16、ity. Section C 26 They may appear to be marvels of modern science. But the ideas that led to the wonders of satellite【 B1】 _, organ transplant and cosmetic surgery are not quite as recent as some might think, for 350 years ago, Robert Boyle, a natural【 B2】 _and founder of modern chemistry, put pen t
17、o paper to【 B3】 _a wish-list of what he hoped science would one day achieve. His wish list covers real scientific developments that【 B4】 _ the entirety of the next four centuries from the arrival of the coffee house, to the dawn of air travel right through to the developments in【 B5】 _agriculture. I
18、t is thought that the list was penned by an assistant with Boyle, a leading intellectual figure【 B6】 _, dictating his hopes for the future. The result is a list of 24 aspirations, which would have been widely discussed with his scientific【 B7】 _but would doubtless have seemed outlandish(奇异的 )dreams
19、to the 17th century man on the street. Boyles first “wish“ was the “Prolongation(延伸 )of Life.“ Since the【 B8】 _life expectancy at the start of the 17th century was just 40, his first wish was certainly achieved. And it remains a hot topic for scientists today. Next he pondered on the “Recovery of Yo
20、uth, or at least some of the Marks of it, as new Teeth, new Hair coloured as in youth. “ Did he【 B9】 _that four centuries later the wonders of modern dentistry would be granting new teeth to order and that a youthful looking was just a bottle away? Other wishes cover key developments in engineering
21、and chemistry,【 B10】 _medicine. Some such as the transformation of species in minerals, animals and vegetables remain at sciences cutting edge today. 27 【 B1】 28 【 B2】 29 【 B3】 30 【 B4】 31 【 B5】 32 【 B6】 33 【 B7】 34 【 B8】 35 【 B9】 36 【 B10】 Section A 36 Campus Crime We often think of agriculture as
22、planting seeds and harvesting crops. But many crops do not come from seeds. Many kinds of trees and plants are grown from【 C1】 _cut from existing trees and plants. This is called grafting(嫁接 ). Farmers cut branches or young growths, called【 C2】 _, from one plant and place them on a related kind of p
23、lant. The branch or bud that is grafted is called a scion(接穗 ). The plant that【 C3】 _the graft is called the root stock. Over time, the【 C4】 _from the two plants grow together. The grafted plant begins to【 C5】 _the leaves and fruit of the scion, not the root stock. A graft can be cut in several ways
24、. A cleft graft(割接，劈接 ), for example, requires a scion with several buds on it. The bottom of the scion is cut in the【 C6】 _of the letter V. A place is cut in the root stock to accept the scion. The scion is then【 C7】 _placed into the cut on the root stock. Growth medium is put on the【 C8】 _to keep
25、it wet and help the growth. Grafting can join scions with【 C9】 _ qualities to root stock that is strong and resists disease and insects. Some common fruit trees such as sweet cherries have to be grafted. In an age of high-technology agriculture, grafting is a low-technology method that remains【 C10】

27、lf? A)Internet Data Centers(IDC)recent report stated that PC shipments declined 13.9% last quarter, the worst since IDC has been tracking PCs. It says a lot about the state of the PC industry. The role PCs are playing in peoples lives is changing, and the growing demand for tablets and smartphones h
28、as taken its toll on the PC market. Last week my son Ben, in his column for TIME Tech entitled The iPad-Sized Nail in the PCs Coffin laid much of the blame on the iPad for deflating PC sales. Ben also made the point that people are either keeping their current PCs longer or if they buy a new PC or l
29、aptop, they buy cheaper models because they are “good enough“ to use for any computing needs that cant be accomplished on a tablet. B)But is the PC really dead? And if not, how will PC vendors respond to this challenge from tablets and smartphones? It turns out that people have found they can do as
30、much as 80% on a tablet that they used to do on a PC. However, they have also found out that tablets by themselves cannot meet all of their digital computing needs, especially for handling things like media management, extensive photo editing, making complex home movies, doing their taxes and other
31、similar tasks. This suggests that if they only need a PC 20% of the time, the need to buy an expensive PC does not make sense for most people. C)For the past 10 years, a good part of PC sales were for laptops and PCs in the $ 799- $ 999 rangethose which have higher-end processors, extended graphics
32、capabilities and more on-board memory and hard drive space than laptops and PCs priced well below $ 699. We are hearing from consumers that if they only use a PC or laptop 20% of the time, the highest price they want to pay is $599, with most preferring price points of $ 399- $ 449. This is why Ultr
33、abook sales have been very disappointing for the PC vendors who hoped that their touch-based Ultrabooks priced from $ 799- $ 1 099 would be big sellers. D)While PC vendors are quite aware of the shift in consumer buying trends for PCs, they are not about to give up without a fight. Almost all are tr
