7. Clear and concise is best. Your prof might get 25 or 30 E-mails a day, so, it's best if you ask your questions in as focused and succinct a way as possible. (Hint: it's often good to number your questions). And, if your question is very elaborate or multifaceted, it's best to go to an in-person office hour. You'll get better service that way.

清楚简洁是最好的。你的教授每天会收到25-30封邮件，所以如果你的问题很简洁明了那是最好的(一般把问题一条条列出来比较好)。如果你的问题表述的很详尽或者多层面的，最好在教授的办公时间面谈，这样教授就能够更有效地帮你解决问题。

8. Always acknowledge. If your professor deigns to answer—or send you the handout or reference that you asked for—be sure to tell him or her that you got it. That way he or she will think kindly of you next time they see you in class.

必须要告知教授已收到邮件。如果你的教授给你回答或者发送了你需要的资料，一定要告诉他你已经收到了。这样，下次在课堂上看到你的时候，他们就会觉得你是个不错的学生。

9. THIS IS NOT A SHOUTING MATCH. Don't write in all uppercase letters, which is an E-mail convention for anger or other strong emotions. No one likes yelling.

这不是大声嚷嚷的争吵。邮件不要都用大写字母来写，因为这是一种在邮件中表达愤怒或者其他强烈的感情的方式。没有人喜欢喊叫的。

10. No one really likes emoticons and smileys. Trust us on this one. :)

没有人真的喜欢表情符号和微笑符。请相信这一点。

11. This is not Facebook. Don't write the professor in the way you'd write on your friend's wall.

这不是Facebook。你写给教授的邮件不要像你在朋友留言板上的留言一样。重要提示：千万不要和你的教授开玩笑，这个时候，无论多可笑都不可以。

12. This is not IM-ing. So pls dun wrte yor profeSR lIk ur txtN. uz abbrz @ yor own rsk. coRec me f Im wrng.

这不是写即时消息....所以不要像写短消息一样用单词的缩写形式，你绝对是在冒风险。(如果我说的不对请改正)
