Nowadays, smart phone has been part of our life. We can see people lowing down their heads and playing smart phones all the time. When people are walking on the street, the traffic regulations are no longer their first concern. It is so dangerous for them to keep their attention on the phone. Dutch officers figured out a new rule to let people realize the traffic lights. On the ground, the traffic light can be seen. What a smart idea. When people are watching smart phones, they can see the lights, too. At the same time, we need to think about the problem that whether our life is controlled by the technology. 
如今，智能手机已成为我们生活的一部分。随处可见的人在低头玩手机。当人们走在大街上时，交通规则已经不再是他们关心的首要问题。大家都把注意力放在手机上是很危险的。荷兰官员想出了一个新规则来让人们看到到交通信号灯。在地面就可以看到红绿灯。这是一个非常棒的主意。人们在看手机的时候也能看到灯光。不过，与此同时，我们也需要思考一下科技是否控制了我们的生活。
