江苏开放大学形成性考核作业学号姓名课程代码课程名称评阅教师第2次任务共4次任务江苏开放大学任务内容：（请将各题答案填在作答结果相应位置）专题讨论：规模经济：中国彩电行业的洗牌案例内容改革开放之后，国人的收入明显增加，冰箱、彩电、洗衣机替代自行车，缝纫机和收音机成为人们家庭建设上追求的新“三大件”。

当时的电视机是主要黑白的，后来彩电才进入了为数不多的家庭。

可无论是黑白电视还是彩色电视，由于日本的品牌质量出色，在市场上几乎占据了绝对的优势，人们茶余饭后津津乐道的是日立、东芝、索尼、JVC、三洋、松下等品牌。

当时中国的经济还处于极度的短缺当中，电视机在“票证时代”还是一种奢侈品，人们需要凭关系、走后门才能买到，如果哪个家庭拥有一台日本原装进口的14寸电视机是件令人羡慕的事。

1978年国家开始批准引进彩电生产线后，中国电视机行业开始迅猛发展。

据统计，到1985年，全国共引进了113条彩电装配生产线，几乎遍布于全国各省；彩电企业也遍地开花，到九十年代中期，全国的彩电企业超过了200家。

在这股迅猛发展的浪潮中，涌现出了长虹、TCL、康佳、创维、海尔等为国人所熟知的品牌。

1996年3月26日，长虹挑起行业内的第一次大规模价格战，电视机行业从此全面洗牌，据国家信息中心的统计，20世纪90年代中后期，有竞争力的彩电品牌尚有5、60个，价格战的冲击使得很多企业退出市场，高路华、乐华、嘉华、熊猫等品牌陆续消失；2006年，TCL、长虹、康佳、创维、海信、海尔和厦华等七大品牌占据了国内市场约75%的市场份额。

彩电业寡头垄断的市场结构特征越来越明显。

案例分析任何产业都有其适度的发展规模，而彩电业是一个规模经济性较为显著的产业。

二十世纪八十年代的迅猛发展使得中国电视机的产量大增，到1985年我国电视机年产量就超过美国，达到1663万台，成为仅次于日本的世界第二大电视机生产国。

1987年，我国电视机产量达到1934万台，一举超过日本，成为世界上最大的电视机生产国。

Our reactions help to determine whether our child will repeat his behavior or whether he will do something different. This statement is a very important part of a principle of behavioral psychology.The principle states that a behavior is influenced or affected by how the environment ---- people, places and things ---- immediately responds to the behavior. Perhaps without realizing it, you have used this principle many times.On the occasion when you told your child what a good boy he was after he cleaned up his room, you used the principle. When you sent your child to his room for fighting with his brother, you used the principle. When I gave Kim a cookie after she started to cry, I used the principle. In each of these examples, a particular behavior occurred first ---- cleaning up a room, fighting, and crying.In addition, there was a reaction to eachbehavior ---- the child was praised, sent to his room, or given a cookie. By these actions, we have influenced the previous behaviors and have helped to determine whether those behaviors will occur again in the future.(10分)1、1.What is the lecture mainly about?（单选题）A、Children and environmental protection.B、Children’s behavior and fighting.C、Children’s behavior and our response.D、Children and principles.2、2.On what kind of principle is the lecture based?（单选题）A、A principle in chemistry.B、A principle in behavioral psychology.C、A principle in physics.D、A principle in geology.3、3.Who do you think the audience at this lecture might be?（单选题）A、T eachersB、DoctorsC、Social workers.D、Parents4、4.According to the lecture, why was the child sent to his room?（单选题）A、As a kind of punishment.B、As a kind of reward.C、As an experiment on the principle.D、As an example of the principle.5、5.What does the lecturer mean by "environment"?（单选题）A、Rooms, cookies and toys.B、Water, air and forest.C、People, places and things.D、Family, school and friends.2、The fridge is considered a necessity. It has been so since the 1960s when packaged food first appeared with the label: “store inthe refrigerator”.In my fridgeless Fifties childhood, I was fed well and healthily. The milkman came daily, the grocer, the butcher, the baker, and theice-cream man delivered two or three times a week. The Sunday meat would last until Wednesday and surplus(剩余的) bread and milk became all kinds of cakes. Nothing was wasted, and we were never troubled by rotten food. Thirty years on, food deliveries have ceased; fresh vegetables are almost unobtainable in the country.The invention of the fridge contributed comparatively little to the art of food preservation. A vast way of well-tried techniques already existed ? natural cooling, drying, smoking, salting, sugaring, bottling ...What refrigeration did promote was marketing ? marketing hardware and electricity, marketing soft drinks, marketing dead bodies of animals around the globe in search of a good price.Consequently, most of the world’s fridges are to be found, not inthe tropics where they might prove useful, but in the wealthy countries with mild temperatures where they are climatically almost unnecessary. Every winter, millions of fridges hum away(不断地嗡嗡作响) continuously, and at vast expense, busily maintainanartificially-cooled space inside and artificially-heated house ?while outside, nature provides the desired temperature free of charge.The fridge’s e ffect upon the environment has been evident, while its contribution to human happiness has been insignificant. If you don’t believe me, try it yourself, invest in a food cabinet （橱柜）and turn off your fridge next winter. You may miss the hamburgers,but at least you’ll get rid of that terrible hum.(10分)1、1.The statement “In my fridgeless Fifties childhood, I was fedwell and healthily.” (Para.2) suggest that _______.（单选题）A、the author was well-fed and healthy even without a fridge inhis fiftiesB、the author was not accustomed to using fridges even in hisfiftiesC、there was no fridge in the author’s home in the 1950sD、the fridge was in its early stage of development in the 1950s2、2.Why does the author say that nothing was wasted before the invention of fridges?（单选题）A、People would not buy more food than was necessary.B、Food was delivered to people two or three times a week.C、Food was sold fresh and did not get rotten easily.D、People had effective ways to preserve their food.3、3.Who benefited the least from fridges according to theauthor?（单选题）A、InventorsB、ConsumersC、ManufacturersD、Traveling salesmen（巡回推销员）4、4.Which of the following phrases in Para.5 indicates the fridge’s negative effect on the environment?（单选题）A、“Hum away continuously”.B、“Climatically almost unnecessary”.C、“Artificially-cooled space”.D、“With mild temperatures”.5、5.What is the author’s overall attitude toward fridges?（单选题）A、NeutralB、CriticalC、ObjectiveD、Compromising完形填空题1、Scientists have studied consumer behavior recently and found 21 the look of the package has a great effect 22 the"quality" of theproduct and on how well it 23 , because "Consumers generallycannot 24 between a product and its package. Many products are packages and many packages are products," as Louis Cheskin, the first social scientist studying consumers’ feeling for packaging, noticed.Colors are one of the best tools in packaging. Studies of eyemovement have shown that colors draw human 25 quickly. Take V8 for example. For many years, the bright red color of tomatoes and carrots on the thin bottle makes you feel that it is very good for your body. And the word"green" today can keep food prices26 .27 are another attraction. Circles often suggest happiness and peacefulness, because these shapes are 28 to both the eye and the heart. That’s 29 the round yellow M signs of McDonald’s are inviting to both young and old.This new consumer response to the colors and shapes of packages reminds producers and sellers that people 30 to satisfy both body and soul.(10分)1、21（单选题）A、thatB、whatC、suchD、as2、22（单选题）A、withB、ofC、atD、on3、23（单选题）A、buysB、sellsC、offersD、works4、24（单选题）A、showB、displayD、differ5、5（单选题）A、attentionB、eyeC、presenceD、perception6、26（单选题）A、to go upB、to go downC、going upD、going down7、27（单选题）A、PackagesB、ShapesC、T oolsD、Products8、28（单选题）A、pleasantlyB、pleasingC、pleasedD、pleasure9、29（单选题）A、howB、becauseC、whereD、why10、30（单选题）A、sellB、makeD、produce2、Directions：There are 10 blanks in the following passage.

