He was 22 so much that he couldn’t get to sleep. He wouldn’t join the army because he was in love with a beautiful girl. “If only I could find a 23 to make the doctor believe there is something 24 with my body,” he thought and thought. Suddenly, a good idea crossed his mind. The next morning Jim got to the 25 on time and was led into a large room. He hurriedly found a seat to sit down and took out an out-of-date newspaper, 26 to read it. Soon it was his turn to be examined. When he came up to the doctor, the old man took a quick and sharp look at him. Then in a 27 he ordered Jim to take off his clothes, go straight to a corner and sit down on a chair there. No sooner had he seated himself on the chair than he heard the doctor murmuring to his assistant: “Finished! The boy is 28 up to the standard.” “How can you draw such a 29 like that before you give me a 30 check? Jim shouted at the doctor. “Don’t be impetuous(冲动), young man! Put on your clothes, and then I’ll 31 it to you,” the doctor said 32 .“You said we didn’t examine you carefully, but I don’t think it 33 for us to do that. When I told you in a low voice to take off your clothes, you did it as I told you. It shows you have good 34 . When you were asked to go and sit on the chair, you did so, too. It shows you can see any subject within a certain distance. 35 , you were found reading the newspaper just now, and we are certain you are a man of intelligence. 36 , you’re perfect in mind and body.” Half a year later, Jim was killed on the battlefield. At the news his girlfriend nearly went 37 . She kept weeping. “Don’t be like that, my dear.” It was an old man’s 38 voice. “Your Jim died a real man. He 39 his life to the people all over the world. It is right that we should be proud of him…” Saying this, the old man, her father, was choked(哽咽). His only 40 was that he had never had Jim know who he was. This old man was the medical officer who had given Jim the health check.
