Big Ben is the nickname for the great bell of the clock at the north end of the Palace of Westminster in London,[1] and often extended to refer to the clock and the clock tower.[2] The tower is now officially called the Elizabeth Tower, after being renamed to celebrate the Diamond Jubilee of Queen Elizabeth II. The Elizabeth Tower holds the largest four-facedchiming clock in the world and is the third-tallest free-standing clock tower.[3] The tower was completed in 1858 and had its 150th anniversary on 31 May 2009,[4] during which celebratory events took place.[5][6] The Elizabeth Tower has become one of the most prominent symbols of both London and England and is often in the establishing shot of films set in the city.大本钟(英语:Big Ben,或翻译成大笨钟、大鹏钟)是英国国会会议厅附属钟楼的大报时钟的昵称,也常代指该钟所在的钟楼 。[1]大本钟坐落在英国伦敦泰晤士河畔的威斯敏斯特宫钟塔上,是伦敦的标志之一。钟楼高95米,钟直径9英尺,重13.5吨。每15分钟响一次,敲响威斯敏斯特钟声。自从兴建地铁朱比利线之后,大本钟受到影响,最近测量显示大本钟朝西北方向倾斜约半米[2]。大本钟的命名来源众说纷纭,有一种说法称大本钟的名字来自于本杰明·豪尔爵士。大钟于1858年4月10日建成,是英国最大的钟。塔起码有320英尺高(约合97.5米),分针有14英尺长(约合4.27米),大本钟用人工发条,国会开会期间,钟面会发出光芒,每隔一小时报时一次。每年的夏季与冬天时间转换时会把钟停止,进行零件的修补、交换,钟的调音等。大本钟的可靠性毋庸置疑,自从建成,伦敦格林威治天文台的官员每天两次派人校对此钟。不过有一次它把时间报错了,因为一名在大本钟上作业的油漆粉刷工在钟面上挂了一个油漆桶,把钟弄慢了。[来源请求]2009年6月1日,欢庆启用150周年。2012年6月26日,英国政府宣布为庆祝伊丽莎白二世登基60周年,将大本钟所在的钟楼正式改名为伊丽莎白塔。[3]。
