五年級英語作文：My Sister350字

My sister is seven years older than I. She is pretty with big eyes and black long hair. She is a university student. When she gets back from her university at the weekends, I often chat with her for a long time. I regard her as my best friend. When I get into trouble, she always helps me. She often gives me some good advice on my studies, and tells me to study English well.
　　　　I'm proud of having such a good sister.
