
4、“抓住”——aught切莫忘,如:teach→taught,carry→caught 7.ow/aw改为ew是新时尚,如:know→knew,grow→grew,throw→threw,draw→drew 8.“放”“让”“读”过去式与原形一样,如:put→put,let→let,read→read/red规则动词的过去式变化如下:一般情况下,动词词尾加-ed,如:workedplayedwantedacted以不发音的-e结尾动词,动词词尾加-d,如:livedmoveddecideddeclinedhopedjudgedraisedwiped以辅音字母+y结尾
5、的动词,把-y变为-i再加-ed,如:studiedtriedcopiedjustifiedcriedcarriedembodiedemptied以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加-ed,如:stoppedbeggedfretteddraggeddroppedplanneddotteddripped注:不规则动词的过去式变化规律性不强,须多加记忆。go-wentmake-madeget-gotbuy-boughtcome-camefly-flew动词过去式,过去分词不规则变化AB型cancouldshallshouldwillwouldmaym
