Most American families are smaller than the families in other countries. They have one or two parents and one or two children. Children in the US will leave their parents’ home when they grow up. They usually live far from their parents because they want to find good jobs. They often write to their parents or telephone them. And they often go to visit their parents on holiday. Parents usually let their children choose their own jobs. Americans think it important for young people to decide their lives by themselves. Children are asked to do some work around their house.

(12分)宪政是学术界的热门术语,中国学术界对它的推崇和研究可谓炙手可热,其势头直追百年前的宪政风潮。阅读材料,回答下列要求:

材料一 世界之政有两种:一曰有宪法之政(亦名立宪之政),二曰无宪法之政(亦名专制之政)。采一定之政治以治国民谓之政体。世界之政体有三种:一曰君主专制政体,二曰君主立宪政体,三曰民主立宪政体。今日全地球号称强国者十数,除俄罗斯为君主专制政体,美利坚、法兰西为民主立宪政体外,自余各国则皆君主立宪政体也。君主立宪者,政体之最良也……立宪政体,亦名为有限权之政体;专制政体,亦名为无限权之政体。有限权云者,君有君之权,权有限;官有官之权,权有限;民有民之权,权有限。故各国宪法,皆首言君主统治之大权及皇位继袭之典例,明君之权限也;次言政府及地方政治之职分,明官之权限也;次言议会职分及人民自由之事件,明民之权限也……不知君权有限云者,非臣民限之,而宪法限之也……是故欲君权之有限也,不可不用民权;欲官权之有限也,更不可不用民权。宪法与民权,二者不可相离,此实不易之理,而万国所经验而得之也。

——摘自梁启超《立宪法议》

材料二 清政府最终决定“预备立宪”是资产阶级立宪派长期斗争的结果……以慈禧为首的最高统治者为了维护统治集团的最高利益,为了消弭革命,为了笼络立宪派士人和实力派官员,宣布预备立宪……1908年8月,清政府颁布了具有君主立宪国家宪法性质的文献——《钦定宪法大纲》,包括附件在内总共有40条。尽管《钦定宪法大纲》的核心是强调君主具有至高无上的权力,但却不能不以法律的形式规定了臣民的权利。此外,还规定了议院、选举方面的内容,确定立宪预备期为9年。无论如何,《钦定宪法大纲》含有资产阶级宪政的性质,不能不说是一个历史性的进步……

——摘自杨宁一主编《历史学习新视野新知识》

材料三  1911年在中国建立起美国政体的仿制品,真是荒唐可笑。……这种政体悲惨地结束了,即悲惨地失败了。然而,失败的并不是这种政体,而是一代人。

——摘自N.佩弗《远东》

根据材料并结合所学知识,以近代中西政体为例,谈谈你对“宪政”的理解。(要求:观点明确、史论结合、思路开阔、逻辑严谨)
