Just as(例舉)the picture shows, some people are using their phones while(時間) they are crossing the street. How dangerous it is to do this way. There are many traffic tragedies due to (因果)the inattention to traffic lights. Though(轉折) the stick can help you, the stick doesn’t have a pair of eyes and it cannot tell you the dangers in front of(方位) you. There are many other disadvantages of overusing mobile phones such as(列舉) making our eyes near-sighted, having less face-to-face communication with our friends and so on(列舉).
