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---lived
move----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---studied
copy---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
