3.Text 2 Should we be thinking of Facebook as a news site?Is that how Facebook thinks of itself?No,not primarily,Facebook now says.In a document posted on Wednesday,the company explained,for the first time,the"values"that govem its news feed,the scrolling list of posts that Facebook presents to its l.65 billion users every time they log on.Though it is couched in the anodyne language of a corporate news release,the document's message should come as a shock to everyone in the media business.According to these values,Facebook has a single overriding purpose,and it isn't news.Facebook is mainly for telling you what's up with your friends and family.Adam Mosseri,the Facebook manager in charge of the news feed,said in a recent interview that informing and entertaining users was also part of the company's mission.But he made clear that news and entertainment were secondary pursuits."We think more,spend more time and work on more projects that try to help people express themselves with their friends or learn about their friends or have conversations with their friends,"he said.As if to underscore the point,the company is making a tweak to its news feed ranking system to increase the prominence ofcoiitent from your friends and family over posts by news companies and other organizations.It is also waming news companies that their traffic might decline as a result of the change.These moves highlight a truth that tends to get lost in commentary about the social network's influence over the news:At Facebook,infonrung users about the world will always take a back seat to cute pictures of babies..Because Facebook does not think ofitself primarily as a news company,it seems to want us to stop expecting it to act like one.Whether we should,though,is a more complicated matter.The company has long been hounded by journalists and activists over its power to shape the news through its algorithms,or the code that determines which stories you see,in the news feed.The question of how to think about Facebook's role in the news-and whether we should demand the same standards of accuracy,objectivity,transparency and fairness that we expect from traditional outlets-may be the primary puzzle ofour new media age.According to Facebook,the values outlined in the document have been the informal governing philosophy of its news feed since it was started a decade ago,and Mr.Zuckerberg and Chris Cox,Facebook's chiefproduct officer,were deeply involved in drafiing the new document.30.The best title for this text could be.A.Facebook-a News Giant That Would Rather Show Us Baby Pictures B.Facebook Is Reluctant to Be a News Website C.Facebook,a New Bom Baby in the Age oflntemet D.Facebook's Mr.Zuckerberg and Chris Cox

    Practice 1  The Microsoft’s rise to prominence set off an explosion in demand for all things digital and sparked the Internet boom, because every investor looked at the Internet and concluded that if everything was going to be digitized—data, inventories, commerce, books and entertainment—and transported and sold on the Internet, the demand for Internet-based products and services would be infinite. This led to the dot-tom stock bubble and a massive overinvestment in the fiber-optic cable needed to carry all the new digital information. As a result, some companies became bankrupt and some were struggling to stay in business. Keep in mind that cyberspace promises both opportunities and high risks.
