Respect your teachers.

First of all, students should respect the teachers. You should      your teachers in the classes. That means to give your respect to him, to stand from your chairs when the teacher enters the classroom, etc. Attend any class attentively. In class of a certain subject or a teacher you don’t like very much, if it is totally anarchy(无政府状态), how can we talk about respect?

Play by the     .

If your teacher wants you to take notes in class, do it. If she tells you to sharpen your pencils only before class starts, listen to her. If she     late homework, do yours on time. Sometimes classroom rules seem strict or even silly, but most teachers know what’s necessary to make things run well and what it takes to let the learning begin. And the better the learning environment, the      you will be!

Expect him/her to like you.

Teachers are teachers because they like kids. Given the chance, most teachers want to be your    , too. Respect your teacher, but do not be afraid of him/her. He/ she wants you to have a great school year just as much as you want to have one!

Put first things first.

Friends are a fun part of school. But they are not the most important part. When your teacher is teaching, give him/her full attention,      when it’s hard to do. Class will end and the ten-minute break will come soon enough, and that’s the time for playing with your friends
