不規(guī)則英語動詞巧記法

  英語動詞按其過去式和過去分詞的構成方式可分為規(guī)則動詞和不規(guī)則動詞。規(guī)則動詞的過去式和過去分詞由詞尾加ed構成，而不規(guī)則動詞的變化因詞而異。但 如對不規(guī)則動詞的過去式和過去分詞做一分析，就可發(fā)現(xiàn)其中 的"規(guī)則"。為方便同學們記憶，現(xiàn)將初中英語教學大綱中的69 個不規(guī)則動詞的原形、過去式和過去分詞列出并規(guī)為五種類型。

  同學們還可將第二、三類分為若干組，以便準確記憶。

  一、AAA型（原形、過去式和過去分詞同形）：

  cost cost cost cut cut cut let let let put put put read read read

  二、ABB型（過去式與過去分詞同形）：

  bring brought brought build built built buy bought bought catch caught caught dig dug dug feel felt felt find 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 spent stand stood stood teach taught taught tell told told think thought thought understand understood understood

  三、ABC型（原形、過去式和過去分詞各異）：

  be was/were been begin began begun blow blew blown break broke broken do did done draw drew drawn drink drank drunk drive drove driven eat ate eaten fall fell fallen fly flew flown forget forgot forgotten give gave given go went gone grow grew grown know knew known lie lay lain ride rode ridden ring rang rung see saw seen show showed shown sing sang sung speak spoke spoken swim swam swum take took taken throw threw thrown wake woke woken wear wore worn write wrote written

  四、ABA型（原形與過去分詞同形）：

  become became become come came come

  五、AAB型 （原形與過去式同形）：

  注：帶※號的詞也可視為規(guī)則動詞。
