  There once lived in Greece a learned man．He was so well known for his wide knowledge of almost everything that lots of people from all over the country came to learn things from him. The  great man taught his students whole-heartedly and answered their questions with great patience．（耐心）

    One day a student asked him，"My dear teacher，didn’t you say you yourself have many，many more questions about things than we do? On the contrary（恰恰相反），we students have far more than you．”

    With a smile，the teacher drew two circles―one as large as a big wheel（轮子），the other  smaller．

     "Of course, I've learned much more. But a teacher does not necessarily have fewer questions than his students. Now look at these two cricles. Within the big one is  my knowledge of things, and within the smaller one yours. Out of the cricles is what is still unknown to us. Since mine is larger, the line that  marks  out （划……的界限） the circle is longer. That means I have more chances to face what is still unknown. And that's why I myself have more questions than you do. The more you learn, the more questions you have. You will never learn enough, you know.”
