PASSAGE 1 (教材课文原文)
With a teeny waist, exaggerated breasts, icy-blue eyes, 21-year-old Valeria says she is the real natural deal. A real-life Barbie, that is.
That’s what she claims anyway, but many people doubt to her claims. Whether she underwent plastic surgery or uses Photoshop remains unclear. On her blog, the model notes that she is the most famous woman on the Russian Internet because of her doll-like appeal. Hundreds of photos on her Facebook page show a wide-eyed, nearly fake-looking Valeria posing in a variety of outfits.
The model did not return requests for comment. If Photoshop is not a factor in getting Valeria’s look, she likely underwent a barrage of plastic surgery. The president of American Society of Plastic Surgeons (ASPS)said, plastic surgery should never be used to transform. oneself into a favorite celebrity or, in this case, a play toy. He also warns patients to keep in mind that plastic surgery is real surgery with real risks, just as with any operation, so the decision should not be taken lightly.
1. Valeria thinks that she is a real-life Barbie.{T; F}
2. Valeria used to accept plastic surgery.{T; F}
3. Valeria writes that she is the most famous woman on the Russian Internet because she posts a lot of pictures on her blog..{T; F}
4. The author thinks Valeria neither Photoshops her, nor accepts a series of plastic surgery.{T; F}
5. The president of ASPS thinks that plastic surgery is of risks.{T; F}
Gordon Shaw the physicist, 66, and colleagues have discovered what's known as the “Mozart effect”, the ability of a Mozart sonata, under the right circumstances, to improve the listener's mathematical and reasoning abilities. But the findings are controversial and have launched all kinds of crank notions about using music to make kids smarter. The hype, he warns, has gotten out of hand.
But first, the essence: Is there something about the brain cells work to explain the effect? In 1978 the neuroscientist Vernon Mountcastle devised a model of the neural structure of the brain's gray matter. Looking like a thick band of colorful bead work, it represents the firing patterns of groups of neurons. Building on Mountcastle, Shaw and his team constructed a model of their own.
On a lark, Xiaodan Leng, who was Shaw's colleague at the time, used a synthesizer to translate these patterns into music. What came out of the speakers wasn't exactly toe-tapping, but it was music. Shaw and Leng inferred that music and brain-wave activity are built on the same sort of patterns.
“Gordon is a contrarian in his thinking,” says his longtime friend, Nobel Prize-winning Stanford physicist Martin Peri. “That's important. In new areas of science, such as brain research, nobody knows how to do it.”
What do neuroscientists and psychologists think of Shaw's findings? They haven't condemned it, but neither have they confirmed it. Maybe you have to take them with a grain of salt, but the experiments by Shaw and his colleagues are intriguing. In March a team led by Shaw announced that young children who had listened to the Mozart sonata and studied the piano over a period of months improved their scores by 27% on a test of ratios and proportions. The control group against which they were measured received compatible enrichment courses-minus the music.
The Mozart-trainedkids are now doing math three grade levels ahead of their peers, Shaw claims.
Proof of all this, of course, is necessarily elusive because it can be difficult to do a double-blind experiment of educational techniques. In a double-blind trial of an arthritis drug, neither the study subjects nor the experts evaluating them know which ones got the test treatment and which a dummy pill. How do you keep the participants from knowing it's Mozart on the CD?
61.In the first paragraph Gordon Shaw's concern is shown over______.
A.the open hostility by the media towards his findings
B.his strength to keep trying out the “Mozart effect”
C.a widespread misunderstanding of his findings
D.the sharp disagreement about his discovery

A.listening to Mozart could change the brain's hardware
B.brain-waves could be invariably translated into music
C.listening to music could stimulate brain development
D.toe-tapping could be very close to something musical
63.The remarks made by Martin Perk in Paragraph 3 about Gordon Shaw could be taken as______.
A.a compliment
B.an outspoken criticism
C.an expression of jealousy
D.something a little sarcastic
64.In the sentence “Maybe you have to take them...” (Para. 4) the word “them” best refers to______.
A.neuroscientists and psychologists
B.Shaw and his colleagues
C.the experiments by Shaw and his team
D.Shaw's findings
65.The most important condition for the Mozart-trained kids to outsmart the control group is______.
A.being particularly trained to tackle math problems

A.the control group will also enjoy the same kind of Mozart
B.some educational techniques need re-evaluation
C.the double-blind experiment is not reliable and thus rejected by Shaw
D.participants cannot be kept from knowing what is used in the test
听力原文: When you see a clever advertisement in a newspaper, do you say to yourself, "Ah, that's good. I'd like to have one of those"? Or do you say, "What lies are they telling this time? It can't be very good or they wouldn't have to advertise it so cleverly"? Both of these people exist; the first are optimists; the second, pessimists and realists.
