问题     If there is one thing that could halt the ascent of social networks, it is the thorny question of privacy. This is【C1】______because it goes right to the heart of the social-networking business model. In order to【C2】______users, sites need to offer ways for members to restrict the information about themselves that gets shared with a wider【C3】______. But if a site allows members to keep too much of their information private, there will be less traffic that can be turned into profit【C4】______advertising and various other means,【C5】______the network’s business will suffer.
    There is some evidence that people are starting to become more sophisticated about the way in which they【C6】______their data, which could have longer-term【C7】______for the networks’ growth. Research【C8】______last year showed that some 60% of adults are restricting【C9】______to their online profiles.
    As it happens, the social networks have partly brought this on themselves. In order to offer a better service, many have created【C10】______sets of privacy controls that allow users to switch【C11】______different levels of protection to entrench (保护) their online data. Facebook has excessive controls that can be【C12】______to create different levels of confidentiality. Default settings (默认设置) for younger people on social-networking sites are often more【C13】______than those for adults to ensure they are protected【C14】______unwanted attention.
    Social networks【C15】______applause for developing these fine-grained controls.【C16】______their desire for profit can put them on a【C17】______course with privacy activists, regulators and their users. One bone of contention is social networks’【C18】______to draw attention to their privacy statements. The reason for this might be【C19】______about "privacy reassurance": the worry that alerting people to privacy as a potential issue will make them less inclined to share things,【C20】______robust privacy controls are available.
【C7】
选项 A、influences
B、impressions
C、implications
D、connections
答案C
解析 语义衔接题。结合前文提到人们限制自己的个人信息被分享导致能转变成利润的浏览量减少，从而使网站生意受损可知，人们在个人信息的处理方式上变得更加成熟会对网站的发展产生影响，[C]implications“可能的影响”可以与for连用，故答案为[C]。[A]influences虽然也有“影响”的含义，但其常与on搭配使用，故排除[B]impressions“印象；看法”常与on或of连用；[D]connections作复数名词时表示“熟人；亲戚”。
