shouldn't和can't有什么区别??

作者&投稿:富侧 (若有异议请与网页底部的电邮联系)
Can't 、mustn't 、shouldn't 的区别?(急)~

can't 不可能,不太可能(表示推测某事发生的可能性非常低)

mustn't是指不准,不许
例句:you mustn't tell Jerry what I have bought不准你告诉杰瑞我买了什么,不能用于推测

shoudn't是指不该,不应该..(认为做某事不对)
you shoudn't come here
你不应该来这

He can't be here,I didn't see him
表示推测他在这的可能性还小,所以用can't

shouldn't表示不应该,语气较委婉
mustn't表示禁止,语气较强
may 1.表示允许或征求对方许可 2.表示可能性
shall表示建议,可以
shan't表示建议不要
can表示能,可以,会,语气比shall稍强
could表示可以,能够,比较委婉
must表示命令,必须,肯定,语气较强

您好
shouldn't 意思是不应该(不该做而做了)
can't意思是不可能(表示否定推测)
欢迎追问~
