2.媒体常说食品(或任何个别商品)的价格上涨是通货膨胀的原因。
试用货币供给与需求决定物价水平的理论,来评论前述结论。
3. “中央银行决定利率”与“借贷市场决定利率”两种说法,究竟何者正确?4.党政府支出(G )永久增加,同时定额税(lump sum tax )也增加时,a )若G 是可以替代个人消费(例如公园)时,GDP 会如何变化?b )若G 是有生产性(例如有助于生产的公共服务)时,GDP 会如何变化?育明解析:1.答:t期投资It=KD.t-K.t-1(1-d),KD为意愿资本存量,d为折旧。
而MPK(K)-d=1+r,r为实际利率,证明略,使该式成立的K即为意愿资本存量KD。
MPK上升,意味着资本K上升才能使上式成立,意愿资本存量KD 上升,投资需求上升。
MPK下降同样论述。
事实上MPK的变动,使得投资需求线I(r)发生平行移动。
2.答:该说法不恰当。
货币需求方程M=P*L(R,Y)R为名义利率,Y为产出。
猪肉价格上涨不影响生产Y,因猪肉是可替代品。
故也不影响商品市场出清,不影响r, R。
而货币供给M给定,故不影响价格水平P,从而肉价上涨不会导致通货膨胀。
现实中通胀是因为,**爱民为稳定社会而发行货币进行补贴,使M增加才有通胀。

3.单选题The belief that the mind plays an important role in physical illness goes back to the earliest days of medicine. From the time of the ancient Greeks to the beginning of the 20th century, it was generally accepted by both physician and patient that the mind can affect the course of illness, and it seemed natural to apply this concept in medical treatments of disease. After the discovery of antibiotics, a new assumption arose that treatment of infectious or inflammatory disease requires only the elimination of the foreign organism or agent that triggers the illness. In the rush to discover antibiotics and drugs that cure specific infections and diseases, the fact that the bod y’s own responses can influence susceptibility to disease and- its course was largely ignored by medical researchers.It is ironic that research into infectious and inflammatory disease first led 20th-century medicine to reject the idea that the mind influences physical illness, and now research in the same field — including the work of our laboratories and of our collaborators at the National Institutes of Health 一 is proving the contrary. New molecular and pharmacological tools have made it possible for us to identify the intricate network that exists between the immune system and the brain,a network that allows the two systems to signal each other continuously and rapidly. Chemicals produced by immune cells signal the brain, and the brain in turn sends chemical signals to restrain the immune system. These same chemical signals also affect behavior and the response to stress. Disruption of this communication network in any way, whether inherited or through drugs, toxic substances or surgery, exacerbates the diseases that these systems guard against: infectious, inflammatory, autoimmune, and associated mood disorders.The clinical significance of these findings is likely to prove profound. They hold the promise of extending the range of therapeutic treatments available for various disorders, as drugs previously known to work primarily for nervous system problems are shown to be effective against immune maladies, and vice versa. They also help to substantiate the popularly held impression (still discounted in some medical circles) that our state of mind can influence how well we resist or recover from infectious or inflammatory diseases.The brain’s stress response system is activated in threatening situations. The immune system responds automatically to pathogens and foreign molecules. These two response systems are the body’s principal means for maintaining an internal steady state called homeostasis. A substantial proportion of human cellular machinery is dedicated to maintaining it.When homeostasis is disturbed or threatened, a repertoire of molecular, cellular and behavioral responses comes into play. These responses attempt to counteract the disturbing forces in order to reestablish