Book one Unit 6 Animal IntelligenceText AThe first time:The first period:I. Preview:1. Let the students be familiar with some important words and phrases in Text A, which will enable them to better understand the text: controversy, encounter, convince, suspicious, blank, relieve, figure out, assess, inaccessible, release, deceive and wipe out.2. Ask the students to search for some information about animal intelligence through Internet or the Encyclopedia while keeping the question in mind that whether animals do have intelligence and what kind of presentation they may show.3. Read Text A in general and paragraph 5&6 in Text B.II. Check the homework left last time when the fifth unit was finished.III. Introductory remarks (Ts’ words):In unit 5, we’ve talked about romance. Of course, it’s about the romance of us human beings. But, do we believe that animals will also fall in love? In this unit, Text B, we have examples showing that animals do have certain affections to the one of the same kind but the opposite sex. As we’ve read paragraphs 5&6 in Text B, the point has been proved in someway.Well, from the stories, we see that animals really have their own way of thinking. But, what animals really think? Do they have intelligence as we do?IV. Check the preview work through discussion:1. What’s the meaning of intelligence? And, what about animal intelligence?→Intelligence refers to the power of perceiving, learning, understanding, and knowing. It also means mental ability.As for animal intelligence, it involves such factors as the ability to learn, to solve new problems, or to create novel solutions to familiar problems and reasoning. The last one means that some animals have the ability to benefit from the experiences of others. That’s what we can find in the third story in Text A, that Towan is clever to do the similar trick as Melati.2. Ask Ss to tell some interesting stories concerning animals’ presentation of intelligence. Here are also two samples.→Story one: My parents once raised a dog named Doudou. One day, my father left his coat behind in the scallion field. Doudou stayed beside the coat until my father returned to the scallion field and looked for his coat. Then, he went home happily together with my father.Story two: Once in Yunnan Province, a boa saved the son of his master from a river.Ts may list some other animal behaviors to arouse the Ss’ interests:E.g.: Bees communicate a food source to other members of the hive by means of various “dancing”.Some other species can communicate by sight, taste or odor, electrical impulse (fish), or touch, and many animals have more than one system.Conclusion: From all above, we find that animals do display intelligence in some areas. Let’s read the text and find more examples of animal intelligence.V. Global reading tasks.The second period: Detailed reading Tasks:Part 1 (paragraphs 1-2)I. Let the students reread the first two paragraphs, and think about the questions:1.What is the traditional way to examine the intelligence of animals?→experiments designed to teach human signs.PS:For example, in one early study, the intelligence level of animals was measured in terms of the human capacities required to perform parallel acts. Such a method led to gross overestimation of intelligence of the animal being studied. (Ts may take this as part of the Background Information.)2.What is the author’s idea?→to observe the animal’s performance for their own purposesII. Difficult Sentences:1. Wondering whether there might be better ways to explore animal intelligence than experiments... not when scientists ask them to. (Paragraph 1)------ I want to know if there might be better ways to find out more about animal intelligence than those experiments which are designed to teach human language to animals. Then I realized one thing that seems to be very clear now. If animals can think, they will probably do their best thinking for themselves. Animals will not think very hard when scientists ask them to do so.2. Most do not study animal’s intelligence, but they encounter it, and the lack of it, every day. (Paragraph 2)----- Most of the zookeepers do not research on animal intelligence, but they meet animal intelligence unexpectedly every day. They also meet the situation that animals show little intelligence everyday.3. The stories they tell us reveal what I’m convinced is a new window on animal intelligence: the kind of mental feats animal perform when dealing with capacity and the dominant species on the planet—humans. (Paragraph 2)----- The stories they tell us