My name is Lily. I’m sixteen years old. I have a sister. Her name is Lucy. I’m outgoing and smart. Lucy is quiet.But she is more hard-working than me. We both like playing the piano and dancing. She is better than me. So she always help me with them. We like eating vegetables and fruit. But Lucy also likes eating junk food. She eats it twice a week. It’unhealthy. Last week, we went to Beijing. We visited the Great Wall. We ate Beijing duck and bought gifts for our parents. We had a great time there.


试题分析：这是一篇给材料作文，描述自己和自己的姐妹Lucy。本题给出了具体的材料, 所以在写作时要注意时态，结合所给材料可知，描写生活方式、个性特点和共同爱好时，应该主要用一般现在时，描写去北京旅游时，应该主要用一般过去时。
【亮点说明】
如果文章中使用了非常好的短语或句子会给文章增色，如both、always、like doing sth、help sb with sth。还运用了but ，so等使上下文衔接的更好。
