This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise. And as a result, we are aging unnecessarily soon.The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, doctors say, are lawyers,followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brain as the farm worker, bus driver and shop assistant.Doc tors’ findings also show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain”, they say, “Think hard and engage in conversation. Don’t rely on pocket calculators.”Part D: Literary AppreciationThe Catcher in the Rye1.By saying "you don't like anything that's happening", Phoebe means that Holden is angryabout the world but he doesn't know how to deal with the problems. He fails to win recognition from people around him and he himself regards the outside world as corrupted with phony people. Phoebe points out his problem and makes Holden more depressed.2.James Castle, Holden's schoolmate, was maltreated by six students in the same school andfinally jumped down from the window. The six students were not punished. Holden regards this as persecution of the corrupted and phony society over innocent youth. He becomes very depressed.3.Holden is extremely disappointed with the present situation, so he cannot find anything goodin the real life. All he can see around him is violence, cheating and corruption, so he can only cherish a dream.4.He thinks the adult world is disgusting with cheating and corruption. He hates it and is afraidof entering it, so finally he goes mad.5.Holden's dream is to be "a catcher in the rye, protecting innocent children from falling off thecliff". That is to protect the innocent children from the persecution of the corrupted adult world.6.Phoebe is innocent, clever, considerate and pretty. So he may be the ideal child Holden wantsto protect from the corruption of the adult world in his dream.7.Maybe not. It is related to the character traits of Holden. Besides, the outside world is sopowerful and overwhelming.8.Holden is described as a rebel of the modern world. He is sensitive enough to see all thecorruption, meaninglessness, hypocrisy of the society, but he can find no way to change the situation. So finally he is sent to a mental hospital.Unit SevenReading Selection One:Electric Tales –21st Century BooksBy Frank VizardIt may be the last book you'll ever buy. And certainly, from a practical standpoint,it will be the only book you'll ever need. No, it's not the Bibleor some New Age tome promising enlightenment—although itwould let you carry around both texts simultaneously. It's anelectronic book—a single volume that could contain a libraryof information or, if your tastes run toward what's current,every title on today's best-seller list.* And when you're done with those, you could refill it with new titles.TWhy an electronic book? Computers can store a ton of data and their laptop companions make all that information portable. True enough. But laptops and similar portable information devices require a lot of power—and heavy batteries—to keep their LCD screens operating. And LCDs are not easy to read in the bright light of the sun. TFact is, when it comes to portability, easy viewing, and low power requirements, it's hard to beat plain old paper.*TSo let's make the ink electronic.TThat's the deceptively simple premise behind a project currently coming to fruition at the Massachusetts Institute of Technology.* Some hurdles —mostly having to do with large-scale manufacturing—remain, so it will be a few years before you see an electronic book for sale in stores. But the basic technology already exists, developed at the Institute's Media Lab by a team led by physicist Joe Jacobson.T Simply put, each paper page in an electronic book is coated with millions ofmicroscopic particles encased in tiny capsules. Each of these microcapsules can respond independently to an electrical charge: Particles within the capsule moving to the rear appear dark while those moving toward the front look white. The direction in which the particles move depends upon whether a negative (dark) or positive (white) charge is applied. Each microcapsule is about 40 microns in size (that's a little less than half the thickness of a human hair).TThe number of microcapsules used on a given page is enormous. For instance, about 1, 000 microcapsules might be used to create the letter "A" on this page. "The smaller the size of the letter the more microcapsules you use," says Jacobson, "thereby improving resolution." The target is to have a "Paper display" with a resolution higher than that offered by today's computer screens. More than static letters is at stake. Theoretically, the microcapsules could be programmed to "flip" rapidly between dark and white state, providing, for example, a sense of motion in a diagram showing how a car works.TThanks to electronic ink, the book essentially typesets itself, receivinginstructions for each page via electronics housed in the spine. From a power standpoint, this process makes the electronic book very efficient. Unlike an LCD screen, which uses power all the time, energy is no longer needed to view the electronic book's pages once they are typeset. Only a small battery would be required, as opposed to the large ones needed to power laptop computers and their LCDs.*T Convenience, though, is still the main attraction—and that means more than simple portability.* Because the information is in electronic form, it can be easily manipulated. You could, for instance, make the type larger for easier reading. Or you could make notes in the margin with a stylus, your observations being stored on tiny, removable flash-memory cards in the spine.TIt's likely that electronic books will come pre-loaded with a selection of titles. New titles could be made available through flash-memory cards, for example. Jacobson, though, thinks the Internet will be the delivery method of choice. Imaginebrowsing through an online bookstore like and downloading a novel into your electronic book via the modem in its spine. Transmitting Moby Dick would take about a minute. You could download a few titles, so you'll have a few good reads to choose from while you're relaxing at the beach. If your first choice is not to your liking, a new title becomes available at the push of a button.*T Jacobson thinks an electronic book will be affordable—around $200 for a basic read-only model to about $400 for one that would record your margin scribbles. Some hurdles remain, though, before you can take an electronic book with you anywhere. Paper is produced in long sheets, and Jacobson is still working on the best method to integrate electronic ink into the process. To avoid having to use thousands of tiny wires on each page, the ink itself must be conductive. Such ink was recently demonstrated in the lab but has yet to be produced in volume. "Essentially," notes Jacobson, "we're trying to print chips." TJacobson is confident, however, that this can be done on a large scale. If Jacobson succeeds, he will have made the books for the 21st century.

