一般过去时及动词的过去式变化规则

一般过去时

1、表示过去发生的动作或出现的状态,用动词的过去式来表达,如: I was at the library yesterday afternoon.

Tom studied hard and did well in the final exam last year. 2、动词的过去式分为规则动词和不规则动词两种: 规则动词的过去式:

一般情况下在动词原形后直接加ed. wantedplayed 以不发音的字母e结尾的动词,直接加-d hopedlived

重读闭音节单词如果末尾只有一个辅音字母需双写最后一个辅音字母, 再加-ed stopped

以辅音字母+y结尾的动词变yi,再加ed studiedworried 以元音字母+y结尾的动词,直接加ed played, enjoyed

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.

清辅音后,ed要读[t]workedfinished 元音或浊辅音后,ed要读 [d.livedcalled t]或[d]后,ed[id] startedneeded 不规则动词有其自己的变化形式,只能分别记忆。

9. winwon(赢得) 10.sleepslept 11 putput 12comecame

3)句式及其变化: a be动词过去式的句式:

否定句是在was/were后面加notwas not wasn’t)/were not weren't 一般疑问句是把was / were提前并放到句首,要求首字母要大写 b 实义动词过去式的句式:

①肯定式:主语+动词过去式+其它


:They had a good time yesterday

②否定式:主语+did notdidn’t)+动词原形+其它. 如:They didn't watch TV last night. ③一般疑问句:Did+主语+动词原形+其它