show something that I believe is a new aspect of animal intelligence. They tell us about the marvelous thinking that animals do when they deal with the situation of being caught and human, the most powerful species on the earth.III. Important Words and expressions:controversy over/about something encounter problems/difficulties/oppositions/resistanceconvince somebody of/to do something do one’s best thinkingserve one’s own proposePart 2 (paragraphs 3-6)I. Reread this part and do the exercises:1. True or false questions:a. Colo’s example indicates that some animals know quite well how to negotiate with the keepers. _T__b. Colo is a good bargainer, and this case shows that animals may really have intelligence. T_c. Mile’s experiment to teach Chantek to share things proves to be a great success. F_→Mile’s experiment to teach Chantek to share things proves to be a great failure.2. Ask the students to fill in the blanks with the information mentioned in this part, esp. the animals’ action. Then figure out the author’s purpose.a. Colo: Broke the key chainAuthor’s purpose:Animals know how to negotiate with people.b. Chantek: 1) Expanded the money supply by breaking plastic chips in two;2) Found pieces of tin foil and tried to make copies of metal chipsAuthor’s purpose: Animals can even handle the moneyIII. Difficult Sentence:Arriving on the scene, Jendry offered Colo some peanuts, only to be met with a blank stare. (Paragraph 3) ----- When she got to the place where Colo was, Jendry gave Colo some peanuts, but here good will was not well accepted and she got a blank stare from Colo.IV. Important Words and Expressions:a blank stare maintain eye contact raised the stakes careful bargainerspend on treats trade one thing for another catch up with somebody/somethingonly to do why (not ) do be suspicious of/aboutHomework: 1. Do the exercises of structure on pages 181&182. (only to do, why do/not do)2. Preview the left part of the text.The second time:Part 3 (paragraphs 7-10)I. Check the homework and go on to the new stories.II. Five minutes are given to the students to finish reading this part; two questions will be put forward.1. What did Orky do in this section?→Allowed somebody to stand on his head to reach up and release the baby2. What can you get from this example?→Animals can assess the situation and make a right decision.III. Difficult sentence:This is true, but I do not think it goes far enough. (Paragraph 7) ----- What behaviorist say is right, but I do not think their explanation helps very much.IV. Important Words and Expressions:in one’s interest make judgments emergency care go wrong assess based onthrive at throw up size up keep steady slide intoPart 4 (Paragraphs 11-12)I. Ask the students to read through this part quickly , then to answer the following questions.1.How did Melati and Towan play the trick on Shewman ?→Melati: Hid an orange in her other hand. Towan:Hid an orange underneath his foot.2.What did the author want to tell us？→Animal intelligence can be seen in their attempts to deceiveII. Let the students do some true or false questions according to Part 3 and Part 4.1.Behaviorists say that animals cooperate with human beings for their own benefit. ( T )ule believed that Orky, a killer whale, was the most intelligent animal she had ever seen. ( F )→Laule believed that Orky, a killer whale, was the most intelligent animal she had ever worked with.3.Some animals’intelligence can be seen in their attempts to deceive. ( T )4.Orky allowed somebody to stand on his head to reach up and release the baby because he had been trained to do so.( F )→Orky let somebody stand on his head to reach up and release the baby, but he had not been trained to do so.5.Animals can learn from each other in playing some tricks. Towan is a good example. ( T )III. Difficult sentence:Instead of moving away to get it, Melati looked Shewman in the eye and held out her hand. (Paragraph 11)------ Melati looked directly and steadily at Shewman without moving away to get it.Part 5 (Paragraph 13)I. While reading this paragraph, think about the function of the last paragraph. How do you understand it?→It concludes the whole passage--- animal intelligence not only exist but also plays a very important role in their survival. II. Difficult sentences:1. If life is about survival of a species---- and intelligence is meant to serve that survival--- then we can’t compare with pea-brained sea turtles, which were here long before us and survived the disaster that wiped out the dinosaurs.