Europe's best known landmarks - including the Eiffel Tower, Big Ben and Rome's Colosseum - fell dark Saturday, following Sydney's Opera House and Beijing's Forbidden City in joining a global climate change protest, as lights were switched off across the world to mark the Earth Hour event.

　　上周六，世界各地纷纷熄灯响应“地球一小时”、抵御全球气候变化的活动。悉尼歌剧院、北京故宫，以及埃菲尔铁塔、大本钟和罗马圆形大剧场等欧洲著名地标建筑相继熄灯。

　　In the United States, the lights went out at the Empire State Building in New York, the National Cathedral in Washington, and the Coca-Cola headquarters in Atlanta.

　　美国纽约的帝国大厦、华盛顿的国家大教堂、亚特兰大的可口可乐公司总部等建筑也在当晚熄灭了灯光。
