Part III. Reading Comprehension (30 points)
Directions
There are 6 passages in this pail. Each Passage is followed by some questions or unfinished statements. Each question or unfinished statement is given four suggested answers marked A), B), C) and D). You should choose the one best answer and write the corresponding letter on the Answer Sheet.
Passage One
Some of the earliest diamonds known came from India. In the eighteenth century they were found in Brazil, and in 1866, huge deposits were found near Kimberley in South Africa. Though evidence of extensive diamond deposits has recently, been found in South Africa, the continent of Africa still produces nearly all the world's supply of these stones.
The most valuable diamonds are large, individual crystals of pure crystal lint carbon. Less perfect forms, known as 'boars' and 'carbonado' arc clusters of tiny crystals. Until diamonds are cut and polished, they do not sparkle lice those you sec on a ring--they just look like small, blue-grey stones.
In a rather crude form the cutting and polishing of precious stones was an art known to the Ancient Egyptians, and in the Middle Ages it became 1Lidcspread iii north-west Europe. However, a revolutionary change in the methods of cutting and polishing was made in 1476 when Ludwig Van Berquen of Bruges in Belgium invented the use of a swiftly revolving wheel with its edge faced with fine diamond powder. The name 'boast' is given to this fine powder as well as the natural crystalline material already mentioned. It is also gimp to badly flawed or broken diamond crystals, useless as jewels, that are broken into powder for grinding purposes, the so-called `industrial' diamonds.
Diamond itself is the only material hard enough to cut and polish diamonds--though recently, high-intensity light beams called lasers have been developed which can bore holes in them. It may be necessary to split or cleave the large stones before they arc cut and polished. Every diamond has a natural line of cleavage, along which it may be split by a sharp blow with a cutting edge.
A fully cut 'brilliant' diamond has 58 facets, or faces, regularly arranged. For cutting or faceting, the stones arc fixed into copper holders and held against a wheel, edged with a mixture of Oil and fine diamond dust, which is revolved at about 2,500 revolutions a minute. Amsterdam and Antwerp, in Holland and Belgium respectively, have been the centre of the diamond cutting and polishing industry for over seven centuries.
The jewel value of brilliant diamonds depends greatly on their colour, or `water' as it is called. The usual colours of diamonds are white, yellow, brown, green or blue- Surrounding rocks and take on their color. thus black ,red and even bright pink diamonds have occasionally been found.
The trade in diamonds Is not only in the valuable gem stones but also in the industrial diamonds mentioned above. Zaire produces 70% of such stones. They are fixed into the rock drills used in mining and civil engineering, also for edging band saws for cutting stone. Diamond-faced tools are used for cutting and drilling glass and fine porcelain and for dentists' drills. They are used as bearings in watches and other finely balanced instruments. Perhaps you own some diamonds without knowing it--in your wristwatch!
71. 'Carbonado' is the name given to
A) only the very best diamonds B) lumps of pure carbon
C) Spanish diamonds D) diamonds made up of many small crystals
72. The art of cutting and polishing precious stones remained crude until
A) the fourteenth century B) the fifteenth century
C) the sixteenth century D) the seventeenth century
73. During faceting, diamonds are held in copper holders
A) to facilitate accurate cutting B) to make them shine more brilliantly
C) so that they can revolve more easily D) as a steel holder might damage the diamond
74. The value order of `water' in diamond, _
A) is more important than their colour B) ranges from blue-white upwards
C) ranges from blue-white downwards D) has never been reliably established
75. Industrial diamonds are used
A) for a wide range of purposes B) mainly for dentists' drills
C) for decoration in rings and watches D) principally in mass-produced jewellery
Passage Two
Just about everyone knows the meaning of `value" though you'd never know it from the excesses of the Eighties. Clever campaigns often allowed marketers to charge more for their product and reap ever-higher profits. It worked like a dream until suddenly, facing difficult economic times, consumers work up. Now, to the extent that they're buying, many consumers are choosing the car that delivers the most for the money--not necessarily the one they coveted as a status symbol a few years ago, they are shifting to the toothpaste that works from the ones with it slickest promotions. Companies that understand this new consumer have come up wit something new: "value marketing".
