As for oral practice,telephone response,ordering,stage play and debate were undergone.I think stage play was the most effective way to promote our oral English,for it dramatically turned the boring English into interesting and active dialogues.Stage play was based on many paticipants through which the communication between the students was getting more fluently.
From writing the play to rehearsal then to performance,we made it through by the hard work all of us,so it was very meaningful and impressed me a lot.So,in my point of view,the stage play is no doubt the most effective.