Advertisements can be extremely useful if they are honest; if, let us say, you have broken your pen and you want to buy another, the first thing to do is to look at as many advertisements for pens as you can find. That will help you to choose the model, color and price that suit you. Advertisements save a lot of time and trouble by putting sellers in touch with buyers in a quick and simple way. If the advertisements are true and accurate, the customers will be satisfied and will probably buy from the same firm next time and advise their friends and acquaintances to do the same.
The really dishonest advertiser hopes to sell his goods quickly and to make a large profit on them before the customer's reactions begin. He knows that no customers will buy from him a second time, and that none will recommend his products to their friends. But there are also semi-dishonest advertisers. They make claims for their products which they know perfectly well to be incapable of verification, like advertising that a certain toothpaste contains a particular substance—which it in fact does—knowing that this substance is in fact neither beneficial nor harmful to the teeth. Such advertisements do not tell downright lies, but their advertising is deliberately misleading.
(30)
A.Trust all advertisements and make purchases accordingly.
B.Get suitable colors and prices from advertisements.
C.Doubt the truthfulness of advertisements.
D.Admire the clever ways advertisements are made.
Generations of writers on management have recognized that some practicing managers rely heavily on intu- ition. In general, however, such writers display a poor grasp of what intuition is. Some see it as the opposite of rationality; others view it as an excuse for capriciousness.
Isenberg’s recent research on the cognitive processes of senior managers reveals that managers' intuition is neither of these. Rather, senior managers use intuition in at least five distinct ways. First, they intuitively sense when a problem exists. Second, managers rely on intuition to perform. well-learned behavior. patterns rapidly. This intuition is not arbitrary or irrational, but is based on years of painstaking practice and hands-on experience that build skills. A third function of intuition is to synthesize isolated bits of dar8 and practice into an integrated picture, often in an "Aha" experience. Fourth, some managers use intuition as a check on the results of more rational analysis. Most senior executives are familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally leery of solutions suggested by these methods which run counter to their sense of the correct course of action. Finally, managers can use intuition to bypass in-depth analysis and move rapidly to engender a plausible solution. Used in this way, intuition is an almost instantaneous cognitive process in which a manager recognizes patterns.
One of the implications of the intuitive style. of executive management is that "thinking" is inseparable from acting. Since managers often "know" what is right before they can analyze and explain it, they frequently act first and explain later. Analysis is inextricably tied to action in thinking/acting cycles, in which managers develop thoughts about their companies and organizations not by analyzing a problematic situation and then acting, but by acting and analyzing in close concert.
The classical model of decision analysis includes all EXCEPT
A.evaluation of a problem.
B.establishment of clear goals to be reached by the decision.
C.action undertaken in order to discover more information about a problem.
D.comparison of the probable effects of different solutions to a problem.
So, how old is old? The answer is one you' ve heard many times, from all sorts of people. "You are as old (or young) as you feel." The calendar simply tells you how many years you have lived. Your body tells you how well you' ve lived.
"Youth", wrote an unknown author, "is not a time of life--it is a state of mind. Nobody grows old by living a number of years; people grow old by deserting (抛弃) their ideals."
Old is a point of view. Alice Brophy, when she was with the New York City Commission for the Aging, said, "It annoys me when people say, 'Gee, you look young for your age. ' What does that mean? Is there some model that you' re supposed to look a certain way at 65 and 75 and 85? You know, you can die old at 30 and live young at 80."
It is often believed that most older people are in poor health. But the fact is that there are neither biological nor physiological (生理学的) reasons to connect poor health with growing older. Older people are more likely to be affected with illness and physical disabilities than you are, but old age itself is not a disease. It's possible to remain physically fit throughout your life.
Which of the following statements is NOT true according to the passage?
A.The concept of "old" is differently defined in different times.
B.Nobody can remain physically healthy throughout the life.
C.The progress in medical knowledge has contributed a lot lo longer lives of us.
D.Older people may get ill and physically disabled more easily than younger ones.
I suggest we think of ethics as analogous to language usage. There are no univocal rules of grammar and style. which uniquely determine the best sentence for a particular situation. Nor is language usage universalizable. Although a sentence or phrase is warranted in one case, it does not mean it is automatically appropriate in like circumstances. Nonetheless, language usage is not subjective.
