The town I live in is about to put cameras at all traffic lights to catch people who run red lights．It   36   me of how many people I’ve seen who take the yellow light as a   37   to go faster．I also can’t understand why people don’t move when the traffic light has turned green．Above all, there are those   38   situations in which someone doesn’t even   39   that the light turns red, and just keeps going．That is why so many   40   happen! All these situations make me   41__    the purpose of traffic lights．
42   , it’s even more frightening to imagine letting people make their own decisions at   __43   crossroads．Do the biggest cars get to go first? Who decides who goes next? So I guess I do like the idea of a system to   44   traffic．And I’ll do my best to   45   the traffic rules: to go, to be cautious, and to stop when I’m   46   to．
It occurs to me that my   47   have done much the same for me   48   teaching me how to live．They have given me many   49   lights: to get along well with others, to listen and talk to them, to help others, and to   50   with joy and purpose．They have also given me some red lights   51   my life goes astray（误入歧途）: not to be greedy, to keep my temper, and to control my desires．And there   52   have been some yellow caution lights: to watch how much I drink, to keep control of my behavior, and to   53    school regularly and work hard．
If I obey these rules, my life will be as   54   as it can be．Just as I’m wise to pay attention to the traffic lights when I’m walking across the street, I’m wise to pay attention to the“   55__ signals” given to me by my parents．
