19.B【解析】本题考查近代法国的民主政治建设，考查学生获取和解读材料信息、运用所学知识分析历史现象的能力。由材料可知，在1793年法国制宪之时，有议员提出要赋予人民审查议员和立法的权力，但这一提议最终被否定，表明当时的法国没有独立的维宪机构，故选B项；人民审查议员和立法的权力的提案被否决并不意味着主权在民原则被否定，故排除A项；根据材料无法判断君主派势力是否强大，故排除C项；这一建议被否决并不意味着当时政治派别斗争激烈，故排除D项。20.C【解析】本题考查近代德国的政治制度，考查学生获取和解读材料信息、运用所学知识分析历史现象的能力。根据材料信息可知，在德意志帝国内部，君主、各邦、议会、宰相的权力都得到体现，但又受到相应制约，这表明德意志帝国建立在历史传统和国内政治力量对比的基础之上，体现了务实精神，故选C项；以普鲁士王国为代表的各邦保留了相当大的自治权，该学者也并非只关注德意志帝国政府的权威，故排除A项；德意志帝国保留了部分历史传统，但并非只对历史传统的沿袭，故排除B项；德意志帝国带有一定的民主色彩，故排除D项。21.A【解析】本题考查美国1787年宪法，考查学生获取和解读材料信息、运用所学知识分析历史现象的能力。材料认为美国1787年宪法容纳了各种不同的利益和意见，是折中调合、妥协衡的产物，这一特征实质上是中庸原测，故选A项；B项表述片面，美国1787年宪法不但包括中央与各州的妥协，还包括大小州之间的妥协，故排除B项；C项不符合史实，故排除C项；“均衡”与史实不符，故排除D项。22.D【解析】本题考查巴黎公社的发展，考查学生获取和解读材料信息、运用所学知识分析历史现象的能力。由材料可知，巴黎公社的政治举措多是群众首倡的，这表明巴黎公社践行了人民民主，故选D项；巴黎公社并没有建立起来工农联盟，故排除A项；材料中并米体现出民主集中制，故排除B项；根据材料信息无法得出消灭了阶级剥削的结论，故排除C项。23.D【解析】本题考查冷战时期美国政策的调整，考查学生获取材料信息、运用所学知识分析历史现象的能力。据材料可知，1969年尼克松人主白宫后，便开始实行收缩战略，并且认为美国“需要一个谈判时代而不是对抗时代”，结合所学知识可知，20世纪60年代后期，由于苏联实力增强，国际局势发生变化，美国逐步走上战略收缩的道路，故选D项；20世纪60年代后期，美国综合国力下降，苏联处于攻势，故排除A项；尼克松这些主张是为了调整和苏联的关系，而非欧美关系，故排除B项；美国在冷战中的劣势地位是尼克松实行收缩政策的原因，而非结果，故排除C项。24,B【解析】本题考查世界多极化趋势，考查学生获取和解读材料信息、运用所学知识分析历史现象的能力。由材料可知，2017年欧盟国家加强军事合作，实力增强，这反映了世界多极化趋势的加强，故选B项；这一合作并不表明当时欧洲致力于推动世界和，故排除A项；欧盟的这一举动并没有扩张军队，故排除C项；从材料并不能看出欧洲地位的提升，故排除D项。25.(1)变化：君相权限逐渐明确；君相地位差距凸显；君相矛盾逐渐凸显。(2分，答出两点即可)成因：中央集权体制的建立；官僚系统的逐渐完善；君主加强专制的需要。(4分，答出两点即可)(2)因素：宰相辅国的政治传统；长治久安的现实考量；君臣共治的儒家理想；君相个人的权力欲求。(2分，答出两点即可)评价：加强了专制君主的权力；巩固了明朝政权的统治；有利于明初经济的复苏。(2分，答出两点即可)；加重了君主的负担；恶化了君臣之间的关系；埋下了皇权异化的伏笔；预示着封建制度的衰落；阻碍了中国社会的转型。(4分，答出两点即可)26.(1)历史条件：铁犁牛耕的出现；土地私有制的确立；统治者采取重农政策；思想家鼓吹小生产模式；各国变法运动的影响。(6分，答出三点即可)(2)新现象：大量种植经济作物，粮食作物种植面积遭到压缩；出现了固定种植经济作物的农户；农业生产日益专业化。(2分)影响：促进了手工业的发展；活跃了商品经济；对自然经济结构有一定的突破；一定程度上增加了农民生计的不确定性。(6分，答出三点即可)27.示例论题：近代中国选择革命而非改良的道路是由客观历史条件决定的。(2分)【高三历史·参考答案第3页（共4页）】