This should not surprise us in the least. All intellectual pursuits are relativistic in just these senses. Political science, psychology, chemistry, and physics are not certain, but they are not subjective either. As I see it, ethnical inquiry proceeds like this: we are taught moral principles by parents, teachers, and society at large. As we grow older we become exposed to competing views. These may lead us to reevaluate presently held beliefs. Or we may find ourselves inexplicably making certain valuations, possibly because of inherited altruistic tendencies. We may "learn the hard way" that some actions generate unacceptable consequences. Or we may reflect upon our own and others' "theories" or patterns of behavior. and decide they are inconsistent. The resulting views are "tested"; we act as we think we should and evaluate the consequences of those actions on ourselves and on others. We thereby correct our mistakes in light of the test of time.
Of course people make different moral judgments; of course we cannot resolve these differences by using some algorithm which is itself beyond judgment. We have no vantage point outside human experience where we can judge right and wrong, good and bad. But then we don't have a vantage point from where we can be philosophical relativists either.
We are left within the real world, trying to cope with ourselves, with each other, with the world, and with our own fallibility. We do not have all the moral answers, nor do we have an algorithm to discern those answers, neither do we possess an algorithm for determining correct language usage but that does not make us throw up our hands in despair because we can no longer communicate.
If we understand ethics in this way, we can see, I think, the real value of ethical theory. Some people talk as if ethical theories give us moral prescriptions. They think we should apply ethical principles as we would a poultice: after diagnosing the ailment, we apply the appropriate dressing. But that is a mistake. No theory provides a set of abstract solutions to apply straightforwardly. Ethical theories are important not because they solve all moral dilemmas but because they help us notice salient features of moral problems and help us understand those problems in context.
Ethical principles are generally thought to be ______.
A.explicitly clear
B.implicitly vague
C.certain but non-rational
D.relative but not subjective
a.在消费者第一期消费小于第一期收入的情况下,消费者的预算制约是什么?
b.在消费者第一期消费大于第一期收入的情况下,消费者的预算制约是什么?
c.画出两条预算制约线以及代表消费者可以选择的第一期与第二期消费组合的阴影面积。
d.现在加上你画的消费者无差异曲线。说明三种可能的结果:一种是消费者有储蓄,另一种是消费者有借贷,而第三种是消费者既无储蓄又无借贷。
e.什么决定了这三种情况中每一种情况下的第一期消费。
The chapter analyzes Fisher's model for the case in which the consumer can save or borrow at an interest rate of r and for the case in which the consumer can save at this rate but cannot borrow at all. Consider now the intermediate case in which the consumer can save at rate rsand borrow at rate rb, where rs<rb.
a.What is the consumer's budget constraint in the case in which he consumes less than his income in period 0ne?
b.What is the consumer's budget constraint in the case in which he consumes more than his income in period one?
c.Graph the two budget constraints and shade the area that represents the combination of first-period and second-period consumption the consumer can choose.
d.Now add to your graph the consumer's indifference curves. Show three possible outcomes: one in which the consumer saves, one in which he borrows, and one in which he neither saves nor borrows.
e.What determines first-period consumption in each of the three cases?
The reasons for Disney's success are quite a lot, but ultimately the credit belongs to one person - the man who created the cartoon and built the company from nothing, Walt Disney. Ironically, he could not draw particularly well. But he was a genius in other aspects. In business, his greatest skills were his insight and his management ability. After setting himself up in Hollywood, he single-handedly pioneered the concepts of branding and merchandising -- something his company still does brilliantly today.
But what really distinguished Disney was his ability to identify with his audiences. Disney always made sure that his films portrayed the "little boy". He achieved this by creating characters that reflected the hopes and fears of ordinary people.
Disney's other great virtue was the fact that his company -- unlike other big corporations had a human face. His Hollywood studio -- the public heard -- operated just like a democracy, where everyone was on first-name terms and had a say in how things should be run. He was also regarded as a great patriot because not only did his cartoons praise America, but, during World War II, his studios made training films for American soldiers.
The reality, of course, was not so perfect. As the public would later learn, Disney's patriotism had an unpleasant side. After a strike by cartoonists in 1941, he agreed to work for the FBI secretly, identifying and spying on colleagues who he suspected were anti-government.
But, apart from his affiliations with the FBI, Disney was more or less the genuine article. A new book, The Magic Kingdom: Walt Disney and the American Way of Life, confirms that he was very definitely on the side of ordinary people. In the 30s and 40s he voted for Franklin Roosevelt, believing he was a leader of the workers. Also, Disney was not an apologist for the FBI, as some have suggested. In fact, he was suspicious of large, bureaucratic organizations, as is evidenced in films like That Darned Cat.
By the time he died in 1966, Walt Disney was as famous as Thomas Edison and the Wright Brothers. To business people and filmmakers, he was a role model; to the public, he was "Uncle Walt" -- the man who had entertained them all their lives, the man who represented all that was good about America.
Walt Disney is believed to possess the following abilities EXCEPT
A.painting.
B.creativity.
C.management.
D.merchandising.