A)Once a week.B)Twice a week.C)Three times a week.D)Four times a week.M: Your son seems to have made much progress in playing the piano. Does he attend any piano classes?W: Yes, he takes lessons twice a week, but from next week on, he will go to the class on Saturday evenings, too.Q: How often will the woman’s son have piano lessons from next week on?答案：C 分析：看选项就知道这题考的一个频度，那么到底是几次呢？我看对话怎么说的，男人的话不是很重要，只是引出问题。

女人的回答是本题的关键，女人先说是twice a week ，但千万不要忙着选 B（事情不会那么简单，听到的一般不是正确答案），女人接着来了也“but”转折，说从下周开始，他儿子星期六也将去上课。

Ok 那么本来是两次，下周起再加上周六的课，答案就是C 三次。

2.第二次作业问题2A) He left his notes at home.B) He doesn’t know where his notes are.C) He doesn’t want to land his notes to the woman.D) He agrees to lend her his notes.W: Do you mind if I borrow your notes.M: No, of course not. They are on my desk.Q: What does the man mean?答案：D 分析：四个选项中有一组对立项 C D 一个是同意借笔记，一个是不愿意借，答案很有可能是其中之一。

第三章1．观察下列方程并判断其变量是否呈线性？系数是否呈线性？或都是？或都不是？1) i i i X Y εββ++=3102) i i i X Y εββ++=log 103) i i i X Y εββ++=log log 104) i i i X Y εβββ++=)(2105) i ii X Y εββ+=10 6) i i i X Y εββ+-+=)1(1107）i i i i X X Y εβββ+++=1022110解：（1）（2）（3）（7）变量非线性，系数线性。

（4）变量线性，系数非线性。

（5）（6）变量和系数均为非线性。

2．多元线性回归模型与一元线性回归模型有哪些区别？解：一元线性是说一个解释变量对被解释变量的影响。

多元线性则是多个解释变量对被解释变量的影响。

多元线性回归模型与一元线性回归模型的区别表现在如下几个方面：一是解释变量的个数不同；二是模型的经典假设不同，多元线性回归模型比一元线性回归模型多了个“解释变量之间不存在线性相关关系”的假定；三是多元线性回归模型的参数估计式的表达更为复杂。

计算一元线性回归方程的最小二乘法是整个回归思想中的核心。

在多元线性回归方程中，由于变量的增多，最普遍的会出现异方差性，还会有时序性等影响着回归方程的拟合度。

3．为什么说最小二乘估计量是最优的线性无偏估计量？多元线性回归最小二乘估计的正规方程组，能解出唯一的参数估计的条件是什么？解：在满足经典假设的条件下，参数的最小二乘估计量具有线性性、无偏性以及最小性方差，所以被称为最优线性无偏估计量（BLUE ）。

对于多元线性回归最小二乘估计的正规方程组，能解出唯一的参数估计量的条件是解释变量间不完全线性相关。

4．多元线性回归模型的基本假设是什么？试说明在证明最小二乘估计量的无偏性和有效性的过程中，哪些基本假设起了作用？解：随机误差项零均值，同方差，无序列相关且服从正态分布。

解释变量非随机，如果是随机的，不能与随机误差项相关，解释变量之间不存在共线性。