A word of caution is necessary. In marketing, watchwords quickly metamorphos into buzzwords--and value is no exception. We're not taping about ads that merely boast of a product's value or even such legitimate sates tools as price cuts and discount: Used correctly, value marketing amounts to much more than just stashing prices distributing coupons. It means
giving the customer an improved product, with adds, features and enhancing the role of marketing itself: In value marketing, marketing becomes part of the system for delivering value t( the consumer. Instead of merely shaping image, such a program might offer enhance guarantees or longer warranties, ads that educate rather than hype, membership club: that build loyalty, frequent-buyer plans, improved communications with customer. through 800 numbers, or package design that makes the product easier to use or more environmentally friendly.
These and other value-marketing techniques can be expensive. They can tncar added production and marketing costs added to lower unit prices, Even so, the principle involved in value marketing value for money, an improved product, enhanced =Nice, and added features--are just %fiat U_S_ business needs to enhance its competitiveness in the global marketplace. That's why it will be all to the good if the commonsensical virtues of value marketing become part of the permanent strategy of U.S. business.
76. Consumers have waken up because of
A) the poor products they bought B) the high price they paid for what they bought
C) the difficult economic times D) a horrible dream
77. Many consumers are choosing the commodities
A) that are precious B) that are warranted
C) that can show their status D) that deliver the most for the money
78. In the 1980s, people would like to go after the products
A) that were most expensive B) that were up-to-date
C) that could show their status D) that were in fashion
79. Communications with customers malj be improved
A) through annual customers congress B) through ton free 800 numbers
C)through membership clubs D) through frequent education
80. A value marketing program may not include
A)daily visits to customers B)longer warranties
C)membership clubs D)environmentally friendly packages
Passage Three
Great emotional and intellectual resources are demanded in quarrels; stamina helps, as does a capacity for obsession. But no one is born a good quarreller; the craft must be learned.
There are two generally recognised apprenticeships. First, and universally preferred, is a long childhood spent in the company of fractious siblings. After several years of rainy afternoons, brothers and sisters develop a sure feel for the tactics of attrition and the niceties of strategy so necessary in first-rate quarrelling.
The only child, or the child of peaceful or repressed households, is likely to grow up failing to understand that quarrels, unlike arguments, arc not about an)1hing, least of all the pursuit of truth. The apparent subject of a quarrel is a mere pretext; the real business is the quarrel itself.
Essentially, adversaries in a quarrel are out to establish or rescue their dignity. I fence the elementary principle: anything may be said. The unschooled, probably no less quarrelsome by inclination than anyone else, may spend an hour with knocking heart, sifting the consequences of roiling this old acquaintance a lying fraud. Too late! With a cheerful wave the old acquaintance has left the room.
Those who miss their first apprenticeship may care to enrol in the second, the bad marriage. This can be perilous for the neophyte; the mutual intimacy of spouses makes them at once more vulnerable and more dangerous in attack. Once sex is involved, the stakes are higher all round. And there is an unspoken rule that those who love, or have loved, one another are granted a licence for unlimited beastliness such as is denied to mere sworn enemies. For all that, some of our most tenacious black belt quarrellers have come to it late in fife and mastered every throw, from the Crushing Silence to the Gloating Apology, in less than ten years of marriage.
A quarrel may last years. Among brooding types Kith time on their hands, like writers, half a lifetime is not uncommon. In its most refined form, a quarrel may consist of the participants not talking to each other. They will need to scheme laboriously to appear in public together to register their silence.
Brief, violent quarrels are also known as rows. In all cases the essential ingredient remains the same; the original cause must be forgotten as soon as possible. From here on, dignity, pride, self-esteem, honour ate the crucial issues, which is why quarrelling… like jealousy, is an all-consuming business, virtually a profession. For the quarreller's very self-hood is on the fine.
To lose an argument is a brief disappointment, much like losing a game of tennis; but to be crushed in a quarrel ... rather bite off your tongue and spread it at your opponent's feet.
81. Unschooled quarrellers are said to be at a disadvantage because
A) their insults fail to offend their opponent B) they reveal their nervousness to their opponent
C) they suffer from remorse for what they've said D) they are apprehensive about speaking their minds
82. According to the writer, quarrels between married couples may be_-__
- A) physically violent B) extremely IYitter
C) essentially trivial D) sincerely regretted
83.when quarrelling both children and married couples may, according to the writer
A) be particularly brutal B) use politeness as a weapon
C) employ skillful manoeuvres D) exaggerate their feelings
84. The difference between a quarrel and an argument is said to be that
A) the former involves individual egos B) the former concerns strong points of view
C) the latter has well-established miles D) the latter concerns trivial issues
85. In the passage as a whole, the writer treats quarrelling as if it were
A) a military campaign B) a social skill
C) a moral evil D) a natural gilt
Passage Four
`I just couldn't do it. I don't know what it is. It's not embarrassment. No that's not it. You see, you're putting your head in a noose; that's what it seems to me.' Derek am armed robber with a long record of bank jobs, was talking about hoisting (shop-lifting). `No I just couldn't do it. I mean just going in there.' He paused to try to fund a more exact way of fixing; his antipathy. `I tell you what. It's too blatant for my liking.'