----- If the purpose of life is to survive and intelligence is for survival, then our intelligence can’t be compared with that of the pea-brained turtle. They were on this earth long before we human beings and they even survived the survived the disaster that destroyed thedinosaurs.2. … even if their horizons are more limited than ours.---- even though they can’t assess the world in the same way as we do because of more limited knowledge and experience.III. Important Words and Expressions in the two parts above:deceive somebody into doing something look somebody in the eye hold outinaccessible (get/have access to somebody/something ) move off hold one’s gaze steadilygive in be meant to do something wipe outPost-reading tasks:Ts may give a general conclusion about the whole text and answer the questions raised by the students.Homework: 1. Review the important words we’ve learned.2. Finish all the exercises in the book.The third time:I. Check the homework and do some exercises:a. Words Dictation:intelligence controversy encounter convince dominant suspicious blank negotiate maintain relieve undertake thrive emergency release evidence deceive survival disaster figure out wipe outb. Paragraph dictation: The following paragraph will be read three times; Ss should listen to the paragraph carefully for the first two times. For the third time, Ss should write down sentence by sentence of what they heard. Then check it.Why don’t birds get lost on their long flights from one place to another? Scientists have been puzzled over this question for many years. Now they fill in the blank.Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly by night? Tests with artificial stars have proved that certain night flying birds are able to follow the stars in their long-distance flights. What do they do when the stars are hidden by clouds? Apparently, they find their ways by such landmarks as mountain ranges, coast lines and river courses. But when it’s too dark to see these birds circle helplessly, unable to get their ways.II. Deal with the exercises of Text A. (partly & selectively)III. Writing skills:The passages in this unit are expositions. The writing style is not strange to us since we have come to learn about it in Unit Two. The purpose of an exposition is to make something clear to the reader, and its focus is to explain, define and interpret. It is widely used in our daily life. Students’ attention can be directed to some writing techniques of an exposition.1. Using examples to support to a topic. For example, in this article, the author employs the stories of gorilla, three orangutans, and a killer whale to support his point.2. Using transitional devices to make a coherent writing.a. Headings and subheadings provide natural transitions between paragraphs and sections.For example, in this text we have three subheadings for three parts of the main body of the passage. They are: “Let’s Make a Deal”, “Tale of a Whale”, “Primate Shell Game”. The subheading directs readers’attention to another demonstration of animal intelligence.b. Transitional sentences.c. Conjunctions.The sixth periodText B Pre-reading tasksI.Before explaining text B, we will do some listening work together. Listen to the following passage carefully, then, answer the following questions.When lionesses give birth to their young, they usually have three or four cubs to a litter, and stay with them for about two years to protect them from danger when they are tiny, and to teach them the fine art of hunting. They have a very closely-knit family life. But when a lioness has her young she is usually in a very nasty protective disposition. But she is very patient and accommodating towards her cubs. A unique thing about lionesses is that they will nurse cubs from another litter besides their own. They never care less whose cubs they are.II. Ask two Ss to give a report about myquestion left last class. Do animals love each likehuman beings?