我认为凡是通过教育部等有关主管部门立项审查和专家委员会内容审定合格的教材都可以称为主流教材。在现有通过资格审查并选用的教材体系中,再提出“主流教材”这一概念就容易产生歧义 I think that all through the Ministry of Education and other relevant departments in charge of examination and review of the contents of the Committee of Experts qualified materials can be called mainstream teaching materials. In the existing qualification system and selection of teaching materials, and then put forward the “mainstream textbook” is prone to the concept of ambiguity
