His4worship（崇拜）him very much. Mike, Mr Clarke’s little son，is only nine. He5likes reading books. And he often asks his father some questions. Mr Clarke always thinks he’s too6to understand him and chooses_7ones to answer. Of course the boy is not satisfied with（对…满意）it．
One day Mike read8about the electric lights（电灯）and was9　 it．When his father told him to do some housework，he went on thinking of it．He asked him10questions，and his father answered all．Then his father said proudly，“Fathers always know11than sons!”The boy thought for a while and said，“12!”
　　“Oh? Why?”
　　Mike didn’t answer and asked，13，“Who invented the electric lights?”
　　“14.”answered Mr Clarke．
