b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Question 1——10
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ The word laser was coined as an acronym for Light Amplification by the Stimulated
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Emission of Radiation. Ordinary light, from the Sun or a light bulb, is emitted
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ spontaneously, when atoms or molecules get rid of excess energy by themselves, without
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ any outside intervention . Stimulated emission is different because it occurs when an
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ atom or molecule holding onto excess energy has been stimulated to emit it as light.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Albert Einstein was the first to suggest the existence of stimulated emission in a
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ paper published in 1917. However , for many years physicists thought that atoms and
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ molecules always were much more likely to emit light spontaneously and that stimulated
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ emission thus always would be much weaker. It was not until after the Second World
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ War that physicists began trying to make stimulated emission dominate. They sought
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ ways by which one atom or molecule could stimulate many other to emit light ,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ amplifying it to much higher powers.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ The first to succeed was Charles H.Townes, then at Colombia University in New
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ York . Instead of working with light , however, he worked with microwaves, which have
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ a much longer wavelength, and built a device he called a "maser" for Microwave
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Amplification by the Stimulated Emission of Radiation. Although he thought of the
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ key idea in 1951, the first maser was not completed until a couple of years later. Before
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ long, many other physicists were building masers and trying to discover how to produce
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ stimulated emission at even shorter wavelength.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ The key concepts emerged about 1957. Townes and Arthur Schawlow, then at Bell
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Telephone Laboratories, wrote a long paper outlining the conditions needed to amplify
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ stimulated emission of visible light waves. At about the same time, similar ideas
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ crystallized in the mind of Gordon Gould, then a 37- year-old graduate student at
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Columbia, who wrote them down in a series of notebooks. Townes and Schawlow
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ published their ideas in a scientific journal, Physical Review Letter, but Gould filed a
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ patent application. Three decades later, people still argue about who deserves the credit
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ for the concept of the laser.

b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Question 11——21
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Panel painting, common in thirteenth -and fourteenth -century Europe , involved a
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ painstaking , laborious process. Wooden planks were joined, covered with gesso to
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ prepare the surface for painting , and then polished smooth with special tools. On this
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ perfect surface, the artist would sketch a composition with chalk, refine it with inks,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ and then begin the deliberate process of applying thin layers of egg tempera paint (egg
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ yolk in which pigments are suspended) with small brushes. The successive layering of
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ these meticulously applied paints produced the final, translucent colors.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Backgrounds of gold were made by carefully applying sheets of gold leaf, and then
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ embellishing of decorating the gold leaf by punching
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ it with a metal rod on which a
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ pattern had been embossed. Every step in the process was slow and deliberate . The
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ quick-drying tempera demanded that the artist know exactly where each stroke be
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ placed before the brush met the panel, and it required the use of fine brushes. It was,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ therefore , an ideal technique for emphasizing the hard linear edges and pure, fine areas
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ of color that were so much a part of the overall aesthetic of the time. The notion that an
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ artist could or would dash off an idea in a fit of spontaneous inspiration was
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ completely alien to these deliberately produced works.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Furthermore, making these paintings was so time-consuming that it demanded
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ assistance. All such work was done by collective enterprise in the workshops. The
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ painter or master who is credited with having created painting may have designed
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ the work and overseen its production, but it is highly unlikely that the artist’s hand
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ applied every stroke of the brush. More likely, numerous assistants, who had been
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ trained to imitate the artist’s style, applied the paint. The carpenter’s shop probably
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ provided the frame and perhaps supplied the panel, and yet another shop supplied the
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ gold. Thus, not only many hands , but also many shops were involved in the final
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ product.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ In spite of problems with their condition, restoration, and preservation many panel
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ paintings have survived, and today many of them are housed in museum collections

b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæQuestion 22——32
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Crows are probably the most frequently met and easily identifiable members of the
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ native fauna of the United States . The great number of tales, legends, and myths about
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ these birds indicates that people have been exceptionally interested in them for a long
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ time. On the other hand, when it comes to substantive —— particularly behavioral ——
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ information, crows are less well known than many comparably common species and,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ for that matter, not a few quite uncommon ones: the endangered California condor, to
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ cite one obvious example. There are practical reasons for this.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Crows are notoriously poor and aggravating subjects for field research. Keen
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ observers and quick learners, they are astute about the intentions of other creatures,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ including researchers, and adept at avoiding them. Because they are so numerous,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ active, and monochromatic, it is difficult to distinguish one crow from another. Bands,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ radio transmitters, or other identifying devices can be attached to them , but this of
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ course requires catching live crows, who are among the wariest and most untrappable
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ of birds.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Technical difficulties aside , crow research is daunting because the ways of these
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ birds are so complex and various. As preeminent is generalists, members of this species ingeniously exploit a great range of habitats and resources, and they can quickly adjust
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ to changes in their circumstances. Being so educable, individual birds have markedly
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ different interests and inclinations, strategies and scams.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ For example, one pet crow
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ learned how to let a dog out of its kennel by pulling the pin on the door. When the dog
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ escaped, the bird went into the kennel and ate its food.