(hint: some animals do love each other deeplyand faithfully. What’s more, their wooingmethods are even more fantastic. Their devotedaffection is touching to some degree. ) Onepicture about some animals’wooing methodswill be presented to help the Ss have a deepunderstanding of animals’ love.Global-reading tasks (15 minutes )I. Ss are given 10 minutes to finish scanning thetext, to count how many examples arementioned in the text. ( 5: Ado, a male parrot,Timmy, Coyotes, Tibby )II.Then ask the Ss to tell the organization of thetext.Part one: ( 1-2 ) Some animals do displayvarious feelings under different circumstances.Part two: ( 3-14 ) Concrete examples areoffered to prove that animals may fall in love.Part three: ( 15 ) Though rejectionremains, the fact that animals experienced, areexperiencing, will experience joy, anger, sorrow,and happiness everywhere. ( the seven humanemotions: joy, anger, sorrow, fear, love, hate, desire) ( 15 minutes )Starling:椋鸟blue tit:蓝山雀quack: 呱呱叫Detailed-reading tasksPart one: Group discussion1. After scan the fist part in two minutes, Ss have a discussion on the following topics:Topic one: what’s true love? Reference: Two persons must love, trust one another. They should help, care, and cherish each other in any case. If one is ill, disabled, or is dying, another is willing to accompany and take good care of her or him wholeheartedly, not to desert him or her. If necessary, one may dedicate his or her life to his or her lover.Topic two: How do you think animals nurse their babies affectionately?Reference: to a large extent, it should be thought as natural instincts.Homework: Ask Ss to read paragraph3, 5, 6, 7, 10, 12, and 13 carefully, and describe those animals’ behavior mentioned in three—four adjective phrases respectively.Ado in para3: silent, depressed, and alone Athan: indifferent, glad, happyTimmy: reluctant, excited, sad, hurt Coyote: affectionate, gentle, happyTibby: get lost, strange, nostalgicThe fourth timeI First check the answers of the homework left last class. Then go on with what we stopped last time.II. Structure:a. what about-----used to make a suggestion e.g.: What about dinner at my place next week?b. how about----used to make a suggestion about what to do e.g.: No, I’m busy on Monday. How about Tuesday at seven?How about doing somethingIII. Useful expressionsBe cautious about doing sth 干----时很谨慎prefer to do/doing 更喜欢prefer A to B 比起B,更喜欢AAdequate parental care 足够的亲本照顾 a sense of loss 失落感IV. ensure ( US insure ) assure guaranteeAssure: tell sb positively or confidently 向-----保证，cause sb to be sure or feel certain about ~ sb of sth 使确信E.g.: I ~ you they will be perfectly safe with us. Assurance n..保险Ensure: make sure guarantee 确保，保证 e.g.: Please ~ that all the lights are switched off at night.Guarantee: promise (usually in writing) in a transaction will be fulfilled e.g.: the watch comes with a year’s ~.Part twoI. Ask the Ss to underline Ado’s, Athan’s，Timmy’s, coyotes’, and Tibby’s behavior respectively in the text. Then tell us theimplied meaning.Ado behavior: He stood…body, he hung his head…became vacant. didn’t have heart…sharply. Pulled himself together …another mate.Implied meaning: fell sorrowful and a sense of loss.Parrot: behavior: ignored a fine-feathered young female but thought an older female in extremely poor condition was the love of his life. The two birds…eventually produced young.Implied meaning: Instinct may…they will love.Timmy: behavior: declined to…at once.Implied meaning: Many species…of their species.Coyotes: behavior: Observations indicate that…sexually active. Pairs can be observed…curled up to sleep.Implied meaning: There is evidence… each other.Tibby：behavior Tibby made a habit…village. She tried to…his house. Acted strangely, even trying to follow him indoors.Implied meaning: An animal raised… when it grows up.II. Important language points :Lay ~ sth aside: put sth aside lay-off: dismissal of a worker, esp for a short time. Layout: arrangementVacant:not filled or occupied a ~ post blank: a ~ stare, look, a ~ mind 茫然的心情Compare A to B 把A 比成B compare A with B 把A和B向比较Shed/cast light on sth: make sth clear or easy to understandIII. Let the students translate the following phrases into Chinese:Put human emotions in animals 赋予动物人类的情感Cross the bridge of reality 逾越现实的鸿沟Whatever distinctions may be made between the love of two people and the love of two animals, the essence frequently seems the same. 无论人类的男欢女爱与动物雌雄相悦之间有多少取别，两者的本质常常是一致的。

Financial institutionsalso face credit risk to counterparties with whom the trade and clientsto whom they lend.15-W hy do managers of financial institutions care so much about the activities of the Federal Reserve System?Because the actions of the Federal Reserve affects interest rates,inflation, and business cycles, all of which have an important impacton the profitability of financial institutions.16-The following table lists foreign exchange rates between U.S. dollars andBritish pounds during April:Date U.S.Dollarsper GBP Date U.S.Dollarsper GBP4/1 1.9564 4/18 1.7504 4/4 1.9293 4/19 1.7255 4/5 1.914 4/20 1.6914 4/6 1.9374 4/21 1.672 4/7 1.961 4/22 1.66844/8 1.8925 4/25 1.66744/11 1.8822 4/26 1.68574/12 1.8558 4/27 1.69254/13 1.796 