Hello, everyone. This is our new classroom. What's in it? Let (A. is/B.us) go and see. There (A. is/B. are) many pads(平板) on our desks. And there is one computer on the ( A. teacher's/B. teachers ) desk. We ( A. has/B. have) a big screen(屏幕) on the wall.
Guess! Where is our door? Look! It's on the screen. We can turn on these (A. lights/B. windows). They are yellow, white and blue.
