Peter Judd joined the army 26 he was eighteen, and for several months he 27 (teach) how to be a good soldier. He did quite well in everything when 28 shooting. One day he and his friends were practicing _was taught 29except (shoot), all of shooting 30whom were doing quite well except Peter. After he had shot at the target nine times and had not hit it once, the officer 31 was trying to teach the young soldiers to shoot said, You’re quite 32 (hope). Peter! Don’t waste your last bullet too! Go behind that wall and shoot yourself with it!
Peter felt ashamed. He went behind the wall, and a few seconds later the officer and the 33 young soldiers heard the sound of a shot.
Heavens! the officer said, Has that silly man really shot 34 ? He ran behind the wall 35 (anxious), but Peter was all right. I’m sorry, sir. he said, but I missed again.”

解析：【小题1】后边是一个时间状语从句，表示“当……时候”，故用when【小题2】主语“他”和动作“教”之间是被动关系，故用被动语态，并且是发生在过去的事情，故用一般过去时的被动语态【小题3】这里表示“除了射击，其它的事情他都做得相当好”。Except表示除……之外【小题4】practice doing是固定用法，意思是练习做某事，所以填shooting【小题5】这是一个定语从句，关系词在定语从句中作主语并且是人，构成介词+关系代词的结构，故只能用whom【小题6】这是一个定语从句，关系词在定语从句中作主语并且是人，所以既能用who也能用that【小题7】这里作表语，故需要用形容词形式【小题8】这里表示其他的，故用other【小题9】这里表示“他自己”，故用反身代词【小题10】这里修饰动词“ran”，故用副词

就是这个解释
