　　Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs恐龙were on the Earth for over 160 million years.

　　2.The tower of Big Ben London’s most famous building,has always leaned 倾斜 slightly, but construction work on a new line for the London Underground seemed likely to give the tower a real lean. Engineers have had to prop up 支撑 its base to prevent it from damaging the rest of the Houses of Parliament.

　　To control the tower’s movement, engineers pumped grout 水泥浆 into the soil under the tower. The tower now leans an extra few centimetres, but the lean can only be seen by the most sharp-eyed observer.

　　Between 1995 and 1997, to lengthen the Jubilee line of the Underground, builders dug a 40-metre-deep hole just 31 metres north of the clock tower. And the new tube underground tunnels were even nearer to the tower. John Burland, who recently helped stop the increasing lean in the Leaning Tower of Pisa and was an adviser to the Jubilee line project, believed the work would affect the tower. In his opinion, no further lean should go beyond a safety limit of 27.5 millimetres over the existing lean of 220 millimetres.
