Today，more and more people use cell phones while they are moving，putting themselves and othes in danger．These people are called the"Heads-down Tribe（族）"．Are you a heads-down tribe member？
More and more traffic accidents are happening because more drivers use cell phones when they are driving．In order to make drivers pay more attention to driving，some traffic rules have been set down．For example，heads-down tribe members who use cell phones while driving in Taiwan will be fined．Drivers who break the traffic rule will be fined NT3，000andmotorcyclists（騎摩托車的人）caughtusingcellphoneswhendrivingwillhavetopayNT1，000．
As we can see above，keeping heads down and using cell phones may cause accidents and even cost much．Besides，more and more interesting and strange facts happen to the"Heads-down Tribe"．Let's have a look at an interesting TV report．A man in America kept using his cell phone on his way home．As a result，he bumped（碰撞） into a big lost bear．When he raised his head，he was so frightened that he turned round and ran away as quickly as possible．Another fact is that we can often see people in the restaurant eating face to face but focusing on their own cell phones．It's strange that they don't talk to the ones who sit opposite to them during the meal．Some of them even have fun communicating with others on the phone．
Cell phones are helpful and necessary tools for modern people．Are cell phones good or bad？It depends on how people use them．Let's be"health"users and try to be the"Heads-up Tribe"．
