     As a music teacher, I have always known that music touches the soul. It can   1    all kinds of
barriers to reach students in a very special way. It can be the   2    for each child to find their light. I
would like to    3    a story about it.
     For a few years I was   4    with the opportunity to teach disabled students. One of my most    5   
students was a five-year-old girl called Vanessa, who had difficulty walking, and could not speak.
We   6      sat on the floor for our music lessons and Vanessa liked to    7     on my lap(膝上). One of
her favorite songs was "John the Rabbit. " It was a call and response song where I sang the call and the
students     8   twice while singing the repeating phrase, "Oh, yes! " Vanessa liked to    9    her hands
together with mine and clap with me. We probably performed that song during every class, Vanessa
and I clapping together. But she   10     said or sang a word.
     One day, when the song was finished, Vanessa turned around,   11     me in the eye, clapped her
tiny hands twice and said the words " Oh, yes 1" I opened my mouth in    12     and for that moment I
was the one who could not speak. When my heart    13     started beating again, I looked over at the
assistant teacher to find her also    14     Through music, we had made an awesome connection.
     Several years later, I met Vanessa on the street in town. She waved with a big     15     on her face
and then clapped her hands twice, imitating the song we had     16    so many times in our music class.
The little girl,   17     her connection with music, left an impression on me that will last forever. Every
child has the    18    to learn and grow. It is up to us to   19     the way to reach each and every one
of our students. We all must find each child's   20     .
