汉语原因从句用法的探讨——以“因为”从句为例
The Reason Clause in Chinese—With “Yinwei” as the Center

在汉语中表示因果关系的复句里，“因为~(从句)，所以~(主句)”是最常见的表达方式。然而，这样的复句也有省略或不使用主句的用法。本文以“因为”从句为探讨对象，考察何种条件下可以省略主句，达到表示原因的概念。同时，这样的从句还有其他衍生的用法。本文的目的在于将“因为”从句的用法进行分类，并统整其功能。
In the complex sentences expressing the concept of reasons in Chinese, “yinwei~(subordinate clause), suoyi~(main clause)” is the most common expression. However, there are also uses of such complex sentences that omit or do not use the main clause. In this paper, we take the “yin-wei-subordinate clause” to discuss the conditions of the main clause that can be omitted to ex-press the concept of reasons. At the same time, there are other derivative uses of such subordinate clauses. The purpose of this paper is to classify the uses of the “yinwei~” subordinate clause and to summarize its functions.
