An Englishman was showing a foreign visitor around London. "What's that strange building?" asked the visitor. "That's the Tower of London." "I see. How long did it take to build it?” “About 500 years." "In my country we can build it in five months." said the visitor. A short time after that, they come to St. Paul's Cathedral (大教堂)."Very interesting, "said the visitor, "How long did it take to build it?  Nearly forty years." said the Englishman. "In my country we can finish it in forty days." said the visitor. This went on all day. They visited most of the best known buildings in the city. Every time they saw a new one, the visitor asked what it was and how long it took to build it. Then he said that they could do the same things much faster in his country. At last the Englishman got angry with the visitor though he tried not to show it. A few days later they came to the House of Parliament(议会大厦) and the visitor asked his usual question. "What's that?” The Englishman answered, "I've no idea. It wasn't there last night."
