根据韩礼德的系统功能的观点,语言不再是一个以规则为特征的系统,而是以不确定性为基本特征的可供语言操用者任意驾驭或提取的意义潜势。教学的目的就是能使学生发展潜势,根据语境选择适合的语言。在教学方法上,充分地学习语境,利用语境和建构语境,并以此来提高学生的语言能力和语言运用能力。 According to Halliday’s system function point of view, language is no longer a system characterized by rules, but it is the potential significance of arbitrarily manipulated or extracted linguistic operators with uncertainty as the basic feature. The purpose of teaching is to enable students to develop their potential and choose the appropriate language according to their context. In terms of teaching methods, we should fully study the context, use the context and construct the context to improve the students’ language ability and language use ability.