Increases in road traffic in countries such as China will be even more dramatic, as new mass markets develop.TElectric and gas-powered vehicles will become a reasonably common sight, particularly in big cities and among public service fleets, and car engines will be more efficient and cleaner than they are now.TMost cars will still be built from steel, although smaller and more efficient cars will be encouraged, probably through subsidies and preferential tax rates. Some cities will introduce smaller car parking bays on their streets and others may ban bigger cars altogether. Many inner-city areas will become off limits to all cars, and cities will probably increase dramatically the cost of parking within city limits.*T Many countries will ask car buyers to prove they have somewhere suitable to park their vehicle, and introduce "smart highway" systems to direct cars much as air traffic controllers now look after the flight of aeroplanes.THowever, despite a dramatic call from environmentalists for radical changes in the way cars are designed and built, a survey of international car manufactures by a British research company foresees a continuation of current trends—a move towards more efficient petrol-engined cars, a slight upswing in the use of diesel cars, and a gradual move to electric and gas-powered cars.TThe Warranty Holdings Group, a European leader in mechanical breakdown insurance and a researcher and commentator on trend in motoring, says that the motorists' world 20 years from now will be marked by more cars, more choice and more technology. Built-in safety features will increase and will include night-vision and collision-avoidance systems, and monitoring devices to stop drivers falling asleep at the wheel.TA growth in tele-working and home shopping should cut the numbers of trips in a car made by most motorists and "fun" sportscars will become more popular as private motoring becomes more recreational in nature.TThe survey results show that despite years of research into alternative fuel sources for vehicles, no clear winner has emerged for a replacement for the conventional petrol-engined car.* Gas and electricity are the best possibilities, with Toyota's design division in Japan claiming it already has an electric car that will driveup to 250km on a single charge.THowever, while electric and "hybrid" powered vehicles will be far more in evidence in the future, it will take a major technological break-through to steer the car industry away from its current path of gradual improvements to the petrol-driven internal combustion engine.TProfessor Garel Rhys, of the Cardiff Business School in Wales, is a leading commentator on the global motor industry. He says engine fuel injection systems of the future will be far more frugal than anything that exists at the moment. "It will be like putting a pipette of petrol into the cylinders, rather than just throwing it in by the bucket load, which is almost what we do at the moment when you compare it with what could be possible." TSome environmentalists point to the Twingo, the small car developed by France's Renault company, to show what could be achieved by the world's car industry if it moved away from a trend towards bigger and more powerful cars and radically cut the fuel consumption of its products. Public opinion polls in many countries show motorists wanting access to this kind of environmentally-aware car.*TA prototype environmental car, the SmILE (smaller, intelligent, lighter, efficient) has been put together by the environmental group Greenpeace. The group hopes the concept will catch on.* It depends heavily on supercharging or forcing fuel mixture into the cylinders at higher than normal pressure. Some experts say this is a good way to extract high performance and high fuel efficiency from small engines.T The adaptations to the Twingo don't end with the engine.* Changes to the bodywork and chassis have improved aerodynamics by 30 per cent in the wind tunnel. Special lightweight rims and tyres have improved rolling resistance by 35 per cent. More than 196kg of weight was trimmed off the Twingoby the smaller engine and a lighter radiator, battery andexhaust system, as well as by changes in construction ofthe seats, suspension, brakes and petrol tank. Greenpeacebelieves another 80kg could be trimmed from the car'sweight by a comprehensive rebuilding of the body of acar like Twingo, using fibre composites, without affectingthe vehicle's safety standards. While glass fibre andcarbon fibre reinforced plastic parts were used for the more aerodynamic body parts, the SmILE designers say they were built in such a way that using steel would make no difference to the total weight.TCutting the fuel consumption has had no negative effect on the handling or performance of the car,* according to the designers. Top speed, flexibility and acceleration from the engine is as good or better than the original Twingo. They say the technology used to create the Twingo SmILE could just as easily be used on other brands of car.TWhat remains to be seen is whether the enthusiasm of environmental designers catches on with the dollar-driven international car industry,* and whether motorists back up with their chequebooks their desire for "greener" cars.T。

