Dear Sally,
I'm Lingling. I'm from China. I want to be your friend. I'd like to introduce(介绍)my family to you.
My grandfather is a farmer. He likes planting vegetables and flowers. My father is a police officer. But he isn't strict. He is kind. My mother is a doctor. She works in a big hospital. She goes to work by bus. I'm a pupil. I go to school by bike.
What about your family? Please write to me soon.
Your friend,
Lingling
