It was a very cold morning as it had been raining very heavily the previous night.As my mother was feeling a little under the weather，my sister volunteered to drive me to school.I had overslept and as a result，was running a bit late for school.We got into the car hurriedly.The road was already crowded with traffic.It appeared that everyone was late as well.
    My sister was a careful driver and despite the fact that I was already late，she refused to drive fast on the slippery road.I was lucky she was such a resolute and careful person because a few hundred meters away from the school，we witnessed a tragic accident.It all happened very quickly，as most accidents do.A car full of school children had made a left turning without signaling and as a result，a school bus crashed into it.A few cars behind the school bus rammed into the bus as they could not brake in time and soon it became a pile-up.The already crowded road became jammed with vehicles that came to a crawl.I told my sister that I wanted to help the victims and she nodded silently.She stopped the car not too far from the accident spot.
    The scene that greeted us was something I would never forget.It left an unforgettable memory in my mind to date.The impact of the accident had made the school children seriously injured in the car.The driver，a lady，lay on the steering wheel.I rushed to the children who were preschoolers.Two of them were seriously hurt and bleeding from the heads and hands.They were conscious although too weak to realize what had happened.In the meantime，passers-by had called the ambulance and while waiting we tried as best as possible to help the victims.
