A+是+B 这是逻辑中表示性质命题的典型表达式。从语法结构来分析,“A”是主语,“是”是动词,“B”是宾语,这是个判断句。从语用结构来分析,“A”是话题(主题叙述的出发点),“是+B”是述题(对话题所作的说明)。如果作语义分析,“A+是+B”可以用来表示等同或归类关系,除此之外,还可以表示特征(这小孩是黄头发)、质料(那两套茶具是唐山瓷)、领有(这间教室是一个门)、比喻(人眼是秤)等关系。

A + is + B This is a typical expression of a proposition of nature in logic. From the grammatical structure to analyze, “A” is the subject, “yes” is a verb, “B” is an object, which is a judgment sentence. From the pragmatic structure to analyze, “A” is the topic (the starting point of the narrative), “is + B” is the topic (explanation of the topic). If you do semantic analysis, “A + is + B” can be used to indicate equivalence or classification, in addition, you can also feature (the child is yellow hair), texture (that two sets of tea Tangshan porcelain), collar There (this classroom is a door), metaphor (human eye is scales) and other relations.
