属性和Venn图

Today we are going to talk math. Do you know what is an attribute? An attribute is some adjectives that describe an object, for example, blue, smooth, and rough. Do you know what is a Venn diagram? A Venn diagram looks like two or three circles together. Each circle represents an attribute. A Venn diagram is used for sorting.属性就是描述物体的一些形容词。例如蓝色、光滑的、粗燥的等等。Venn图看起来就像是两个或者三个圆交叉，每一个圆代表一种属性，Venn图可以用来给物体分类。
