Mrs. Yuan is a writer. She's kind and often helps the poor people.
One day, on her way her office, she saw an old man (lie) on the ground. She came to him and helped him to get up.
She went (buy) some porridge and bread for him. The old man ate up the food (quick) and thanked her very much. Then she asked, " do you live, Grandpa?"
"I have house, madam," answered the old man. "I have to sleep outside at night."
"How old are you?"
"Ninety-two."
Mrs. Yuan (feel) sorry and went on asking, "Why not live in the old (people) house?"
" I have a son," answered the old man. "They've never let a person who has (child) live in it."
"Where is your son, then?"
"He has no children, so he had to live in the old people's house."
