Dear grandma,
How is everything going? Now I am studying in China. I have a good friend. His name is Wang Lin. He is a Chinese boy. He is more outgoing than me, and he is very friendly to me. At school, he often helps me a lot and I like him very much. Although he is shorter than me, he likes sports very much and his favorite sport is basketball. I like basketball, too. We play basketball twice a week. As for study, I think I am a little smarter than him, but he works much harder than me. Both of us can get good grades in every exam.
Yours,
Jeff
题目分析：这是一篇提纲作文。本文作者主要与好朋友王林的不同，全文主要用一般现在时态。
【亮点说明】文中使用了非常好的短语和句子为文章增色不少，例如more outgoing， is very friendly to，a lot ，twice a week，As for study， a little，Both of us 等短语；文中多次运用比较状语如more outgoing than me, shorter than me，a little smarter than him；让步状语从句 Although he is shorter than me。文章层次清晰，内容饱满，表达流畅。
