Hello! My name is Wendy. I live in the city. My family doesn't have a car, so I go to school on the bus. There are four people in my family. They are my parents, my brother and I. We live happily together.

    At school, I study very hard. I am very good at English. I often help my classmates with their Chinese and English. I enjoy learning.

    I am a quiet girl. I like reading and listening to light music. I have some friends. We always spend time together, they are very funny and friendly. I wish we can be friends forever.
