Everyone that lives in big cities such as Beijing．Shanghai，Guangzhou etc，knows that there is a lot of traffic!Wherever you go，you can see the crowded streets with cars，buses，bikes and people．It seems that everyone is always in a hurry!In such a situation，accidents might happen．But if we all slowed down a little and paid more attention to the traffic rules，accidents would be avoided （避免）．However，sometimes the fact isn't like that!

How many times have you tried to cross the street even when the light has become red？It seems as if it would be so easy to just quickly run across，or rush in between cars and buses．But this causes a dangerous problem．Crossing the street when the light is red will only save you a few seconds．It is not worth risking（使…冒险） your life．

When I was growing up，my mother always told me the two savings"better safe than sorry"and"better late than never"．That's to say，it is always better to be careful and arrive safely at the place where you hope to go．Things would not be much worse if everyone would wait their turn to cross the street．
