动词的过去分词变化规则：
1、一般在动词原形后加-ed 原形。
2、以-e结尾的动词直接加-d。
3、以辅音字母加y结尾的动词，变y为i， 再加-ed。
4、以元音字母加y结尾的词，直接加-ed。
5、末尾只有一个辅音字母的重读闭音节词，双写该辅音字母，再加-ed。

过去分词的变化规则：一般在动词原形后加ed；以e结尾的动词直接加d；以辅音字母加y结尾的词，直接加ed。
分规则变化和不规则变化两种。不规则变化需逐个记忆，规则变化遵循以下原则：
(1)一般情况下，在动词后加ed构成：work/worked,stay/stayed,shout/shouted等。
(2)在以-e结尾动词后只加d：close/closed,like/liked,live/lived,smile/smiled等。
(3)以辅音字母加y结尾的动词，应将y改为i再加-ed：study/studied,carry/carried等。
(4)以重读闭音节或r音节结尾且末尾只有一个辅音字母动词，要双写末尾的辅音字母再加-ed：stop/stopped,admit/admitted,refer/referred,prefer/preferred等。
【注】(1)以字母l结尾的动词，若末尾一个音节为重读音节，则必须双写l再加-ed，如control/controlled，但若末尾一个音节为非重读音节，则可双写l(英国英语)或不双写l(美国英语)，如travel/travel(l)ed。
(2)动词picnic(野餐)的过去式和过去分词是picnicked，不是picniced。
(3)词尾-ed读音规则是：在清辅音后读作[t]，元音和浊辅音后读作[d]，在辅音[t]或[d]后读作[id]。
双写加ed的动词过去式是英语动词过去式的一种变化规则。
双写加ed的动词过去式有以下情况：
一、以重读闭音节结尾且末尾只有一个辅音字母，双写最后的辅音字母+ed。
例如：patted（拍打，轻敲）, quitted（放弃，停止），stopped（停止）, begged（乞讨，乞求）, spotted（发现），planned（计划）等。这些都是单音节的词，单音节的词要重读，而且都是”一个元音+一个辅音“，都属于重读闭音节词，所以都双写尾字母+ed。
二、两个音节的词第二个音节重读，而且第二个音节都是”一个元音+一个辅音“，所以第二个音节属于重读闭音节，因此这些词都双写尾字母+ed。
例如： referred（参考），regretted（后悔，遗憾），admitted (承认，允许)，permitted(许可，允许)等。
双写加ed的动词过去式常见的词有：
admit --- admitted
beg ---- begged
drip ---- dripped
dot ---- dotted
drop ---- dropped
一、定义不同
动词的过去式是一个动词，单独作谓语。不能与助动词、情态动词连用。它的词性与动词的第三人称单数一样。 动词的过去式可分为规则动词和不规则动词。
规则动词的过去式变化如下：
1、一般情况下，动词词尾加 -ed ，如：worked played wanted acted
2、以不发音的 -e 结尾动词，动词词尾加 -d，如：lived moved decided declined hoped judged raised wiped
3、以辅音字母 + y结尾的动词，把-y变为-i 再加-ed，如：studied tried copied justified cried carried embodied emptied
4、以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed，如：stopped begged fretted dragged dropped planned dotted dripped
5、不规则动词的过去式变化规律性不强，须多加记忆。
go - went，make - made， get - got ，buy - bought ，come - came ，fly-flew ，is/am-was， are-were ，see-saw ，bring-brought，do-did，teach-taught, think-thought, are-were, say-said,sit-sat. 动词过去分词与动词过去式的区别是词性不同、用法不同、应用场合不同。
1、词性不同：动词的过去式是一个动词，单独作谓语；动词的过去分词是动词的一种非谓语形式，也叫非限定性动词。
例句：
（1）The library is now closed. 图书馆关门了。(过去分词作表语)
（2）I had a word with Julia this morning.今天早晨，我跟朱莉娅说了几句话。（过去式表示过去习惯性、经常性的动作）

