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）：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 feltfind 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 spentstand 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 brokendo did done draw drew drawndrink drank drunk drive drove driveneat ate eaten fall fell fallenfly flew flown forget forgot forgotten give gave given go went gone grow grew grown know knew knownlie lay lain ride rode riddenring rang rung see saw seenshow showed shown sing sang sungspeak spoke spoken swim swam swumtake took taken throw threw thrownwake woke woken wear wore wornwrite wrote written四、ABA型（原形与过去分词同形）：become became becomecome came come 五、AAB型（原形与过去式同形）：beat beat beaten（注：带号的词也可视为规则动词。）
