Ben and Bill are Americans. They aren't brothers. They are good friends. They're in China now. They're new students in No. 5 Primary School. They are in the same grade, but in different classes. Ben is in Class 2, Grade 5. Bill is in Class 3. His classroom is next to Ben's. And the teacher's office is beside Bill's classroom. After school they go home by bus. They are waiting for a bus now.
