　　A

　　Mother Nature is a cruel mistress. Why? Read on to find the answer.

　　Venice

　　This iconic city is sinking rapidly. The canals that make up the streets of Venice rise 2mm every year, making relics of history go under the surface of water and destroying architecture. Experts warn that without intervention (干预), this city will disappear back into the water at an even faster rate, consumed by rising sea level from melting polar ice caps.

　　Machu Picchu

　　These Incan ruins have drawn adventurous tourists into the mountains of South America. The forces of natural erosion have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic. The Peruvian government recently suggested a cable car that would cut out the intense hike up to the ruins, making the site instantly accessible to millions, but the future of Machu Picchu remains uncertain.

　　Glacier National Park

　　Perhaps you've heard that the ice caps are melting. But nowhere is more apparent in the United States than in Glacier National Park. Estimates indicate that the glaciers that are part of the beauty of this national landmark will disappear entirely in the next two decades.

　　The Great Barrier Reef

　　Hidden from view beneath the waves, the Great Barrier Reef has been rapidly dying off. Nearly fifty percent of coral which once occupied a large area is gone, destroyed by pollution and disease.

　　语篇解读：本文是应用文。文章主要介绍了世界上濒临消失的几个旅游胜地。
