“9·11”恐怖袭击事件十周年纪念日来临之际，在纽约世贸中心原址上建立的“9·11”纪念碑和纪念馆将首次对外开放。

The National September 11 Memorial opens to the public Monday in New York City, more than a decade after the twin towers of the World Trade Center were taken down by terrorists. 
    Visitors will see for the first time the reflecting pools surrounded by bronze panels engraved with the names of those lost on September 11, 2001 and in the 1993 World Trade Center bombing. Sitting in the footprints of where the towers once stood, the dark granite（花岗岩） cube-shaped pools, each about a half-hectare in size, are the largest man-made waterfalls in North America.
