  动词过去式和过去分词法则

  (一)、不规则动词过去式和过去分词

  动词的过去式和过去分词是初中英语教学中的重点,而有些动词的不规则变化是这些重点中的难点,但这些不规则变化也不是毫无规律可循的.现将初中英语中一些常用的不规则动词变化介绍如下.

  一、原形、过去式和过去分词的词形和读音都相同的单词,结尾字母一般是t或d.如:

  cut-cut-cut,hit-hit-hit,put-put-put,cost-cost-cost,let-let-let,shut-shut-shut,set-set-set,hurt-hurt-hurt,spread-spread-spread

  特殊:动词read的过去式和过去分词虽然词形与原形一致,read-read-read,但发音分别是[ri:d]-[red]-[red].

  二、有些动词的过去分词与原形是一样的.如:

  come-came-come,become-became-become,run-ran-run,overcome-overcame-overcome

  三、有些动词的过去式和过去分词相同.如:

  1.把单词结尾的字母d改为t.如:

  lend-lent-lent,spend-spent-spent,send-sent-sent

  2.改变单词中间元音字母.如:

  sit-sat-sat,win-won-won,shine-shone-shone,hold-held-held

  3.以eep结尾的动词,把eep改为ept.如:

  keep-kept-kept,sleep-slept-slept,sweep-swept-swept

  4.过去式和过去分词都以augh或ough结尾的动词.如:

  buy-bought-bought,fight-fought-fought,think-thought-thought,bring-brought-brought,teach-taught-taught,catch-caught-caught

  5.有的以ay结尾的动词,在过去式和过去分词中把ay变成aid.如:

  say-said-said,lay-laid-laid,pay-paid-paid

  6.另有一些其它形式的变化.如:

  have-had-had,learn-learnt-learnt,leave-left-left,lose-lost-lost,make-made-made,meet-met-met,feel-felt-felt

  四、有些动词原形中含有字母i,在过去式中变i为a,在过去分词中变i为u.如:

  五、以字母ow或aw结尾的动词,在变成过去式时,通常把元音字母变成e,在变成过去分词时,通常只在词尾加n.如:

  blow-blew-blown,draw-drew-drawn,grow-grew-grown,throw-threw-thrown,know-knew-known

  六、有些动词的过去分词是在原形词尾加n或en,变成以en结尾的单词.如:

  rise-rose-risen,give-gave-given,take-took-taken,fall-fell-fallen,drive-drove-driven,eat-ate-eaten

  特殊:write-wrote-written,speak-spoke-spoken,ride-rode-ridden,get-got-gotten

  (二)、动词过去式和过去分词的变化规则

  动词过去式和过去分词有规则变化和不规则变化两种.
