After China's entry into the WTO,the interchange and communication between China and the international community has increased,which exerts great influence on pushing forward the modernization and construction of the various industries in China and requires a large number of people with good command of English.Under these circumstances,English education becomes extremely important.Guangxi,an old revolutionary base area inhabited by minority ethnic groups,is falling behind with its economy,culture and education in comparison with eastern regions of China.A number of English teachers,especially those in middle schools of the rural areas,are provided with little education and few opportunities for advanced study;most of them lack the new teaching ideas,models or methods which could replace the traditional teaching model that centers on the teacher and textbook.As a result,students can't give full play to their subjective initiative with low communication and application capability in English.To confer impetus to English language teaching reform,researchers and scholars have made great efforts in experimenting various teaching models with the hope to find a language teaching model which can meet the demands of the new era and B-SLIM model put forward by Dr.Olenka Bilash is such a model.
