牛津译林版英语7B Unit5课件：7B Unit 5 Grammar

一、什么情况下使用一般过去时? 1. We use the simple past tense to talk about things in the past.谈论在过去发生的事情或存在的状态

went是go在一般进去时中所用的 动词形式, 是go的过去式。A month ago, Millie and Amy went to Sunshine Park. 一个月前，米莉和艾米去了阳光公园。

Last Sunday, they went to the park again. 上个星期天, 她们又去了那儿。

2. We form the simple past tense by adding ‘-ed ’ to regular verbs. 提示：一般过去时常与表示过去的 时间状语连，如：yesterday, last night, a month ago, yesterday afternoon, last week, ten years ago in 1999, in 2008

二、规则动词过去式的构成方法12 3

绝大多数动词以e结尾的动词

+ed+d

walk— walked live—lived cry—cried stop— stopped

以辅音字母+y结 变y为ied 尾的动词 以一个元音字母 +一个辅音字母 结尾的短动词 双写末 尾的辅 音字母 +ed

4

提示: 以元音字母+y结尾的动词 按第一条规则，即：+ed, 如: stay —stayed

写出下列动词的过去式。want— wanted talk — talked like — liked worry — worried try — tried stop — stopped

三、不规则动词的过去式不是加ed

构成的, 需要我们记住它们。不规则动词的过去式归纳起来有这样几种 类型(见下表):

与原形一样, 没 1 有变化2 3 改变了元音 改变了辅音

cost-cost put-put write-wrote know-knew make-made spend-spent leave-left teach-taught

元音和辅音都变 4 化了

Infinitive am is are begin break bring build buy can

Past tense was were began broke brought built bought could

Infinitive catch come do draw drink drive eat fall

Past tense caught came did drew drank drove ate fell

四、谓语动词为实义动词的一般过 去时的句子结构 1) 肯定句 主语+谓语动词过去式…… He heard a whisper. They went to the park again last Sunday.

2) 否定句 主语 + didn’t +谓语动原形 …… I didn’t go to the park yesterday morning. He didn’t hear a whisper. They didn’t find anything in the bushes.

3)一般疑问句 Did +主语+谓语动原形……? Yes, 代词+did. / No, 代词+ didn’t. Did you go to the park yesterday morning? Yes, I did. Did he hear a whisper? No, he didn’t.
