常言道:读史使人明智。但历史包罗万象:政治、经济、军事、科技、文化、思想、天文、地理、民俗等各方面的知识交织在一起,点多面广,错综复杂,要想学好它还真不是件容易的事。在历史学习中经常会出现这种情况,相同的年龄、相近的智商、相同的老师,一样的学习环境:有的学生学得? As the saying goes, reading history makes people wise. But history is all-embracing: political, economic, military, science and technology, culture, ideology, astronomy, geography, folklore, and other aspects of knowledge are intertwined. They are multifaceted and intricate, and it is not an easy task to learn it. This is often the case in history studies where the same age, similar intelligence, the same teacher, and the same learning environment are used by some students.
