“历史总离不开年经事纬”,有了这个我们才会在学习中省去不必要的麻烦。就拿纪年方法来说,历史上的纪年方法很多,好多学生在学习历史时,对纪年方法颇感难以下手。我国“历史优久,年代遐长,史籍浩繁,事迹错杂”,为此我们更有必要将头绪纷纭的历史事件提纲摘要,纪年方法不失为一 “The history cannot be separated from the past by years.” With this, we will save unnecessary trouble in our study. Take the method of years of the year, there are many methods in the history of the age of the year. When many students learn history, it is difficult to start with the method of age. Our country has “a long history, long years of history, many historical records, and miscellaneous stories.” For this reason, it is more necessary for us to summarize the historical events that are different from each other.
