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）".
More and more traffic accidents are happening because more drivers use mobile phones when they are driving. In order to make drivers pay more attention to driving, there are some new traffic rules. For example, people who use mobile phones while driving in Taiwan are fined（罚款）. Car drivers andmotorcyclistswho break the traffic rule will be fined NT$3000 and NT$1000 respectively（分别地）.
As we can see above, using mobile phones may cause accidents and even cost a lot of money. Also, 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 mobile phone on his way home. As a result, he knocked into a big lost bear. When he lifted his eyes from the phone, he was so afraid that he turned around and ran away quickly. Another fact is that we can often see people in the restaurant eating face to face but looking at their own mobile phones.
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 instead of being the "Heads-up Tribe".
