Jack is a famous writer now. But he said he was not a good student when he was young. He was
often late for class and didn't like doing his homework. Sometimes he slept in class while the teacher
was teaching. He didn't understand much, but he always thought he understood everything.
One day the teacher asked the students a question, "When John was ten years old, his brother was
