Big Ben's silence baffles engineers	倫敦大本鐘熱得走不動(dòng)了
Big Ben, the world-famous clock tower at the Houses of Parliament in London, seen here in February 2005, stopped late Friday night, and nobody is quite sure why, officials said.(AFP) Big Ben, the landmark London clock renowned for its accuracy and chimes, stopped ticking for 90 minutes, an engineer said Saturday. Officials do not know why the 147-year-old clock on the banks of the River Thames stopped at 10:07 p.m. Friday. It resumed keeping time, but stalled again at 10:20 p.m. and remained still for about 90 minutes before starting up again, a spokeswoman for the House of Commons said on condition of anonymity. There has been speculation a recent spell of hot weather may have been to blame. Temperatures in London reached 90 Saturday, and forecasters called it England's hottest day in May since 1953. Big Ben, which is operated by the Palace of Westminster, survived attacks by German Luftwaffe bombers during World War II, continuing to mark the time to within 1 1/2 seconds of Greenwich Mean Time. However, the clock has experienced occasional problems. In 1962, snow caused the clock to ring in the New Year 10 minutes late. In 1976, the clock stopped when a piece of its machinery broke. Big Ben also stopped on April 30, 1997, and once more three weeks later. Big Ben is actually the clock's 13-ton bell, which was named after Sir Benjamin Hall, the British commissioner of works at the time the clock was built. The official name for the Gothic tower holding Big Ben is St. Stephen's Tower. Standing 315 feet tall, it was completed in 1858 after an 1834 fire destroyed most of the Palace of Westminster.
