I know I should have told the headmaster at the time. That was my real     .

He had gone out of the study for some          , leaving me alone. In his absence. I looked to see     was on his desk. In the    was a small piece of paper on which were written the     “English Writing Prize 1949．History Is a Series of Biographies （人物传记）”.

A（n）     boy would have avoided（避免） looking at the title as soon as he saw the      . I did not. The subject of the English Writing Prize was kept a     until the start of the exam so I could not      reading it.

That was thirty-eight years            when I was fifteen. I have never told anyone about it before,       have I tried to explain to myself why not.

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）.
