三种动词形式变化（即原形，过去式，过去分词）一致的,cast-cast-castcost-cost-costcut-cut-cuthit-hit-hithurt-hurt-hurtlet-let-letput-put-putset-set-setshut-shut-shut,broadcast-broadcast-broadcastbet-bet-betburst-burst-burstrid-rid-ridspread-spread-spreadread-read-readspit-spit-spit,省略原形动词中两个相同的字母中的其中一个,然后在词尾叫-t,weep-wept-wept（流泪,哭泣）sleep-slept-sleptsweep-swept-swept（扫除,席卷）feel-felt-feltkneel-knelt-kneltsmell-smelt-smeltdwell-dwelt-dwelt（居住，停留）spell-spelt-speltspill-spilt-spilt（溢出,洒,使.流出）,这一类动词也有一个特点，那就是有字母组合-ee或者ll；同样的，也并不是说有这样的字母组合的不规则动词都是这样的变形了。flee-fled-fled,也基本符合这个规则，我们把它归入此类，不过它的过去式和过去分词是在词尾加-d,省略原形动词中两个相同字母中的其中一个，,speed-sped-spedfeed-fed-fedbleed-bled-bledmeet-met-metshoot-shot-shotlead-led-ledmislead-misled-misled,这类动词也是以字母-d或者-t结尾，中间的字母组合多数是-ee，当然这里把shoot和lead作为这一类归纳进去了。,把原形动词的最后一个字母-d改成-t,send-sent-sentlend-lent-lentbend-bent-bentspend-spent-spentbuild-built-built,这类动词的规则当然必须是以字母-d结尾的了。多数是-end这样的结尾。这里把build也归入了这一类了。而tend和mend属于规则变化的动词,有-ow,-aw,这些字母组合的动词，过去式中把这些组合改成-ew，过去分词在动词原形上再加字母-n,blow-blew-blowngrow-grew-grownknow-knew-knownthrow-threw-throwndraw-drew-drawnwithdraw-withdrew-withdrawn,这里特别要提醒同学们注意的是，flewflown并不是动词flow的过去式和过去分词，而是动词fly的过去式和过去分词，而动词flow是一个规则动词，它的过去式和过去分词是flowed-flowed:fly-flew-flownflow-flowed-flowed,另外，有-ow字母组合的动词slow也是规则变化。另一些的有-ow,-ew字母组合的不规则动词变化是过去式加-ed，过去分词在原形动词的基础上加-n,例如：show-showed-shownsow-sowed-sown（播种,散布）mow-mowed-mown（割草,扫射,）sew-sewed-sewn,含有字母组合-ind的动词，在过去式和过去分词中都变成-ound,find-found-foundwind-wound-wound,当然，这一类动词中也有一些例外，比如，mind就是一个规则变化的动词。,有字母组合-in或者-ing或者-ink的动词，过去式把字母-i变成-a，过去分词中把-i变成-u,begin-began-begunsing-sang-sungring-rang-rungspring-sprang-sprung（弹起，弹出,）sink-sank-sunkdrink-drank-drunkswim-swam-swum,此外，以-ing结尾的不规则动词，还有一种变化方式是将字母-i改成-u，过去式和过去分词一致,例如：sting-stung-stungswing-swung-swung,不规则动词以-m,-n,-l,-r结尾的，过去式和过去分词在原形动词词尾加-t或者-d,mean-meant-meantleanleant-leantlearn-learnt-learntdream-dreamt-dreamtburn-burnt-burntdeal-dealt-dealtspoil-spoilt-spoilthear-heard-heard,过去式和过去分词都有-ought的,think-thought-thoughtfight-fought-foughtbuy-bought-boughtbring-brought-broughtseek-sought-sought,另外有两个动词，原形动词以-ch结尾的，过去式和过去分词都有-aught的,我们也把它们归入了此类teach-taught-taughtcatch-caught-caught,动词以元音字母-i加辅音字母加不发音的-e结尾的，一般是在过去式中将字母改成-o，过去分词在原形动词基础上加-n,或者双写这个辅音字母再加-n,arise-arose-arisenrise-rose-risenride-rode-riddenwrite-wrote-writtendrive-drove-drivenstrive-strove-strivengive-gave-given,另一种情况是，过去分词中去掉这个不发音的-e，然后过去分词双写这个辅音字母再加-n的，例如：hide-hid-hiddenbite-bit-bitten,有-ea或者-ee或者-oo的字母组合的不规则动词，过去式是将这个字母组合改成-o，然后在词尾加-e，过去分词是在过去式的基础上再加-n,例如：,break-broke-brokenspeak-spoke-spokensteal-stole-stolenweave-wove-woven（编织,组合,编排）freeze-froze-frozenchoose-chose-chosenwake-woke-wokenawake-awoke-awoken,动词原形中有字母组合-ay的，过去式和过去分词改成-aid,例如：,say-said-saidpay-paid-paidlay-laid-laid,变动动词原形中的元音字母的,win-won-wondig-dug-dugstick-stuck-stuckhang-hung-hung(悬挂)hang-hanged-hanged(绞死)hold-held-heldsit-sat-satspit-spat-spatshine-shone-shone,另外还有一些都有相同的字母组合，变化相同的，因为例子较少，我们把它们列在一起，作为一组一组来记忆。,shake-shook-shakentake-took-takenmistake-mistook-mistakenwear-wore-wornbear-bore-borntear-tore-tornswear-swore-sworn（发誓,宣誓,咒骂）sell-sold-soldtell-told-told(例外的动词fear,hear等),overcome-overcame-overcomeget-got-gottenforget-forgot-forgottenundertake-undertook-undertaken,词性的互换,agree/approve/Legalpolite/practical/patientconvenience/dependent/complete/directunderstand/leadregular/responsible,变反义,believable/acceptable/lock/load/necessary/comfortable/popular/fairLikely/lucky/pleasantreasonable/friendly/happy/healthy/Easy/tidy/packFamiliar/aware/selfish/willing/sure/certain/fortunate/usual/common/wise/kind/fold,+y,difficult/honestdeliver/discover/recover,动词后加ment构成的名词,judge/achieve/adjust/agree/amaze/amuse/announce/appoint/arrange/astonish/develop/disappoint/embarrass/encourage/enjoyequip/excite/govern/improve/manage/punish/replace/require/retire/employ/move/settle/treataccomplish/advertise,以de结尾的动词改de为sion构成的名词,concludeexplodeinclude,变名词,exist/depend/persist,形容词后加ize构成的动词,summarizemodernizegeneralizespecializesymbolizeharmonize,加al的形容词,nature-naturalagriculture-agriculturalarchitecturearchitecturalglobe-globalCulture-culturalcondition-conditionalcentre-centralpractice-practicalofficeoffcialfinance-financialorigin-originaleducation-educationalenvironmentenvironmentaltraditiontraditionalcoast-coastal,以ic结尾的形容词,athlete-athletichero-heroichistory-historic(al),以able结尾的形容词,accept-acceptableavoid-avoidable-unavoidablefavourfavourable-unfavorablebear-bearable-unbearable,加ly构成的形容词,month-monthlyman-manlyfriend-friendlyLove-lovely,加ous构成的形容词,poison-poisonousfame-famouscourage-courageousdanger-dangerousmountain-mountainoushumour-humourousadventure-adventurous,加y构成的形容词,wealth-wealthysnow-snowystormstormythirst-thirstyhealth-healthyhunger-hungrywind-wind