34、ying to do tablets of their own and some, like Lenovo, are even doing smartphones and have actually done quite well in the Asian and Chinese smartphone markets. I think that reality has sunk in for the vendors, and they now understand that the market for laptops and PCs in the $ 699- $ 999 price poi
35、nt is being marginalized. E)The good news is that there is still healthy demand for upscale laptops and PCs in the $ 1 099 $ 1 499 price range. But demand for these is mostly in the IT, business and SMB market, a much smaller market than the consumer sector. Even though volume in these is smaller th
36、an those that sell into the consumer market, the margins are good, so these vendors are happy with what they call the premium market for PCs. However, they are also shifting much of their efforts to creating low cost clamshell-based(翻盖式物品 )laptops and tablets with very aggressive pricing, and hope t
37、o use these to lure millions of PC users who have tablets but still need a PC for some tasks to upgrade their current PCs to more up-to-date touch-based models. F)In fact, Intel CEO Paul Otellini gave us some indication of Intel and its PC partners strategy last week when he spoke on a conference ca
38、ll regarding Intels recent earnings announcement. He said, “If you look at touch-enabled non-core Intel-based notebooks that are ultrathin. those prices are going to be down to as low as $ 200,“ hinting perhaps at more affordable laptops and Windows 8 tablets on the horizon. We are hearing that all
39、of the PC vendors are working on what they call “ultramobiles,“ which are very low cost touch-based clamshells and convertible tablets for this holiday season. G)Key to understanding ultramobile designs is that while some will look like normal laptops or convertibles, to get this distinction, and to
40、 qualify for Microsofts low cost license to use Windows Blue, they have to be systems that only use Intels Atom chip or a similar competitive one from AMD. Ultimately, the vendors believe these ultramobiles could help drive PC sales higher due to consumers demand to upgrade their laptops to touch-ba
41、sed systems. By the way, clamshell-based Chromebooks are in this ultramobile category too, even though they use Googles Chrome web browser as the operating system. H)Consumers have gotten very comfortable with touch interfaces on their smartphones and tablets and it is logical that they would want a
42、 similar interface on any new PC or laptop they upgrade to in the future. Indeed, this is what Intel, Microsoft and their PC partners are banking on. While they accept that users primary computing tasks are shifting to smartphones and tablets, they are convinced that even if they use a PC for 20% of
43、 their digital computing needs, the next one they buy will be touch-based. While Intel, Microsoft and the vendors would prefer selling people touchscreen ultrabooks at higher prices, they are now realizing that consumers want really low priced touch-based laptops that are good enough to handle anyth
44、ing they cant get done on a tablet or smartphone. This is why ultramobile devices are being created. It does not mean that consumers will not have higher-end Intel touch-based Ultrabooks to choose from as well, but most of these will be at least $ 599 and higher. I)So what does this mean for consume
45、rs this fall? Although consumers have been able to buy what we call value notebooks well under $ 599 for some time, most of these use older processors, non-touch screens, and traditional hard drives and are bulky with poor battery life; their days are numbered. The industry will still offer some of
46、these types of value notebooks for at least another year. But the push will be very strong from Intel, AMD and Microsoft to drive everyone to touch-based laptops in various price ranges, making it more likely that if a person needs to buy a new PC there will be a touch-based Windows 8 laptop they ca
47、n afford. I suspect that within 12-18 months, non-touch-based laptops of any flavor will be hard to find. J)What consumers can expect this fall are ultramobiles using either Intels Atom processor or the Temash version from AMD, with touchscreens, SSD drives, and thin and light designs. They will com
48、e in many flavors. Some will be traditional clamshells, sporting screens from 10. 1 to 11. 6 inches. Some will be what we call convertibles, which are clamshells that look like a traditional laptops but the screens pop off to become tablets. Some models will be like Lenovos Yoga, a laptop in which t
49、he screen folds back to make it a tablet, except the screen is not detachable. And some will be exactly like Microsofts current Surface Pro or Surface RT models. More importantly, they will all be priced under $ 599 with some coming in as low as $ 399- $ 499 by the holidays. K)Vendors will also offer Ultrabooks that use Intels dual-core processors, flash memory, touchscreens and also be thin and light but they will all be at least $ 59
