Mr. King is a tall and strong man. He teaches P.E. in a middle school. He wears a long beard(胡子)and takes good care of it.

It was Sunday yesterday. There was a big football match of the year on the playground in the centre of the city. Mr. king likes the game very much and of course he was going to watch it. With his friends' help he got a ticket a few days ago.

After breakfast he hurried to the bus stop, but a lot of people were waiting there. A bus came and he hardly got on. There were plenty of people in it and it was difficult for them to put their feet. He had to grip(抓住)a back of the chair. At the next stop a boy got on the bus. He was short and couldn't grip anything. Suddenly the bus stopped and the boy hardly fell onto the floor. He looked around and saw Mr. King's beard and grip it. The man found it at once and called out, "Let go of(松开)my beard, boy!"

"Are you going to get off, sir?" asked the boy.
