Yesterday Tom had no works to do after lunch. So his father asked him go to the bookstore to buy a few books. He walks to the bus stop and arrived there at three. When he was waiting on bus, he saw a little dog. It was going cross the street. Just then a car comes, driving fast. He wanted to save the dog. So it was too late. The dog fell down and doesn`t move. "Poor dog!" he cried. But look! Suddenly he stood up and went away. He was very glad find that it was safe.
