Section A 26 Passwords are a pain in the ass. Theyre either easy to【 C1】 _ or hard to remember, and when breaches

15、 (破坏 )【 C2】 _ you have to come up with a whole new one. So people are trying to do away with passwords altogether, and so far fingerprint scanners are doing the job nicely. Still, fingerprints alone are not【 C3】 _ . Online security has become【 C4】_ important, forcing service providers to come up wit

Companies are turning to other parts of our bodies to find biometric (生物计量的 )【 C6】 _ that are up to the task, and our faces and eyes are at the top of the list. Although facial and eye-based recognition appear gimm

17、icky for now, they may soon become as prevalent and popular as fingerprint scanners. That pairing could root out passwords and clunky text-message two-factor【 C7】 _ altogether, making it a completely biometric process. The popularity, prevalence and convenience of fingerprint scanning means it is he

Choudhury sees the newer method as a complement to fingerprints, providing a more convenient second-factor authentication as opposed to entering a text code sent to your phone.

21、】 33 【 C7】 34 【 C8】 35 【 C9】 36 【 C10】 Section B 36 Corporate Ambitions: Amazon, the Worlds Most Remarkable Firm, Is Just Getting Started A) Amazon is an extraordinary company. The former bookseller accounts for more than half of every new dollar spent online in America. It is the worlds leading pro

22、vider of cloud computing. This year Amazon will probably spend twice as much on television as HBO, a cable channel. Its own-brand physical products include batteries, almonds, suits and speakers linked to a virtual voice-activated assistant that can control, among other things, your lamps and sprink

23、ler. B) Yet Amazons shareholders are working on the premise that it is just getting started. Since the beginning of 2015 its share price has jumped by 173%, seven times quicker than in the two previous years (and 12 times faster than the S Walmart already has revenues nudging $ 500bn and is beefing

24、up online. If anything happened to Jeff Bezos, Amazons founder and boss, the gap would be exceptionally hard to fill. But the striking thing about the company is how much of a chance it has of achieving such unprecedented goals. E) This is largely due to the firms unusual approach to two dimensions

25、of corporate life. The first of these is time. In an era when executives routinely whinge about (发牢骚 ) pressure to produce short-term results, Amazon is resolutely focused on the distant horizon. Mr. Bezos emphasises continual investment to propel (推动 ) its two principal businesses, e-commerce and A

26、mazon Web Services (AWS), its cloud-computing arm. F) In e-commerce, the more shoppers Amazon lures, the more retailers and manufacturers want to sell their goods on Amazon. That gives Amazon more cash for new servicessuch as two-hour shipping and streaming video and musicwhich entice more shoppers.

27、 Similarly, the more customers use AWS, the more Amazon can invest in new services, which attract more customers. A third virtuous circle is starting to whirl (迅速旋转 ) around Alexa, the firms voice-activated assistant: as developers build services for Alexa, it becomes more useful to consumers, givin

28、g developers reason to create yet more services. G) So long as shareholders retain their faith in this model, Amazons heady valuation resembles a self-fulfilling prophecy. The company will be able to keep spending, and its spending will keep making it more powerful. Their faith is sustained by Amazo

29、ns record. It has had its failuresits attempt to make a smartphone was a debacle. But the business is starting to crank out (快速大量地制造 ) cash. Last year cashflow (before investment) was $ 16bn, more than quadruple the level five years ago. H) If Amazons approach to time-frames is unusual, so too is th

30、e sheer breadth of its activities. The companys list of current and possible competitors, as described in its annual filings, includes logistics firms, search engines, social networks, food manufacturers and producers of “physical, digital and interactive media of all types“. A wingspan this large i

31、s more reminiscent of a conglomerate (大型联合企业 ) than a retailer, which makes Amazons share price seem even more bloated: stockmarkets typically apply a “ conglomerate discount“ to reflect their inefficiencies. I) Many of these services support Amazons own expansion and that of other companies. The ob

32、vious example is AWS, which powers Amazons operations as well as those of other firms. But Amazon also rents warehouse space to other sellers. It is building a $ 1. 5bn air-freight hub (中心 ) in Kentucky. It is testing technology in stores to let consumers skip the cash register altogether, and exper

