sure除了当然的意思以外还有很多意思,而of course只有当然的意思,如果在句子中只强调当然的意思,就可以用of course。在语法上区别不大。
of course 一般都是单独用,后边要加个逗号之类的
sure可以用在句子里面
另外sure有些时候是确定的意思,是形容词. of course 不能当形容词用
sur是可以啊 确定的意思 of course是当然啊的意思
sure 是很爽块地回答可以,一定,无疑的.
of course 是理所当然的意思.
两者很多情况下能混用.
举例,必须用sure的时候:
He is clever, to be sure, but not very hard-working.
She is sure to pass the examination.
必须用 of course的时候:
Mothers as a matter of course have much affection for their children.
I will write to you of course, but not every week.
