　　If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again. 1 knows this, and nobody would think of 2 the fact.

　　Yet there are many people who 3 to know that the memory works in the same way. When someone says that 4 has a good memory, he 5 means that he keeps his memory 6 practice by exercising it very 7 , either consciously or unconsciously. When someone else says that his memory is 8 , he means that he does not give it enough 9 to become strong. The position is exactly the same as that of 10 people, one of 11 exercises his arms and legs by playing balls, while the other 12 in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own 13 . But if he tells us that he has a poor memory, 14 of us think that his parents are to blame, or that he is just 15 , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind, 16 all of us can improve our strength and our memory by the same means 17 .

　　Have you ever 18 that people who cannot read or write usually have 19 memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.

　　In a word, if you want to have a good memory, 20 practise remembering.

　　He kept giving a sharp __2__ around every now and then. All the time I kept __3__ where I'd seen his face. Suddenly I knew. I'd seen his __4__ in the post office many times. He was the big robber: __5__ by the police in three states!

　　“You know, ”he was saying,“it's imagination people __6__. You'll never get anywhere as a shoeshine boy.”

　　I kept brushing on his shoes as __7__ as I could. The sooner I finished, the better. He said,“When I was sixteen, I had __8__ $ 2 500 of my own.”

　　That reminded me of something. Was it $ 2 500 or $ 5 000 or $ 25 000? I wasn't __9__. I knew a big reward was __10__ for him.

　　But what could I do about it? __11__ him with a can of shoe polish（擦亮剂）? A man his __12__ could grind（压碎）me into the floor. If only someone would come in! He kept talking away（喋喋不休）.“Along with __13__, it takes courage. The courage to take a chance. Start something on a shoestring（鞋带）.”

　　Suddenly I saw Officer Dailey __14__ across the street. Then, real fast, I began tightening the man's shoestrings.

　　The policeman was at the window when I cried out,“Officer Dailey, __15__! This man's a robber.”

　　“__16__,”the man shouted angrily. He started to jump off the stand. But he didn't go the __17__ he planned. He fell flat on his face and knocked himself out cold.

　　“That was __18__ clever of you,”the officer said. “You'll get a reward of $ 7 500 for him.”

　　“Well, it really wasn't my __19__,”I said.“It was his. He told me that __20__ you had courage and imagination, you could start something big on a shoestring.”
