　　下面是小編整理的，希望對大家有幫助。

　　Passage One

　　Questions 56 to 60 are based on the following passage.

　　The "paperless office" has earned a proud place on lists of technological promises that did notcome to pass. Surely, though, the more modest goal of he carbon-paperless office is within thereach of mankind? Carbon paper allows two copies of a document to be made at once. Nowadays,a couple of keystrokes can do the same thing with a lot less fuss.

　　Yet carbon paper persists. Forms still need to be filled out in a way that produces copies. Thisshould not come as a surprise. Innovation tends to create new niches*** 合適的職業***, rather than refillthose that already exist. So technologies may become marginal, but they rarely go extinct. Andtoday the little niches in which old technologies take refuge are ever more viable and accessible,thanks to the Internet and the fact that production no longer needs to be so mass; making smallnumbers of obscure items is growing easier.

　　On top of that, a widespread Technology of nostalgia***技術懷舊 *** seeks to preserve all theways people have ever done anything, simply because they are kind of neat. As a resulttechnologies from all the way back to the stone age persist and even flourish in the modern world.According to What Technology Wants, a book by Kevin Kelly, one of the founders of Wiredmagazine, America's flintknappers ***燧石*** produce over a million new arrow and spear heads everyyear. One of the things technology wants, it seems, is to survive.

　　Carbon paper, to the extent that it may have a desire for self-preservation, may also takecomfort in the fact that, for all that this is a digital age, many similar products are hanging on, andeven making comebacks. Indeed, digital technologies may prove to be more transient than theirpredecessors. They are based on the idea that the medium on which a file's constituent 0s and 1sare stored doesn't matter, and on Alan Turing's insight that any computer can mimic any other,given memory enough and time. This suggests that new digital technologies should be able to wipeout their predecessors completely. And early digital technologies do seem to be vanishing. The musiccassette is enjoying a little renaissance, its very faithlessness apparently part of its charm; butdigital audio tape seems doomed.

　　So revolutionary digital technologies may yet discard older ones to the dustbin. Perhaps thiswill be the case with a remarkable breakthrough in molecular***分子的*** technology that could, inprinciple, store all the data ever recorded in a device that could fit in the back of a van. In thisinstance, it would not be a matter of the new extinguishing the old. Though it may never have beenused for MP3s and PDFs before, DNA has been storing data for over three billion years. And it showsno sign of going extinct.

　　56. Which of the following is TRUE about the carbon paper?

　　A*** It is the key to paperless office.

　　B*** It will be replaced by the computer soon.

　　C*** It is more troublesome than the computer.

　　D*** It can hardly survive in the digital age.

　　57. According to the passage, "viable" *** Line 4, Para. 2*** means __

　　A*** secure

　　B*** dynamic

　　C*** feasible

　　D*** flexible

　　58. Why does the author mention the example of What Technology Wants by Kevin Kelly?

　　A*** To point out that old Technology of nostalgia will flourish in the modern world.

　　B*** To illustrate the importance of flintknappers.

　　C*** To show that flintknapping is one of the stone age technologies.

　　D*** To prove that old technologies seemingly never die.

　　59. What can be inferred about digital technologies?

　　A*** Digital audio tape will be vanished because of its accuracy.

　　B*** Digital technologies have been proved to outlive the old technologies.

　　C*** Early digital technologies will never go extinct.

　　D*** The future of digital technologies will be used for DNA research.

　　60. The passage mainly concerned with

　　A*** the difficulty of the realization of paperless office

　　B*** the fact that newest technologies may die out while the oldest survive

　　C*** the reason why old technologies will never be on the edge of extinction

　　D*** the importance of keeping improving technologies all the time

　　Passage Two

　　Questions 61 to 65 are based on the following passage.

　　Recent reports suggest that tea can cause brittle bones-but you'll probably be safe if you drinkless than a gallon a day.

　　Do you fancy a cup of tea? We drink, on average, three mugs a day. But you might want to tryanother strong alcohol after hearing the case of a 47-year-old woman, published in the NewEngland Journal of Medicine ***NEJM***, who developed brittle bones and lost all of her teeth afterdrinking too much tea.

　　Tea may not be so great for prostates ***前列腺*** either. Last year, research from the Universityof　Glasgow found that men who drank more than seven or more cups of tea a day had a 50%higher risk of　prostate cancer. And in 2009 a paper in the British Medical Journal showed thatdrinking very hot tea***70oC or more*** increased the likelihood of esophageal ***食管的*** cancer.

　　Still gasping for that cup of tea? There is some evidence that tea can be good for you too,with　antioxidant properties, so maybe you're not actually drinking enough of the stuff.

　　The poor woman in the NEJM study is not alone. There are a few other cases of people whohave　damaged their bones through too much tea. But she ***like those in other studies*** was drinkingexcessive　amounts: 100 - 150 tea bags a day to make 12 cups of tea. A litre of tea can containup to 9mg of fluoride***氟化物***, which in excess can cause skeletal fluorosis *** 氟中毒***, reducing bonequality and causing pain and stiffening of the ligaments ***韌帶***. Other studies show you generallyneed to drink a gallon a day for three decades to develop this condition.

　　You also shouldn't worry about the Glasgow study as it wasn't designed to show that drinkingtea actually caused prostate cancer. All it proved was an association and people were only askedhow much tea they drank at the start of the study, which went on for about 28 years.

　　The National Cancer Institute in the U.S. concludes that the evidence isn't good enough to saytea either harms or helps our health. However it does seem sensible in the light of the BMJ study towait for your tea to cool down for a few minutes.

　　Black tea, which makes up 75% of the world's consumption, may have healthy properties fromits plant chemicals called poly phenols***多酚***, which are antioxidants. Green tea contains more polyphenols but isn't so nice to dunk digestives into.

　　A review of the evidence in the European Journal of Clinical Nutrition, sponsored by the TeaCouncil--which, the authors say, had no part in the study--found the research showed more thanthree cups of black tea a day reduced heart disease. It found no evidence of harm "in amountstypically consumed". So as long as you drink less than a gallon of tea a day you should beabsolutely fine.

　　61. What can be inferred about tea from Paragraph 3?

　　A*** Very hot tea may cause prostate cancer.

　　B*** There may be a link between very hot tea and esophageal cancer.

　　C*** Over-drinking tea is the cause of prostate cancer.

　　D*** Drinking too much tea may worsen esophageal cancer.

　　62. Excessive intake of fluoride may

　　A*** increase the likelihood of heart attack

　　B*** cause the bone fracture

　　C*** cause fluorosis in the blood

　　D*** weaken the bone quality and hurt the ligaments

　　63. Which of the following instructions is encouraged to practice?

　　A*** Drinking less tea in the future.
