一个关于运动事故的英语作文 要一个故事

Last weekend a traffic accident happened at the second crossing on the Xinhua Road at thirty past nine。A young man was riding a bike across the traffic lights。Having seen the red light,he still rode,knocking down an old lady。She was badly injured and someone phoned the first aid center。The ambulance arrived a few minutes later,sending the lady to the hospital。
I was very angry with that young man and sorry for the poor lady。As citizens,we should obey traffic rules and do as laws command,or our safety cannot be ensured。不知道有没有语法错误,应该是对的
