中古是汉语句类的成热与定型时期。此期的句类在义类范畴、形式标记、主体功用、句法构造和句子模式等方面约获得长足的进展,并釀就了一个贯通古今的基本句类体系。中古句类不仅在汉语句类史上占据着重要的一段,而且代表了中古汉语的一个富有特征的立面,应该成为汉语史分期的宝贵参数和可靠依据。 Middle age is the Chinese sentence into a hot and stereotyped period. The clauses of this period have made considerable progress in terms of categories of categories, forms of marks, subject functions, syntactic constructions, and sentence patterns, and they have created a system of basic sentence structures that has been connected with ancient and modern times. Ancient Chinese sentences not only occupy an important part in the history of Chinese sentences, but also represent a characteristic facade of Middle Chinese, which should become a valuable parameter and a reliable basis for the staging of Chinese history.
