双语教学是目前中小学教学改革的重要举措之一。有效地进行双语教学可以使学生在学习学科知识的同时提高其英语水平。但双语师资是制约双语教学的主要瓶颈之一。中小学双语教学要求对合格的师资进行培养,实行资格认证制度,实现双语师资的可持续发展。 Bilingual teaching is one of the important measures for the reform of primary and secondary education. Bilingual teaching effectively enables students to improve their English while learning the subject. However, bilingual teachers restrict one of the major bottlenecks in bilingual teaching. Bilingual teaching in primary and secondary schools requires the training of qualified teachers and the implementation of a qualification system to achieve the sustainable development of bilingual teachers.
