高中高中历史 第三单元 法律与教化 第8课 近代西方的法律与教化课时作业 新人教版选择性必修第一册-

课时作业8 近代西方的法律与教化一、选择题1.罗马的《十二铜表法》中有这样的规定:外国人永远不能因使用而取得罗马市民财产的所有权。
由此规定可知( B )A.《十二铜表法》具有万民法性质B.《十二铜表法》保护罗马公民财产权C.《十二铜表法》保护本国所有人D.《十二铜表法》标志罗马法体系完备解析:根据材料及所学知识,A错误,因为该法为公民法,《查士丁尼民法大全》才具有民法的性质。
C错误,因为它只保护公民的利益。
D错误,罗马法体系的完成在东罗马帝国时期。
而B符合题意,故本题选B。
2.从法制发展史的角度看,某某性常常是人类幼年时代法律的共性。
古罗马所使用的大量不成文法皆依赖于神的启示和命令,其解释权掌握在祭祀手里。
而《十二铜表法》的颁布标志着成文法典的诞生。
它的问世是社会发展轨迹的浓缩,是罗马走向文明之界碑。
这表明( B )A.《十二铜表法》完全摆脱了某某性B.《十二铜表法》是公民参与立法的结果C.《十二铜表法》的解释权掌握在公民手中D.《十二铜表法》具备了现代法律的一切特征解析:结合所学知识可知,《十二铜表法》是平民和贵族斗争的结果,B选项符合题意。
《十二铜表法》是习惯法的汇编,完全摆脱某某性说法错误,A选项排除。
《十二铜表法》的解释权在贵族手里,C选项排除。
《十二铜表法》是奴隶主专制的工具,并未具备现代法律的一切特征,D选项排除。
3.《查士丁尼法学总论》和《查士丁尼学说汇纂》中都记载了罗马法学家弗罗丁斯为奴隶制与隶农制并存进行辩护的理论,“奴隶制是违反自然法的,因为人是生而自由的”,但这是“万民法的一项制度,根据万民法,一个人成为另一个人的财产”。
该材料强调( D ) A.罗马法违背了自然法B.《民法大全》侧重反对奴隶制度C.《民法大全》体系完善D.罗马法终究是一部奴隶制法典解析:由“奴隶制是违反自然法的”可知,罗马法中有关奴隶制的内容违反了自然法原理;“根据万民法,一个人成为另一个人的财产”说明罗马法又是维护奴隶制的法典,综合这两点可知,材料强调代表罗马法体系最终完成的《民法大全》违背自然法,这与它的性质密切相关,说明罗马法最终还是为了维护奴隶主利益服务的,答案为D;A项是对材料前半部分的理解,错误;B项不符合材料信息,排除;C项从材料中未能体现,排除。

Unlike many pop singers,especially those who do not write their own material,Swift has the power of turning her ideas into lyrics that will set people thinking.“Hidden beneath Taylor Swift’s not-a-girl,not-yet-a-woman sweetness is a very skillful songwriting technique,” wrote Leah Greenblatt in an American magazine.Songwriting,as Swift explains,is to cope with issues.“I tend to write about things that really impact me most.” There certainly seems to be something true and honest running through every one of the 14 songs on her album,Speak No w,about “the lessons and confusion and heartbreak and all the different things that go along with being 18,19 and 20.”“For the audience too young to have experienced real passion or heartbreak,Swift’s songs are like a potential road map,promising things will work out OK,” commented Dorian ynskey in a British newspaper.Now Swift is getting ready to go further and has so far written about 10 songs for her 2012 album,which is about feelings of growing up and becoming an adult.“They’re sad,if I’m being honest.”“They’re about my heartbreaks and my moving on.But more importantly,they are about achieving contentment.You’re not always going to be perfectly happy as you grow up.”1.What does the writer mean by saying “Werde’s words do not come from nowhere”?A.Swift stands out as a singer and songwriter.B.Only Swift writes her own songs.C.Swift begins to take interest in singing.D.Swift decides to deal with problems in her new album.2.Which of the following statements is NOT true according to the passage?A.Swift has the ability to write songs with deeper meanings.B.Swift is both enthusiastic and skillful now.C.Swift became a multi-award winner when she began to sing on the stage.D.Swift’s album Speak No w has 14 songs.3.Taylor Swift’s 2012 album mainly records________.A.dream and reality B.heartbreak and despairC.pain and growth D.problems and society4.What is the best title for the passage?A.Swift comes to people’s attentionB.Swift rises to fameC.Swift wins many awardsD.Swift experiences real passionB(2013·西安市第一次质量检测) More than half of rich Americans have not shown their full wealth to their children,a new survey showed last Tuesday.The survey,published by the Bank of America,studied the rich with $3 million or more in assets.It found that “surprisingly few of those surveyed have well-developed plans to preserve and pass on their assets to their children”.The majority of the 457 people surveyed are self-made,first-generation rich.Fifty-two percent of parents have chosen not to tell their children just how wealthy they are,and 15 percent have given away nothing about the family wealth.One in three parents said they had never thought to do it.They are worried that their children would become lazy,spend money freely,make bad decisions and even become a target for gold diggers.Only 34 percent strongly agreed that their children would be able to handle any inheritance (遗产) they plan to leave them.“There is an expectation about the wealthy parents that they have a responsibility to pass down their fortune to the next generation,”said Sallie Krawcheck,president of the Global Wealth and Investment Management of the Bank of America.“Our research,however,uncovered changing views of what one generation owes the next.”The trend is led by the world’s richest man Bill Gates,who promised in 2008 that he would leave his $58 billion fortune to the charity started by him and his wife,the Bill and Malinda Gates Foundation (基金会),and not to his children.“We want to give it back to society in the way that it will have the most positive impact,”he said.Of his plans for his children,Gates said:“I will give the kids some money but not a meaningful percentage...they will need to wo rk but they will feel reasonably taken care of.”5.We can learn from the passage that________.A.rich parents may not know how to manage their inheritanceB.rich parents don’t equal rich kids,at least in the USC.American children don’t get to inherit their parents’ wealthD.poor children don’t expect themselves to be as rich as their parents6.According to the survey,most rich Americans________.A.think they owe their children nothingB.think it best to give their money back to societyC.doubt their childr en’s ability to handle wealthD.are confident of their children’s ability to handle wealth7.The underlined word “they” in Paragraph 6 refers to________.A.responsible children B.Bill Gates and his wifeC.first-generation rich D.rich parents8.From the last paragraph,we can see that Bill Gates wants to show________.A.the trend of leaving no inheritance to childrenB.the positive impact of charity on societyC.the way of giving back to societyD.the importance of independence for children详解答案课时作业(八)Ⅰ.完形填空语篇解读:本文为夹叙夹议文。