b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ In the early days of the United States, postal charges were paid by the recipient and
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Charges varied with the distance carried. In 1825, the United States Congress permitted
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ local postmasters to give letters to mail carriers for home delivery, but these carriers
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ received no government salary and their entire compensation depended on what they
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ were paid by the recipients of individual letters.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ In 1847 the United States Post Office Department adopted the idea of a postage stamp,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ which of course simplified the payment for postal service but caused grumbling by
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ those who did not like to prepay. Besides, the stamp covered only delivery to the post
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ office and did not include carrying it to a private address. In Philadelphia, for example,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ with a population of 150,000, people still had to go to the post office to get their mail.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ The confusion and congestion of individual citizens looking for their letters was itself
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ enough to discourage use of the mail. It is no wonder that, during the years of these
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ cumbersome arrangements, private letter-carrying and express businesses developed.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Although their activities were only semilegal, they thrived, and actually advertised that
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ between Boston and Philadelphia they were a half-day speedier than the government
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ mail. The government postal service lost volume to private competition and was not
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ able to handle efficiently even the business it had.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Finally, in 1863, Congress provided that the mail carriers who delivered the mail
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ from the post offices to private addresses should receive a government salary, and that
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ there should be no extra charge for that delivery. But this delivery service was at first
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ confined to cities, and free home delivery became a mark of urbanism. As late as 1887,
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ a town had to have 10,000 people to be eligible for free home delivery. In 1890, of the
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 75 million people in the United States, fewer than 20 million had mail delivered free
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ to their doors. Th e rest, nearly three-quarters of the population, still received no mail
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæunless they went to their post office.

b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Questions 43-50
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Archaeology has long been an accepted tool for studying prehistoric cultures.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Relatively recently the same techniques have been systematically applied to studies of
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ the more immediate past. This has been called "historical archaeology," a term that is
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ used in the United States to refer to any archaeological investigation into North
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ American sites that postdate the arrival of Europeans.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ Back in the 1930’s and 1940’s, when building restoration was popular, historical <
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ br>archaeology was primarily a tool of architectural reconstruction. The role of archaeologists
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ was to find the foundations of historic buildings and then take a back seat to architects.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ The mania for reconstruction had largely subsided by 1950’s. Most
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ people entering historical archaeology during this period came out of university
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ anthropology departments., where they had studied prehistoric cultures. They were, by
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ training, social scientists, not historians, and their work tended to reflect this bias. The
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ questions they framed and the techniques they used were designed to help them
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ understand, as scientists, how people behaved. But because they were treading on
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ historical ground for which there was often extensive written documentation and because
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ their own knowledge of these periods was usually limited, their contributions to American
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ history remained circumscribed. Their reports, highly technical and sometimes poorly
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ written, went unread.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæMore recently, professional archaeologists have taken over. These researchers have
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ sought to demonstrate that their work can be a valuable tool not only of science but also
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ of history, providing fresh insights into the daily lives of ordinary people whose existences
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ might not otherwise be so well documented. This newer emphasis on archaeology as
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ social history has shown great promise, and indeed work done in this area has lead to a reinterpretation of the United States past.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ In Kingston, New York, for example, evidence has uncovered that indicates that
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ English goods were being smuggled into that city at a time when the Dutch supposedly
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ controlled trading in the area. And in Sacramento an excavation at site of a fashionable nineteenth-century hotel revealed that garbage had been stashed in the building’s
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ basement despite sanitation laws to the contrary.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 42. What does the passage mainly discuss?
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (A) Why historical archaeology was first developed
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (B) How the methods and purpose of historical archaeology have changed
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (C) The contributions architects make to historical archaeology
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (D) The attitude of professional archaeologists toward historical archaeology
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 43. According to the first paragraph., what is a relatively new focus in archaeology?
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (A) Investigating the recess past
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (B) Studying prehistoric cultures
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (C) Excavating ancient sites in what is now the United States.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (D) Comparng ancient sites in what is now the United States.
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 44. According to the passage, when had historical archaeologists been trained as anthropologists? (A) Prior to the 1930’s
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (B) During the 1930’s and 1940’s
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (C) During the 1950’s and 1960’s
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (D) After the 1960’s
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 45. The word "framed" in line 13 is closest in meaning to

b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 46. In the third paragraph, the author implies that the techniques of history and the techniques of social science are
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (A) quite different from each other
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (B) equally useful in studying prehistoric cultures
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (C) usually taught to students of archaeology
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ (D) both based on similar principles
b¡s¼Gÿ4Åforum.liuxuehome.com#ÉñÇæ 47. The phrase "their contributions" in line 16 refers to the contributions of
