7、Disabling Fake Accounts A)Alicia Istanbul woke up one recent Wednesday to find herself locked out of the Facebook account she opened in 2007, one Facebook suddenly deemed fake. The stay-at-home mom was cut off not only from her 330 friends, including many she had no other way of contacting, but also
8、 from the pages she had set up for the jewelry design business she runs from her Atlanta-area home. B)Although Istanbul understands why Facebook insists on having real people behind real names for every account, she wonders why the online hangout didnt simply ask before acting. “They should at least
9、 give you a warning, or at least give you the benefit of the doubt,“ she said. “I was on it all day. I had built my entire social network around it. Thats what Facebook wants you to do.“ Facebooks effort to purge its site of fake accounts, in the process knocking out some real people with unusual na
10、mes, marks yet another challenge for the 5-year-old social network. C)As Facebook becomes a bigger part of the lives of its more than 200 million users, the Palo Alto, Calif. -based company is finding that the huge diversity and the vast size of its audience are making it increasingly difficult to e
11、nforce rules it set when its membership was smaller and more homogenous(相似的 ). D)Having grown from a closed network available only to college students to a global social hub used by multiple generations, Facebook has worked over the years to shape its guidelines and features to fit its changing audi
12、ence. But requiring people to sign up under their real name is part of what makes Facebook Facebook. E)To make sure people cant set up accounts with fake names, the site has a long, constantly updated “blacklist“ of names that people cant use. Those could either be ones that sound fake, like Batman,
13、 or names tied to current events, like Susan Boyle. While there are dozens of Susan Boyles on Facebook already, people who tried to sign up with that name after the 47-year-old woman became an unlikely singing sensation(引起轰动的人物 )had more difficulty doing so. F)Facebook spokesman Barry Schnitt acknow
14、ledged that Facebook does make mistakes on occasion, and he apologized for “any inconvenience“. But he said situations like Istanbuls are very rare, and most accounts that are disabled for being fake really are. “The vast, vast, vast majority of people we disabled we never hear from again,“ he said.
15、 Because the exceptions are so rare, he said, prior notification is “not something we are doing right now.“ G)Facebook is available in more than 40 languages and growing and its user base is larger than Brazils population. But financially it is still a start-up. Although the Internet research firm e
16、Marketer estimates that Facebook generated about $ 210 million in US advertising revenue last year, that is well below the $585 million estimated for the News Corp.-owned rival, MySpace. Facebook is still looking for ways to become self-sustaining and reduce its reliance on outside investors. In 200
17、7, Microsoft bought a 1.6% stake in the company for $240 million, though Facebook later concluded it wasnt worth anywhere close to the $ 15 billion market value implied in that investment. H)Because Facebook has only about 850 employees worldwide, getting complaints answered can take a long time. Is
18、tanbul, whose father is from the city of Istanbul in Turkey, said it took three weeks to get her account reinstated(恢复 ). I)Without being able to log in for that time, she said she felt “completely cut off“ from her contacts. Frustrated, she wrote e-mails, then mailed letters to 12 Facebook executiv
19、es. To keep in touch with her friends and monitor her business pages, Istanbul said she sort of “hijacked“ her husbands account. “I think they just assume you cant have an interesting name,“ she said of Facebook. “I kept my maiden name because its such an interesting name, I didnt want to give it up
20、. And now I am having to defend my name. “ J)“If you deal with this kind of thing all the time, and on top of that Facebook wants you to prove your identity, . its adding insult to injury,“ said Nancy Kelsey, a graduate student at the University of Nebraska in Lincoln, who started the Facebook group
21、. She said Facebook should remedy the problem so that it “wouldnt be so offensive“ each time a real name is deemed fake. “Native American surnames mean something,“ she said. “They are points of pride, points of identity. Its not someone trying to make up a fake name.“ K)Istanbuls sister, Lisa Istanb
22、ul Krikorian, also got locked out of her Facebook account, which she opened a year and a half ago. So she opened another one that omits her maiden name. Their mother and their cousin, who both joined the social network more recently, were not even allowed to sign up under their real names. “They had
23、 to misspell their last names,“ Alicia Istanbul said, so that Facebooks system of weeding out fake accounts wouldnt recognize them. Her mom added an extra “n“ to spell “Istannbul“, and her cousin added an “e“ to become “Istanbule“. L)But that makes it difficult to reconnect with old classmates and l
24、ong-lost friends, something Facebook prides itself in helping facilitate. “No one is going to find you if your last name is spelled wrong,“ Istanbul said. Unlike many other social networks, Facebook wants a real name behind each persons account. Bands, brands and businesses are supposed to use fan p
25、ages and groups; regular accounts are for real people. M)Facebook says its “real name culture“ is one of the sites founding principles. It creates “accountability(责任 )and, ultimately, creates a safer and more trusted environment for all of our users,“ Schnitt said. “We require people to be who they
26、are. “ N)Once the site disables an account it deems fake, its holder has to contact Facebook to prove it is real. In some cases, the company may require that the person fax a copy of a government-issued ID, which Facebook says it destroys as soon as the account is verified. O)Yet an informal search
27、on Facebook shows that efforts to weed out fake names may be a difficult task. A recent search for “stupid“, for example, turned up more than 27 people matches, most looking dubious(可疑的 )at best. Although many of the fake accounts are created as sophomoric(幼稚的 )humor or as a vehicle for malicious ac
