”录取通知书”这一词用英语怎么写？

admission notice letter

admission notice的确可以,表示入取通知,但如果强调'书'(也就是收到的信件),最好加上LETTER

如: Tom received his admission notice letter yesterday.

offer 一般用在'工作'上,

另:也可以直接说Admission letter

Admission Notice就行。

admission offer letter

enroll recruit admot notice advice note
一般情况下，Notice of enroll就可以了，不过还可以用recruit advice note
