八年级英语上册英语动词词形变化英语动词按其过去式和过去分词的构成方式可分为规则动词和不规则动词。规则动词的过去式和过去分词由词尾加ed构成，而不规则动词的变化因词而异。但如对不规则动词的过去式和过去分词做一分析，就可发现其中的“规则”。为方便同学们记忆，现将初中英语教学大纲中的69个不规则动词的原形、过去式和过去分词列出并规为五种类型。同学们还可将第二、三类分为若干组，以便准确记忆。一、AAA型（原形、过去式和过去分词同形）：costcostcostcutcutcutletletletputputputreadreadread二、ABB型（过去式与过去分词同形）：bringbroughtbroughtbuildbuiltbuiltbuyboughtboughtcatchcaughtcaughtdigdugdugfeelfeltfeltfindfoundfoundgetgotgothavehadhadhearheardheardholdheldheldkeepkeptkept※learnlearntlearntleaveleftleftlendlentlentmakemademademeetmetmetpaypaidpaidsaysaidsaidsellsoldsoldsendsentsentshineshoneshonesitsatsatsleepsleptslept※smellsmeltsmeltspendspentspentstandstoodstoodteachtaughttaughttelltoldtoldthinkthoughtthoughtunderstandunderstoodunderstood三、ABC型（原形、过去式和过去分词各异）：bewas/werebeenbeginbeganbegunblowblewblownbreakbrokebrokendodiddonedrawdrewdrawndrinkdrankdrunkdrivedrovedriveneatateeatenfallfellfallenflyflewflownforgetforgotforgottengivegavegivengowentgonegrowgrewgrownknowknewknownlielaylainrideroderiddenringrangrungseesawseenshowshowedshownsingsangsungspeakspokespokenswimswamswumtaketooktakenthrowthrewthrownwakewokewokenwearworewornwritewrotewritten四、ABA型（原形与过去分词同形）：becomebecamebecomecomecamecome五、AAB型（原形与过去式同形）：beatbeatbeaten（注：带※号的词也可视为规则动词。）