4/28 1.72014/14 1.7902 4/29 1.75124/15 1.7785Which day would have been the best day to convert $200 into British pounds? The best day is 4/25. At a rate of $1.6674/pound, you would have£119.95.Which day would have been the worst day? What would be the difference in pounds? The worst day is 4/7. At $1.961/pound, you wouldhave £101.99, or a difference of £17.96.Chapter 21.Why is a share of Microsoft common stock an asset for its owner and aliability for Microsoft?The share of Microsoft stock is an asset for its owner because itentitles the owner to a share of the earnings and assets of Microsoft.The share is a liability for Microsoft because it is a claim on itsearnings and assets by the owner of the share.2.If I can buy a car today for $5,000 and it is worth $10,000 in extra incomenext year to me because it enables me to get a job as a traveling anvil sellershould I take out a loan from Larry the loan shark at 90% interest rate if noone else will give me a loan? Will I be better or worse off as a result of taking out this loan? Can you make a case for legalizing loan-sharking?Yes, I should take out the loan, because I will be better off as a result ofdoing so. My interest payment will be $4,500 (90% of $5,000), but as aresult, I will earn an additional $10,000, so I will be ahead of the gameby $500. Since Larry’s loan-sharking business can make some peoplebetter off, as in this example, loan sharking may have social benefits.(One argument against legalizing loan sharking, however, is that it isfrequently a violent activity.)3.Some economists suspect that one of the reasons that economies indeveloping countries grow so slowly is that they do not have well-developed financial markets. Does this argument make sense?Yes, because the absence of financial markets means that funds cannotbe channeled to people who have the most productive use for them.Entrepreneurs then cannot acquire funds to set up businesses thatwould help the economy grow.4.“Because corporations do not actually raise any funds in secondary markets,they are less important to the economy th an primary markets.” Comment.This statement is false. Prices in secondary markets determine theprices that firms issuing securities receive in primary markets. Inaddition, secondary markets make securities more liquid and thuseasier to sell in the primary markets. Therefore, secondary marketsare, if anything, more important than primary markets.5.If you suspect that a company will go bankrupt next year, which would yourather hold, bonds issued by the company or equities issued by the company?Why?You would rather hold bonds, because bondholders are paid offbefore equity holders, who are the residual claimants.6.How can the adverse selection problem explain why you are more likely tomake a loan to a family member than to a stranger?Because you know your family member better than a stranger, youknow more about the borrower’s honesty, propensity for risk taking,and other traits. There is less asymmetric information than witha stranger and less likelihood of an adverse selection problem, withthe result that you are more likely to lend to the family member.7.Think of one example in which you have had to deal with the adverseselection problem.8.Why do loan sharks worry less about moral hazard in connection with theirborrowers than some other lenders do?Loan sharks can threaten their borrowers with bodily harm ifborrowers take actions that might jeopardize paying off the loan.Hence borrowers from a loan shark are less likely to engage inmoral hazard.9.If you are an employer, what kinds of moral hazard problems might youworry about with your employees?You would be concerned that they would carry out theirresponsibilities – removing a poorly performing employee is anexpensive endeavor. They might steal or commit fraud.10.If there were no asymmetry in the information that a borrower and a lenderhad, could there still be a moral hazard problem?Yes, because even if you know that a borrower is taking actions thatmight jeopardize paying off the loan, you must still stop the borrowerfrom doing so. Because that may be costly, you may not spend thetime and effort to reduce moral hazard, and so moral hazard remainsa problem.11.