回答1:

1、对于大部分动词,原型动词 + ed 即可构成过去式。

例如:

want——wanted

watch——watched

water——watered

2、词尾是“e”:对于原型动词词尾有“e”的。直接 原型动词 + d 构成过去式。

例如:

love——loved

dance——danced

like——liked

3、词尾为“辅音+单个元音+辅音”:以一个辅音字母结尾的重读闭音节,构成过去式时要重复词尾辅音字母,然后 + ed构成过去式。

具体来说就是:辅音+单个元音+辅音 且该元音字母不发原来的音。

例如:

stop——stopped

plan——planned

4、词尾为“辅音+y”:原型词尾为“辅音+y”的动词,改“y”为“i”,+ ed构成过去式。

例如:

study——studied

carry——carried

cry——cried

5、不规则变化:有些动词过去式的变化规律不明显,只能通过背诵记忆。

例如:

is/am——was    

are——were    

do——did

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 – made get – 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

动词原形变过去式的规则

1、一般在动词原形末尾加ed。

2、以不发音的e结尾的动词,直接加d。

3、末尾只有一个辅音字母的重读闭音节词,先双写这个辅音字母,再加ed。

4、以“辅音字母➕y”结尾的动词,把y改为i,再加ed。
