马经课后习题及名词解释(修改版)马经课后习题及名词解释by马奕涵备注:红色题目为复习PPT课后习题第一章名词解释:商品:商品是用来交换的劳动产品,具有使用价值和价值二因素。
使用价值是商品能够满足人们某种需要的有用性;价值是凝结在商品中的一般人类劳动。
商品经济:交换为目的的经济形态,是一个历史范畴。
使用价值:商品能够满足人们需要的属性就是它的使用价值,是指物品的有用性。
使用价值是由物品的自然属性决定的,构成社会财富的物质内容,属于自然范畴。
交换价值:是一种使用价值同另一种使用价值相交换的量的关系或比例。
价值:是凝结在商品中的一般人类劳动。
价值是商品的社会属性。
价值量:商品所包含的价值总量,由生产该商品的社会必要劳动时间决定。
具体劳动:生产商品的劳动的二重之一,在一定的具体形式下进行的劳动叫做具体劳动。
具体劳动创造商品的使用价值。
抽象劳动:生产商品的劳动的二重之一,即撇开了各种具体劳动形态的一般的无差别的人类劳动。
抽象劳动创造商品的价值。
私人劳动:是指以私有制为基础的商品经济中,商品生产者的劳动是按照自己私人的利益和要求所进行的,其劳动具有私人性质。
社会劳动:是指商品生产者的劳动,是提供给社会的,构成社会总劳动的组成部分,其劳动具有社会性质。
社会必要劳动时间:在现有的社会正常的生产条件下,在社会平均的劳动熟练程度和劳动强度下制造某种商品所需要的劳动时间。
劳动生产率:指劳动者生产某种商品的效率或能力。
通常由单位时间内生产的产品数量或单位产品所耗费的时间来表示。
货币:货币是固定充当一般等价物的特殊商品,体现了商品生产者之间的生产关系。
价格标准:价格标准是货币重量单位,是用来衡量货币金属本身的量的,通常由国家法律规定。
纸币:是由国家发行并强制流通的价值符号,它代表贵金属货币执行流通手段职能。
货币流通规律:就是一定时期内商品流通过程中所需货币量的规律。
流通中所需要的货币量=商品价格总额/货币流通速度。
价值规律:是商品按照由社会必要劳动时间决定的价值进行交换的规律。

马政经试题整理以及答案.doc

马政经试题整理辨析1.流动资本指"生产过程中价值发生增殖的资本”。
答:错。
生产资本按照其价值周转方式的不同分固定资本和流动资本(o固定资本是指以厂房、机器设备等形式存在的那一部分生产资本。
)流动资本是指以劳动力形式和以原料、燃料、辅助材料等形式存在的那一部分生产资本。
不变资本和可变资本的划分才是按照资本在价值增殖中的不同作用划分的。
剩余价值不是由全部预付资本带来的,而仅仅是可变资本的产物,工人剩余劳动是剩余价值的唯一源泉2.提高劳动生产率可以增加单位时间内生产的产品数量和价值量答:提高劳动生产率可以增加单位时间内生产的产品数量,但不能增加价值量。
劳动生产率是指劳动生产的能力或效率。
【以单位时间内生产产品的数量计算;同一劳动在单位时间内形成的价值量不变】(商品的价值量由生产商品的社会必要劳动时间决定。
单位商品的价值量和包含在商品中的社会必要劳动量成正比,而与生产者以商品的劳动生产率成反比。
随着生产的发展,劳动生产率变化的总趋势是不断提高的,故单位商品的价值量呈下降的趋势)3.金融资本是指“银行支配而由工业资本家运用的资本”。
答:错。
金融资本是工业垄断资本与银行垄断资本融合在一起而形成了一种新型垄断资本。
银行与工业企业之间的密切关系:①银行与工业企业信贷关系固定化;②银行与工业企业相互持股;③银行与工业企业相互派人员进入公司法人治理机构。
简答1.劳动二重性和商品二因素的关系答:商品的二因素(商品的使用价值和价值)是由生产商品的劳动的二重性(具体劳动和抽象劳动)决定的。
具体劳动创造商品的使用价值,抽象劳动形成商品的价值。
2.资本技术构成和资本价值构成的关系答:一般来说,资本的技术构成决定资本的价值构成,资本价值构成的变化又反映资本技术构成的变化。
但资本价值构成的变化除了取决于资本的技术构成的变化以外,还受到生产资料和劳动和本身价值变化的影响。
(山技术水平决定的生产资料和劳动力之间的比例称为资本的技术构成。

Topic: As far as I am concerned,/personally…since/when/beforeR1: The main reason is that…there is no..R2: In addition/moreover/also/furthermoreConclusion: Overall/therefore/there is no doubt in my mind that /above all/ that is why I think.一、SpeakingTask 11、Is it beneficial for the student to have computers?Provide information/ fast when searching for/software help study Yes. Personally, I think it is not only beneficial for the student to have computers but also necessary for student to have them. The main reason is that computer as an intelligent tool has been a part of our lives which bring convenience to us. They provide information to students to prevent them being nerds. And you don’t have to go to library for searching for some common senses. Just go online and you will know more. Moreover, there are many softwares online that can be downloaded to help students’study. Above those are reasons why I think it is ok for student to have computers.2、describe an important letter or poem or story you havewritten.A letter: leave for USA : friendship/rich:special giftI used to spend a whole day writing a 20 pages letter for my best friend as his birthday gift. It is about many memories of us when we are kids.Since he would leave for USA to continue his study I wrote this letter to make him keep me in my mind. And I gave him lots of supporting and encouragement in this letter. I wish he would never give up because I would believe in him forever.His family is very rich. So when he left many gifts came to him and he was very happy when receiving my gift and he says it was so precious and special. He would keep it forever.I love this guy and gave him my best wishes.Task 21、key words: honest opiniondo you agree or disagree with the following sentence: people should always remain honest?Education of myself/earn trust of others/respectPersonally, I think it is not only necessary for people to remain honest but also necessary for society to remain honest.Most family have given the education on being honest to children when they were very young because they think it is an important virtue and based principle to be a person living in society.Unless being honest you cannot simply earn trust from others then you will feel difficult to communicate with people.Moreover, more honest one people is, more respect he can receive since in today’s modern society people will often need courage to admit their faults. So honest is not just a virtue but a sign of respect.2、do you agree or disagree with the following statement: thegovernment should not rebuild the city.Bring good effects: Transportation improvement/housing condition Personally speaking, rebuilding the city will bring many good effects to citizens.The main reason I think is that transportation system will gain the opportunity to improve. So many transportation measures cannot meet the need of modern pace of people’s working. If government put the money into rebuilding the city’s transportation system and increase the number of tools such as subway and buses it will be very convenient for people to work.Besides, the housing condition has been a problem for government since the number of people increase so fast. So government shoulduse money to reconstruct some buildings to provide people to live.Task 3Reading:一个老师的作业要求每个人负责一个章节,最后综合起来一个review.Listening: girl 说不好,首先大家不会看书了,只管自己的章节和别人的总结,其次期末大家很忙,找别人聊章节不一定有时间。
