Wang Lin is a ninth grade student. He’ll graduate this summer. He’s changed a lot during the last three years.

In the past, he is shy, and he was afraid to speak in public. He was not good at history. He didn’t like sport. He also lost himself in surfing the Internet.

Now he likes sharing everything with his friends and he gets on well with his friends. He is good at all the subjects, especially in English. He is always first in our class. He takes active part in all kinds of action. Such as last month he won the champion in the 100-meter race.

I hope he will make great progress in math and he’ll be healthier in the future .
