本文指出,过分强调课堂外语口语是目前大学本科双语教学难以广泛开展的主要问题;提出双语教学的核心是外文原版教材的观点;提出以外文原版教材为核心,强调书面双语的教学模式。这种模式保留了双语教学的全部积极意义,可使得双语教学能够在全国大部份高校中开展。 This paper points out that overemphasizing the classroom foreign language spoken is the main problem that bilingual undergraduate teaching is difficult to carry out widely. The core of bilingual teaching is to put forward the viewpoints of the original foreign language textbooks. The paper puts forward the teaching mode of focusing on written bilingualism with foreign textbooks as the core. This model preserves the full positive meaning of bilingual teaching and enables bilingual teaching to take place in most colleges and universities nationwide.
