Ten years ago, a girl gave me an important gift. It was a smile. It was the early autumn of my first
1_____ (A. term; B. year) at a middle school. I knew nobody. I was very lonely, and afraid to make friends
with 2_____ (A. anyone; B. anybody).
     Then one day, my classmates talked happily with their friends, but I sat at my desk alone as usual. At that
 3_____ (A. moment; B. time), a girl entered the classroom. She looked at me, without a word, smiled. It
made me feel happy and warm.
     That smile changed my life. I started to talk with other 4_____ (A. classmates; B. students) and make
friends with them. The girl with a smile has become my best friend now. All my dark days have gone. Now
I 5_____ (A. believe; B. know) that the world is what you think it is. If you think you feel lonely, you might
always feel lonely. So smile at the world and it will smile at you.
