It was my first day in Hangzhou, the Chinese city famous for its natural beauty and history and I didn't have much time to spare. I wanted to see     1     much of the city as possible in the two days     2     I was to return to Guangzhou. My first task was to decide where to go and     3     to get there. I took out my guide book in which there was a lot of information about the city's well-known tourist     4    (attract) and started to read. At that moment an attractive young lady     5     noticed my book, came up to me and introduced     6    (her). She said her name was Miss Bai. She kindly offered to show me     7     the city. I was delighted and was about to accept her proposal when she suggested we first     8    (go) to the West Lake and walk along the Broken Bridge. I quite liked the idea of visiting the West Lake but wasn't so sure about crossing the Broken Bridge.    9     it was broken, did she expect me to jump across？And I couldn't swim, so if I fell in then I would drown. That was definitely not an attractive idea so I politely declined her invitation,     10    (close) my book and walked away.

2 . 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 2 mm every year, making relics of history go under the surface of water and destroying architecture. Experts warn that without intervention, 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 laces severe influence from increasing foot traffic. The Peruvian government 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

Unfortunately, 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.
