活动组织者于本周二称,全球24个城市将于下个月“陷入黑暗”。因为这些城市的家庭和企业届时将集体熄灯,以引起人们对全球变暖问题的关注。“地球一小时”活动于去年在澳大利亚最大的城市悉尼首次举行。当时全市约有220万居民集体熄灯,没有灯光的悉尼歌剧院沐浴在月光里,海湾大桥也熄灯响应。 Event organizers said on Tuesday that 24 cities around the world will be “dark” next month. Because families and businesses in these cities will collectively turn off lights to raise people’s concern about global warming. The “Earth Hour” event was first held last year in Sydney, Australia’s largest city. At that time about 2.2 million residents of the city switched off their lights collectively. The unlit Sydney Opera House bathed in the moonlight and the Bay Bridge turned off.
