When I entered Berkeley, I hoped to earn a scholarship. Having been a Straight-A student(优等生), I believed I could  1   tough（=hard） subjects and really learn something. One such course was World Literature given by Professor Jayne. I was extremely interested in the ideas he  2 in class.
When I took the first exam, I was  3   to find a 77, C-plus, on my test paper,  4   English was my best subject. I went to reason with Professor Jayne, who listened to my arguments but remained 5  .
I decided to try harder, although I didn't know what that  6   because school had always been easy for me. I read the books more carefully, but got another 77. Again, I  7    with Professor Jayne. Again, he listened patiently but wouldn't change his  8   .
One more test before the final exam. One more  9  to improve my grade. So I redoubled my efforts(加倍努力) and, for the first time,  10  the meaning of the word "thorough"（彻底的）.But my  11  did no good and everything  12  as before.
The last hurdle（障碍）was the final. No matter what  13 I got, it wouldn't cancel three C-pluses. I might as well kiss the  14  goodbye.
I stopped working hard. I felt I knew the course material as well as I ever would. The night before the final, I even  15  myself to a movie. The next day I decided for once I'd have  16  with a test.
A week later, I was surprised to find I got an A. I hurried into Professor Jayne's office. He  17  to be expecting me. "If I gave you the As you  18  , you wouldn't continue to work as hard."
I stared at him,  19  that his analysis and strategy（策略）were correct. I had worked my head  20  , as I had never done before.
I was speechless when my course grade arrived: A-plus. It was the only A-plus given. The next year I received my scholarship. I've always remembered Professor Jayne's lesson: you alone must set your own standard of excellence.
