完形填空。

     Although I love my life, it hasn't been a lot of fun as I've been ill for 28 years.

years as a professional singer in restaurants, playing and singing folk songs.   3   that was years ago and times
have changed.   4   I live with mother on a country farm.
     Two years ago, I decided that I would need to have some kind of extra work to   5   my disability pension
(残疾抚恤金).   6   I needed to sleep in the afternoons, I was limited in my   7 . I decided that I would consider
  8   to singing in restaurants.
    My family are all musicians, so I was   9   when I went into our local music store. I explained that I wanted
to sing again but using recorded karaoke music. I knew that discs were very expensive and I really didn't have
a lot of  10  to get started. And  11  you find only three to four songs out of ten on a disc that you can  12  use.

you, doesn't it?" he said. "Come with me."
     He led me  15  the crowded shop and to a bench with a large professional karaoke box on it. He placed his
large hand  16  on his treasure and said, "I have 800 karaoke songs in here. You can take your  17  and I'll record
them for you. That should get you started."
    I  18 . Thanking him, I made a time with him to listen to all the songs and choose  19  that I could sing. I
have come full circle with his help.
     His  20  still warms my heart and makes me do just that bit extra, when I have the chance.
