亲爱的同学怎么说英语

"Dear classmate" is a formal way to address a classmate in Engpsh. "Dear" is a term of endearment that is often used to start a letter or email to someone you know or are close to. "Classmate" refers to someone who is a member of the same class or group as you.

Here's an example of how you could use this phrase in a sentence:

"Dear classmate, I hope this email finds you well. I was wondering if you could help me with the assignment that is due tomorrow."

Alternatively, you could simply say "Hi" or "Hello" followed by your classmate's name if you want a more casual greeting.
