“A是A，B是B”句联的内部构造和外部构成

"A是A,B是B"句联内部各小句一般都是有序排列且有较高的一致性.各小句的前段可以是名词性的,也可以是谓词性的;后段大都重复前段,极少的时候略有变化;中段有条件地容纳状语.各小句的重音分布是"中-轻-重",这与单用的"A是A"小句明显不同."A是A,B是B"句联在结构上是弱自由句联,在表意上不自足.常在小句中作成分,或在复句中与紧邻的其他小句或句联形成各种关系,少数时候也可以单独构成复句.

Interior Constitution and Exterior Formation of "A is A, B is B"

A is A, B is B" is formed by linking two or more "X is X" minimal sentences which have fixed order and high consistency. The "X is X" minimal sentence can be divided into three parts. The first part can be nominal or predicative words or phrases. The second part is usually duplication of the first part, sometimes can have a little difference. The middle part can conditionally have an adverbial modifier. The accent of the "X is X" minimal sentence is "middle-light-stress", which is obviously different from the singly used "A is A". Being insufficient to support itself in meaning, "A is A, B is B" is a bound construction. It can be used in a single sentence, in a complex sentence with other minimal sentence which has a certain relation with it, or sometimes forms a complex sentence by itself.
