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.
最好在最前面再幫我用英語寫一段開場白（例如：今天我給大家介紹一下duty report）
