Sixteen years ago a boy gave me an important gift. It was a smile.

It was the early autumn of my first year at a new school, and my old school was far away.    41    I was very lonely, and afraid to make friends with anyone.

Every time I heard the other students talking and laughing together, I felt sad.    42    Then one day, my classmates talked happily with their friends, but I sat at my desk unhappily as usual. At that moment, a boy came into the classroom. I didn't know who he was. He passed me and then turned back. He looked at me with a smile.    43    It made me feel happy and warm. That smile changed my life. I started to talk with other students and made friends. Day by day, I became closer to everyone in my class.    44    

One day I asked him why he smiled, but he couldn't remember smiling at me!

It doesn't matter because all the dark days have gone.    45    If you think it lonely, you might always be alone. So smile at the world, and it will smile back.

There was a tree in my garden. One day, two birds came to the tree and built a house for their three newborn（新生的）babies.

One day, I heard the sound of the little birds. I ran to the garden and found two babies eating food on the ground. I thought they dropped（掉出） off their house, so I decided to help them get back to their house. At that time, the father bird and the mother bird came back. They had some food for the third baby. They put the food on the ground，far away from the third baby. To get the food, the baby had to fly to it.

The third baby was hungry, but she was afraid to get out of the house. To my surprise, the father bird and the mother bird just stood there and did nothing.

After about ten minutes, the third baby bird didn’t have any other choice. She slowly went to the border（边缘） of the house and began to fly. She flew off from the house. Finally, the third baby bird landed safely on the ground and found the food.

These birds taught me a lesson：if you want your food, you will have to learn to fly.
