宏观经济学思考题及参考答案

宏观经济学思考题及参考答案（1）第四章基本概念：潜在GDP，总供给，总需求，AS曲线，AD曲线。思考题 1、宏观经济学的主要目标是什么?写出每个主要目标的简短定义。请详细解释为什么每一个目标都十分重要。答:宏观经济学目标主要有四个:充分就业、物价稳定、经济增长和国际收支平衡。（1)充分就业的本义是指所有资源得到充分利用，目前主要用人力资源作为充分就业的标准;充分就业本不是指百分之百的就业，一般地说充分就业允许的失业范畴为4%。只有经济实现了充分就业，一国经济才能生产出潜在的GDP，从而使一国拥有更多的收入用于提高一国的福利水平。（2）物价稳定，即把通胀率维持在低而稳定的水平上。物价稳定是指一般物价水平(即总物价水平)的稳定;物价稳定并不是指通货膨胀率为零的状态，而是维持一种能为社会所接受的低而稳定的通货膨胀率的经济状态，一般指通货膨胀率为百分之十以下。物价稳定可以防止经济的剧烈波动，防止各种扭曲对经济造成负面影响。 (3)经济增长是指保持合意的经济增长率。经济增长是指单纯的生产增长，经济增长率并不是越高越好，经济增长的同时必须带来经济发展;经济增长率一般是用实际国民生产总值的年平均增长率来衡量的。只有经济不断的增长，才能满足人类无限的欲望。（4)国际收支平衡是指国际收支既无赤字又无盈余的状态。国际收支平衡是一国对外经济目标，必须注意和国内目标的配合使用;正确处理国内目标与国际目标的矛盾。在开放经济下，一国与他国来往日益密切，保持国际收支的基本平衡，才能使一国避免受到他国经济波动带来的负面影响。 3，题略答:a.石油价格大幅度上涨，作为一种不利的供给冲击，将会使增加企业的生产成本，从而使总供给减少，总供给曲线AS将向左上方移动。 b.一项削减国防开支的裁军协议，而与此同时，政府没有采取减税或者增加政府支出的政策，则将减少一国的总需求水平，从而使总需求曲线AD向左下方移动。 c.潜在产出水平的增加，将有效提高一国所能生产出的商品和劳务水平，从而使总供给曲线AS向右下方移动。 d.放松银根使得利率降低，这将有效刺激经济中的投资需求等，从而使总需求增加，总需求曲线AD向右上方移动。第五章基本概念：GDP，名义GDP，实际GDP，NDP，DI，CPI，PPI。思考题： 5.为什么下列各项不被计入美国的GDP之中? a优秀的厨师在自己家里烹制膳食; b购买一块土地; c购买一幅伦勃朗的绘画真品; d某人在2009年播放一张2005年录制的CD所获得的价值; e电力公司排放的污染物对房屋和庄稼的损害;

