模仿文本：Now for more than 150 years, Big Ben, or the Great Westminster Clock, to give it its proper name, has kept time outside the Houses of Parliament in London. It must be one of the most iconic clocks in the world. And the man who has to keep it ticking over is Paul Roberson.

 

译文：大本钟，本名威斯敏斯特宫钟，坐落在英国伦敦国会大厦外，经历了150余年，以其准时而闻名于世。它是世界上标志性的钟表之一。而维持它嘀嗒运转的就是保罗·罗伯逊。
