题型：单项选择题
Long ago, there lived a clever man in China. He was famous for his wide knowledge. And lots of people from all over the country came to learn things from him. The great man taught his students with all his heart and answered their questions with great patience(耐心).
One day a student asked him, “My dear teacher, didn’t you say you have more questions than we do? But we think we students have a lot more than you.” With a smile, the teacher drew two circles—one is as large as a big plate, and the other smaller.
“Of course, I’ve learned much more. But I don’t think I know all you know. Now, look at these two circles：Inside the big one is my knowledge of things, and inside the smaller one is yours. Out of the circles is what we don’t know. My circle is larger, so its line is longer. That means I have more chances to meet with what I don’t know. And that’s why I have more questions than you. The more you learn, the more questions you’ll have. You will never learn enough, you know.”
