1.动词过去式的写法

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 broughtbuild built built buy bought boughtcatch caught caught dig dug dugfeel felt felt find found foundget got got have had hadhear heard heard hold held heldkeep kept kept ※learn learnt learntleave left left lend lent lentmake made made meet met metpay paid paid say said saidsell sold sold send sent sentshine shone shone sit sat satsleep slept slept ※smell smelt smeltspend spent spent stand stood stoodteach taught taught tell told toldthink thought thought understand understoodunderstood三、ABC型（原形、过去式和过去分词各异）：be waswere beenbegin began begun blow blew blownbreak broke brokendo did donedraw drew drawndrink drank drunkdrive drove driveneat ate eatenfall fell fallenfly flew flownforget forgot forgottengive gave givengo went gonegrow grew grownknow knew knownlie lay lainride rode riddenring rang rungsee saw seenshow showed shownsing sang sungspeak spoke spokenswim swam swumtake took takenthrow threw thrownwake woke wokenwear wore wornwrite wrote written四、ABA型（原形与过去分词同形）：become became becomecome came come 五、AAB型（原形与过去式同形）：beat beat beaten。
