过去
规则动词的过去式变化如下:

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。
