Big Ben is the nickname for the great bell of the clock in London. The name was given in honor of Sir Benjamin Hall, who was in charge of the works when the bell was installed in 1856. The clock has become a symbol of the United Kingdom and London. When a television or film-maker wishes to quickly show a non-UK audience a certain location in Britain, a popular way to do so is to show an image of the Clock Tower. The Clock Tower is also often voted as the Most Iconic London Film Location. The Clock Tower is a focus of New Year celebrations in the United Kingdom, with radio and TV stations tuning to its chimes (报时钟声) to welcome the start of the year. Londoners who live an appropriate (适当的) distance from the Clock Tower and Big Ben can, by means of listening to the chimes both live and on the radio or television, hear the bell strike thirteen times on New Year’s Eve. This is possible due to what amounts to an offset between live and electronically transmitted chimes since the speed of sound is much slower than the speed of radio waves. Guests are invited to count the chimes aloud as the radio is gradually turned down. The Clock Tower has appeared in many films, most notably in the 1978 version of The Thirty-Nine Steps , in which the hero attempted to halt the clock’s progress (to prevent a linked bomb blowing up) by hanging from the minute hand of its western face. It was also used in the film, Shanghai Knights , starring Jackie Chan and Owen Wilson, and was depicted (描述) as being destroyed in Aliens of London . In the Walt Disney film The Great Mouse Detective , it is even shown being destroyed by a UFO! 1. From Paragraph 2, we know that Big Ben is .
