模仿文本：Canada's former central bank chief Mark Carney takes over in London in just three weeks' time, promising initiatives at the Bank of England not just to control inflation, but to promote growth as well. That's traditionally the job of the politicians in Britain. So what are these new interventionists' role? One we've already seen at the Federal Reserve and the ECB.

译文： 三周后加拿大前中央银行行长马克·卡尔尼将在伦敦就职，允诺将在英格兰银行采取措施，在控制通胀的同时促进经济增长。这原本是英国政客们的职责。那么这些新干涉主义者的角色又是什么呢？美联储和欧洲央行已经执行过这一职能。
