一、规则变化:
1. 动词原形后直接加ed
如:want——wanted,play——played,help——helped
2. 以”e“结尾的动词后直接加d
3. 如:dance——danced,love——loved,live——lived
4. 词尾为”辅音+单个元音+辅音“结构 , 双写最后一个字母 , 再加ed
如:stop——stopped,travel——travelled,plan——planned
5. 词尾为”辅音+y“结构 , 将y变为i加ed
如:carry——carried,cry——cried,study——studied
二、不规则变化
有些动词过去式的变化规律不明显 , 只能通过背诵记忆
如:go——went,have/has——had,tell——told,catch——caught
3.英语动词过去式的写法(要全)①一般情况下在动词原形后直接加-ed 。
如:wanted,played 。②以不发音的字母e结尾的动词 , 去掉e再加-ed 。
如:hoped,lived 。③重读闭音节单词需双写最后一个辅音字母再加-ed 。
如:stopped 。④以辅音字母+y结尾的动词变y为i , 再加-ed 。
如:studied,worried 。规则动词过去式的读音也有规律可循 。
请记住:清后[t] , 元浊[d],[t] [d]之后读[Id] 。①清辅音[p] [k] [f] [s] [F] [tF]等后 , ed要读[t] 。
如:worked,finished 。②元音或浊辅音[b] [g] [v] [z] [m]等后 , ed要读[d] 。
如:lived,called 。③[t]或[d]后 , ed读[Id] 。
如:started,needed 。b.不规则动词变化 be动词过去式有两种形式 , 主语是第一、三人称单数形式使用was , 其他人称用were 其他的大概有几类 一、AAA型(原形、过去式和过去分词同形): cost cost cost cut cut cut let let let put put put read read read 二、ABB型(过去式与过去分词同形): bring brought brought build built built buy bought bought catch caught caught dig dug dug feel felt felt find found found get got got have had had hear heard heard hold held held keep kept kept ※learn learnt learnt leave left left lend lent lent make made made meet met met pay paid paid say said said sell sold sold send sent sent shine shone shone sit sat sat sleep slept slept ※smell smelt smelt spend缉肌光可叱玖癸雪含磨 spent spent stand stood stood teach taught taught tell told told think thought thought understand understood understood 三、ABC型(原形、过去式和过去分词各异): be was?were been begin began begun blow blew blown break broke broken do did done draw drew drawn drink drank drunk drive drove driven eat ate eaten fall fell fallen fly flew flown forget forgot forgotten give gave given go went gone grow grew grown know knew known lie lay lain ride rode ridden ring rang rung see saw seen show showed shown sing sang sung speak spoke spoken swim swam swum take took taken throw threw thrown wake woke woken wear wore worn write wrote written 四、ABA型(原形与过去分词同形): become became become come came come 五、AAB型(原形与过去式同形): beat beat beaten 。
4.英语的动词过去式是啥表示过去某个时间里发生的动作或状态 。
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 。动词的过去式可分为规则动词和不规则动词 。
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 。go – went make – made get – got buy - bought come - came fly-flew 不规则动词的过去式的构成 1.把动词原形中的i改为a , 变成过去式 。
