Don't和Doesn't的区别
使用上的区别
Don't
Don't是do not的缩写形式,它是一个缩略词,意思是“不要”。Don't是否定句的缩写形式,我们通常在句子的主语和谓语之间使用它。我们使用Don't来表达某件事情应该避免或不应该做。
例如:
We don't eat meat. (我们不吃肉)
Don't forget to do your homework. (别忘了做家庭作业)
Don't be late for the meeting. (别迟到开会)
另外,如果主语是第一人称单数,我们应该使用don't,而不是doesn't。例如:
I don't like coffee. (我不喜欢咖啡)
Doesn't
Doesn't是does not的缩写形式,同样也是一种否定表达方式,但与don't不同,我们通常使用doesn't来表达第三人称单数主语的否定情况。
例如:
She doesn't speak French. (她不说法语)
The car doesn't start. (轿车发动不了)
He doesn't like to watch TV. (他不喜欢看电视)
总结起来,Don't是一种缩写形式,用于否定句中,主要用于第一人称和第二人称,而Doesn't则主要用于第三人称单数主语的否定。
语法上的区别
Don't
在英语中,Don't是do not的缩写形式。在这种情况下,使用的情况取决于时态。我们可以在多个时态中使用Do或Don't:
- 现在进行时:am/is/are + not + Ving
例如:
I am not watching TV. (我不在看电视)
She is not studying for the exam. (她没有在为考试学习)
- 一般现在时:do/does + not + V
例如:
They do not like pizza. (他们不喜欢比萨)
He does not play soccer. (他不踢足球)
- 一般过去时:did not + V
例如:
I did not go to the concert. (我没去听音乐会)
They did not eat dinner together. (他们没有一起吃晚餐)
Doesn't
与Don't类似,Doesn't也取决于时态。但是,Doesn't仅用于第三人称单数:
- 现在进行时:is/are + not + Ving
例如:
He is not studying right now. (他现在没有在学习)
She is not drinking coffee. (她没有喝咖啡)
- 一般现在时:does not + V
例如:
She does not eat meat. (她不吃肉)
He does not like to swim. (他不喜欢游泳)
- 其他时态:did not + V
例如:
He did not come to the party. (他没有来参加派对)
She did not take the bus today. (她今天没有坐公交车)
总体而言,Don't和doesn't的用法和语法上的区别在于主语的人称和数。Don't适用于第一人称和第二人称,而Doesn't适用于第三人称单数主语。
