31.8C (90F)

The chimes of Big Ben were silenced for over an hour on Friday night but the cause remains a mystery. The Palace of Westminster's 147-year-old clock, considered to be one of the most reliable in the world, stopped at 10:07 pm. The minute hand started to move again slowly but stalled a second time at 10:20 pm where it is reported to have remained for 90 minutes before the hands were reset. It was thought the hot weather may have been to blame. Temperatures in London reached a high of 31.8C (90F) yesterday and forecasters declared it the hottest May day since 1953. But an engineer at the palace said the cause was unclear. He said, "We've been told there was a minor glitch but then it was started up again."
今天一位工程师说，大本钟在周五晚上沉默了一个小时至今仍然是个谜。 被认为是世界上最可靠的，威斯敏斯特宫的147岁高龄的钟，在下午10.07点停了。 据说钟停了90分钟，直到指针被重新设置，分针才开始继续缓慢地移动，但是到了下午10.20的时候时间停滞了一秒。 有人认为可能是炎热的天气导致的。昨天伦敦的气温高达31.8摄氏度（90华氏度），预报员宣布这可能是1953年以来最热的一天。 但是一位皇宫工程师说原因尚不清楚。他说：“我们被告知这是一个小问题，但是后来它又自动重新开始了。”
