【分析解答题】下面是一组有关中国革命政权的材料: 材料1 中华苏维埃第一次全国代表大会谨向全世界与全中国的劳动群众宣布它要在全中国所实现的基本任务,即中华苏维埃共和国的宪法大纲。 这些任务,在现在的苏维埃区域内,已经开始实现。但中华苏维埃第一次全国人民代表大会认为这些任务的全部完成,只有在打倒帝国主义和国民党在全中国的统治,在全中国建立苏维埃共和国的统治之后。而且在那时中华苏维埃共和国的宪法大纲才能具体化,而成为详细的中华苏维埃共和国的宪法。中华苏维埃全国代表大会,号召全中国的工农劳动群众,在中央苏维埃共和国临时政府的指导之下,为这些任务在全中国的实现而奋斗。 (一)中华苏维埃共和国的根本法(宪法)的任务,在于保证苏维埃区域工农民主专政的政权和达到它在全中国的胜利。这个专政的目的,是在消灭一切封建残余,赶走帝国主义列强在华的势力,统一中国,有系统地制止资本主义的发展,进行国家的经济建设,提高无产阶级的团结与觉悟程度,团结广大的贫农群众在它的周围,以转变到无产阶级专政。 (二)中华苏维埃政权所建立的是工人和农民的民主专政的国家。苏维埃全部政权是属于工人、农民、红军,士兵及一切劳苦民众,所有工人、农民、红军、兵士及一切劳苦民众都有权选派代表参与政权的管理。只有军阀、官僚、地主;豪绅、资本家、富农、僧侣及一切剥削人的人和反革命分子是没有选派代表参加政权和政治上自由的权利的。 (三)中华苏维埃政权以消灭封建制度及彻底地改善农民生活为目的,颁布土地法,主张没收地主阶级的土地,分配给贫农、中农,并以实现土地国有为目的。 ——摘自《中华苏维埃共和国宪法大纲》(1931年11月7日通过) 材料2 为了进一步巩固边区,发展抗日的政治经济文化建设,以达到坚持长期抗战增进人民福利之目的起见,中共陕甘宁边区中央局特于边区第二届参议会举行选举之际,根据孙中山先生的三民主义,总理遗嘱及中共中央的抗日民族统一战线的原则,向我边区二百万人民提出如下之纲领,如共产党当选为行政人员时,即将照此纲领坚决实施之。 (一)团结边区内部各社会阶级、各抗日党派,发挥一切人力、物力、财力、智力,为保卫边区、保卫西北、保卫中国、驱逐日本帝国主义而战。 (二)坚持与边区境外友党、友军及全体人民的团结,反对投降、分裂、倒退行为。 (三)本党愿与各党各派及一切群众团体进行选举联盟,并在候选名单中确定共产党只占三分之一,以便各党各派及无党无派人士均能参加边区民意机关之活动与边区行政之管理,在共产党员被选为某一行政机关之主管人员时,应保证该机关之职员有三分之二为党外人士充任,共产党员应与这些党外人士实行民主合作,不得一意孤行,把持包办。 (四)在土地已经分配区域,保证一切取得土地的农民之私有土地制。在土地未经分配区域,保证地主的土地所有权及债主的债权,惟须减低佃农租额及债务利息,佃农则向地主缴纳一定的租额,债务人员须向债主缴纳一定的利息,政府对租佃关系与债务关系加以合理的调整。 ——摘自《陕甘宁边区施政纲领》(1941年5月1日提出) 材料3 资产阶级的共和国,外国有过的,中国不能有,因为中国是帝国主义压迫的国家。惟一的出路是经过工人阶级领导的人民共和国。 人民是什么 在中国,在现阶段,是工人阶级、农民阶级,是城市小资产阶级和民族资产阶级。这些阶级在工人阶级和共产党的领导之下,团结起来,组成自己的国家,选举自己的政府,向着帝国主义的走狗即地主阶级和官僚资产阶级以及代表这些阶级的国民党反动派及其帮凶们实行专政,实行独立,压迫这些人,只许他们规规矩矩,不许他们乱说乱动。如果要乱说乱动,立即取缔,予以制裁。对于人民内部,则实行民主制度,人民有言论集会结杜等项的自由权。选举权,只给人民,不给反动派。这两方面,对人民内部的民主和对反动派的专政方面,互相结合起来,就是人民民主专政”。 ——摘自毛泽东:《论人民民主专政》(1949年6月30日) 请回答: (1)比较材料1、2,抗日民主政府与工农民主政府相比发生了哪些重要变化 为什么会发生这些变化(2)比较材料1、3,指出人民民主专政与工农民主专政的联系和区别。 (3)如何理解材料3中的“资产阶级共和国,外国有过的,中国不能有,因为中国是帝国主义压迫国家。惟一的出路是经过工人阶级领导的人民共和国”。请结合有关史实说明。
【分析解答题】Economists often like to speak of Homo economicus—rational economic man. In practice, human economic behaviour is not quite as rational as the relentless logic of theoretical economics suggests it ought to be. When buying things in a straight exchange of money for goods, people often respond to changes in price in exactly the way that theoretical economics predicts.But when faced with an exchange whose outcome is predictable only on average, most people prefer to avoid the risk of making a loss than to take the chance of making a gain in circumstances when the average expected outcome of the two actions would be the same.
There has been a lot of discussion about this discrepancy in the economic literature—in particular, about whether it is the product of cultural experience or is a reflection of a deeper biological phenomenon. So KeithChen, of the Yale School of Management, and his colleagues decided to investigate its evolutionary past. They reasoned that if they could find similar behaviour in another species of primate (none of which has yet invented a cash economy) this would suggest that loss aversion evolved in a common ancestor. They chose the capuchin monkey,Cebus apella, a SouthAmerican species often used for behavioral experiments.
First, the researchers had to introduce their monkeys to the idea of a cash economy. They did this by giving them small metal discs while showing them fooD、The monkeys quickly learned that humans valued these inedible discs so much that they were willing to trade them for scrumptious pieces of apple, grapes and jelly. Preliminary experiments established the amount of apple that was valued as much as either a grape or a cube of jelly, and set the price accordingly, at one disc per food item. The monkeys were then given 12 discs and allowed to trade them one at a time for whichever foodstuff they preferreD、
Once the price had been established, though, it was changeD、The size of the apple portions was doubled, effectively halving the price of apple.At the same time, the number of discs a monkey was given to spend fell from 12 to nine. The result was that apple consumption went up in exactly the way that price theory (as applied to humans) would predict. Indeed, averaged over the course of ten sessions it was within 1% of the theory’s prediction. One up toCebus economicus.
The experimenters then began to test their animals’ risk aversion. They did this by offering them three different trading regimes in succession.Each required choosing between the wares of two experimental “salesmen”. In the first regime one salesman offered one piece of apple for a disc, while the other offered two. However, half the time the second salesman only handed over one piece.Despite this deception, the monkeys quickly worked out that the second salesman offered the better overall deal, and came to prefer him.
21. The capuchin monkey was chosen for the experiments because____________
[A] it is from SouthAmericA、
[B] it doesn’t understand the concept of money.
[C] it is often used in behavioral experiments.
[D] it is cute and friendly.

[A] see if the monkeys would “buy” more apples, as humans woulD、
[B] see if the monkeys understood the idea of a cash economy.
[C] see if the monkeys preferred apples or another kind of fooD、
[D] see what the monkeys would buy with only nine metal discs.

[A] monkeys don’t mind being deceiveD、
[B] monkeys like to take risks.
[C] monkeys don’t really understand the concept of a cash economy.
