【題目】Music is an international language. The songs that are sung or played by instruments are beautiful to all people everywhere.

Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class, and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street.

Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, politics ，and activities of the American people.

Pop or popular music singers make much money. They make a CD or tape which radio stations use in every state. Once the popular singer is heard throughout the country, young people buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, ail the young people want to meet him or her. Now the singer has become a national star.

【題目】All kinds of people come in to have their shoes shined. Most of them are friendly. But this man was different.

”How much do you make a week, boy?“ he asked me. I felt he was at me.

He kept taking a sharp look round every now and then. All the time I kept wondering where I'd seen his face. Suddenly I knew I'd seen his picture in the post office many times. He was a big robber： by the police in three states!

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

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

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

What could I do about it? Hit him with a can of shoe polish? If only someone would come in!

He kept talking away， “Along with imagination, it takes courage—the courage to take a chance. Start something on a shoestring. ”

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

The policeman was at the window when I cried out，” Officer Dailey， ！ This man's a robber. 99

“ ，” the man shouted angrily. He star-ted to jump off the stand. It didn't go the he planned. He fell flat on his face and knocked him-self out cold.

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

“Well, it really wasn't my idea，” I said. “It was his. He told me if you had courage and imagination you could start something big on a shoe-string. ”
