模仿文本： Half of us live in one of the world's great urban sprawls, the concrete and glass habitats we create for ourselves. Our cities have spread and replaced wildlands, and they roar and blaze with the energy from fossil fuels. They're colossal and sometimes magnificent. But how substantial are they? Will they stand the test of geological time? 

 

译文： 我们当中有一半的人居住在那些遍布全球的了不起的城市地区，也就是我们用水泥和玻璃为自己建造的居所。我们的城市不断扩展，依靠消耗化石燃料产生的能量制造喧闹之声，发出耀眼之光，取代了荒野。它们庞大无比，有时还很壮观,不过它们有多么坚固结实呢？它们能经受得了地质时期的考验吗？
