A
I’ve been having trouble concentrating on one thing. It made school difficult for me. When everyone else in the class was focusing on tasks, I could not.
In my first literature class, Mrs. Smith asked us to read a story and then write on it, all within 45 minutes. I raised my hand right away and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to do it. ” She glanced down at me through her glasses, “You are not different from your classmates, young man.”
I tried, but I didn’t finish the reading when the bell rang. I had to take it home.
In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn’t get much education. But Louis didn’t give up. Instead, he invented a reading system of raised dots（点）, which opened up a whole new world of knowledge to the blind.
Wasn’t I the “blind” in my class, being made to learn like the“ sighted” students? My thoughts spilled out and my pen started to dance. I completed the task within 40 minutes. Indeed, I was not different from others; I just needed a quieter place. If Louis could find his way out of his problems, why should I ever give up?
I didn’t expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day — with an “A” on it. At the bottom of the paper were these words: “See what you can do when you keep trying?”
Inspired and touched, I began to keep trying hard in my study and struggled against attention problems. I believe one can find his way out of difficulty with determination（决心）and efforts.
