here are some american classroom customs:
*if the teacher asks a question, you are expected to give an answer. if you do not understand the question, you should put up your hand and ask the teacher to repeat the question. if you do not know the answer, it is all right to tell the teacher that you do not know. then he or she knows what you need to learn.
*there is no excuse for not doing your homework. if you are absent（缺席）, you should call your teacher or someone who is in your class and ask for the assignment（作业）. it is your responsibility（责任）to find out what assignments you have missed. it is not the teacher’s responsibility to remind you of missed assignments.
*you must not be absent on a test day. if you are seriously ill, call and let the teacher know you will not be there for the test. if your teacher allows make-up tests, you should take the test within one or two days after returning to class. serious illness is the only reason for missing a test.
*be on time! it is considered（认为）rude to be late. also, it disturbs other students. if you must come in late, be sure to do it quietly. have your books and papers out of your bag before you come into the room. then go to your seat and sit quietly. in the u.s. it is not necessary to knock before you enter the classroom. if you must leave during class, do so quietly. there is no need to ask the teacher’s permission. entering a teacher’s office or any office with a closed door without knocking first is not acceptable. knock first, then wait to be invited in.
*wearing a hat in class is considered impolite by many teachers. some teachers may ignore it, but you should ask permission first.

这里是一些在美国课堂方面的传统：如果老师提出了问题，你就应该积极去寻找答案。假如你没有听懂问题是什么，你应该举手让老师重复一遍问题。万一你不知道正确答案是什么，那也没有关系，就直接告诉老师你不知道吧，这样他就知道你还需要学习。
千万不要为没有做作业而找借口。如果你缺席了，就应该打电话给老师或者让班里的同学转达作业是什么。补上拖欠的工作是你的责任。提醒你补上不是老师的责任。
考试的时候是一定不能缺席的，如果你实在病得很严重，打电话给老师，让他知道你要缺考。如果老师同意让你补考，最后在回到课堂之后的一到两天就补考。唯一错过考试的理由只能是病得很严重。
一定要准时。迟到是被看做粗鲁的表现。同时，迟到也影响到了其他的同学。如果你已经迟到了，那么安静点。在你进教室之前就把书和纸准备好。然后安静地走到你位子上坐下。在美国，进教室之前敲门不是必须的。如果你必须早退，那也请安静点。你不需要询问老师。不敲门就进老师办公室或任何关着门的办公室都是不被接受的。先敲门，再等着别人叫你进去。
很多老师都认为上课的时候戴帽子是不礼貌的表现。有些老师不在意这个，但是你首先得询问他并得到允许。
