Linda is my best friend. She is 15 years old. She is a pretty girl with a round face and two big black eyes. She always has a smile on her face. She is taller than I.

　Every morning, we go to school together. She studies quite well and she's a top student in our class. She is modest in her behaviour. When I have difficulty in English, I always ask her for help. We are both interested in music. At weekends, we join the same hobby group and play the violin together.

We like each other.

题目分析：这是一篇命题作文，题目是My Best Friend and I, 对内容没有其他的限制。在写作时就要紧扣标题，写是的我的最好的朋友和我，在作文中两者都要有所体现。另外，从题目中可以看出，文章要用第一人称，并用一般现在时。

【亮点说明】

这篇文章内容紧扣标题，结构清晰，内容紧凑，第一段介绍朋友，第二段些我和朋友的关系到最后的总结。文中运用了很多学过的短语，例如with a round face and...,have difficulty in, ask her for help, be interested in， at weekend等，为文章增色不少，。另外用到了学过的形容词比较级，能学以致用。
