写作是英语运用的重要形式之一,但目前中国大学生生英语写作在课堂教学中过分地强调词汇或语法,忽视了句际的连贯。本文从功能语法中的主位及主位推进理论角度出发,在写作教学中重视句与句的内部联系,通过比较法从而证实运用主位推进理论能使句子与句子间的联系更紧密,更富有逻辑性,突出了“主位教学法”的现实意义。 Writing is one of the most important ways to use English. However, at present, Chinese college students’ writing emphasizes vocabulary or grammar too much in classroom teaching and neglects the inter-sentence coherence. From the perspective of the thematic and thematic progression in functional grammar, this thesis emphasizes the internal relations between sentences and sentences in writing teaching. Through comparison, it proves that using the Thematic Progression Theory can make the relations between sentences and sentences closer and more Logical, highlighting the “thematic teaching method, ” the practical significance.