33、imenting with drone deliveries to the home. Such tools could presumably serve other customers, too. Some think that Amazon could become a new kind of utility: one that provides the infrastructure of commerce, from computing power to payments to logistics. J) And here lies the real problem with the e

34、xpectations surrounding Amazon. If it gets anywhere close to fulfilling them, it will attract the attention of regulators. For now, Amazon is unlikely to trigger antitrust (反垄断的 ) action. It is not yet the biggest retailer in America, its most mature market. Americas antitrust enforcers look mainly

35、at a firms effect on consumers and pricing. Seen through this lens, Amazon appears pristine (处于原始状态的 ). Consumers applaud it; it is the most well-regarded company in America, according to a Harris poll. (AWS is a boon to startups, too.) K) But as it grows, so will concerns about its power. Even on s

36、tandard antitrust grounds, that may pose a problem: if it makes as much money as investors hope, a rough calculation suggests its earnings could be worth the equivalent of 25% of the combined profits of listed Western retail and media firms. But regulators are also changing the way they think about

37、technology. In Europe, Google stands accused of using its clout as a search engine to extend its power to adjacent businesses. The comparative immunity from legal liability of digital platformsfor the posting of inflammatory content on Facebook, say, or the vetting of drivers on Uberis being chipped

38、 away. L) Amazons business model will also encourage regulators to think differently. Investors value Amazons growth over profits; that makes predatory pricing more tempting. In future, firms could increasingly depend on tools provided by their biggest rival. If Amazon does become a utility for comm

39、erce, the calls will grow for it to be regulated as one. Shareholders are right to believe in Amazons potential. But success will bring it into conflict with an even stronger beast: government. 37 Amazon has formed sound circles that push its e-commerce, AWS and Alexa voice service forward. 38 There

40、 is less chance of American government filing an antitrust lawsuit against Amazon because of its scale as a retailer and customers positive comments. 39 The two potential perils faced by Amazon come from its competitors and its leader Jeff Bezos respectively. 40 Amazon used to sell books online, but

41、 now the company has expanded its business scope into providing cloud computing and manufacturing its own physical products. 41 Its believed that Amazon will offer infrastructure of commerce with its AWS, rental warehouse space, logistics center in Kentucky, checkout-free shopping technology and dro

42、ne delivery. 42 The development of Amazon and the changing attitude of regulators towards technology will possibly bring Amazon antitrust trouble in the future. 43 Amazons executives havent experienced the same pressure as their counterparts in other companies due to Amazons forward-looking strategy

43、 about continuing investing in e-commerce and AWS. 44 Amazon remains so high in market value for so long but so small in profit that no other company in history can match with it. 45 Despite Amazons setback in making smartphones, this business is now turning a profit. 46 The investors double expecta

44、tions for Amazon suggest that it is likely to become the most profitable company in America. Section C 46 In todays world, online social media has become more powerful and the most destructive thing over worldwide. Although with time all generations have come to embrace the changes social network ha

45、s brought about, teenagers and young adults are the most fanatic users of these sites. According to various research studies in the field of online social networks, it has been revealed that these sites are impacting the lives of the youth greatly. When using these sites such as Twitter, Facebook or

46、 Myspace, there are both positive and negative effects on the youth. Firstly, social media helps the youth and any other user updated with what is happening around the world, and helps the teenagers stay connected and interact with each other even if they are many miles apart. This strengthens their

47、 relationship. Even if they finished school and moved to different locations, they stay connected and update one another. In addition, social media sites have provided a platform whereby the youth can create groups and pages based on their common discipline and end up building connections and opport

48、unities for their respective careers by updating various topics to discuss. Youth who have been interviewed say that social media has become their lifestyle and it makes their lives easier and more efficient. While on the one hand social network sites seem to bring people together and stay connected

49、, on the other hand it causes many physical and mental health problems such as eyes infection, back problems, etc. Other negative effects of social networking various people suggested included encouraging poor spelling and grammar, exposing underage to online predators (捕食者 ), allowing spread of misinformation that is seen as fact, decreasing productivity as those who are supposed to be working spend time in the sites to chat, providing a perfect platform for cyberbullying and providing detai
