什么是系统树(文化树)?在科学著作中,作者常常用树枝(或树根,或一棵树)的图表显示同类事物之间的系统关系,这种图表叫系统树。运用系统树的形式来检测考生现代文的阅读能力,是近年来出现的一种较新的题型。例如,一九八六年全国普通高校招生统考的语文试卷中,要求考生根据试题所提供的阅读材料画出加德 What is a System Tree (Cultural Tree)? In scientific writings, authors often use diagrams of tree branches (or tree roots, or a tree) to show the systematic relationships between similar things. This kind of chart is called the System Tree. The use of the phylogenetic tree to detect the ability of candidates to read modern texts is a relatively new type of question that has emerged in recent years. For example, in the Chinese examination papers for the National College Admissions Examination in 1986, candidates were asked to draw Gade based on the reading materials provided in the test questions.
