I didn’t remember sending the   48   handwritten(and not very neatly) on the bottom of her   49   semester transcript.

For three years I have been planning on walking into your office and giving you this note and this transcript.” She handed me her   52   transcript, 3.502. “I would like the paperwork for Graduation with Distinction.”

“I’m not   41 ,” I shouted. “I’m just looking for a friend.”
“When he comes,” one man said, “we’ll   42  him up to your room.”
In a minute I   43  myself in a small room. In no time they undressed me and covered some other things   44  me. One man said “If you need anything, press the button.”
“I want to get my   45   back.” I begged.

“Thank God you finally came,” I said.
“It hurts that badly?” he asked.
“No, on the contrary, I am not ill   50 .”
Dr. Ward looked   51 . “If you don’t feel any pain, that means it’s much more   52  than we expected.” Then he turned to his students: “This is the most difficult kind of patient to deal with because he refuses to   53  that he is ill. __54__ he won’t tell us where it hurts, he will never be well again until we find the hurt out for   55  by doing exploratory surgery (手術(shù)探查) .”

If we were to keep a record of all the things we worried about during a given period of time,we would discover—in reviewing them—that the great majority of our     16     never come to pass. This means that most of the time we     17     to worrying,even the constructive(建設(shè)性的)kind that prompts us to try to come up with a     18     to what is troubling us,is wasted.     19   ,we not only caused ourselves unnecessary mental pain,but also    20   valuable minutes and hours that could have been spent elsewhere.
To     21     this,it is often necessary to subject(使……遭受)potential     22     of worry to the coldly objective. Once,before a major     23     in front of a standing-room-only audience,a member of Arturo Toscanini’s orchestra approached(接近)the great Italian conductor with a terrible    24   on his face.“Maestro(大師),”the musician said     25   ,“my instrument is not working     26   .I cannot reach the    27    of E-flat.Whatever will I do?We are to     28     a few moments later.”
Toscanini looked with total     29      at the man.Then he    30     kindly and placed an arm around his shoulders.“My friend,”the maestro replied,“do not worry about it.The note E-flat does not    31   anywhere in the music that you will be    32   this evening.”
The next time we find ourselves in the middle of     33     about some matter,we might be wise to    34    and ask ourselves what the odds(幾率)are of the problem really coming to    35   .We may be able to go on to something more constructive.
