Jercy Page was ninety years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Jercy Page sleeping. Actually, he did not even own a bed. He never needed one. The only rest that Jercy Page got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They asked him many questions, hoping to find an answer. They found only one answer that might explain his condition.

"Mary, didn&39;t you ever wonder what you are really like？ Well, you now have that girl&39;s opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said. " I did as he directed and discovered to my surprise that about half the things were true. Some of them I couldn&39;t change (like being skinny), but a good number I could and suddenly wanted to change. For the first time in my life I got a fairly clear picture of myself. I brought the list back to Daddy. He refused to take it. "That&39;s just for you," he said. "You know better than anybody else the truth about yourself, once you hear it. But you&39;ve got to learn to listen, not to close your ears in anger or hurt. When something said about you is true you&39;ll know it. You&39;ll find that it will echo inside you.

I have to believe that a great teacher is a great artist and that three are as few as there are any other great artists. It might even be the greatest of the arts since the medium is the human mind and spirit. My three teachers had these things in common: They all loved what they were doing; they did not tell, but stimulated a burning desire to know. Under their influence, the horizons sprang wide and fear went away and the unknown became knowable. I shall speak only of my first teacher because in addition to the other things, she brought discovery. She aroused us to shouting, book-waving discussions. She had the noisiest class in school and she did not even seem to know it. We could never stick to the subject. Our speculation (思绪) ranged the world. She breathed curiosity into us so that we brought in facts or truths shielded in our hands like captured fireflies (萤火虫). She was fired, and perhaps rightly so, for failing to teach fundamentals. Such things must be learned. But she left a passion in us for the pure knowable world and she inflamed me with a curiosity which has never left. I have had many teachers who told me soon-forgotten facts but only three who created in me a new attitude a new hunger. What deathless power lies in the hands of such a person？ 21. In the writer’s opinion, school life is usually . A. exciting B. interesting C. tiresome D. challenging 22. We can infer from Paragraph 2 that . A. it is easy to find great artists as well as great teachers. B. there are few great teachers but many great artists. C. the greatest artists are not easy to find; nor are the greatest teachers.

A. teach students the fundamental things B. stick to one subject and be strict with students C. teach students the knowledge ranging the world D. arouse students’ curiosity and desire for the world 24.
