2008年夏天，中国举办了北京奥运会。从8月份开始，成千上万的顶尖运动员和数以百万计的奥运迷就涌入北京。为了准备奥运会，北京规划了很多新建筑，包括体育场馆、为奥运迷们准备的宾馆，还有供运动员和教练居住的奥运村。在这些新建筑中，有一些和世界上其他建筑相比是独树一帜的，比如国家体育场“鸟巢”（the“Bird's Nest”）。尽管这座体育场是由钢和混凝土（steel and concrete）建成的，但它看起来就像一个由树枝筑成的巨大鸟巢。
In the summer of 2008, China hosted the Beijing Olympics. Since August, thousands of top athletes and millions of Olympics fans had poured into Beijing. To prepare for the Olympics, Beijing had planned a lot of new buildings, including stadiums, hotels for the Olympics fans, and the Olympic village where the athletes and coaches would live. Among these new buildings, some are unique compared with other buildings in the world, for example, the National Stadium which is called the“Bird's Nest”. Even though it's made of steel and concrete, the stadium looks just like a giant nest made with branches.