“In a world without information and transaction costs, financialintermediaries would not exist.” Is this statement true, false or un certain?Explain your answer.By looking at the three reasons for financial intermediaries to existone can see that this deals with the transaction costs and adverseselection issues. Risk sharing may still be an issue. A small investormay not be able to build a well-diversified portfolio and thus afinancial intermediary may be necessary to construct this for him.12.Why might you be willing to make a loan to your neighbor by putting funds ina savings account earning a 5% interest rate at the bank and having the banklend her the funds at a 10% interest rate rather than lend her the fundsyourself?Because the costs of making the loan to your neighbor are high (legalfees, fees for a credit check, and so on), you will probably not be ableto earn 5% on the loan after your expenses even though it has a 10%interest rate. You are better off depositing your savings with afinancial intermediary and earning 5% interest. In addition, you arelikely to bear less risk by depositing your savings at the bank ratherthan lending them to your neighbor.13.How does risk sharing benefit both financial intermediaries and privateinvestors?Risk sharing benefits financial intermediaries because they are able toearn a spread between the returns they earn on risky assets and theyreturns they pay on the less-risky assets they sell. Investors benefitbecause they are able to invest in a better diversified portfolio thenwould otherwise be available.14.Discuss some of the manifestations of the globalization of world capitalmarkets.Increasing globalization of financial intermediaries such as banks andother institutions. Interconnectedness of financial markets such asstock markets etc (one can observe a high degree of correlationbetween these). Also disruption in a major foreign market can causedisruption in the US and vice versa.Extra Questions:•Think about investments on .–Quite a bit of information can be found either on the website or in the prospectus -/Downloads/Legal/Prosper_Prospectus_2012-07-19.pdf–What potential returns are described on the website?–Returns range from 5.24% for AA rated borrowers to 14.75% for HR rated borrowers. Lending is for periods of 1, 3 or 5 years with only 3years being available to HR.–What are the significant risks to investing?–’s prospectus from pages 22-45 lists many different risks.Here are several - there is interest rate risk. If you lend at 7% andinterest rates go to 10% then on a present value basis you will havelost money. There is credit risk – first you are lending on anunsecured basis, second it is not clear what happens to your loan if goes under. There is asymmetric information risk – theinformation that the borrower gives to take out the loan is not verified.There is liquidity risk. There is a secondary market but it is not clearwhether it is liquid. There is also prepayment risk – the risk that aborrower pays back the loan early. To think about this risk imaginethat you have lent money at 10% and then interest rates fall to 5%halfway through the life of the loan. If the borrower prepays the loanthen you will only be able to reinvest the money at a similar yield bytaking on additional risk.–When investing through the website what does one buy?–An investor is buying a “Borrower Payment Dependent Note.” This information can be found in the prospectus. will issuethe notes–On the website are large numbers of borrowers seeking funds. What alternatives might these borrowers have for raising funds? Whatreasons might drive them to raise funds here over those alternatives?–Several main alternatives to would be other peer-2-peer lending sites, banks, credit unions and other retail based depositoryinstitutions and credit cards. A rational borrower would investigateall of these options as well as for raising funds for theirpurposes. With this assumption it could be that funds are moreexpensive or unavailable through these other sources or that is a cheaper source of funds than these other sources.–Is there a secondary market for an investment on ? How does it work?–Yes, advertises a service they call FOLIO in which one can list notes that you own and want to sell.•On the website look up information about the fund VFISX. Within the summary prospectus find:–Over the past 10 years what are the max and min annual return for this fund?–Max is 7.89% in 2007 and min is 1.03% in 2004.–What are the significant risks for investing in this fund?–Income risk – the risk that changes in market rates will reduce the income available to the fund. Interest rate risk – this risk that changesin interest rates will cause bonds held in the fund to change in value.Manager risk – the risk that poor security selection on the part of themanager will cause poor investment returns relative to otherpotential investments.。