(完整版)英语连词知识点总结

英语连词知识点总结一、并列连词并列连词用来连接平行对等（即互不从属）的词、词组或分句。按照并列连词在句子中的作用可分为：并列关系，转折关系，选择关系，因果关系。基本并列连词如and, or , but , 关联连词如either...or , neither...nor , not only...but also,both ...and, whether...or 等；介于并列连词与从属连词或介词之间的结构如 as well as , as much as, rather than , more than, no less than 等；此外还有些'半连接词'，一些语法学家把它们称为连接副词，如 nevertheless, however, meanwhile, otherwise, likewise 等，在句中做连接性状语。这类连词主要是从逻辑上，而不是从形式上连接句子，其关系比较松散。并列关系的连词有：and, both…and, not only…but also, as well as, and…as well, not…nor, neither…nor等。 1.and的基本用法是表示并列和对称关系。例4 He sang and played the guitar. 他一边唱歌一边弹吉他。（1）两个对等的宾语或状语之间，在肯定句中用and，但在否定句中，不用and，一般用or或nor。例5 Our college is not in Beijing or Shanghai. 我们的学院既不在北京也不在上海。（2）当一个句子中出现了两个否定词时，应该用and连接并列成分。这时and表示的也是全部否定。例6 He did not talk loudly and also not clearly. 他说话声音不大，也不清晰。（3）and用来连接条件分句和结果分句，意思是“……，那么……”。当两个并列成分本身都是否定时，也要用and连接，and在这种情况下，仍然表示全部否定。（4）在come, go, run, hurry up, stay, stop等动词后，and能用来代替省略to不定式引导的目的状语。例7 Would you go and tell the children to shut up? 你能告诉孩子们别再说话了吗？注：有时and后可用第三人称单数或过去式。例8 He went and had a drink with us yesterday. 昨天他来了，和我们喝了点酒。用在try, wait等后，也有类似的用法，但只能用它们的原形。例9 Try and get some water. 尽量拿点水来。（5）祈使句 + and 表示结果。例10 Let’s give him some help, and he will be able to improve in his studies. 咱们帮帮他，他一定会提高他的学习成绩。（6）and that ( or those)…，……而且……其作用是补充前面所说的话，以达到强调的目的。用来代表前一分句的全部或一部分。例11 He speaks English, and that very well. 他会说英语，而且说的很好。（7）at once… and …既……又…… 例12 The novel is at once interesting and instructive. 那部小说既有趣，又有教育意义。 2. both …and连接两个平等的成分，避免用两个以上的平等的成分。例13 A man should have both courage and perseverance. 一个人应该既有勇气又有毅力。 3. not only… but also…有时but或also可省略，not only位于句首要倒装。例14 He is not only handsome but also clever. 他不仅英俊潇洒，而且聪明。 4. as well as相当于连词，其意为in addition to ，and also，besides等。as well as的侧重点在前，强调语气较强。连接两个名词时，谓语动词要与第一个名词相一致。例15 He as well as I agrees with you. 他和我一样都同意你的观点。例16 His parents as well as he are very kind to me. 他的父母和他都对我很好。 5. neither…nor…它们可单独使用，位于句首时要倒装。

A．that B．where C．which D．whose 【答案】B 【解析】试题分析：考查定语从句：句意：Stephen Hawking认为地球不可能是生命逐渐发展的唯一星球。先行词是the only planet，定语从句缺少地点状语，用where引导定语从句，选B. 考点：考查定语从句 2．I’m sorry I got caught in the traffic；_________, I could have been here sooner．A．besides B．although C．anyway D．otherwise 【答案】D 【解析】考查含蓄虚拟条件句。I could have been here sooner是和过去事实相反的虚拟语气，四个选项中只有otherwise可以充当含蓄虚拟条件，相当于if I had not got caught in the traffic.所以选D。 3．_____ astronauts cannot go to a baseball game or a movie in space, there are many familiar activities that they can still enjoy. A．Once B．Unless C．While D．Since 【答案】C 【解析】 while在此句中作为连词，表让步，意思是“虽然，尽管”。句意：在太空中，宇航员们虽然不能去看棒球比赛或看电影，但那里还有很多相类似的活动他们仍然是可以玩的。考点：连词／连接词 4．The position, however, ____ you are applying, is not quite a well-paid one. A．that B．which C．for which D．to which 【答案】C 【解析】 C 考查非限制性定语从句。However为插入语，先行词为The position，定语从句中的短语apply for意为申请，所以应填for whiCh，此时whiCh做apply for的宾语。故选C。 5．Life isn’t always beautiful, ________ the struggles make you stronger and the changes make

