1. 把动词原形中的o改为a，变成过去式。过去分词不变．如：
become—became, come—came
2．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 ，sink—sank，
3．把重读开音节中的i改为o，变成过去式。如：
drive—drove，ride—rode，shine—shone，win—won，write—wrote
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eep改为ept，变成过去式。如：
keep—kept，sleep—slept，sweep—swept
6. 动词原形中的an改为oo，变成过去式。如：
stand—stood，understand—understood
7．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）
8．动词原形中的eak改为oke，变成过去式。如：
break—broke，speak—spoke
9．动词原形中的ell改为old，变成过去式。如：
sell—sold，tell—told
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．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〕， dream—dreamt 〔dremt〕
13．动词的过去式与动词原形一样。如：
cut—cut, hit—hit, hurt—hurt, let—let，must—must，
put—put，read—read〔red〕，set—set
14. 动词的过去式有两种形式。如：
dream—dreamed/ dreamt learn—learnt/ learned shine—shone/ shined
smell—smelt/ smelled wake—woke/ waked
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，hide—hid，
hold—held，lay—laid，leave—left，lie—lay，lose—lost，make—made，may—
