Question

找一般过去时10句在改为否定句

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，动词慧尺桥还原，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。

特殊疑前猛问句也简单，疑问词加一般疑问句困正记心间。

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。
