　　Tell the Ss： A is sweeping the floor while B is cleaning the blackboard.

　　Divide the class into two groups. Tell one group to mime writing. Tell the other group to mime reading. Say Group A is writing while Group B is reading.Get the Ss to practice this sentence as they mime.(You may need to help the Ss by demonstrating the mime.)

　　Drill this structure：

　　T： Group B： draw (Group B mimes drawing a picture)

　　Ss： Group A is writing while Group B is drawing a picture.

　　T： Group A： play pingpong (Group A mimes playing pingpong)

　　Ss： Group A is playing pingpong while Group B is drawing a picture， etc.
