     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).