a steady state. They can be specific to the foreign invader or a particular stress, or they can be generalized and nonspecific when the threat to homeostasis exceeds a certain threshold. The adaptive response may themselves turn intostressors capable of producing disease. We are just beginning to understand the interdependence of the brain and the immune system, how they help to regulate and counter-regulate each other and how they themselves can malfunction and produce disease.1.The passage supplies information to suggest that ()2.Which of the following best states the mind-body interaction in disease?3.Which of the following statements about clinical significance of the new findings can be bestsupported by the passage?4.Which of the following statements can be inferred from the passage?5.According to the passage, in order to maintain an internal steady state called homeostasis,().问题1选项A.it has always been the belief of both physician and patient that one’s state of mind can affectphysical diseaseB.the popular belief that stress exacerbates inflammatory illness has always been discredited by thedoctorsC.the discovery of antibiotics sheds light on people’s understanding of the mind-body interaction indiseaseD.there is a new understanding of the communication between the brain and immune system问题2选项A.The brain and immune systems send signals to each other.B.The immune and central nervous systems are organized in very different ways to affect thecourse of illness.C.Disruption of the communication of the brain and immune system can cure certain disease.D.The immune system and the brain share a lot of hormones to facilitate their communication. 问题3选项A.The responsiveness to stress is genetically determined.B.The treatment of immune maladies can be consciously controlled.C.Psychoactive drugs may in some cases be used to treat inflammatory diseases.D.Social interactions can lessen psychological stress and alter immune responses.问题4选项A.Taking the cure at a mountain sanatorium doesn’t work for the treatment for many chronicdiseases.B.The relaxing effects of hot-springs spa can help restore the communication between the brain andimmune system.C.The disruption of the brain’s stress response reduces the body’s response.D.Depression is also associated with inflammatory disease.问题5选项A.sometimes the stress response needs to go to the extremeB.the stress response has to bar the foreign pathogens from the bodyC.both the stress and immune responses need to be regulatedD.the immune system promotes physiological and behavioral changes【答案】第1题:D第2题:A第3题:C第4题:D第5题:B【解析】1.主旨题。
北京大学CCER 中微作业习题及答案讲解Homework1,Feb.20,2009(Chapters 2and 3)1.有两种商品x1和x2,价格分别为p1和p2,一个消费者的收入为m 。
当11x x 时,政府加从量税t,画出预算集并写出预算线.2.消费者消费两种商品(x1,x2),如果花同样多的钱可以买(4,6)或(12,2),写出预算线的表达式。
3.描述中国粮价改革.(1)假设没有任何市场干预,中国的粮价为每斤0.4元,每人收入为100元。
把粮食消费量计为x ,在其它商品上的开支为y ,写出预算线,并画图。
(2)假设每人得到30斤粮票,可以凭票以0.2元的价格买粮食,再写预算约束,画图。
(3)假设取消粮票,补贴每人6元钱,写预算约束并画图。
证明两条无差异曲线不能相交。
画出一元纸币(x1)和五元纸币(x2)的无差异曲线,计算边际替代率。
两种商品中,假定商品1为中性商品,即消费多少不会使消费者更高兴或者更不高兴,商品2为消费者喜欢的商品(good ),画出无差异曲线,计算边际替代率。
复习方法如果细心对比一下历年的专业课考题,我们就会发现考研专业课考试的重复性很强,虽然题量和题型可能会有一些的改动,但是每年考试的命题重点基本上不会有太大的变化。
所以要想在专业课的竞争中获得胜利,建议广大考生第一步就是要搜集专业课历年考试资料和最新信息,标准就是要“准”和“全”。
第一,有效地收集专业课辅导资料专业课的资料主要包括专业辅导书、课程笔记、三人行辅导班笔记以及最重要的历年试题。
如果这些都搜集全的话,就可以踏踏实实的开始复习了。
专业辅导书是复习的出发点,所有的考试的内容都是来源如此,但是通常专业辅导书都是又多又厚的,所以要使我们复习的效率最大化,就要运用笔记和历年试题把书本读薄。
如前所述,专业课试题的重点基本上不会有太大的变动,所以仔细研究历年试题可以帮助我们更快的掌握出题点和命题思路,并根据这些重点有的放矢的进行复习,这样可以节省很多复习的时间。
