Some teachers start classes as early as five minutes and end classes as late as ten minutes,and the students have very short class breaks,especially before the entrance examinations begin."Not hearing the schoolbell ringing,the teacher kept teaching." This happens very often in Chinese schools.However,head teachers in China often praise the teachers for this.
However,I don't think it is a very good idea to do this.First,when the school bell rings,students and pupils often hope to have a good time after class,but the teacher still kept teaching,and thus the teaching effect is not as good.Secondly,it has a bad effect on studying the next lesson.Thirdly,it has a bad effect on the students' minds and health.So I don't think it is a very good idea to do this.
