求翻译：以上三个测试结果表明，不论是对统计图的主题还是其中的特殊点或者某一特定段，从9年级到11年级的得分依次升高。具体表现为：在对图所描述的主题信息的理解上，三个年级的学生基本都能读懂图的含义，且区分度不是很大；在对图中各个重要的点和段的理解上，11年级学生在点的识读上明显高于9年级学生，其他方面并未表现出明显的年级差异。但是总体来说，识别能力普遍较高。同时随着问题的具体化，思维量的加大，高年级学生表现出明显的优势。是什么意思？

Specific performance: on the map described in the understanding of information on the subject, students in grades three basic mean
