Mr Clarke works in a middle school. He likes reading and often       some books from the library. He       to the radio every morning and reads       after supper. So he knows much and teaches well. His       admire him very much.
Mike, Mr Clarke’s little son, is only nine. He           likes reading books. And he often asks his father some questions. Mr Clarke always thinks he’s too                to understand him and chooses       ones to answer. Of course, the boy is not happy with it.
One day Mike read       about the electric lights(电灯) and was       it. When his father told him to do some housework, he went on thinking of it. He asked       questions, and his father answered all. Then his father said proudly(自豪地), “Fathers always know       than sons!”
The boy thought for a while and said, “    .”
“Oh? Why?”
Mike didn’t answer and asked instead, “Who       the electric lights?”
“    ,” answered Mr Clarke.
“Why didn’t his father invent them, then?”
Looking at his son, Mr Clarke didn’t know       to answer!
