Today, an increasing number of people are always looking at their mobile phones with their heads down. These people are called the “Heads-down Tribe( 低头族 )”. Are you a heads-down tribe member? Heads-down tribe members now can be seen everywhere. More and more traffic accident s are happening because drivers use mobile phones when they are driving. In order to make drivers pay more attention to driving, some new traffic rules have been made. For example, heads-down tribe members who use mobile phones while driving will be fined ¥200. As we can see above, using mobile phones may cause accidents and even cost money. Besides, more and more interesting things happen to the “Heads-down Tribe”. According to a piece of interesting TV news, a man in America kept using his mobile phone on his way home. Suddenly, he bumped( 撞上 ) into a big lost bear. When he lifted his eyes from the phone, he was so scared that he ran away as quickly as possible. Another fact is that we can often see people in the restaurant eating face to face but looking at their own mobile 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 all the time. Mobile phones are helpful and necessary tools for modern life. Are mobile phones good or bad? It depends on how people use them. Let’s be “healthy” users and try to be the “ Heads- up Tribe”.
