1、表示一般过去式的动词通常用动词的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的。

2、动词的过去式可分为规则动词和不规则动词。

3、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: worked played wanted acted (2)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 (3)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 (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: stopped begged fretted dragged dropped planned dotted dripped (5)注:不规则动词的过去式变化规律性不强,须多加记忆。

4、 go - went, make - made, get - got , buy - bought ,come - came , fly-flew , is/am-was,are-were , see-saw , bring-brought, do-did, teach-taught, think-thought, say-said, sit-sat. read-read, spend-spent, eat-ate, give-gave, sit-sat, tell-told, write-wrote, fell-felt, find-found, hear-heard, know-knew, put-put, grow-grew, take-took, catch-caught, come-came, become-became, swim-swam, sweep—swept, sing—sang,draw—drew,。
