I know I should have told the headmaster at the time. That was my real 36 . He had gone out of the study for some 37 , leaving me alone. In his absence I looked to see 38 was on his desk. In the 39 was a small piece of paper on which were written the 40 “English Writing Prize 1949. History Is a Serious of Biographies (人物传记)”. A(n) 41 boy would have avoided looking at the title as soon as he saw the 42 . I did not. The subject of the English Writing Prize was kept a 43 until the start of the exam so I could not 44 reading it. When the headmaster 45 , I was looking out of the window. I should have told him what had 46 then. It would have been so 47 to say: “I’m sorry, but I 48 the title for the English Writing Prize on your desk. You’ll have to 49 it.” The chance passed and I did not 50 it. I sat the exam the next day and I won. I didn’t 51 to cheat, but it was still cheating anyhow. That was thirty-eight years 52 when I was fifteen. I have never told anyone about it before, 53 have I tried to explain to myself why not. The obvious explanation is that I could not admit I had seen the title 54 admitting that I had been looking at the things on his desk. 55 there must have been more behind it. Whatever it was, it has become a good example of how a little mistake can trap (使陷入) you in a more serious moral corner (道德困境). 36. A. plan     B. fault   C. grade  D. luck 37.
