动词过去式的变化形式
规则变化：
1. 一般在动词原形后面加ed.如：walk- walked,play-played,jump-jumped,…
2. 以不发音e结尾的动词,直接在末尾加d.如：skate-skated,like-liked…
3. 以一个元音字母加一个辅音字母结尾的重读闭音节动词,先双写结尾的辅音字母,再加ed.此条件不好掌握,可以这样记：先判定是重读闭音节结尾,末尾是“辅音字母+元音字母（读旁音,即读除了字母表之外的音.）+辅音字母”时,双写末尾辅音字母加ed.如shop-shopped,…
不规则变化的有：had, said, got, did, hit, found, ran, lay, brought, shone, knew, grew, went, saw, ate, thought, bought, taught, fell, broke, hurt, lost ,won, was, were.
常见的有下面几个：go-went, eat-ate, see-saw, buy-bought, teach-taught, think-thought, fall-fell, break-broke, hurt-hurt, is, am-was, are-were.用下面这一段话来记：昨天,我去饭店吃饭,看到Danny,给他买了球,教他玩,他认为他会,可是他摔倒了,摔断了尾巴,他的尾巴受伤了,他很可怜,是不是?
二、规则动词词尾加-ed有三种读音：
1. 在清辅音后读作[t].如：asked, helped, watched, stopped
2. 在浊辅音和元音后读作[d].如：enjoyed, studied, moved, called
3. 在t / d后读作[id].如：wanted, needed
