American Classroom Rules
1. If the teacher asks a question, you should 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 don't know the answer, it's all right to tell the teacher that you don't know. Then he or she knows what you need to learn.
2. There is no excuse for not doing your homework. If you can not go to school, you should call your teacher or your classmate and ask for the homework. It is your responsibility（责任）to find out what homework you have missed. It is not the teacher's job to remind you of missed homework.
3. You must not be absent(缺席) on a test day. If you are badly ill, call and let the teacher know you will not be there for the test. If your teacher allows you to take a makeup, you should take the test within one or two days after you return to class. Bad illness is the only reason for missing a test.
4. Be on time! It's not polite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books out of your bag before you come into the classroom. Then go to your seat and sit quietly. In the US, it is not necessary to knock at the door before you come into the classroom.

五花山

    小朋友，你们说山是什么颜色的？

我家就住在大山里，我知道山是什么颜色的。

    春天的山是绿色的，可那绿是浅浅的，许多树叶儿冒出芽来，嘴上还带着嫩嫩的黄色呢。

    夏天的山也是绿色的，可那绿是深深的，一片片树叶，不管是大的还是小的，都像被绿色的蜡笔涂了，连雨点落上去，都给染绿了。

    秋天的山呀，可不再是一个颜色了。下了一场秋霜后，你看吧：有的树叶变成了金黄色，好像所有的阳光都照到那里去去了；有的树叶变成了杏黄色，远远看去，就像枝头挂满了熟透的杏和梨；有的树叶变成了火红色，风一吹，树叶跳起舞来，就像一簇簇火苗在跳跃；还有的树叶变得紫红紫红，那颜色就像剧场里的大幕布。只有松树不怕秋霜，针样的叶儿还是那样翠绿翠绿的。

    秋天的山就是这样五颜六色。一层金黄，一层翠绿，一层火红„„人们给五颜六色的山起了个名字，叫“五花山”。
