Section C 26 A controversial new amendment by the Academy of Motion Picture Arts and Sciences is raising some red flags with documentary filmmakers. The Academy announced that only documentaries【 B1】 _b
17、y either the Los Angeles Times or the New York Times would be eligible for an Oscar nomination. Many filmmakers have【 B2】 _the change, arguing that the new rule unfairly favors films with high budgets and elite PR teams, which really【 B3】 _the writers for the screen stories. The Academy says that th
18、e change to the rules【 B4】 _counteract the growing trend of entries circumventing(回避 )the existing regulations. Currently, the rules state that to be considered in the documentary【 B5】 _, a film must show for at least one week in a theater, but some feel that studios can easily arrange a【 B6】_screen
19、ing run to ensure their films inclusion. Martin Scorseses George Harrison documentary was intended primarily for HBOs cable channel, but enjoyed a week-long screening to【 B7】 _for the Oscar. The adjustments are believed to curb such a nomination, but others see more problems than solutions. “The cha
20、nges do not【 B8】 _the key problem, which is 99% of the documentaries being made are not released in theaters. So tightening up the rules for theatrical release just【 B9】 _the issue all the more,“ two-time Oscar nominee Lawrence Hott told the Los Angeles Times. “I would prefer to see the academy【 B10

In recent years, computer experts, particularly those【 C1】 _in artificial intellig
22、ence, have felt the fascination. Programming other board games has been a relative snap. Even chess has【 C2】 _ to the power of the processor. Five years ago, a chess-playing computer called Deep Blue not only beat but thoroughly【 C3】 _Garry Kasparov, the world champion at that time. That is because
23、chess, while highly complex, can be reduced to a matter of brute force computation. Go is different. Deceptively easy to learn, either for a computer or a human, it is a game of such depth and【 C4】 _that it can take years for a person to become a strong player. To date, no computer has been able to
24、achieve a skill level beyond that of the casual player. The game is played on a board divided into a grid of 19【 C5】 _and 19 vertical lines. Black and white pieces called stones are placed one at a time on the grids intersections. The object is to acquire and defend【 C6】 _by surrounding it with ston
25、es. Programmers working on Go see it as more accurate than chess in【 C7】_the ways the human mind works. The challenge of programming a computer to mimic that process goes to the core of artificial intelligence, which involves the study of learning and decision-making, strategic thinking, knowledge r
26、epresentation, pattern recognition and perhaps most intriguingly, intuition. In the【 C8】 _of a chess game, a player has an average of 25 to 35 moves available. In Go, on the other hand, a player can choose from an average of 240 moves. A Go-playing computer would need about 30 000 years to look as f
27、ar ahead as Deep Blue can with chess in three seconds. But the【 C9】 _go deeper than processing power. Not only do Go programs have trouble evaluating positions quickly; they have trouble making it correctly.【 C10】 _, the allure(吸引力 )of computer Go increases as the difficulties it poses encourages pr

29、 43 【 C7】 44 【 C8】 45 【 C9】 46 【 C10】 Section B 46 Can the PC Industry Resurrect Itself? 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 playi
30、ng in peoples lives is changing, and the growing demand for tablets and smartphones has 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 poi
31、nt that people are either keeping their current PCs longer or if they buy a new PC or laptop, 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 chal
32、lenge from tablets and smartphones? It turns out that people have found they can do as 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 manage
33、ment, extensive photo editing, making complex home movies, doing their taxes and other 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
34、PCs in the $ 799- $ 999 range-those which have higher-end processors, extended graphics 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
35、want to pay is $ 599, with most preferring price points of $399-$449. This is why Ultrabook 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 bu
36、ying trends for PCs, they are not about to give up without a fight. Almost all are trying 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
37、they now understand that the market for laptops and PCs in the $ 699- $ 999 price point 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 m
38、uch smaller market than the consumer sector. Even though volume in these is smaller than 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 co
39、st clamshell-based(翻盖式的 )laptops and tablets with very aggressive pricing, and hope to 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 indica
40、tion of Intel and its PC partners strategy last week when he spoke on a conference call 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 m
41、ore affordable laptops and Windows 8 tablets on the horizon. We are hearing that all 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 whil
42、e some will look like normal laptops or convertibles, to get this distinction, and to 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 he
43、lp drive PC sales higher due to consumers demand to upgrade their laptops to touch-based 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
44、 interfaces on their smartphones and tablets and it is logical that they would want a 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
45、 to smartphones and tablets, they are convinced that even if they use a PC for 20% of 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 cons
46、umers want really low priced touch-based laptops that are good enough to handle anything 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
47、most of these will be at least $ 599 and higher. I)So what does this mean for consumers 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 wi
48、th poor battery life; their days are numbered. The industry will still offer some of 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 i
49、f a person needs to buy a new PC there will be a touch-based Windows 8 laptop they can 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 come in many flavors. Some will be traditional clamshells, sporting scree
