Abstract:In the teaching of English language,Duty Reports play an important role,by providing excellent ground for students who wish to practice speaking English,to experience English culture,and communicate within an overall English framework.Having enjoyed a great and long-standing popularity,both among teachers and students alike,this activity,nevertheless,has exhibited signs indicative of certain deficiencies.Therefore,it has become necessary to update and improve it,as to give it new vitality,prolong and perpetuate its exience.
最好在最前面再帮我用英语写一段开场白（例如：今天我给大家介绍一下duty report）
