写给老师的问候信应该怎么写？IN ENGLISH ，

为什么一定要用英文呢,你的老师是英语老师吗?
我建议你还是用中文吧,给老师写信是问候,书面问候对于一个中国人来说,中文是最美丽的语言,而且也是你最擅长最能掌控好的语言.但如果你的老师是外国人那就另当别论了.
我在毕业前也给我们英语老师写过信,当时是没有他电话号码,想约他出来聚餐,后来我也没用英文给他写信,用中文给他写的,他收到很高兴.
但是如果楼主能够获得一封满意的英文信件范例,这也不失为一种能够让你们老师惊喜的方式.

Dear Mr.***(不要用teacher）：

How are you getting on with your study there？

It was really a pleasant surprise to bump into(想简单点就用meet取代bump into）you in July（月份你自己改一改）。All my classmates miss you very much, and we long to see you back and teach us again!

Teacher's Day is coming. I send you my best wishes for the future and hope you will take good care of yourself.

Best regards.

Sincerely yours,
***

希望符合你的要求.用纤细秀气的字体写在一张贺卡上挺合适的。

回答要真挚 我觉得语言朴素最好 不要太过花哨 写给老师的 老师会觉得朴素的语言最质朴
