无主句和不确定主语的理论释疑和教学探索

在葡萄牙语语法中,无主句和不确定主语之所以值得比较,是因为二者在概念、结构和语义方面存在诸多交叉和需要释疑的部分。该文从无主句和不确定主语的理论入手,对无主句和不确定主语的概念和语义内涵进行释疑,并通过三个角度(葡萄牙语语法构建、汉葡语法对比、应用型复合型外语人才培养),以对比教学为主要理论指导,剖析无主句和不确定主语的教学需要,重构无主句和不确定主语的教学思路,提供具体的教学策略。

The Theoretical Explanation and Teaching Exploration of Non-subject Sentence and Uncertain Subject

In Portuguese grammar,the reason why non-subject sentence and uncertain subject are worthy of comparison is that they have many overlapping parts needing to be explained in terms of concept,structure and semantics.Starting with the theories of non-subject sentence and uncertain subject,this paper explains the concept and semantic connotation of non-subject sentence and uncertain subject,and from three perspectives(Portuguese grammar construction,Chinese-Portuguese grammar comparison,and training of applied compound foreign language talents),analyzes the teaching needs of non-subject sentence and uncertain subject and reconstructs the teaching ideas of non-subject sentence and uncertain subject with comparative teaching as the main theoretical guidance,in order to provide specific teaching strategies.