思考题与习题答案

思考题与习题 1 1- 1 回答以下问题： ( 1)半导体材料具有哪些主要特性？ (2) 分析杂质半导体中多数载流子和少数载流子的来源； (3) P 型半导体中空穴的数量远多于自由电子， N 型半导体中自由电子的数量远多于空穴，为什么它们对外却都呈电中性？ (4) 已知温度为15C 时，PN 结的反向饱和电流 I s 10 A 。当温度为35 C 时，该PN 结的反向饱和电流I s 大约为多大？ ( 5)试比较二极管在 Q 点处直流电阻和交流电阻的大小。解： ( 1)半导体的导电能力会随着温度、光照的变化或掺入杂质浓度的多少而发生显着改变，即半导体具有热敏特性、光敏特性和掺杂特性。 ( 2)杂质半导体中的多数载流子是由杂质原子提供的，例如供一个自由电子，P 型半导体中一个杂质原子提供一个空穴，浓度；少数载流子则是由热激发产生的。 (3) 尽管P 型半导体中空穴浓度远大于自由电子浓度，但 P 型半导体中，掺杂的杂质原子因获得一个价电子而变成带负电的杂质离子(但不能移动)，价电子离开后的空位变成了空穴，两者的电量相互抵消，杂质半导体从总体上来说仍是电中性的。同理， N 型半导体中虽然自由电子浓度远大于空穴浓度，但 N 型半导体也是电中性的。 (4) 由于温度每升高10 C ，PN 结的反向饱和电流约增大 1倍，因此温度为 35C 时，反向饱和电流为 (5) 二极管在 Q 点处的直流电阻为交流电阻为式中U D 为二极管两端的直流电压， U D U on ，I D 为二极管上流过的直流电流， U T 为温度的电压当量，常温下 U T 26mV ，可见 r d R D 。 1- 2 理想二极管组成的电路如题 1- 2图所示。试判断图中二极管是导通还是截止，并确定各电路的输出电压。解理想二极管导通时的正向压降为零，截止时的反向电流为零。本题应首先判断二极管的工作状态，再进一步求解输出电压。二极管工作状态的一般判断方法是：断开二极管，求解其端口电压；若该电压使二极管正偏，则导通；若反偏，则截止。当电路中有两只或两只以上二极管时，可分别应用该方法判断每只二极管的工作状态。需要注意的是，当多只二极管的阳极相连 (共阳极接法)时，阴极电位最低的管子将优先导通；同理，当多只二极管的阴极相连(共阴极接法) 时，阳极电位最高的管子将优先导通。 (a) 断开二极管 D ，阳极电位为12V ，阴极电位为6V ，故导通。输岀电压 U O 12V 。 (b) 断开二极管 D 1、D 2, D 1、D 2为共阴极接法，其阴极电位均为 6V ，而D 1的阳极电位为9V ， D 2的阳极电位为5V ,故D 1优先导通，将 D 2的阴极电位钳制在 7.5V ，D 2因反向偏置而截止。输岀电压 U O 7.5V 。 N 型半导体中一个杂质原子提因此多子浓度约等于所掺入的杂质 P 型半导体本身不带电。因为在

中考英语连词知识点总结

中考英语连词知识点总结 2016年中考英语连词知识点总结连词是一种虚词，不能担任一个句子成分。连词在句中主要起连接词与词、短语与短语及句子和句子的作用。它主要是包括并列连词和从属连词。 1、并列连词and和or： ①and和or是用得最多的并列连词，可以连接： a.两个并列的动词：Weweresinginganddancingallevening.整个晚上我们都在唱歌跳舞。 b.名词、形容词等： Thisappleisbigandred.Wouldyoulikefishorbeef? c.两个并列的.分句(句子)：IsaiditandImeantit.我说话算数。 ②and可连接两个分句，表示递进关系。Givehimaninchandhewilltakeamile.他会得寸进尺。 ③or可连接分句，表示"否则"： Don'tdrivesofastoryou'llhaveanaccident.别开这么快，不然你会出车祸。 2、表示意思转折的连词：but,yet: ①but和yet的用法： Theweatherwillbesunnybutcold.天气会晴朗但很冷。 Itisstrange,yettrue.这很奇怪，却是真的。

