     Teaching second grade is always a challenge. Each student arrives at school with his own needs and
difficulties. One year, a student called Billy   1   me with his behavior as well as his academic requirements.
He struggled daily with his   2   emotions and often became angry or violent. I knew that, to make   3   
progress, his emotions needed controlling.
     One   4   I tried to help Billy was to have him come directly into the classroom when he arrived at school.
Billy's mom would   5   me to alert (警告) me to a particularly emotional morning at home. Then, I would
focus on   6   his anger and calming him down before the other students arrived.
     One week our class was studying   7  . I thought one way to bring learning into the classroom was to
bring my dog Rocky to school for the day.
     That day began as normal. I was preparing activities focused on dog themes   8   I was told that Billy
had a   9   morning at home and I might need to get him  10 . As I was talking to his mom, Billy  11  into
the classroom. To Billy's  12 , Rocky immediately ran up to his new  13 , wagging his tail and licking Billy's
face with doggy affection. Billy couldn't  14  Rocky's charm (魅力) and began laughing as his anger melted
away.
     Throughout the day, Billy never left Rocky's side, feeding him, being gentle with him and even  15  the
other students while Rocky was sleeping.
     Billy was known for doing anything he could to avoid  16 , but on this day he found a good dog story,
"Clifford's Puppy Days," and read it to Rocky. How  17  I was at the sight of Billy reading happily! My little
dog was able to  18  Billy's day from one of anger and frustration to one of laughter, gentleness and  19 .
     That day Rocky more than helped me with my  20 ; he helped to change the life of a child! After that
Billy's behavior definitely improved.
