     My friend, Dick, has a large police dog. Its name is Jack. Every Saturday afternoon Dick takes Jack

for a long walk in the park. Jack likes these long walks very much.

     One afternoon, a young  man came to visit my friend. He stayed a long time and talked. Soon it was

time for my friend to take Jack for a walk. But the man was still there. Jack became very worried (焦急).

He walked around the room several times and then sat down in front of the man and looked at him. But
