Where is my pen?
Tommy is in the classroom, and cannot find his pen--- he needs to write down his homework! The teacher helps him to look for(寻找) it.
“What’s the matter, Tommy?” says the teacher.
“I can’t find my pen,” says Tommy.
It is Tommy’s favourite pen. But it is not in Tommy’s bag. Tommy looks in the computer room, but the pen is not there. He goes to the library. He can look if it is open, but it is closed!
Tommy’s teacher asks if it is in the dining hall, but Tommy doesn’t write in the dining hall. He doesn’t write in the gym, either. He goes to the science lab, but it is closed too.
“Is it in the classroom?” says Tommy’s teacher.
“No, it’s not there…” says Tommy.
“What’s that on your desk?” says his teacher.
“It’s my pen!” says Tommy.
