你敢站在“透明陽臺”嗎？

Visitors to the Sears Tower's new glass balconies all seem to agree: The first step is the hardest.The balconies are suspended 1,353 feet in the air and jut out four feet from the building's 103rd floor Skydeck. Their transparent walls, floor and ceiling leave visitors with the impression they're floating over the city.

　　美國芝加哥希爾斯大廈（Sears Tower）在第103層樓創建一個別開生面的陽臺“The Ledge”，它的特點是墻壁、地板和天花板都是透明玻璃，要走進這個離開地面約412公尺的陽臺可不是件簡單的事，除非你有過人的膽識。一旦克服這道心理障礙，你就可一邊欣賞芝加哥市景，一邊感受居高臨下的滋味.
