When I was thirteen years old, a girl gave me an important gift.
It was the early autumn of my (one) year at a new school. No one knew me. I was very lonely, and afraid to make friends with (everyone). Every time I heard the other students talking and laughing, I (feel) even more lonely. I could not talk to anyone about my (problem).
One day, my classmates are talking with their friends, but I sat (介词)silence. At that moment, (冠词)girl entered the classroom. I did not know who she was. She passed me and then turned back. She looked at me (连词), without a word, smiled.
(Sudden), I felt the touch of something bright and friendly. It made me feel happy, lively and warm. It was like a (hide) treasure. That smile changed my life.
Now I believe that the world (be) what you think it is. If you think you are lonely, you might always be alone. My suggestion is: Smile at the world and it will smile back.
