I' m Eric. Welcome to our classroom. You can see a nice classroom. A blackboard(黑板) is on the wall. A map of China and a map of the world are on the wall, too. The map of China is old. But the map of the world is new. There is a teacher's desk. An eraser and a ruler are on it.
There are two doors in the wall. Some brooms(扫帚) and a football are behind the door. Fifty desks and chairs are in our classroom. They are our desks and chairs. That is a bookcase. And some books are in it. The students can read them after class but can'ttakeany of them out.
Some flowers are near the window. They are red. We like our classroom. We like our class, too.
