英语“冠词+名词”表类指概念生成于对事物的内部和外部空间量化。本文通过内部空间量化分析，发现“冠词+名词”表不同类指概念的动因在于其内部不同的概念特征；通过外部空间量化分析，发现当“冠词+名词”表类指概念时,其所指物体或物质从外部概念化为一个外部量点,通过突显内部“任意单量点”、“典型单量点”、“任意多量点”和“全量幅”概念，生成了“以任一量点为代表的类”、“以典型量点为代表的类”、“以任意多量点为代表的类”和“以量幅为代表的类”四种不同的类指概念。

The generic concepts of English “Article+Noun”s are generated from the internal and external spatial quantification of things. Through the analysis of the internal spatial quantification, the paper finds that the reason why the “Article+Noun” can express different generic concepts lies in its different features of the internal concepts; Through the analysis of the external spatial quantification, the paper finds, that when an “Article+Noun” is used for generic references, the things or substance it refers to is externally conceptualized as one external quantity point. Internal concepts as ANY QUANTITY POINT、THE TYPICAL QUANTITY POINT、ANY QUANTITY POINTS、THE MAXIMUM QUANTITY EXTENT are highlighted, which leads to four kinds of generic references as THE CLASS AS REPRESENTED BY ANY QUANTITY POINT, THE CLASS AS REPRESENTED BY ITS TYPICAL QUANTITY POINT, THE CLASS AS REPRESENTED BY ANY QUANTITY POINTS and THE CLASS AS REPRESENTED BY QUANTITY EXTENT.
