　　 People and the sources of air pollution are found in the same places. This means that cities with large populations have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes from cars. Statistics show that 93 percent of all auto trips are within cities. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country.

　　 On the average, we throw away more trash and garbage than the year before. The burning of garbage contributes to air pollution. Many major industries are also responsible for the dirty air in the around cities. The fumes from iron, steel, chemical, and petroleum production add particles to the air.

　　 The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy for traffic may cause headaches for loss of clear vision. Wherever coal and oil are used for fuel, fumes may kill trees and plants and cause metal to corrode. In some of the larger cities, these fumes endanger the live of human beings by contributing to lung diseases and causing early death.

　　 My first performance in front of an audience was coming up soon.

　　 I tried as hard as I could to remain calm, but my heart was racing. I stared down at my sweat-covered, shaking hands.

　　 I looked up again at the audience, realizing that these were real people. They were not just my mum and dad, who would say, “Good job!” even if I messed up the entire piece.

　　 What if I had the wrong music? What if I played the wrong notes?

　　 As it turned out, I was never able to answer these questions because the spotlight (聚光灯) was waiting for me. I grasped my hands tightly together, drying off the sweat.

　　 Slowly I walked to the mud-brown piano in the center of the room. It contained 88 demanding keys, which were waiting impatiently to be played. I swallowed the golf-ball-sized lump (隆起部分) in my throat and sat down. Slowly, I opened the music. Next, I rested my still shaking hands on the ivory (象牙色的) keys.

　　 As my fingers played across the keys, I was becoming more unsure of my preparation for this moment. But the memory of my years of training came flooding back. I knew that I had practiced this piece so many times that I could play it backwards if requested.

　　 Although at one point I accidentally played two keys instead of the intended one, I continued to move my fingers automatically (自动地).

　　 My eyes burned holes into (were fixed on) the pages in front of me.

　　 There was no way that I was going to lose my concentration. To keep this to myself, I leaned forward and focused carefully on the music.

　　 When I came to the end of the page, a warning went off inside my head: DON’T MAKE A MISTAKE WHEN YOU TURN THE PAGE!

　　 Needless to say, I obeyed myself with all my heart and mind. And, proud of my “page-turning” feat (技艺), I finished the rest of the piece without making a single mistake.

　　 After the final note died away, a celebration went into action inside my head. I had finished. I had mastered the impossible.
