Dear Tom,

Thanks for the picture of your classroom. It's cool! My classroom is cool too but our classrooms are a bit different. [There is|There are|There isn't|There aren't] one big window with yellow blind on it. [There is|There are|There isn't|There aren't] any posters in your classroom but there are some in mine. [There is|There are|There isn't|There aren't] also a blackboard between the noticeboard and the poster. [There is|There are|There isn't|There aren't] two pictures on the wall too but not above the blackboard. The teacher's desk is near the blackboard, below the noticeboard. There is a TV above the desk, as well as in your classroom. We already have our desks with chairs in the class. They are comfortable. What other differences [is there|are there|there is|there are]?

Write soon.

Liz
