My name is Li Lei. Tomorrow is Saturday. We have no classes, but I am going to have a busy weekend. On Saturday morning, I'm going to do my homework. In the afternoon, I'm going to the bookstore on foot. I like reading books so much. I have three science books and eight storybooks now. I want to buy some new books. On Sunday morning, I'm going to play football with my friends. In the afternoon, I'm going to visit my grandparents with my mom and dad. We are going to have a good dinner there. In the evening, I'm going to do word puzzles with my brother. That will be fun.
