　　A

　　(2019·广东七校联合体高三第一次联考)"You'll be blind by the time you're twenty­five，" a doctor at Children's Hospital predicted. "Your blood sugar is much too high．" It consumed me. No matter where I was or what I was doing, it was overhead like a dark cloud, just waiting for the right opportunity to destroy my world.

　　I liked painting. Losing myself in painting filled me with peace. Painting provided me with the only place where I could escape from those threatening words.

　　When I was twenty­one, my right eye went blind. Precisely three months after my twenty­fifth birthday, I had a massive hemorrhage(大出血) in my left eye because of an accident．For the next twenty years, vision came and went. I went through many eye operations in an attempt to keep my vision. But after one final operation, I lost the battle and all remaining vision. And I buried all dreams of painting.

　　Desperate, I enrolled in(注册) a sixteen­week program for the blind and visually impaired(受损的). I learned personal adjustment and the use of a computer with adaptive software. A whole new world opened up to me through this program.

　　"JAWS and Window­Eyes are leading software for the blind，" my instructor told me. "You can use the Internet, e­mail and Microsoft with all its tools and features．" It's amazing! Hope went up for the first time in years．"By learning how to use hot keys to control the mouse, you can use Microsoft Access, Excel and Powerpoint，" my instructor added.

　　For the next several years, I learned that when one door closes, another door opens. There are plenty of choices available for the blind and visually impaired through the gift of technology. Not only do I have a speaking computer, but I have a speaking watch, alarm clock and calculator.
