第三部分阅读理解(共15小题;每小题2分,满分30分)

Richard Charles Rodgers was born in New York City on June 28th, 1902. Both his parents enjoyed singing and playing the piano. His grandparents loved opera and took their grandson to many productions. Richard attended many Broadway (百老汇) shows as a child. Richard began playing the piano by the age of three. At the age of fifteen, he decided that he would work in the musical theater. In the same year, he wrote the music for a stage show presented by a local group of young people. Then, he wrote music for a production of the students at Columbia University.

Richard and his wife Dorothy had two daughters and six grandchildren. One daughter and two grandsons also write music. Richard died in 1979. Books written about his life describe him as a cold man who was often depressed (消沉的). Family members say he was only able to express himself through music.

Other future show business leaders were also involved in the Columbia productions. Two of these men would be very important in Richard’s life — Oscar Hammerstein and Lorenz Hart. Richard once said the show he liked the best was Carousel, the second musical (音乐剧) he wrote with Oscar Hammerstein. Music experts say that a Richard show is always playing somewhere in the world — on Broadway, in theaters in different countries, and in local school productions. And people all over the world still enjoy the movies linked to Richard, such as State Fair, South Pacific, Pal Joey, The Sound of Music, Oklahoma and Carousel.
