选做题Ⅱ
近年来，农民收入增长减缓，中西部一些地区特别是粮食生产区甚至出现负增长。这种状况不改变，农民的积极性势必受到严重损害，农业这个基础就有动摇的危险，不仅会影响农业和农村的稳定和发展，而且会影响国民经济全局。因此，2002年3月，朱 基总理在《政府工作报告》中指出：“要把加强农业和农民收入，作为整个经济工作的突出任务，把农民是否增加收入和减轻负担，作为检验农业和农村工作的重要标准。”
请结合马克思关于扩大再生产的前提理论条件，分析论述加强农业基础地位，提高农民收入的必要性和重要性。属于液化性坏死的是A．心肌梗死B．脑梗死C．肠梗死D．肾梗死

材料一：16、17世纪时，西欧医生的地位还很低，尽管主要的宫廷医生有很高的经济收入，但医生并不被认为是一个很光荣的职业，，直到17世纪中叶，一位绅士还拒绝同一位有钱的医生的女儿结婚。律师职业虽然不被视为低等，但也不受人尊重。20世纪以后医生和律师是备受欢迎和尊重的职业。 材料二：17世纪上半叶，茶叶、咖啡等饮料进入欧美，饮茶和喝咖啡成了上层社会的时尚。18世纪时已有大量的热带水果和蔬菜进入欧洲市场，到了19世纪，比较富裕的家庭的饮食结构逐步趋向合理。 材料三：18世纪，社会底层的人民娱乐活动主要是看斗鸡、斗牛，去小酒店喝劣质的烈性酒。上层人士的消遣有打猎、赛马。赌博是各个阶层都普遍参加的活动。19世纪中叶开始，各种体育活动迅速发展起来，垒球、足球、田径运动纷纷诞生，特别是足球和田径比赛，不但吸引了许多参加者，而且吸引了更多的观众，成了各阶层人士喜爱的消遣。 ——吴于廛，齐世荣主编《世界史•近代史编》下卷 请回答 (1)从16世纪到20世纪欧洲社会发生了哪些变化？ (2)发生上述变化的原因是什么？ (3)材料表述的变化说明了什么？Theword"it"(Line3,Paragraph1)denotesA．to

Nothing has come to embody corporate greed like executive perks: the corporate jets, chauffeured limousines and country-club memberships that bosses consume in a seemingly deliberate attempt to outrage public opinion. Not for nothing bas WarrenBuffett. Omaha’s celebrated investor, named his corporate jet "The Indefensible".
The usual explanation for the perk is that it is a (rather enjoyable) way for corporate insiders to misappropriate shareholders’ money. (46) Because perks are poorly disclosed shareholders have no way of knowing when the boss is living it up at their expense. This has led to the theory that perk-laden executives are likeliest to be found in firms with lots of cash. but few investment prospects.
But in a recent paper, Raghuram Rajah, the IMF’s chief economist, and Julie Wulf, of the Wharton School, looked at how more than 300 big companies dished out perks to their executives in 1986-99. (47) It turns out that neither cash-rich, low-growth firms nor firms with weak governance shower their executives with unusually generous perks. The authors diD、however, find evidence to support two competing explanations.
(48) First firms in the sample with more hierarchical organisations lavished more perks on their executives than firms with flatter structures. Why Perks are a cheap way to demonstrate stares. Just as the armed forces ration medals, firms ration the distribution of conspicuous symbols of corporate status. Second, perks are a cheap way to boost executive productivity. (49) Firms based in places where it takes a long time to commute are more likely to give the boss a chauffeured limousine. Firms located far from large airports are likelier to lay on a corporate jet.
So there it is. The boss needs his luxury pad on FifthAvenue and his chauffeured stretch-limo because he might otherwise do less work. (50) Making it harder for the boss to consume conspicuously risks dangerous anarchy as, bereft of its symbols of corporate status, the firm’s hierarchy collapses into a muddled heap. Perhaps, in light of these findings, Mr.Buffett should call his next jet "The Indispensable".唾液中除含有淀粉酶外，还有A．肽酶B．蛋白水解酶C．溶菌酶D．凝乳酶E．寡糖酶
