Shanghai No. 8 Middle School began to use a new bell this term. It helps teachers {#blank#}1{#/blank#} （记起） it is break time. The new bell has three parts. The {#blank#}2{#/blank#} （第一） part lasts 15 seconds. It is made up of {#blank#}3{#/blank#} （可爱的） folk music. Next, there are 20 seconds 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 {#blank#}4{#/blank#} （没有什么）worked. It's {#blank#}5{#/blank#}（更好）now. When the folk music is on, teachers know that class is going to be {#blank#}6{#/blank#} （结束）in one minute."

    Shen Huimin, a teacher at No. 8 {#blank#}7{#/blank#}（赞成） that the new bell is {#blank#}8{#/blank#} (创造性的). "In the past, we usually wanted to add a few words after class. But we often {#blank#}9{#/blank#} （忘记） the time," Shen said. "But now the new bell reminds（提醒） us {#blank#}10{#/blank#} (两次). It's a small change, but it's really solving a big problem."
