问题

秦始皇于公元前221年灭六国,完成统一。这个年代用世纪纪年法表示是

A.公元前2世纪早期

B.公元前2世纪晚期

C.公元前3世纪早期

D.公元前3世纪晚期

答案

答案:D

题目分析:本题考察学生对世纪纪年法的认识,根据所学知识,每100年为一个世纪,具体的算法就是在给出的公元纪年上加100年,是公元前的就记作公元前多少世纪,如公元200年,加上一百年,就是记作公元3世纪,公元前200年,就记作公元前3世纪,以此类推,题目中给出的是公元前221年,加100年,就记作公元前3世纪,本题选D。

点评:本题难度适中,考察学生对纪年发的计算能力,历史上有很多纪年法,我国历史上的几种常见的纪年法有: 帝号纪年法:帝号指古代帝王或诸侯的谥号。纪年的方法就是帝号纪年。 年号纪年法:年号是封建帝王为记录在位的年代所定的名号,是皇帝继位后颁布年号用来纪年的,干支纪年法:干支是天干和地支的合称。教材中有些地方涉及到干支纪年,如“岁在甲子(指公元184年),天下大吉”,“甲午战争”(指1894年),戊戌变法(指1898年)等,就是采用干支纪年方法。还有黄帝纪年法。 民国纪年法,今天,我国采用国际通用的纪年方法是“公元纪年”。。
