CLEANING
— It's time to clean our room. We must do a good job.
— Yes, we must. Let me clean the windows. I can do windows very quickly.
— All right. Then I'll sweep the floor. Yang Ling can dust the desks and chairs and Wu Ying will take care of the radiators.
— Those pictures are rather old. Let's take them down and put up some new ones.
— That's a good idea.
