动词过去式课件.ppt

* 1.什么是一般过去时？ 2.什么是动词过去式？ 一般过去时表示过去某个时间里发生的动作或状态； 在一般过去时态中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。 规则动词过去式的构成 ： 规则动词过去式：1.一般情况下，动词词尾加 ed 。 2.以不发音字母e结尾加d。 3.以辅音字母加y结尾变y为i加ed 过去式很简单， 前提必须是动词。 结尾有e只加d， live变成lived 以y结尾也不难， 把y变i加ed Cry变成cried， copy变成copied 目前双写只有俩，drop变成dropped, stop要变stopped。 其他动词很随和，带上ed成过去。 来看看口诀吧！ 过去式的读音： 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 不规则动词的过去式 不规则动词的过去式变化规律性不强，需多加记忆 go - went get - got buy - bought come - came see - saw do - did say - said eat - ate give - gave take- took 过去时的时间标志：yesterday（昨天）, last week（上周）, last month（上个月）, last year（去年）, two months ago（两个月前）, the day before yesterday（前天），in 1990 (在1990年), in those days （在那些日子里）等表示过去的时间状语。 如： 　　I was born in 1990. (我出生在1990年)。 　　When did you go to the park? （你是什么时候去的公园）。 　　I went to the park last week. （我是上周去的公园） 用法：动词过去式用在一般过去时态句子中。 　 　 saw see got get 　 　 said say flew fly wrote write ran run found find wore wear rode ride felt feel understood understand read read ate eat threw throw put put drove drive thought think met meet drank drink told tell made make drew draw taught teach lost lose did do took take left leave cut cut swam swim knew know came come stood stand heard hear caught catch spoke speak had have bought buy slept sleep grew grow brought bring sat sit went go began begin sang sing gave give was/were be 过去式 原形 过去式 原形 过去式 原形 小学阶段不规则动词过去式表 Goodbye! *
