At the Beginning of Class

At the beginning of today's class, it was very noisy in classroom, just because Mr. Schick did not be here at that time. Almost everyone talked to each other loudly, they even left their seats and went to play with other students. It seemed that it still was the break time. I stayed in my seat quietly, prepared for religion test and waited for Mr. Schick. I just kept myself quiet, but did not remain others not to speak so loud.
Then, because we were too noisy that has influenced neighbor class, Mr. Mc opened the door that between his classroom and ours, warned us that it was class time, and we should sit down in our seats and be quiet. After that Mr. Schick also came to the class, he talked with us about that seriously, and then left again for a while for his desk.
Because we have just been warned, everyone looked much quieter than before. There still were some people talking though others told them to stop.
In China, most of students would be quiet in class time though teacher were not here. We were taught to do that when we were very young. If we talked to each other loudly like what we did in break time, teachers would be really angry because we would influence other students to listen to teachers. It was a disrespect of them and also was a waste of the time.
