一般过去时否定句句型结构?

59

一般过去时否定句的句型结构主要有两种形式,需根据主语的人称和数进行选择:

一、实义动词的否定句

结构: 主语 + did not / didn't + 动词原形 + 其他

例如:

I did not (didn't) finish my homework yesterday.

He didn't call you last night.

注意事项

1. 动词需使用原形,无需加 -ed(如played→play);

2. 若主语为第一人称、第二人称或复数,均使用 did not,第三人称单数使用 didn't

二、系动词(be动词)的否定句

结构: 主语 + was/were + not + 表语

例如:

She was not (didn't) at home last weekend.

They were not (didn't) ready on time.

注意事项

需根据主语选择be动词的过去式:

I/you/they → was/were

he/she/it → was

we/they → were 。

三、综合示例

实义动词:Tom didn't eat breakfast this morning.

系动词:The meeting was not (didn't) scheduled for today.

四、易混淆点

动词原形后无需加 -s或 -es,例如 didn't run而非 didn't runs

若主语为第三人称单数(如he/she/it),be动词用 was,实义动词仍用原形(如 didn't eat)。

通过以上结构,可灵活构建一般过去时的否定句,需根据语境选择合适类型。