Unit 7I’d Rather Be Black than FemaleConsolidation ActivitiesI. Text Comprehension1. Decide which of the following best states the author's purposeA.To present a picture of American women who are prejudiced against in politics andemployment.B.To reveal the difficulties she encountered when running for Congress as a black female.C.To call for the removal of prejudice against women by relating her own experiences and somecommon social phenomena.Key: [ C ]2. Judge, according to the text, whether the following statements are true or false.1). The author implies that American people, both men and women, are not so readily aware of the existence of prejudice against women as that against blacks. [ T ]2). The long, tedious and faithful political work can guarantee a woman a dominant position in politics. [ F ]3). The author’s experiences of running for office indicate that her every attempt to go upward in politics was met with men’s strong disapproval. [ T ]4). Although women suffer prejudice in job recruitment, they still enjoy the same opportunities as men in career development. [ F ]5). According to the author, her major responsibility in politics is to affirm the role of women in the country. [ T ]II. Writing StrategiesThe title of the pass age seems to suggest that the article is mainly about the author’s personal experiences in politics. But careful readers will find that the author integrates such experiences into the general situation of women, which is more poignant than the racial problem, thus intensifying and broadening the theme.The author mainly employs three devices: comparison, rhetorical questions and parallelism. Comparison is used between blacks and females, both of whom suffer prejudices, and between men and women for their respective roles in politics and for their career opportunities; rhetorical questions and parallelism are used to highlight the emotive force of the passage.Now you are required:1. to differentiate the author’s personal experiences from the general situa tion of women;2. to identify and study the rhetorical questions and parallelisms used in the passage.Key:1. The author’s personal experiences: Paragraphs 1, 5, 7, 8, 9, 13.The common situation of women: Paragraphs 2, 4, 6, 10, 11, 15.2. Rhetorical questions: Paragraphs 2, 4, 10, 12.Parallelisms: Paragraph 15.III. Language Work1. Explain the underlined part(s) in each sentence in your own words.1).

Extra word: delete the extra word with an “×.”Missing word: mark the position of the missing word with a “∧” and write the missing word in the blank.Glass Ceiling I’ve received a lot of questions lately during seminars to ask if I think there is a glass ceiling beyond the top of the corporate ladder that blocks successful women from achieving the highest rungs. According to an article in the Harvard Business Review by Alice H. Eagly and Linda L. Carli, the answer is “No.” However, the sum of many obstacles along the way often holding women back from making it into the C-suite. Carol Hymowitz and Timothy D. Schellhardt were the first to use the term “glass ceiling” on their March 24, 1986 article in the Wall Street Journal, “The Glass Ceiling: Why Women Can’t Seem to Break the Invisible Barrier That Blocks Them from the Top Job.” The term resonated to women around the world because it captured our frustrations — and the term “glass ceiling” has now become commonplace. However, Eagly and Carli believe a better metaphor for what confronts women in their careers is the term “labyrinth” because it “conveys the idea of a complex journey toward a goal worth striving for. Passage through a labyrinth is not simple or direct, but requires persistence, aware of one’s progress, and a careful analysis of the the puzzles that lie ahead.” How can you make your way to the career labyrinth? According to Eagly and Carli, women need to better understand the barriers that make of the labyrinth, determine how successful women find ways around these barriers, and then attack all barriers to advancement simultaneously.(1) beneath(2) holds(3) in(4) with(5) awareness(6) through(7) up6. Fill in each blank in the passage below with ONE appropriate word.The Female’s ChoiceScientists (1) studying how females choose their mates have found many similarities between species, (2) including humans. It seems that females in most species prefer to mate with flashy males — the most brightly colored, or (3) those with the most lively courtship displays.Females generally shop around for their mates, sometimes comparing them on the spot in groups, or more commonly, one at a time. Scientists have shown that female fish are (4) able to remember and compare the characteristics of males presented separately. The females showed more interest if one male was more colorful than the one before him.(5) Whether the females are fish or birds, they generally choose the most colorful male, or the one who (6) stands out in some way. With tree frogs, it is the male that can call the loudest and most often. With ducks, it is the males that court the females most often.In some species, the female prefers males that can (7) provide some direct benefit, such as food or protection. If males do not provide such obvious benefits, females may choose the males with the best genes. They measure this by the males’ fitness. Female guppies, for example, seem to prefer bold males — those that will swim closest to a predator fish. Because the more colorful males seem to have more courage, females have developed a preference for (8)colorful males.Recent evidence indicates that social factors can also influence the female's choice. In many species, females seem to be more interested in males that already have other (9) females. Scientists call this “copying,” and (10) younger females are more likely to copy older females than the opposite. Older females seem to know what they want. But younger females seem to be more willing to follow the crowd.Perhaps this accounts for the popular expression “Some guys get all the girls.”IV. Translation1.
