[单选题]Text 3 West London,Friday night,9 pm.In the Redemption bar,music hums and candles flicker.A barman shakes cocktails under a neon sign.But the noisy drinking often associated with British pubs at the weekend is absent.Although the cocorita is served,it contains no alcohol.Redemption is one of a small but growing number of drinkeries that serve no liquor.Worries about drinking are on the rise.Hospitals complain that alcohol-related admissions are soaring;some police chiefs have called for new powers to tackle disorderly drunks.On February 4th the Home Office announced a new plan that ought to stop retailers from selling alcoholic drinks below cost-something they occasionally do to attract shoppers.This,said Norman Baker,the Liberal Democrat,would"stop the worst examples of very cheap and harmful drink".Yet Britain is in many ways becoming more absterruous.In 2001 the average household consumed 1.5 litres of alcoholic drinks a week;by 2011,the figure had fallen t0 1.I litres.The young in particular seem to be giving up boozing:over the same period,the number of young men drinking heavily at least once a week feU from 37%t0 22%;women became less sozzled,too.Dry bars benefit from this fad:Redemption's customers doubled between December and January.Abstemious bars have also opened in Liverpool and Nottingham.Unlike many caf6s,they stay open late.They simulate hars in other ways,with live music,comedy acts and films to pull in customers.When the lights go down and the DJ plays at Sobar,which opened in Nottingham in January,it looks like any city bar,hopes Alex Gillmore,the manager.Redemption misses the huge profits made on alcohol,but temperance brings its own benefits.Business remains sleady throughout the week rather than spiking at the weekend,says Catherine Salway,its founder.Sobar is linked to a do-gooding drug and alcohol charity.But ordinary bars are becoming a little drier,too,out of business sense rather than temperance principle.Pubs can make almost as much selling food as drink-and more are serving it.Both in pubs and at home,less boozy drinks are beconung popular.Total sales of beer by volume dropped slightly in the year to January,but those of the weaker kinds jumped 32%,according to a market-research firm.Sales of"adult"sparkling soft drinks are grwing too.Perhaps the caf6-culture British politicians have so long yearned for is at last emerging.

A.have some positive effects

C.totally eliminate heavy drinkers
D.slop retailers from seUing liquor
