I'm Wang Lin. Tomorrow is Saturday. I'm going to have a busy weekend. On Saturday morning, I'm going to do my homework. On Saturday afternoon, I'm going to the supermarket. I'm going to buy some food for our picnic. On Sunday morning, I'm going to climb mountains with my parents. Then, we are going to have a picnic. We are going home at about 4:00 in the afternoon, I think we'll have a good time.
