Text 2 When people talk about a"north-south divide"in Britain they are usually referring to house prices,employment and the ratio of private-sector to public-sector jobs.The south scores higher on all such measures.But new data from the British Trust for Ornithology（BTO）,a research charity,hints at the growth of another north-south divide-this time to the north's benefit.Every 20 years the BTO produces a superbly detailed atlas of bird life in Britain and Ireland.The 2007 t0 2011 edition is cheery:more species are tallied than in previous atlases,and many birds are increasing in number.Compared with two decades ago,45%of regular native species are ranging more widely while 32%are living in smaller areas;the rest have stayed put.But the most striking news comes from the north.The overall populations of woodland,farmland and migrant perching birds are up in northern England and Scotland but down in the south.The same is true of individual species such as the garden warbler,bullfinch and swallow.The number of cuckoos,a closely-watched species,declined by 63%in England between 1995 and 2010 but by only 5%in Scotland.Raptors are faring especially well in the south,but their numbers are rising in most parts of Britain.Partly this reflects climate change,suggests Simon Gillings of the BTO.Some birds are drawn to warmer winters in Scotland and northem England;visiting migrants may stick around for longer.Hard though it may be to believe during a week of torrential rain,the south is becoming drier,pushing snipe northward.More efficient farming has squeezed some farmland species.Some birds find it harder to make homes in the south,too.Pressure on housing means dilapidated buildings and barns,handy for nesting,have been converted into human dwellings.Between 2006 and 2012 the number of vacant dwellings fell by 17%in London and by 12%in Kent.Over the same period the number of empty houses increased by 16%in Derbyshire and by 10%in Lancashire:Northern mining villages once full of workers are now sparsely populated,points out Ian Bartlett,a birdwatcher in Hartlepool,in north-east England.They have become hot spots for birds and the people who watch them.Culrural difference also plays a part,thinks Mark Cocker,an expert on birds.The"obsession with tidiness"is stronger in the south,he says.Fewer people cultivate gardens;they prefer to cover them in decking and remove weeds from between concrete slabs.Village greens are mowed short.In contrast,Scotland and northern England have more trees,grassland and wind-swept moors.Less popular with humans,rugged parts of the countryside are filling up with a winged population instead.The text mainly discusses_____

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.The word"facile（Line l,Para.4）"is closest in meaning to_____
A、 confusingB、 oversimplifiedC、 persistentD、 radical -
Text 2 When Europe caught America's flu after 2008,bond markets picked off the euro's weakest members one by one.Greece,Portugal,Ireland and Spain were forced into bail-outs.Italy,the euro's third largest economy,tottered.Emergency funds were created,and the European Central Bank（ECB）implied it would create unlimited quantities of cash if needed,and the euro limped on.Today,growth is picking up and unemployment falling.But no one believes that the euro,which lacks the political and fiscal institutions typical of a currency area,can remain half-built forever.Investors are uncertain of its future,and governments have piled on debt since the last crisis,shrinking the space available to respond to the next one.The case for reform is much-talked about.The creation of the euro in 1999 denied its members the option of restoring competitiveness by devaluing.Labour-market mobility and fiscal transfers,which smooth the effects of shocks in other currency areas,were limited by rules and by culture.Bail-outs and belt-tightening were the prescribed solution for governments hit by sudden capital stops,which annoyed everyone:creditors resented opening their wallets;debtors contracted an acute case of austerity fatigue.The currency turned from an instrument of convergence between countries to a wedge driving them apart.Just compare Germany's unemployment rate with Greece's.All this created a legacy of mistrust that haunts the euro zone today.That helps explain why,despite this endless talk of troubles,conversations about euro-zone reform have gone nowhere.Indebted countries like Italy have grown addicted to the ECB's cheap money,ignoring pleas from Mario Draghi,the bank's president,to use the time he has bought them to reinvent their economies.Hardliners like Germany are more convinced than ever of the need for strict rules on spending and structural reform.Anxious officials wonder where the political impetus for a debate on the euro's future might come from.If the euro area is capable of taking advantage of good conditions,best to build confidence slowly.Start with the incomplete banking union,which still lacks a common deposit-insurance scheme（thanks to German objections）,and a backstop for its resolution fund.The much-celebrated capital-markets union,which aims to reduce European firmsJ reliance on banks for finance,is only getting off the ground.Improving cross-border financial flows matters as much as the more contentious fiscal risk-sharing.In time,that might open the way to more radical changes.They will require the sort of political courage for which the euro zone has never been known,but it could turn out to be less painful than some suspect:polls find record support for the single currency among voters,and a surprising appetite for reform.Like self-hating addicts,governments have shivered in the euro zone's halfway house for too long,hooked up to Mr Draghi's monetary medicine and convincing themselves that they deserve no better.It is time to move on.It can be learned from the first paragraph that_____.
A、 the 2008 global financial crisis originated in EuropeB、 euro-zone economy is still in the midst of recessionC、 the ECB has helped euro's weak members step out of troubleD、 the euro is ill-prepared to respond to another crisis
