To bridge this gap, the current research investigates interaction in EFL classrooms in middle schools in China in terms of： （1） the amount of teacher talk and interaction; （2） the type of teacher questions and teacher feedbacks; and （3） the amount and forms of meaning negotiation. The data set include observation records and observation reports of 140 naturally occurring lessons in middle schools in China. The findings reveal that there is not much interaction in EFL lessons in middle schools in western areas of China, which is shown by class time dominated by TTT （teacher talking time）, teacher questions and feedbacks that do not encourage students＇ responses and very little negotiation of meaning Possible causes are analyzed, and implications of this research for EFL teaching in China, teacher development and further research are also discussed展开更多
