don't can't的区别在哪里?特别在语句中
什么情况下用don't什么情况下用can't~如果可以的话有个列子谢谢~

don't 是动词的否定
can't 只是can的否定
don't可以放在句首,can't不行

don't do sth 是不做某事
can't do sth 是不能做某事
例:I don't go shopping on Sundays.我星期天不逛街。
I can't go shopping this Sunday.这个礼拜天我逛不成街。

don't单纯是助动词表示否定意思
can't是情态动词,“不能”、“不会”的意思
I don't drive.我不开车
I can't drive.
