不規則動詞過去式和過去分詞巧記方法
一、原形、過去式和過去分詞的詞形和讀音都相同的單詞，結尾字母一般是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：動詞read的過去式和過去分詞雖然詞形與原形一致，read-read-read，但發音分別是[ri:d]-[red]-[red]。
二、有些動詞的過去分詞與原形是一樣的。如：
come-came-come,become-became-become,run-ran-run,overcome-overcame-overcome
三、有些動詞的過去式和過去分詞相同。如：
1.把單詞結尾的字母d改為t。如：
lend-lent-lent,spend-spent-spent,send-sent-sent
2.改變單詞中間母音字母。如：
sit-sat-sat,win-won-won,shine-shone-shone,hold-held-held
3.以eep結尾的動詞，把eep改為ept。如：
keep-kept-kept,sleep-slept-slept,sweep-swept-swept
4.過去式和過去分詞都以augh或ough結尾的動詞。如：
buy-bought-bought,fight-fought-fought,think-thought-thought,bring-brought-brought,teach-taught-taught,catch-caught-caught
5.有的以ay結尾的動詞，在過去式和過去分詞中把ay變成aid。如：
say-said-said,lay-laid-laid,pay-paid-paid
6.另有一些其它形式的變化。如：
have-had-had,learn-learnt-learnt,leave-left-left,lose-lost-lost,make-made-made,meet-met-met,feel-felt-felt
四、有些動詞原形中含有字母i，在過去式中變i為a，在過去分詞中變i為u。如：
begin-began-begun,sing-sang-sung
五、以字母ow或aw結尾的動詞，在變成過去式時，通常把母音字母變成e，在變成過去分詞時，通常只在詞尾加n。如：
blow-blew-blown,draw-drew-drawn,grow-grew-grown,throw-threw-thrown,know-knew-known
六、有些動詞的過去分詞是在原形詞尾加n或en，變成以en結尾的單詞。如：
rise-rose-risen,arise-arose-arisen，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
