Text 1 Smartphones have by now been implicated in so many crummy outcomes-car fatalities,sleep disturbances,empathy loss,relationship problems,failure to notice a clown on a unicycle-that it almost seems easier to list the things they don't mess up than the things they do.Our society may be reaching peak criticism of digital devices.Even so.emerging research suggests that a kev Droblem remains underaDDreciated.It involves kids'development,but it's probably not what you think.More than screen-obsessed young children,we should be concerned about tuned-out parents.Yes,parents now have more face time with their children than did almost any parents in history.Despite a dramatic increase in the percentage of women in the workforce,mothers today astoundingly spend morc time caring for their children than mothers did in the 1960s.But the engagement between parent and child is increasingly Iow-quality,even ersatz.Parents are constantly present in their children's lives physically,but they are less emotionally attuned.To be clear,I'm not unsympathetic to parents in this predicament.My own adult children like to joke that they wouldn't have survived infancy ifl'd had a smartphone in my clutches 25 years ago.To argue that parents'use of screens is an underappreciated problem isn't to discount the direct risks screens pose to children:Substantial evidence suggests that many types of screen time（especially those involving fast-paced or violent imagery）are damaging to young brains.Today's preschoolers spend more than four hours a day facing a screen.And,since 1970,the average age of onset of"regular"screen use has gone from 4 years to just four months.Some of the newer interactive games kids play on phones or tablets may be more benign than watching TV or YouTube,in that they better mimic children's natural play behaviors.And,of course,many well-functioning adults survived a mind-numbing childhood spent watching a lot of cognitive garbage.（My mother-unusually for her time-prohibited Speed Racer and Gilligan's Island on the grounds of insipidness.That I somehow managed to watch every single episode of each show scores of times has never been explained.）Still,no one really disputes the tremendous opportunity costs to young children who are plugged in to a screen:Time spent on devices is time not spent actively exploring the world and relating to other human beings.
According to Paragraph 4,we can learn that risks of use of screen______

A.shouldbeviewedcorrectly
B.needmorecredibleevidence
C.arehigheramongparents
D.areoverestimatedamongchildren

Text 1 Utopianism in politics gets a bad press.The case against the grand-scale,state-directed kind is well known and overwhelming.Utopia,the perfect society,is unattainable,for there is no such thing.Remaking sociery in pursuit ofan illusion not only fails,it leads swiftly to mass murder and moral ruin.So recent history grimly attests.Although true,that is just half the story.Not all modern Utopians aim to seize the state in order to cudgel the rest of the world back to paradise.Plenty of gentler ones want no more than to withdraw from the mainstream and create their own micro-paradise with a few like-minded idealists.Small experiments in collective living swept America,for example,early in the 19th century and again late in the 20th.Most failed or fell short.None lasted.A11 were laughed at.Yet in this intelligent,sympathetic history,Chris Jennings makes a good case for remembering them well.Politics stultifies,he thinks,when people stop dreaming up alternative ways oflife and putting them to small-scale test.Though with occasional glances forward,Mr.Jennings focuses largely on the 19th century.At least 100 experimental communes sprang up across the young American republic in the mid-1800s.Mr.Jennings writes about five exemplary communities:the devout Shakers,Robert Owen's New Harmony,the Fourierist collective at Brook Farm,Massachusetts,the Icarians at Nauvoo,Illinois,inspired by a French proto-communist,Etienne Cabet,and the Oneida Community in New York state practising Bible communism and complex marriage .The Shakers'founder was a Manchester Quaker,Ann Lee,a devout mother worn out by bearing dead or dying ctuldren.In 1774 she lefi for the New World,determined to forswear sex and create a following to share her belief.An optimistic faith in human betterment,hard work and a reputation for honest Lrading helped the Shakers thrive.At their peak in the early 19th century,they had perhaps 5,000 members scattered in some 20 villages across eight states.They counselled celibacy,to spare women the dangers of child-bearing,made spare,slim furniture,now treasured in museums,and practised a wild,shaking dance that was taken as a sign ofbenign possession by the Holy Spirit. Paradise Now is more than a record of failed hopes.Some ideas spread to the mainstream.Fourier's feminism is a good example.Fourierist communes foundered across the New World and Old;his ideas about gender equality lived on.No society could improve,Fourier believed,until women's lot improved. The best countries ,he wrote, have always been those which allowed women the most freedom. That is a common thought today.It was radical when Fourier wrote it in I 808.Women more generally are at the centre of the Utopian story.Some communes he writes about were democratic,some authoritarian.None was patriarchal.Mr.Jennings's book is rich in fond hopes and improbable ventures.Rather than nudging readers to mock,which is easy,the author reminds them instead to remember that the maddest-sounding ideas sometimes become motherhood.According to the text,most gentle ones want to create______

A.theirowncommune
B.violentworld
C.theirownregime
D.small-mindedparadise
