Imagine you're in your classroom. It's the end of the break, but your teacher isn't there yet.
You (watch) the pupils. They (do) different things. One girl (clean) the board. Three girls (stand) near the cupboard. They (talk). Some boys (read) comics. A girl (listen) to music. Her friend (write) a letter. One boy (do) his homework. His friend (copy) it. Some boys (fight). Some boys (run) around the desks. And some girls (swap) stickers.
