约2000年前,为了举行角斗、战争剧,以及其它公开演出,罗马圆形大剧场建成了。现在,这个5000座的石头混凝土建筑以另一种方式为罗马服务:充当交通环岛。

website: http://www.nationalgeographic.com/ From 33 founders in 1888, to a worldwide team today of thousands of dedicated individuals, National Geographic stands at the forefront of exploration, research, and scientific discoveries. The results educate people everywhere, helping them consider today's ever changing world and their place in it. Philanthropic support is critical, propelling projects and expeditions that inspire us all to care about the planet. The National Geographic Society has supported and chronicled the achievements of renowned explorers and researchers for more than a century. In doing so, the Society developed many related programs for grant-making, scientific research, education, and public outreach. In 1996, these diverse programs were organized under a single banner—Mission Programs—recognizing that all the efforts were focused on the same core mission: to increase and diffuse geographic knowledge while promoting conservation of the world's cultural, historical, and natural resources. These core scientific and education programs operate behind the scenes of the more recognizable arms of the National Geographic, from the Yellow Border magazine to the National Geographic Channel, providing additional media content.