In the reading passage, the author proposed a suggestion that every student was required to study and hand in a detailed outline of an individual chapter in his class. However, in the conversion, the man opposed this suggestion for the following reasons.First, as the author said, the reason for this suggestion was that there were too many students in the class but according to the man, this would generate a bad consequence that no one would want to finish the whole book. As a result, they would miss out on the knowledge that did not appear in the outlines.Also, the man gave another disadvantage of this suggestion that considering that all of the students would be really busy during the end of the semester, they would not be able to discuss the outlines with other students.Task 41、reading:重建生物的生活环境,环境中的各个因素缺一不可。
listening:老师举了个例子,科学家想种p植物,考虑周全唯独没有加入F,这使得很多reed 之类的植物压制了p,最后加入了F后,问题便迎刃而解。
The reading passage introduces concept called constructedenvironment, which means human build the environmentsuited for the living creatures.In the lecture, the professor mainly talked about detailedexplanation of the definition. He said that all organism have toregulate themselves to adapt to the surroundings. Aconstructed environment is a man-made habit for the wildlifeand it must contain all the necessary factors the organismneeds. To reinforce the theory, the professor gave an examplein his speech. He said that scientists wanted to cultivate avaluable plant in the constructed environment, but it lacked avery important mineral the plant needed to survive. Andwhen scientists added mineral in the environment, the plantbegan to thrive. And that is the example the speakerpresented to demonstrates his concept of constructedenvironment.二、Task 1Describe a difficulty you once meet. Explain how you overcame this difficulty. Give specific details and examples to support your answer.Studying in the uc Berkeley: Language problem, Major problem, life problemIn the last year I applied an opportunity to enter into university of California at Berkeley and attend the summer session program. It was my first time to go to foreign country to study so I was so excited and could not sleep when I got there. But it lasted for a little time then I met some problems. The first problem is language problem. Even though I passed the T oefl exam, I still felt that I hardly could reach the speed of local people’s talking. To solve it I frequently talked with my classmates and learned a lot from them. In the last I adapted the life there.The second problem is major problem. Since I studied the electrical engineering in my country but I chose the web architecture as my major in the program. So there are many students who had learned based knowledge before class’s beginning. All I had to do is to communicate with teacherabout this course. Any way through my effort I got very good scores at the end of course.Task2Do you agree or disagree with the following statement? It is not good for first year students to live in the same dormitory with senior students.Make friends with classmates./same or similar experience and chatting topics.Personally speaking, I totally agree that it is not good for freshmen to live in the same dormitory with senior students. Firstly, most or all students who are same with your grade in your dormitory are your classmates in your major. So you will have same schedule. It is easier to make friends and improve the comprehension with each other. Sometimes if you met problem you maybe rely to these friends to help you.What is more, most of your roommates in the same grade have many topics to chat and interests to play with. You will find more fun in the process of talking and playing. And you will feel you are not alone.So I agree with that it is not good for freshmen to live in the same dormitory with senior students because if seniorstudents cannot bring you above convenience.