In many high schools，there are strict rules about using mobile phones. If your phone rings in class，for example，the teacher will be very angry.

Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now，there is a ringtone called “mosquitotone (蚊子铃声)”. Using it，students can receive calls and text messages (短信) in class but the teacher will not realize what is happening. How?

Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older，we are unable to hear some sounds with high frequencies (频率). As a result，a child or teenager can hear the mosquitotone ringtone, but it’s_inaudible_to someone 20 or older.

But sometimes，people over 20 can hear the ringtone. One British student’s phone uses mosquitotone. In class，the student’s phone rang. The 32­year­old teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class.”

Not all the students are interested in mosquitotone. Jerry Jones，a high school student of 17，says，“Using mosquitotone too often is bad for our hearing. I may use it for pleasure，but not in class. It’s unfair to the teachers！”

What do parents think of mosquitotone？“I think it is perfect for places like movie theaters，” says Connie Neeson,44.“Think about it. Yon’re watching a film and someone’s mobile phone rings. Mosquitotone is good because many people don’t hear it. However，it also has a bad influence on their study if students use it in class.”

New rules and behavior standards（标准）for middle school students came out in March．Middle School is going to use a new way to decide who the top students are．The best students won't only have high marks．They will also be kids who don't dye their hair，smoke or drink．The following are some of the new rules．

Tell the truth．Have you ever copied someone else’ work in an exam? Don’t do it again! That's not what an honest student should do．If you have played computer games for two hours in your room，don't tell your parents you have done homework．

Do more at school．Good students are kind to other people and love animals．April is a bird loving month in China．Is your school doing anything to celebrate? You should join! That way，you can learn more about animals and how to protect them．When mote people work together，it makes it more fun for everyone．

Have you ever quarreled with your teammates when your basketball team lost? Only working together can make your team stronger．Be friendly to the people you are with．Try to think of others，not only yourself．

Be open to new ideas．Have you ever thought that people could live on the moon? Maybe we will discover Earth Ⅱ some day．Don't look down on new ideas．Everyone's ideas are important．You should welcome them，because new ideas make life better for everyone．

Protect yourself．Has someone ever taken money from one of your classmates? Don't let it happen to you．If you have to go home late，you should take care of yourself and let your parents know．

Use the internet carefully．The internet can be useful for your studies．But something on the internet isn't good for kids，so try to look at Web pages that are good sites for children．Here are some：http：//kiks.Dastday.com；http：//www. chinakids.net.com
