     Have you felt annoyed when a cellphone rings during the class? Something must be done to stop this.

Now in New York City, USA, a rule is carried out in schools. Students can't even bring cellphones to

schoo1. Is it a good thing or not?

     Anxious parents say that cellphones are an important tool (工具) in holding New York city's families

together. "I worry about it," said Elizabeth Lorris Ritter, a mother of a middle school kid, "It's necessary

in our everyday life. We have a washing machine. We have running water, and we have cellphones." Many

the cellphone was like all extra (额外的) hand or foot for them. "I feel so empty," said May Chom, 14.

boring trip."