三、Task 1What are the advantages and disadvantages of allowing students to watch tv at school?First-hand information and some channel can teach great knowledge.Some channels have unhealthy materials such as violent and sexual information.Every coin has two sides and it can be used into the TV. Firstly, TV as a media can provide information to students. Especially in the surrounding of university, students can fast know more about the development of world from TV. It can avoid students being fallen back from the information of world. Besides, there are some channels filled with scientific contents such as discovery, BBC bring affluent first-hand technology to students.However, there are also many disadvantages of TV. Some channels often broadcast much unhealthy information like sexual movies for the profits. And these contents are not suitable for students in the university. It is not good forgrowth of teenagers.Task 2Some people think that teachers should assign homework to students during the class, but others say that teachers should assign homework to students after class using email. Which do you think is better and why?Using internet to manage assignment more convenientWell-organized and avoid students not listening clearly. Personally speaking, I think teacher should assign homework by using email and the reasons are apparently.Firstly, for the teachers, using email to send the assignment is more advanced. There are enormous assignments for teachers to manage. And it will often confuse teachers when they are busy, so using email to manage them is more convenient.In addition, for students, if teacher can use email to send homework the content in email will be well-organized and this will avoid some students in the last lines not listening homework clearly. Then students will hand in the assignment in time in a high level.四、Task 1Describe the problems your country is facing now.Population problem/pollution problem/housing problemThere are too much problems in my country. I want to describe some of them.The first and largest problem is the population problem. There are too many people in my country. For it government has to make some measures to lessen the number because it cause a series of problems such as traffic problem, job problem so it is the basement.The pollution problem is also serious. T oo many factories are pulling the industrial waste into the river and it causes many people who live near the river sick and ill. It is very harmful for human health and the water cannot reach to the standard even though it has been purified for so many times.The housing problem is also very serious. Too many houses have been used to make profits by lots of businessman so there are too many empty houses but the poor men cannot afford the high price and some of them have to be homeless.Do you prefer finishing your work once you got them as quick as possible or to wait until the due time. Why?More time to prepare/less pressure.I prefer to start to work earlier for these reasons.First of all, I can have more time to prepare. For example, for this toefl exam I have prepared for two months because my spoken-english is so bad. I also had an experience in my preparation of my final project in the university. I spent a whole month to search for information from kinds of sources like internet and libraries. In the last I got A level in my transcript. So preparation is a very important part of a process. You have to deal with it seriously. What’s more, if I prepare working earlier I will have less pressure. It is very painful when the deadline is coming but you have not finished your work. So when you have time to do it you should catch it. Then you also have time to revise it.五、Task1Advantage and disadvantage of eating in class.Good for students’ health/bad for studyingPersonally speaking, I think eating in class has both good and badFirstly, there are a lot of students who get up too late because of doing homework lately at night so they have not enough time to eat breakfast. Usually they will choose to bring these breakfasts to school and have them after class. The members of school cannot ban these behaviors because eating breakfast is very significant to teenagers for their growth.However, there are still some disadvantages during the eating process. If they eat on the class and they often cannot the pace of courses and it often affect other people’s listening. The smell even makes many students not focus on teachers but into the food. So it is not good for the class.Besides, it is a impolite behavior to eat food before the teachers who are giving the classes.Task2Some people like collecting old things such as newspaper.

