A:INFORMATION B:ALERTING C:SETUP D:CONNECT

A key reason the news media exists with special privileges is to be our watchdogs. Reporters’ charge is to alert us when something is wrong, when human or natural disasters are about to threaten our welfare. When it comes to natural disasters, the news media do a praisable job of reporting the obvious, but not a very good one of preparing the public for what might happen, for alerting us to potential difficulties. When it comes to human disasters, especially problems in government and economic matters, the press has failed miserably. For example, Time magazine finally told the public in a recent cover story what only the most quick observers already knew: "The Great Retirement Ripoff (偷窃): Millions of Americans who think they will retire with benefits are going be shocked. How corporations are picking people’s pockets—with the help of Congress...How can this legal"
Where was the media when each piece of corporate-biased legislation was being passed Why wasn’t Congress afraid to pass such legislation Because the media has decided that news concerning Congress is of little interest to its audience.
TV news managers have believed that economic and social issues are too complicated for the public to grasp. Newspaper editors occasionally print such stories, but mostly they concentrate on human-interest features, consumer health sections and entertainment. Hard news holes are shrinking and investigative journalism is carried out only on occasion. It is too difficult and costly. Besides, it antagonizes advertisers while seldom increasing circulation. Magazines that would look into such subjects seem to be dying out.
The result is that no one is watching the rich and powerful so they can do almost anything with impunity (不受惩罚). Millions of Americans have been robbed in broad daylight while the news media has busied itself with celebrity trials and sensational crime stories. Corporations steal the public blind under legislation authorized by government officials. Companies file for bankruptcy protection, cutting off medical and life-insurance benefits for retirees. It isn’t a new phenomenon. For the most part, today’s press has let down the American public time and time again.
If it seems to be getting worse, it’s because there are so many segments of the media that should be telling us, in an accurate and fair manner, what our elected officials are doing before it’s too late to take action. It’s harder to blame corporations because they make no bones about their mission: make as much money as possible at all costs. Those in Congress are supposed to protect us and look out for our interests. Yet, it appears they constantly help their powerful supporters who often buy their offices for them. No one is doing the right thing. The joke apparently is on all of us—the old and the sick who will have no help in the future and the young burdened with the debt of caring for their impoverished elders for the rest of their lives.
According to the first three paragraphs, the news media do well in ______

A:forecasting the natural disasters, such as earthquake, storm, and so on. B:alerting us to the possibility of some world-scale economic crisis~ C:reporting on the latest development of Indonesian Tsunami. D:disclosing corporations’ illegal behaviors under government legislation.

If there is one thing that could halt the ascent of social networks, it is the thorny question of privacy. This is (1) because it goes right to the (2) of the social-networking business model. In order to attract users, sites need to offer ways for members to restrict the information about themselves that gets shared with a wider (3) . But if a site allows members to keep too much of their information privacy, there will be less (4) that can be turned into profit through advertising and various other means, so the network’s business will (5) .
There is some evidence that people are starting to become more (6) about the way in which they (7) their data, which could have longer-term (8) for the networks’ growth. Research published last year showed that some 60% of adults are restricting (9) to their online profiles.
(10) , the social networks have partly brought this on themselves. In order to offer a better service, many have created (11) sets of privacy controls that allow users to switch between different levels of protection to (12) their online data. Facebook has excessive controls that can be adjusted to create different levels of (13) . Default settings for younger people on social-networking sites are often more (14) than those for adults to (15) they are protected from unwanted attention.
Social networks (16) applause for developing these fine-grained controls. But their desire for profit can put them on a (17) course with privacy activists, regulators and their users. One bone of contention is social networks’ (18) to draw attention to their privacy statements. The reason for this might be concern about "privacy reassurance": the worry that (19) people to privacy as a potential issue will make them less (20) to share things, even if robust privacy controls are available.

Video games have become increasingly realistic, especially those involving armed combat. America’s armed forces have even used video games (1) recruitment and (2) tools. But the desire to play games is not the (3) why the United States Air Force recently (4) a procurement request for 2,200 Sony PlayStation 3 (PS3) video-game consoles. It intends to link them (5) to build a supercomputer that will (6) Linux, a free, open-source operating system. It will be used for research, including the development of high-definition imaging systems for radar, and will cost around one-tenth as much as a conventional supercomputer. The air force has already built a smaller computer (7) a cluster of 336 PS3s.
This is merely the latest example of a(n) (8) trend. There is a long tradition of technology developed for military use filtering (9) to consumer markets: satellite-navigation systems (10) to guide missiles can also help hikers find their way, and head-up displays have (11) from jet fighters to family cars. But technology is increasingly moving in the other (12) , too, as consumer products are (13) for military use.
Traditionally the military has preferred to develop and control its own technology, not just for tactical advantage but also to (14) that equipment was tough and (15) enough for those whose lives would depend on it. That began to change after the cold war as defence budgets became (16) and the development of (17) industrial and consumer products accelerated. As some of these technologies have become commoditized products which are (18) to everyone—friend and foe alike—there seems less (19) not to buy them and use the savings for more critical equipment that needs to be built-to-order. And consumer products can often be tweaked to make them more rugged or (20) when necessary.
