急！英语方面的问题

明白你的意思了。。。
其实不规则的你见多了就掌握规律了，简单说有一些小小规律：
1、o变成a，比方说come变came，become变became
2、d变成t，send变sent，build变built
3、-eep变-ept，sleep变slept，keep变kept
4、an变oo，understand变understood，stand变stood
我依靠自己的经验想出来了这些，多了得靠自己总结，但是背下面这个是正道儿。。。
规则动词的过去式变化如下：
一般情况下，动词词尾加 -ed ，如：
worked played wanted acted
以不发音的 -e 结尾动词，动词词尾加 -d，如： lived moved decided declined hoped judged raised wiped
以辅音字母 + y结尾的动词，把-y变为-i 再加-ed，如：
studied tried copied justified cried carried embodied emptied 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： stopped begged fretted dragged dropped planned dotted dripped 注：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
