将英语祈使句变为否定句,主要有以下几种方法:
在祈使句前加Don't或Do not
例如:
Don't close the door. (别关上门。)
Do not sit down. (不要坐下。)
Don't talk. (别说话。)
在动词原形前加Don't或Do not
例如:
Close the door, don't close the door. (关上门,别关上门。)
Sit down, do not sit down. (坐下,不要坐下。)
Talk, don't talk. (说话,别说话。)
对于以Let's开头的祈使句,在Let's后加not
例如:
Let's talk about it. — Let's not talk about it. (我们别谈论它吧。)
Let's go swimming there. — Let's not go swimming there. (我们别去那里游泳吧。)
对于无动词的祈使句,在句首加not
例如:
Here? — Not here. (不是这里。)
Green? — Not green. (不是绿色的。)
This one? — Not this one. (不是这个。)
在公共场合的提示语中,常用“No+名词/现在分词”结构表示“禁止做某事”
例如:
No smoking. (禁止吸烟。)
No parking. (禁止停车。)
通过以上方法,你可以轻松地将祈使句变为否定句。希望这些规则对你有所帮助!
