不规则动词过去式和过去分词巧记方法
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：
begin-began-begun,sing-sang-sung
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, 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
