Hello, boys and girls. My name is Kangkang. I’m from Tianjin. I’m No.1 middle school.
   My mother works in No.1 middle school. She teaches Chinese. My father is a doctor in a hospital. They both work hard.
   On Sunday my mother and I often do some shopping. My mother likes shopping a lot. We will go shopping this Sunday afternoon. My mother says she will buy me a red coat. But I don’t like red. I want a yellow one. My mother says yes to me. I am happy.
   My father doesn’t like shopping at all. He likes animals best. He often takes me to the zoo. My favorite animal is the panda. I think panda are very cute. This Sunday morning my father will go to the zoo with me.
   I love my parents very much. They love me, too. I have a happy family.
