My name is Dave. I’m 13. I’m of medium height and I’m a little thin . I have short black hair. I like singing. I also like playing basketball.

Last weekend, I was busy but happy. On Saturday morning, I did my homework at home. In the afternoon, I visited my grandparents with my parents. We went there by car. On Sunday morning I played basketball with my friend. And in the afternoon, I listened to the music and did some reading.

题目分析：这是一篇提纲类作文，题目只给出了主要写作内容，故动笔前先要认真阅读题目，确定写作要点，然后围绕要点适当发挥。写作中，应注意描述的全面性，尽量将提示的内容利用上；结合材料内容，可知本文主要是用一二人称，一般现在时态进行叙述。语言的表述应该符合语法的结构，造句应该符合英语的表达习惯。适当使用连词，做到上下文联系紧密，符合逻辑关系。

【亮点说明】范文运用一些常见短语：did my homework做家庭作业 at home 在家listened to听 did some reading做阅读。Last weekend, I was busy but happy这外句子运用了but连接两个并列的形容词。And in the afternoon, I listened to the music and did some reading这个句子中and连接两个并列的谓语动词，时态保持一致。
