What is the purpose of bilingual teaching in China? Objectively speaking, the purpose of implementing bilingual teaching in China at present is not out of the need of racial assimilation, cultural identity and social stability, nor is it based on the consideration of harmonious coexistence of ethnic groups and avoiding ethnic division. Its main starting point is to improve English and cultivate bilingual talents to meet the needs of the future development of the country, local areas and students. " As Professor Wang pointed out: "Bilingual teaching is a way to improve students' English level; In terms of concept formation, knowledge transfer, international vision and communicative competence, students receiving bilingual education are obviously superior to those receiving monolingual education. These are foreign research conclusions, which have important implications for bilingual teaching experiments in China. "Today, when the world has entered the 2 1 century, China has joined the WTO, China's reform and opening up has deepened, China has gone global, and the world has also come to China. With the development of the country and society, the demand for bilingual talents is increasing rapidly. English is recognized as the most important international language, and everyone must face this reality. At the same time, the implementation of bilingual education is also to meet the needs of students' future development-students must be bilingual and bilingual talents in order to do scientific research, obtain information, go abroad for further study, apply for jobs in joint ventures or seek "high-paying" jobs. This is the necessity of national and social development. In China, not only many developed areas are aware of this, but also the local administrative leaders and far-sighted school managers in western areas, some poor areas and even mountain schools are clearly aware of this. "Planting trees for ten years, educating people for a hundred years." Education obviously takes a long time. If students wait until they graduate from high school or even university, their mastery of foreign languages such as English obviously can't keep up with the needs of national and social development.
