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:work ---worked play---played wanted----wanted act----acted
2、以不发音的 -e 结尾动词,动词词尾加 -d,如: live---livedmove----moved taste---tasted hope---hoped
3、以辅音字母 + y结尾的动词,把-y变为-i 再加-ed,如: study---studiedcopy---copied cry---cried carry---carried
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:stop ---stopped
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 – madeget – got buy - bought come - came fly-flew

不规则动词的过去式的构成
1.把动词原形中的i改为a,变成过去式。如:
begin—began,drink—drank,give—gave,ring—rang,sing—sang,sit—sat,swim—swam
2.把重读开音节中的i改为o,变成过去式。如: drive—drove,ride—rode,write—wrote
3.改动词原形中的aw /ow为ew,变成过去式。如:
draw—drew,grow—grew,know—knew,throw—threw(动词show除外,show—showed)
4.动词原形中的e改为o,变成过去式。如: get—got,forget—forgot
5.动词原形中的ee改为e,变成过去式。如: feed—fed,meet—met
6.动词原形中的eep改为ept,变成过去式。如: keep—kept,sleep—slept,sweep—swept
7.动词原形中的eak改为oke,变成过去式。如: break—broke,speak—spoke
8.动词原形中的ell改为old,变成过去式。如: sell—sold,tell—told
9.动词原形中的an改为oo,变成过去式。如: stand—stood,understand—understood
10.以ought和aught结尾,且读音是〔 :t〕的过去式。如:
bring—brought,buy— bought,think—thought,catch—caught,teach—taught
11.以ould结尾且读音为〔ud〕的情态动词过去式。如: can—could,shall—should,will—would
12.把动词原形中的o改为a,变成过去式。如: come—came,become—became
13.在动词原形后加d或t变成过去式,并且发生音变。如:
hear〔hi 〕—heard〔h :d〕, say〔sei〕—said〔sed〕,mean〔mi:n〕—meant〔ment〕
14.动词的过去式与动词原形一样。如: let—let,must—must,put—put,read—read〔red〕
15.不符合上述规律的动词过去式。如:
am,is—was,are—were,build—built,do—did,eat—ate,fall—fell,feel—felt,find—found,fly—flew,go—went,have /has— had,hold—held,leave—left,make—made,may—might,run—ran,see—saw,take—took
过去式“-ed”的发音规则
(1)动词词尾为“t,d”时,发/ id /音, want →wanted (要)need →needed (需要)
(2)动词词尾为清辅音时,发/ t / 音。
help →helped (帮助)laugh →laughed (笑)look →looked (看)
kiss →kissed (吻)wash →washed (洗) watch →watched (注视)
(3)动词词尾为t,d以外之浊辅音或元音时,发/ d /音。
call →called (叫)stay→stayed (停留)cry→cried (哭)动词过去式变化规则
一、规则变化
1、 一般情况下,动词词尾加-ed, 如:work—worked play—played want—wanted ask—asked
2、 以不发音的-e结尾动词,动词词尾加-d, 如:live—lived move—movedtaste—tasted
3、 以“辅音字母+y”结尾的动词,把y改成i, 加—ed, 如:study—studies try—tried copy—copied carry—carried
4、 重读闭音节动词,双写词尾辅音字母,再加—ed, 如:stop—stopped
二、不规则变化
is am—was are—were do—did have has—had go—went meet—met come—came take—tooksteal—stole eat—ate fly—fliew run—ran see—saw say—said make—made find—foundstand—stood
sit—sat sing—sang drink—drank give—gave ring—rang swim—swam
write—wrote ride—rode drive—drove
draw—drew grow—grew know—knew
get—got forget—forgot
sweep—swept keep—kept sleep—slept
speak—spoke break—broke
tell—told sell—sold
buy—bought think—thought catch—caught teach—taught build—built
can—could shall—should will—would
过去式与动词原形一样:let—letmust—must put—put read—read

三、动词过去式构成读音
1、 清辅音后读清辅音[t] (清读清)如:jump like
2、 浊辅音后读浊辅音[d] (浊读浊)如:listen pull
3、 元音后面读浊辅音[d] (元音后面读浊音)如:water play
4、 [t][d]后面读[id] want need

不规则动词的一些变化规则
  不规则动词的变化规则作了归纳整理,分为以下几类,便于同学们更好地记忆。
1. 三种动词形式变化(即原形,过去式,过去分词)一致的
cast---cast---cast
cost---cost---cost
