听力原文: When little Midori was two years old, she often Climbed onto the piano bench and reached for the violin that belonged to her mother, a 38-year-old professional musician. 'Please don't touch my violin, Midori,' her mother scolded. The violin was, after all, worth more than $ 20 000. A professional musician never owns inexpensive musical instruments. But Midori persisted she longed to handle the graceful instrument that made beautiful sounds. Finally, on her third birthday, Midori was handed a package: a tiny violin, about half the normal size. That was Midori's first violin. Almost from the moment Midori was born, her mother knew she was sensitive to music. For several years mother and daughter practiced together day after day. She-was eager to learn. She loved music from the bottom of her heart. Failure often led to tears ,though she never once turned from the instrument. She just could not stop her love for music. Instead, she persisted until the problem was overcome. One day Johnson, an American musician, heard Midori playing the violin. He couldn't believe she was just eight years old. 'She must make a tape and I will take it to the United States, 'the musician said. A famous American violin teacher heard the tape. He, too, had difficulty believing his ears. The playing was absolutely astonishing. He immediately accepted her as a pupil and recommended her for a full scholarship. In 1982 ,Midori and her mother moved to Neat York city, leaving behind a comfortable life in Japan. (33)