不规则动词过去式和过去分词巧记方法
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
动词的过去分词变化规则：
1、一般在动词原形后加-ed 原形。
2、以-e结尾的动词直接加-d。
3、以辅音字母加y结尾的动词，变y为i， 再加-ed。
4、以元音字母加y结尾的词，直接加-ed。
5、末尾只有一个辅音字母的重读闭音节词，双写该辅音字母，再加-ed。
扩展资料
过去分词的变化规则：一般在动词原形后加ed；以e结尾的动词直接加d；以辅音字母加y结尾的词，直接加ed。
分规则变化和不规则变化两种。不规则变化需逐个记忆，规则变化遵循以下原则：
(1)一般情况下，在动词后加ed构成：work/worked,stay/stayed,shout/shouted等。
(2)在以-e结尾动词后只加d：close/closed,like/liked,live/lived,smile/smiled等。
(3)以辅音字母加y结尾的动词，应将y改为i再加-ed：study/studied,carry/carried等。
(4)以重读闭音节或r音节结尾且末尾只有一个辅音字母动词，要双写末尾的辅音字母再加-ed：stop/stopped,admit/admitted,refer/referred,prefer/preferred等。
【注】(1)以字母l结尾的动词，若末尾一个音节为重读音节，则必须双写l再加-ed，如control/controlled，但若末尾一个音节为非重读音节，则可双写l(英国英语)或不双写l(美国英语)，如travel/travel(l)ed。
(2)动词picnic(野餐)的过去式和过去分词是picnicked，不是picniced。
(3)词尾-ed读音规则是：在清辅音后读作[t]，元音和浊辅音后读作[d]，在辅音[t]或[d]后读作[id]。
双写加ed的动词过去式是英语动词过去式的一种变化规则。
双写加ed的动词过去式有以下情况：
一、以重读闭音节结尾且末尾只有一个辅音字母，双写最后的辅音字母+ed。
例如：patted（拍打，轻敲）, quitted（放弃，停止），stopped（停止）, begged（乞讨，乞求）, spotted（发现），planned（计划）等。这些都是单音节的词，单音节的词要重读，而且都是”一个元音+一个辅音“，都属于重读闭音节词，所以都双写尾字母+ed。
二、两个音节的词第二个音节重读，而且第二个音节都是”一个元音+一个辅音“，所以第二个音节属于重读闭音节，因此这些词都双写尾字母+ed。
例如： referred（参考），regretted（后悔，遗憾），admitted (承认，允许)，permitted(许可，允许)等。
双写加ed的动词过去式常见的词有：
admit --- admitted
beg ---- begged
drip ---- dripped
dot ---- dotted
drop ---- dropped
一、定义不同
动词的过去式是一个动词，单独作谓语。不能与助动词、情态动词连用。它的词性与动词的第三人称单数一样。 动词的过去式可分为规则动词和不规则动词。
规则动词的过去式变化如下：
1、一般情况下，动词词尾加 -ed ，如：worked played wanted acted
2、以不发音的 -e 结尾动词，动词词尾加 -d，如：lived moved decided declined hoped judged raised wiped
3、以辅音字母 + y结尾的动词，把-y变为-i 再加-ed，如：studied tried copied justified cried carried embodied emptied
4、以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed，如：stopped begged fretted dragged dropped planned dotted dripped
5、不规则动词的过去式变化规律性不强，须多加记忆。
go - went，make - made， get - got ，buy - bought ，come - came ，fly-flew ，is/am-was， are-were ，see-saw ，bring-brought，do-did，teach-taught, think-thought, are-were, say-said,sit-sat. 动词过去分词与动词过去式的区别是词性不同、用法不同、应用场合不同。
1、词性不同：动词的过去式是一个动词，单独作谓语；动词的过去分词是动词的一种非谓语形式，也叫非限定性动词。
例句：
（1）The library is now closed. 图书馆关门了。(过去分词作表语)
（2）I had a word with Julia this morning.今天早晨，我跟朱莉娅说了几句话。（过去式表示过去习惯性、经常性的动作）

不规则动词过去式和过去分词巧记方法
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
