不规则动词的过去式 (初二)

不规则动词的过去式是同学们学习的重点,也是一个难点。同学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,总结如下:
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:

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—
might,run—ran,see—saw, smell—smelt,take—took,wake—woke,
wear—wore
