学者龙太江在《论政治妥协：以价值为中心的分析》中指出：第一，美国宪法所设定的政治体制本身就是一种重要的政治妥协机制；第二，从宪法的产生过程来看，它是一个多元利益相互妥协的产物；第三，从宪政发展过程来看，许多关键性的、重大的问题往往是通过政治妥协缓解并进而一步步解决的。对美国宪政发展表现出的政治妥协理解错误的是(  )

    元澹，字行冲，以字显，后魏常山王素莲之后。少孤，养于外祖司农卿韦机。及长，博学，尤通故训。及进士第，累迁通事舍人。狄仁杰器之。尝谓仁杰曰：“下之事上，譬富家储积以自资也，脯腊膎胰以供滋膳，参术芝桂以防疾疢。门下充旨味者多矣，愿以小人备一药石，可乎？”仁杰笑曰：“君正吾药笼中物，不可一日无也。”

    景云中，授太常少卿。行冲以系出拓拔，恨史无编年，乃撰《魏典》三十篇，事详文约，学者尚之。初，魏明帝时，河西柳谷出石，有牛继马之象。魏收以晋元帝乃牛氏子冒司马姓，以著石符。行冲谓昭成皇帝名犍，继晋受命，独此可以当之。有人破古冢得铜器，似琵琶，身正圆，人莫能辨。行冲曰：“此阮咸所作器也。”命易以木，弦之，其声亮雅，乐家遂谓之“阮咸”。

    开元初，罢太子詹事，出为岐州刺史，兼关内按察使。自以书生，非弹治才，固辞。入为右散骑常侍、东都副留守。嗣彭王子志谦坐仇人告变，考讯自诬，株蔓数十人，行冲察其枉，列奏见原。四迁大理卿，不乐法家，固谢所居官，改左散骑常侍，封常山县公。充使检校集贤，再迁太子宾客、弘文馆学士。先是，马怀素撰书志，褚无量校丽正四部书，业未卒，相次物故。诏行冲并代之。玄宗自注《孝经》， 诏行冲为疏，立于学官。以老罢丽正校书事。

    初，魏光乘请用魏征《类礼》列于经，帝命行冲与诸儒集义作疏，将立之学，乃引国子博士范行恭、四门助教施敬本采获刊缀为五十篇，上于官。于是右丞相张说建言：“戴圣所录，向已千载，与经并立，不可罢。魏孙炎始因旧书擿类相比，有如钞缀，诸儒共非之。至征更加整次，乃为训注，恐不可用。”帝然之，书留中不出。行冲意诸儒间己，因著论自辩。俄丐致仕，十七年卒，年七十七，赠礼部尚书，谥曰献。

    It's true that “A small change can make a big difference” in our life. A better technical term that can well 1 this idea is the “Butterfly Effect”. A butterfly's 2 wings can make changes in the path of a tornado; it may  3  create or prevent a tornado at a certain location.

    The “Butterfly Effect” plays a role in our  4  to a great extent. Small  5  could make a huge difference in our relationships. Most of the time we take things for granted in our  6 relations. We don't even think of saying “Thank You” to our parents as we  7 they are supposed to do things for us. Understanding some of the subtle（细腻的）feelings of our loved ones and  8 them the way they need would  9 change the relationship into a stronger one. I've come across people who feel  10 in their relationships as they  11 to address these small needs.

    The “Butterfly Effect” also plays a role in our work. Looking  12 into the smallest details while starting a 13 is critical. A subtle mistake while taking care of our customer's  14 could end up creating big trouble at the end of the process. This would mean a huge expense to  15 at the final delivery stage.

    Every morning, the time it takes me to  16 to my office depends on what time I start from my home. It usually takes 30 minutes if I start at 7:20 am. It takes more than a(n)  17 if I start at 7:30 am. At first I was  18 how just a 10-minute difference initially could add more than 30 minutes to the journey.  19 , the number of vehicles that come out on the road increases more than twice due to that 10-minute  20 and it looks like butterflies crowding on the road. Yes, this is nothing but the “Butterfly Effect”.
