怎么改英语陈述句为否定句?

如题所述

原句:I dropped my icecream.(我的冰淇淋掉了。)

改为否定句:I didn't drop my icecream.(我的冰淇淋没有掉)


【英语陈述句改为否定句的方法】

一、如果句子的谓语本身含有be动词,直接在be后加not即可。

例如:

1、

She is goot at science.(她擅长科学。)

➣➣➣She is not(isn't) good at science.(她不擅长科学。)

2、

She is reading a book.(她正在看书。)

➣➣➣She isn't reading a book.(她没有在看书。)

二、如果句子的谓语含有助动词have(用于完成时。注意是助动词,不是实意动词),直接在have后面加not即可。

例如:

1、

She has read this book.(她读过这本书。)

➣➣➣She has not(hasn't) read this book.(她没有读过这本书。)

2、

She had finished the housework when I came back home.(当我回到家时,她已经做完家务了。)

➣➣➣She hadn't finished the housework when i came back home.(当我回到家时,她还没有做完家务。)

三、当句子含有情态动词时(can, could,must, should, shall, will, would, may,might等),直接在情态动词后加not。

例如:

You can do it tomorrow.(你可以明天再做。)

➣➣➣You can't do it tomorrow.(你不可以明天再做。)

※但需注意,情态动词must表示必须做某事的时候,其否定不用mustn't(mustn't表示一定不能,而不是“不必”,而应该用needn't)。

例如:

Must i finish the task today?(我必须今天完成任务吗?)

——No, you needn't.(不,不必今天。)
