  • [单选题]阅读下列短文,从每题所给的A、B、C、D四个选项中,选出最佳选项,回答46-50题。 Tens of thousands of theatre tickets will be given away to young people next year as part of a government campaign to inspire a lifelong love for theatre.The plan to offer free seats to people aged between 18 to 26—funded with £2.5 million of taxpayers’ money—was announced yesterday by Andy Burnham, the Culture Secretary. It received a cautious welcome from some in the arts world, who expressed concern that the tickets may not reach the most underprivileged.
  • A. The plan comes as West End theatres are enjoying record audiences, thanks largely to musicals teaming up with television talent shows. Attendances reached. 13.6 million in 2007, up 10 percent on 2006, itself a record year. Total sales were up 18 percent on 2006 to almost £470 million.
    B. One theatre source criticised the Government’s priorities(优先考虑的事) in funding free tickets when pensioners were struggling to buy food and fuel, saying: “I don’t know why the Government’s wasting money on this. The Yong Vic, as The Times reported today, offers excellent performances at cheap prices.”
    C. There was praise for the Government’s plan from Dominic Cooke of the Royal Court Theatre, who said: “I support any move to get young people into theatre, and especially one that aims to do it all over England, not just in London.”
    D. Ninety-five publicly funded theatres could apply for funding under the two-year plan. In return, they will offer free tickets on at least one day each week to 18 to 26-year-olds, first-come, first-served. It is likely to be on Mondays, traditionally a quiet night for the theatre.
    E. Mr. Burnham said: “A young person attending the theatre can find it an exciting experience, and be inspired to explore a new world. But sometimes people miss out on it because they fear it’s ‘not for them’. It’s time to change this perception.”
    F. Jeremy Hunt, the Shadow Culture Secretary, said: “The real issue is not getting enthusiastic children into the theatre, but improving arts education so that more young people want to go in the first place. For too many children theatres are a no-go area.”
    G. 第11题:Critics of the plan argued that( )
    H. the theatres would be overcrowded

    J. pensioners wouldn’t get free tickets
