| Look! This is our classroom. It's not too big or too small, but very clean and nice. It has two doors and six windows. The doors are white and the windows are green. There are thirty-two chairs and desks in the classroom. They are blue. In front of the big blackboard is our teacher's desk. Miss Zhang is working beside the desk. There are many exercise books (练习本) on the desk. We love Miss Zhang. She is a good teacher. You can see a lovely clock above the blackboard. It looks like a bear. Mmmm...What time is it now? It's 3:40 in the afternoon. We're having a computer class in the computer room. We are not in our room now. |
