Introduction
With the economic globalization and China’s entry into WTO, the society needs all kinds of talents increasing. To succeed in present society, a person should not only possess advanced subject knowledge, but also master at least one foreign language. The last two decades have witnessed great changes of English teaching in China. But the present English can still not meet the social demand. It is necessary to carry out quality-oriented education to enable the students to use English as the instrument to gain more information required for their improvement in the subject matters. In this new rush for English learning in China, bilingual education has become a hot issue. Not only universities, but also middle schools, primary schools and even kindergartens are proclaiming that they have “bilingual education plan”. Some bilingual subject courses have been set up in many universities, such as Peking University, Qinghua University, Fudan University, Hunan University etc. These courses are taught bilingually by the teachers to help the junior, senior undergraduate students and postgraduates acquire subject knowledge and improve these students’ English. This kind of bilingual education often involves the teaching of subject courses through English while Chinese is also allowed to be used. It is expected to improve students’ English language proficiency through creating more language learning environments and to help them to obtain more subject matters with English as instrument.
