一、Flora 在网络上发起了以“Let me take a look at your school”为话题的讨论。请阅读她对学校和教室的介绍，圈出 there be 句型中的 be 动词，并仿照示例在方位介词下方画横线。
Today is my first day in my middle school. I like it so much! There is a sports field in the middle of my school, but there isn't a music hall. A library is in front of the sports field. And our classroom building is behind the sports field. Is there a dining hall? Yes, there is. The dining hall is next to the classroom building.
My classroom is large and clean. There are 40 student desks in the classroom. There is a blackboard and a smart screen in the front of the classroom. The teacher's desk is in front of the blackboard. There is also a blackboard across from the smart screen. There aren't any lockers in it, so we put things in the desk drawers. Are there any bookshelves? Yes, there are. They are next to the teacher's desk.
