Shanghai No.8Middle School began to use the new bell this term.It helps teachers remember it is break time.The new bell has three parts.The first part lasts 15seconds.It is made up of lovely folk music.Next,there are 20seconds of silence.The final 25-second bell is a fast-paced march (快节奏进行曲) that seems to tell each teacher,"You have to end class now"
All the students welcome the new bell.Chen Yong,a student,said,"We tried many ways to stop teachers before,but nothing worked.It's better now.When the folk music is on,teachers know that class is going to be over in one minute."
