Hi! I'm Diandian. Welcome to our class! We will have an English party this afternoon. Now everyone is preparing for the party. Let me introduce my classmates to you! This is our group leader, Tiantian. He is writing some invitation cards (请柬) to his friends. Look! Longlong wants to have an acting show at the party. He is wearing a funny coat. How cool! Oh, who is singing a beautiful song? That's Mengmeng. Some students are listening to her song. What about me? I'm painting pictures for the party. How happy we are! Would you like to come to our party?
