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
