Text 4 The revelations we publish about how Facebook's data was used by Cambridge Analytica to subvert the openness of democracy are only the latest examples of a global phenomenon.YouTube can not only profit from disturbing content but in unintended ways rewards its creation.The algorithms that guide viewers to new choices aim always to intensify the experience,and to keep the viewer excited.Recent research found that the nearly 9,000 YouTube videos explaining away American school shootings as the results of conspiracies using actors to play the part of victims had been watched,in total,more than 4bn times.Four billion page views is an awful lot of potential advertising revenue;it is also,in an embarrassingly literal sense,traffic in human misery and exploitation.None of these problems is new,and all of them will grow worse and more pressing in the coming years,as the technology advances.Yet the real difficulty is not the slickness of the technology but the willingness of the audience to be deceived and its desire to have its prejudices gratified.Many of the most destructive videos on YouTube consist of one man roaring into a camera without any visual aids at all.Twitter uses no fancy technology yet lies spread across that network six times as fast as true stories.Although Twitter and YouTube pose undoubted difficulties for democracies,it is Facebook that has borne the brunt of recent criticism,in part because its global ambitions have led it to expand into countries where it is essentially the only gateway to the wider internet,The company's ambitions to become the carrier of all content（and thus able to sell advertising against everything online）have led it inexorably into the position of being the universal publisher.The difficulties of this position cannot be resolved by the facile idea of the"community values"to which Facebook appeals-and,anyway,that only begs the question:"Which community?"Mark Zuckerberg talks about a"global community"but such a thing does not exist and may never do so.Communities have different values and different interests,which sometimes appear existentially opposed.Almost all will define themselves,at least in part,against other communities.The task of reconciling the resulting conflicts is political,cultural and even religious;it is not technological at all.For a private American advertising company to set itself up as the arbiter of all the world's political and cultural conflicts is an entirely vain ambition.Into the vacuum left by Facebook's waffle,nation states are stepping.Many are keen to use surveillance capitalism for direct political ends.They must be resisted.The standards by which the internet is controlled need to be open and subject to the workings of impartial judiciaries.But the task cannot and will not be left to the advertising companies that at present control most of the content-and whose own judgments are themselves almost wholly opaque and arbitrary.According to Paragraph 2,the problem's real challenge seems to be the fact that_____A.technology is evolving too fastB.fake stories can hardly be curbedC.platforms have put little efforts in itD.viewers often welcome false content

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 PicturesB.Facebook Is Reluctant to Be a News WebsiteC.Facebook,a New Bom Baby in the Age oflntemetD.Facebook's Mr.Zuckerberg and Chris Cox

Compared with other areas of our social lives,we tend to boast far more on social media.For instance,few of us will stand on a neighborhood corner and declare how accomplished we are or how much we love our spouse.On Facebook,however,we have no uneasiness about routinely posting photographs of intimate family gatherings,foreign vacations,and fancy meals.What's more,many of us share boasts with hundreds or even thousands of social media connections,with little knowledge or concern about who's seeing them or what effect it has on them.Despite the risk of negative effects,we can't help boasting on social media because,as psychologists have argued,boasting satisfies fundamental human motives of creating a favorable first impression with strangers,and building a positive image among those who know us.In our vast social media spheres,boasting is also a good way,or even possibly the only way,to attract attention.
It's almost impossible to go through life without experiencing some kind of failure.People who do so probably live so cautiously that they go nowhere.Put simply,they’re not real living at all.But,the wonderful thing about failure is that it's entirely up to us to decide how to look at it.We can choose to see failure as"the end of the world,"or as proof of just how inadequate we are.Or,we can look at failure as the incredible learning experience that it often is.Every time we fail at something,we can choose to look for the lesson we're meant to learn.These lessons are very important;they're how we grow,and how we keep from making that same mistake again.Failures stop us only if we let them.Failure can also teach us things about ourselves that we would never have learned otherwise.For instance,failure can help you discover how strong a person you are.Failing at something can help you discover your truest friends,or help you find unexpected motivation to succeed.

资料：The increasing amount of personal information that can be collected by computer programs that track how people use Facebook has been revealed by an extensive academic study.Such programs can show undisclosed private information such as Facebook users' sexuality, drug-use habits and even whether their parents separated when they were young, according to the study by the University of Cambridge academics.In one of the biggest studies of its kind scientists from the university’s team and a Microsoft-funded research center analyzed data from 58,000 Facebook users to predict traits and other information that were not provided in their profiles.The algorithms were 88 per cent accurate in predicting male sexual orientation, 95 per cent for race and 80 per cent for religion .And political leanings, personalitytypes and emotional stability were also predicted with accuracy ranging from 62-75 per cent.The study highlights growing concerns about social networks and how data trails can be mined for sensitive information even when people attempt to keep information about themselves private ：Less than 5 per cent of users were connected with explicitly gay groups.Michal Kosinksi ，one of the report’s authors told the Financial Times that the university’s techniques could easily be replicated by companies to inter personal attributes a person did not wish to share such as sexual orientation or political views:”We used very simple and generic methods :Marketing companies and internet companies could spend much more time and resources and hence get much higher accuracy than we did.The report also revealed some unexpected correlations such as people who liked ‘curly fries’ having higher IQs while those Who like Facebook’s “Sliding on Floors With Your Socks On”page were unlikely to use drugs.According to Michal Kosinksi,which of the following is true according to the passage?A.The study draws people’s attention for private informationB.information can be predicted correctly in the studyC.some personal information may be collected and used by some companiesD.if people attempt to keep personal information private, things will change

共用题干Looking to help the environment?Consider the following simple ideas.Turn off electrical devices when they're not being used.Turning off,rather than leaving on stand-by,things like your TV and computer will save huge amounts of energy. With this,we can all help reduce the amount of carbon dioxide emitted into the earth's atmosphere,thereby reducing pollution and global warming.Share your car.Rather than traveling to work alone,why not arrange car-sharing with one or more of your friends or colleagues?To give you an example,if you drive a fashionable car,you will use more energy in a year than you would leaving your fridge open for seven years,or your TV on for thirty-two years!Imagine the savings if you shared your car with 2,3 or even 4 other people!Refuse junk mail.While we all complain about how much junk mail we get,we very rarely do anything about it. The mail continues to go straight from our letter-boxes into the garbage bin-with 99% of it not even opened.What can you do about this?There are various websites where you can register to receive no junk mail.As well as saving time,you'll also be doing a lot for the environment. Each year,100 million trees are used to produce junk mail. 250,000 homes could be heated with one day's supply of junk mail.There are many other everyday changes you can make to help the environment. They will cost you nothing,and many will actually save you money!Why not give it a try?We can all help, if we really want to.

Plan and write an essay in which you develop your point of view on this issue. Support your position with reasoning and examples taken from your reading, studies, experience, or observation.
