高三历史试题与解析-巴蜀中学2025届高考适应性月考卷(一)历史答案
历史参考答案一、选择题(本题共15小题,每小题3分,共45分。
在每小题给出的四个选项中,只有一项是符合题目要求的)题号 1 2 3 4 5 6 7 8 答案 C D C A B C B A 题号9 10 11 12 13 14 15答案 B B D C A C A【解析】1.商代方国林立,商王间接控制方国和部族即外服。
中央对地方的控制力较弱,没有形成统一的中央集权。
A、D有史实错误。
根据历史的发展,正统有以下解释:一系相承、统一全国的封建王朝;嫡系子孙;符合华夏礼仪,贯彻春秋大义的中原王朝;学派、党派等一脉相传的嫡派。
大宗是相对的,主要指嫡长子系统。
与题干“王”的称号不符。
B错误。
商代方国林立,王是商王(联盟首领)和方国首领的称谓,选择C。
2.上天为民众设立了君主,又为君主设置了辅佐,让君主行事不要过度,自天子以下的诸侯、卿大夫等各有辅佐,奖励他们的善行,匡正他们的过失。
体现了对君主的制约。
选择D。
材料阐释的是传统秩序的巩固,而不是变动。
A错误。
本题和血缘传承无关,排除B。
材料主旨是辅佐天子、诸侯等,不是分封天子、诸侯,C错误。
3.题干体现的是儒家修齐治平的思想,与C的主张一致。
A是中华文化崇尚自强不息的展现。
B是道家的道法自然。
D为墨子尚贤的主张。
4.题干中提到的“杜虎符”是一种古代的军事指挥凭证,其内容规定了只有将君主手中和将领手中的“符”合并,才能指挥超过五十人的军队。
这反映了当时对军事权力的严格控制和管理。
根据材料中提到的“必会君符,乃敢行之”,可以看出军事行动必须要得到君主的批准,这体现了君主专制权力的加强。
这是符合材料的描述。
选择A。
如果强调军事将领权重,意味着将领在军事行动中有较大的自主权。
但根据材料,将领必须等待君主的命令才能行动,所以这个选项与材料的描述不符。
B错误。
材料中并没有直接提到地方势力的问题,而且“杜虎符”的使用并不直接反映出地方势力的瓦解,所以这个选项与材料的关联性不大。
