One day Alicia was on her daily walk when she saw a4sitting in a rocking chair under a tree. He looked very old and his hair was white. He looked thin and weak， and his hands were shaking，5 he looked very happy.

He had a wide smile on his6， and his eyes shone with happiness. But Alicia saw that he did not have teeth.
“Good morning!” replied Alicia. “Yes， it is a lovely day.”