It seemed a fanny way to put it. Pushing a couple of ties in your pocket at a shop was hardly the last word in extroversion, and even a bit on the discreet side when compared to all that firing of shotguns and vaulting over counters which made up the typical bank raid.
But my ideas of shop-lifting were still bound up with teenage memories of nicking packets of chewing gum from the local newsagents. A lot of guilt and not much loot_ After a few conversations with professional holsters, I realised that `blatant' was just about right.
Nobody took a couple of ties they took the whole rack. The fast member of the gang would walk in nice and purposefully. Their job was to set up the goods: perhaps put an elastic bawd round the ends of a few dozen silk scarves; move the valuable pieces of jewellery nearer the edge of the counter; slide the ties on the rack into a compact bunch. Then, wine somebody else diverts the assistant or provides some fort of masking, the third member lifts the lot
If the walk to the door is a little long, then there mm be someone else to take over for the last stretch. No one is in possession for more than a few seconds, and there's always a couple of spare bodies to obstruct any one who seems to be getting too near the carrier.
Store detectives who move forward with well-founded suspicions may still find themselves clutching empty air. Store detectives watch for three main give-sways: am- sort of loitering which looks different from the usual hanging around and dithering that characterises the real customer; any covert contact between individuals %N-ho %v shown no other sign of knowing each other, any over-friendliness towards sales staff which might be acting as a distraction. 'There's one other little angle', said one detective. 'l often pop round the back stairs; that's where you'll occasionally find one of them; trying to relax and get themselves in the right mood before starting the next job.'
86. The bank robber wouldn't consider shop-lifting because
A) it was beneath his dignity B) the penalties were too high
C) it wasn't challenging enough D) the risks were too great
87. The writer's experience led rum to think that most shop-lifters
A) were I their teens B) stole modest amounts
C) used violent methods D) stole for excitement
88. The; role of the first member of the gang is to
A) convince the staff he's a serious shopper B) remove die goods from the shelves
C) establish the easiest goods to steal D) smooth the. path for his accomplice .

武汉大学 2017年攻读博士学位研究生外语综合水平考试试题 （满分值100分） 科目名称：英语科目代码：1101 注意：所有的答题内容必须写在答案纸上，凡写在试题或草稿纸上的一律无效。 Part I Reading Comprehension (2’×20 = 40 points) Directions:In this part of the test, there will be 5 passages for you to read. Each passage is followed by 4 questions or unfinished statements, and each question or unfinished statement is followed by four choices marked A, B, C and D. You are to decide on the best choice by blackening the corresponding letter on the ANSWER SHEET. Passage One Mr Gordon is right that the second industrial revolution involved never-to-be-repeated changes. But that does not mean that driverless cars count for nothing. Messrs Erixon and Weigel are also right to worry about the West’s dismal recent record in producing new companies. But many old firms are not run by bureaucrats and have reinvented themselves many times over: General Electric must be on at least its ninth life. And the impact of giant new firms born in the past 20 years such as Uber, Google and Facebook should not be underestimated: they have all the Schumpeterian characteristics the authors admire. On the pessimists’ side the strongest argument relies not on closely watching corporate and investor behavior but rather on macro-level statistics on productivity. The figures from recent years are truly dismal. Karim Foda, of the Brookings Institution, calculates that labor productivity in the rich world is growing at its slowest rate since 1950. Total factor productivity (which tries to measure innovation) has grown at just 0.1% in advanced economies since 2004, well below its historical average. Optimists have two retorts. The first is that there must be something wrong with the figures. One possibility is that they fail to count the huge consumer surplus given away free of charge on the internet. But this is unconvincing. The official figures may well be understating the impact of the internet revolution, just as they downplayed the impact of electricity and cars in the past, but they are not understating it enough to explain the recent decline in productivity growth.
