The town I live in is about to put cameras at all traffic lights to catch people who run red lights. It  31  me of how many people I’ve seen who take the yellow light as a signal to go faster. I also can’t  32  why people don’t move when the traffic light has turned green. Above all, there are those  33  situations in which someone doesn’t even  34  that the light is red, and just keeps going; that is how many accidents happen. All these situations make me  35  about the purpose of traffic lights.

However, it’s even more  36  to imagine letting people make their own  37  at a crowded traffic crossing. Who decides who goes next?  38  I guess I do like the idea of a system to  39   traffic. And I also do my best to  40  the traffic signals: to go, to be  41 , and to stop when I’m supposed to.

It occurs to me that my  42  have done much the same for me in terms of  43  me how to live. They have given me many  44  lights: to live in harmony with others to help others, to live with  45  and purpose. They have also given me some red lights so that my  46   doesn’t goastray(走入歧途): to watch my temper, and to control my desires. And there have been some yellow lights: to watch how much I drink, to keep control of my behavior, to  47   school regularly and work hard.

If I obey these signals, my life will be as  48  as it can. Just as I’m wise to pay attention to the traffic lights when I’m walking  49  the street, I’m wise to pay attention to the “life  50 ” given me by my parents.