Besides, some of these coins are worthwhile to invest because their prices will increase.六、Task1describe one way to improve the system of education in your country.teachers: high quality/wise educational way/widen perspective Personally speaking, a good way to improve the system of education is to improve the quality of teachers.First of all, many teachers now have lost the faith and principle of teaching. They just want to earn money to live so they opened many classed to teach how to pass exams. By this way they make more money but they focus less and less into their teaching. Secondly, an excellent teacher should have wise educational methods. But now too many teachers only study how to make students’scores higher and succeed entering into the college. A good teacher should teach students reasonable studying way.Last but not least, an standard teacher should have widen perspective and give students more thinking in the depth ofknowledge.Task 2Reading books or listening to audio books?Listening: confused in the pronunciationReading: clear/fast/more feeling/older and typicalPersonally speaking, I prefer reading books to listening audio books. First of all, there are many methods to gain knowledge but reading book is the most typical way. When you listen to audio books there are many confused pronunciation into different words and you need to distinguish them and it is not convenient. But reading book is clear enough.Besides, reading books is very fast. Through a quick glance you can understand the meaning of few lines and your ability of comprehension also can be improved.Furthermore, you can experience great feeling when reading books and you will drop into the contents. It is so wonderful and attractive. So I commend reading books and prefer reading books.七、Task 1One of your friends has been offered a job in a town far away fromhome. Do you think your friend should take this job?Why or why not?Cannot spend time with family and friends/difficult to adapt the culture in the new cityPersonally speaking, I will not recommend my friends going working far away home for a few obvious reasons.Working in a remote city often means you will not be able to spend some time with your family and friends. And especially if you have married you should consider it is so painful to separate with your wife and kids. This is not good for growth of children and keeping of family.And another thing is that it is difficult to adapt to the new life in a different city. You may not used into the lifestyle and food and climate there. The dialect is the most important but you cannot learn it quickly. So you have to suffer above problems if you live in a remote city. You will be hard to survive.Task2When they are studying to prepare for an exam, some students like to study with other people, while others like to study alone. Which do you prefer and why?Ask questions which may be easy to others./share sourcesPersonally speaking, I prefer to study with groups to study alone when preparing for an exam for following reasons.Firstly, when I trap into some problems that I have been confused for a long time but maybe others have understood them. So I only to ask them the solution then I will fast know it and speed my reviewing process.In addition, the sources of a studying group are more than your own sources. So if you study with others you can share these materials with each other and each of you can get high scores in the exam.八、Task1人际交往时good manner重要吗?why?Away from trouble/make new friendsPersonally speaking, I think good manner is very important in interpersonal relationship.At first, good manner can make you away from many troubles. People will prefer using a polite way to communicate with other people. If one person has no good manner, he often got into troubles like disputing or quarrelling. And these problems are not necessary to happen.In addition, good manner can help us make more new friends withothers. Nobody wants to be friend with someone who is annoying. So good manners will earn respect and trust from others and you will have more chances in your life.Task2你喜欢有经验的老师还是没有经验的老师?More efficiently/skill of handling classPersonally speaking, I like experienced teachers better.At first, experienced teachers can deliver their knowledge more efficiently. Usually both experienced and inexperienced teachers have equal and enough knowledge, but the experienced teachers can explain easily to make students convenient to memory. When students have questions, they can make them understand fastly. But inexperienced teachers do not have enough experience or skill to make students understand the knowledge.Secondly, experienced teachers usually can handle class more skillfully. When students make lots of noise, experienced teachers can calm them down fast but inexperienced teachers will feel helpless to solve this problem. Besides, experienced teachers can communicate with students patiently in scientific way.That is why I prefer experienced teachers.。
