周测卷二十生产工具与劳作方式1.D由材料中“18世纪”“而与15、16世纪一文艺复兴的世纪靠得更近的世纪”等信息可知，该引言所表达的观，点侧重于强调不同世纪的文化成果。结合所学知识可知，18世纪，启蒙运动盛行，其思想核心为理性主义，故答案为D项。生产方式革新不属于文化成果，排除A项；18世纪，资产阶级统治尚未确立，排除B项；C项反映的是文艺复兴运动，排除。2.C根据材料信息并结合所学知识可知，在两次工业革命的推动下，欧洲主要资本主义国家的主要城市人口数量迅速增加，但各国的人口数量增长速度明显不同，其中德国人口数量增长速度最快，这说明欧洲主要资本主义国家的经济发展并不均衡，故答案为C项。A项在材料中体现不出，材料只反映了欧洲主要资本主义国家主要城市的人口增加，无法反映这些国家全国的人口增加状况，排除A项；B项在材料中体现不出，排除；垄断组织是第二次科技革命的产物，与材料时间不符，排除D项。3.D由材料中两组农具并结合所学知识可知，图2中的农具为曲辕犁，这种犁具的进步性体现在它节省了畜力，操作灵活，故答案为D项。使用畜力进行犁耕时，需要人的操作，排除A项；曲辕犁只能使操作简单灵活，不能保证高产，排除B项；曲辕犁省力即可省时，而不是费时，排除C项。4.A由材料“六个纺工才能供应一个织工所需的棉纱”可知，飞梭的出现客观上刺激了纺纱技术的发展，进而引发了纺织业领域中相关技术和设备的革新，故答案为A项。B项在材料中体现不出，排除；飞梭的发明只是工业革命的前奏，此时工业革命尚未正式开始，排除C项；D项不符合材料主旨，排除。5.C根据材料“需要寻求新的动力形式”并结合所学知识可知，这种新的动力形式指的是不同于蒸汽动力的新能源，即电力，而电的发明得益于电磁理论的提出，即近代科学理论的发展，故答案为C项。蒸汽革命已经改变了人类社会的经济结构，排除A项；世界市场的初步形成是第一次工业革命的结果，排除B项；人类交通进入立体时代的标志是飞机的发明和应用，排除D项。6.B由材料中化学工业和钢铁工业的发展状况可知，第二次工业革命的特点是科技与生产紧密结合，故答案为B项。材料无法体现科学理论转化为生产力的时间缩短，排除A项；C项对材料解读片面，排除；第二次工业革命使重工业的主导地位确立，但这在材料中体现不出，排除D项。7.C由材料中“官办工业”“洋务运动”等信息可知，这些新式企业虽然为官办性质的企业，但它们蕴含了机器大生产的近代化因素，因此这一“复兴”的实质是近代生产方式的传播，故答案为C项。A项不符合材料主旨，排除；此时自然经济仍然占据主导地位，排除B项；民族资本主义诞生的标志是民族资本家创办的企业诞生，排除D项。8.B根据材料可知，在英国举办第一届世界博览会期间，很多工厂和公司以不同形式鼓励工人参观展览，这是给工人补贴福利、缓和矛盾的表现，这从侧面反映出当时的阶级矛盾尖锐，故答案为B项。A项在材料中没有体现，排除；当时还没有建立起社会福利制度，排除C项；材料反映的不是资产阶级代议制的完善，排除D项。·57【23·G3ZCJ(新教材老高考)·历史·参考答案一R一必老一QG】
