一般过去时的否定句怎么变

Question

如题所述

Answer 1

一般过去时的否定形式：主语+didn't +谓语动词原形+其他。

1、was/were+not。

2、在行为动词前加didn't，同时还原行为动词。

例句：I didn't know you like coffee.——我不知道你喜欢咖啡。

肯定句变为否定句：

1、当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。

例如：I could get you a concert ticket. → I could not / couldn't get you a concert ticket.

2、当句中含有系动词was，were 时，可直接在其后加not构成否定句。

例如：I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.

3、当句中谓语是除情态动词、助动词、系动词was,were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句。

例如：The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

记忆口诀

一般过去时并不难，过去动作、状态记心间。

动词要用过去式，时间状语句末站。

否定句很简单，didn't 站在动原前，其它部分不要变。

一般疑问句也好变，did放在句子前，主语、动原、其它部分依次站立。

特殊疑问句也简单，疑问词加一般疑问句记心间。

一般过去时表示过去某个时间或某一段时间内发生的动作或存在的状态，常和过去的时间状语连用。

Answer 2

一般都是把过去时变成动词原形，然后在前面加上didn't
例如
He went to the park last Sunday
变成
He didn't go to the park last Sunday

Answer 3

看谓语动词是什么 。如果是was were 那么直接在was were 后加not
如果是行为动词的过去式，那么在行为动词前加didn't ，再把行为动词变成原形。例如I went shopping yesterday. 否定I didn't go shopping yesterday.

Answer 4

1.如果句中没有be动词，就在人称后面加did not，过去式变原型。2.如果有be动词，再be动词后加not，过去式不用变原型。

Answer 5

be动词：肯定句：He was a student.否定句：He was not a student.
肯定句：they were students. 否定句：they were not students.
一般动词：肯定句：He studied hard.否定句：He did not study hard.