②however,still等为副词，但可起连接作用，表示意思的转折 ---"但是"或"然而"。 a.however:https://www.wendangku.net/doc/ee7852148.html,ter,however,hecha ngedhismind. 他的第一反应是不行，但后来他改变了主意。 b.still:It'sraining;stillI'dliketogo.天在下雨，但我还是要去。 ③词组 allthesame:Sheisnaughty,allthesamewehavetolaughatherjokes. 她很调皮，但对她的恶作剧我们还是要发笑。 3、表示因果的连词： ①for可以表示"因为"，但引导的不是从句，而是并列分句，对前面情况加以解释，常用逗号把它和前面的分句分开，这在书面语中比较多见。 Thedayswereshort,foritwasnowDecember.白天很短，因为现在已经是十二月。 Shemusthavegoneoutearly,forshehadnotcomeforbreakfast. 她肯定一早出去了，因为她没来吃早饭。 ②so表示结果，可译为"因此"、"所以"。 Ourcaseswereheavy,sowetookataxi.我们的箱子很重，因此我们坐了出租车 ③therefore为副词，也表示同样的意思---"因此"，可放句前： Hehadgone;shethereforegavethemoneytome.他走了，于是她把钱给了我。 4、both...and的用法

第1章思考题及参考答案

第一章思考题及参考答案１. 无多余约束几何不变体系简单组成规则间有何关系？答：最基本的三角形规则，其间关系可用下图说明：图a 为三刚片三铰不共线情况。图b 为III 刚片改成链杆，两刚片一铰一杆不共线情况。图c 为I 、II 刚片间的铰改成两链杆（虚铰），两刚片三杆不全部平行、不交于一点的情况。图d 为三个实铰均改成两链杆（虚铰），变成三刚片每两刚片间用一虚铰相连、三虚铰不共线的情况。图e 为将I 、III 看成二元体，减二元体所成的情况。 2．实铰与虚铰有何差别？答：从瞬间转动效应来说，实铰和虚铰是一样的。但是实铰的转动中心是不变的，而虚铰转动中心为瞬间的链杆交点，产生转动后瞬时转动中心是要变化的，也即“铰”的位置实铰不变，虚铰要发生变化。 3．试举例说明瞬变体系不能作为结构的原因。接近瞬变的体系是否可作为结构？答：如图所示AC 、CB 与大地三刚片由A 、B 、C 三铰彼此相连，因为三铰共线，体系瞬变。设该体系受图示荷载P F 作用，体系C 点发生微小位移 δ，AC 、CB 分别转过微小角度α和β。微小位移后三铰不再共线变成几何不变体系，在变形后的位置体系能平衡外荷P F ，取隔离体如图所示，则列投影平衡方程可得 210 cos cos 0x F T T βα=?=∑，21P 0 sin sin y F T T F βα=+=∑ 由于位移δ非常小，因此cos cos 1βα≈≈，sin , sin ββαα≈≈，将此代入上式可得 21T T T ≈=，()P P F T F T βαβα +==?∞+，由此可见，瞬变体系受荷作用后将产生巨大的内力，没有材料可以经受巨大内力而不破坏，因而瞬变体系不能作为结构。由上分析可见，虽三铰不共线，但当体系接近瞬变时，一样将产生巨大内力，因此也不能作为结构使用。 4．平面体系几何组成特征与其静力特征间关系如何? 答：无多余约束几何不变体系?静定结构（仅用平衡条件就能分析受力）有多余约束几何不变体系?超静定结构（仅用平衡条件不能全部解决受力分析）瞬变体系?受小的外力作用，瞬时可导致某些杆无穷大的内力常变体系?除特定外力作用外，不能平衡 5．系计算自由度有何作用？答：当W >０时，可确定体系一定可变；当W <０且不可变时，可确定第４章超静定次数；W ＝０又不能用简单规则分析时，可用第２章零载法分析体系可变性。 6．作平面体系组成分析的基本思路、步骤如何？答：分析的基本思路是先设法化简，找刚片看能用什么规则分析。