28、tivity, others are to protect users from having their postings create problems when they later look for jobs. Facebook has extensive privacy settings, but they are complicated and many people dont know how to properly use them. P)Steve Jones, professor of communications at the University of Illinois
29、 at Chicago, said having real people behind personal accounts helps Facebook maintain credibility. “If they let fake names and accounts proliferate(扩散 )people are going to take it less seriously,“ he said. Still, he believes that Facebook should notify the holders of purportedly(据称 )fake accounts. “
30、The first step in any sort of takedown action is to notify,“ he said. “Whats the rush? Why not give somebody 24, 48 hours?“ 11 In order to prevent users from using fake names, Facebook lists a series of names that are not allowed to use. 12 According to Nancy Kelsey, Facebook should make some change
31、s to avoid misunderstanding. 13 Facebook adopts the founding principle of “real name culture“ for the purpose of providing its users with a safer and more trusted environment. 14 The Palo Alto finds it difficult to enforce rules, for the number of its users increases and they have different needs. 1
32、5 Professor Steve Jones said the “real name culture“ could help Facebook maintain credibility. 16 Alicia Istanbul runs the jewelry design business at home on the Internet. 17 Some postings on Facebook may bring trouble to its users when they later look for jobs. 18 According to the Internet research
33、 firm eMarketer. Facebook was financially inferior to its rival last year. 19 To avoid their accounts being disabled, Alicia Istanbuls family misspell their names. 20 Barry Schnitt said most disabled accounts are really fake names. Section C 20 Someday a stranger will read your e-mail without your p
34、ermission or scan the websites youve visited. Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out your shopping preferences or calling habits. In fact, its likely some of these things have already happened to you. Who would watch you without you
35、r permission? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal. Whoever it is, they will see you in a way you never intended to be seen the 21st century equivalent of being caught naked. Psychologists tell us boundaries are healthy, that its important to reveal yo
36、urself to friends, family and lovers in stages, at appropriate times. But few boundaries remain. The digital bread crumbs(碎屑 )you leave everywhere make it easy for strangers to reconstruct who you are, where you are and what you like. In some cases, a simple Google search can reveal what you think.
37、Like it or not, increasingly we live in a world where you simply cannot keep a secret. The key question is: Does that matter? For many Americans, the answer apparently is “no“. When opinion polls ask Americans about privacy, most say they are concerned about losing it. A survey found an overwhelming
38、 pessimism about privacy, with 60 percent of respondents saying they feel their privacy is “slipping away, and that bothers me.“ But people say one thing and do another. Only a tiny fraction of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at
39、tollbooths(收费站 )to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy economist Alessandro Acquisti has run a series of tests that reveal people will surrender personal information like Social Security numbers just to get their ha
40、nds on a pitiful 50-cents-off coupon(优惠券 ). But privacy does matter at least sometimes. Its like health; when you have it, you dont notice it. Only when its gone do you wish youd done more to protect it. 21 What does the author mean by saying “the 21st century equivalent of being caught naked“(Para.
41、 2)? （ A） Peoples personal information is easily accessed without their knowledge. （ B） In the 21st century people try every means to look into others secrets. （ C） People tend to be more frank with each other in the information age. （ D） Criminals are easily caught on the spot with advanced technol

43、oes the author say “we live in a world where you simply cannot keep a secret“(Line 5, Para. 3)? （ A） Modern society has finally evolved into an open society. （ B） People leave traces around when using modern technology. （ C） There are always people who are curious about others affairs. （ D） Many sea
44、rch engines profit by revealing peoples identities. 24 What do most Americans do with regard to privacy protection? （ A） They change behaviors that might disclose their identity. （ B） They use various loyalty cards for business transactions. （ C） They rely more and more on electronic devices. （ D） T
45、hey talk a lot but hardly do anything about it. 25 According to the passage, privacy is like health in that_. （ A） people will make every effort to keep it （ B） its importance is rarely understood （ C） it is something that can easily be lost （ D） people dont cherish it until they lose it 25 By almos
46、t any measure, there is a boom in Internet-based instruction. In just a few years, 34 percent of American universities have begun offering some form of distance learning(DL). and among the larger schools, its closer to 90 percent. If you doubt the popularity of the trend, you probably havent heard o
47、f the University of Phoenix. It grants degrees entirely on the basis of online instruction. It enrolls 90 000 students, a statistic used to support its claim to be the largest private university in the country. While the kinds of instruction offered in these programs will differ, DL usually signifie
48、s a course in which the instructors post syllabi(课程大纲 ), reading assignments, and schedules on Websites, and students send in their assignments by e-mail. Generally speaking, face-to-face communication with an instructor is minimized or eliminated altogether. The attraction for students might at fir
49、st seem obvious. Primarily, theres the convenience promised by courses on the Net: you can do the work, as they say, in your pajamas(睡衣 ). But figures indicate that the reduced effort results in a reduced commitment to the course. While drop-out rates for all freshmen at American universities is around 20 percent, the rate for online students is 35 percent. Students themselves seem to understand the weaknesses inherent in the setup. In a survey conducted for eCornell, the DL division
