Julia的书包去哪了？
Sam: Hi, Julia. You are not happy.
Julia: I lost my schoolbag.
Sam: Is it black and white?
Julia: No, it isn’t.
Sam:What colour is it?
Julia: It’s yellow and black.
Sam: What is in it?
Julia: An English book, a maths book, a Chinese book, a pencil box and three storybooks.
Sam: Wow. It must be heavy. You can ask Miss White. She is at Lost & Found.
Julia: OK. Goodbye!
Sam: Bye!
