I saw an accident happened on my way to home this afternoon. A girl was crossing the

street on a zebra crossing while a young man drove a motorbike towards her. The young

man saw the girl and tried to stop, and he drove too fast to stop. He hit the girl and fell

off her motorbike. The girl was badly hurt and couldn’t move. The young man didn’t

know how to do. I ran to a phone box nearby and dialed 110. Soon the police reached.

They sent her hospital at once. One of the policeman talked to the young man and wrote

something down while was talking. I think it is very dangerous to drive very fast.
