It is very important to be polite in class as a Middle School student. First, I believe when the teacher talks,the polite students should be a good listener. Even you have some questions about the content, you should wait until the teacher stop talking to raise up your hand and ask your question. Second,it is polite to turn off your cellphone when teacher begins the class. Meanwhile, Some teacher should follow the same rule. Last but not least, learning is the best way to show your respect to your teacher. Studying hard is also a way to show how polite are you.
