According to a study，young people prefer text-messaging to talk with friends no matter where they are．They even want to do it under the noses of parents and teachers．It seems that some teenagers just can't stop texting．This could be bad for their studies and health．For example，Ann，a 16-year-old girl from New York，lost feeling in her hands after sending over 100texts a day from her mobile phone．She will have to have surgery （外科手术） on her wrists （手腕） in order to fix the problem．
But texting isn't all bad．It helps to make our lives better in some ways．Today many teenagers greet each other on holidays by sending text messages instead of writing paper cards．"Texting instead of sending letters helps me save my pocket money，"said Chen Qi，16，a boy from Sichuan．"It is also eco-friendly because it saves paper．"
Texting can improve relationships between young people and their parents．In the US，many parents send their kids texts instead of shouting at them．Some say texts are more friendly than spoken messages．It's also easier for teenagers to accept them．
Sending text messages is becoming more and more popular．But when you send text messages，keep the following advice in mind：
◆Don't send text messages while riding a bike or walking along a busy street．It is dangerous．
◆Don't send the same text message over and over again．If you haven't received a reply，send a different message．
◆If you have something really important to say，use the phone or make plans to meet in person rather than using a text．
◆Try to keep the text message short and make sure that your meaning is clear．
◆Be polite．Reply to people when they send you a message．It is good to let people know that you have received their messages．
