二、这里需要注意的是：不规则动词的过去式是同学们学习的重点，也是一个难点。我们应通过不规则动词的动词原形和它们的过去式找出其变化规律，比如：
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
