A
Recently, winter floods on the rivers of central Europe have been among the worst for 600 to 700 years, and dams and dykes (protective sea walls) have failed to solve the problem. Traditionally, river engineers have tried to get rid of the water quickly, draining it off the land and down to the sea in rivers reengineered as high-performance drains. But however high they build the artificial riverbanks, the floods keep coming back. And when they come, they seem to be worse than ever.

答案:F
原文定位:Tough new rules for new developments mean that drains will be prevented from becoming overloaded after heavy rains. Architects of new urban buildings are diverting rainwater from the roofs for use in toilets and the irrigation of roof gardens, while water falling onto the ground is collected in ponds, or passes underground through porous paving
答案:C
原文定位:For a long time engineers have erased its backwaters and cut it off from its plain. The aim was partly to improve navigation, and partly to speed floodwaters out of Alps and down to the North Sea
答案:B
原文定位:Back in the days when rivers took a winding path to the sea, floodwaters lost force and volume while meandering across flood plains and inland deltas, but today the water tends to have a direct passage to the sea
答案:D
原文定位:Similar ideas are being tested in Austria, in one of Europe's largest river restorations to date. The engineers calculate that the restored flood plain of the Drava River can now store up to 10 million cubic metres of floodwater, and slow down storm surges coming out of the Alps by more than an hour, protecting towns not only in Austria, but as far downstream as Slovenia and Croatia
答案:E
原文定位:Since that time, the Dutch have broken one of their most enduring national stereotypes by allowing engineers to punch holes in dykes. They plan to return up to a sixth of the country to its former waterlogged state in order to better protect the rest
答案:G
原文定位:It may sound expensive, until we realise how much is spent trying to drain cities and protect areas from flooding, and how little this method achieves
答案:A It aims to slow the movement of water to the sea.,C It will cost more than twice as much as former measures.
原文定位:In Zaandanse Vliet, the Netherlands, they have even removed parts of the concrete dyke to let the river flood the land;In the Netherlands, they have broken dykes and let the sea flood the old courses of the rivers
答案:Europe
原文定位:Recently, winter floods on the rivers of central Europe have been among the worst for 600 to 700 years, and dams and dykes (protective sea walls) have failed to solve the problem
答案:Mississippi
原文定位:The same thing has happened in the US on the Mississippi river, which drains the world’s second largest river catchment into the Gulf of Mexico. Despite some $7 billion spent over the last century on levees (embankments) the situation is growing worse
答案:London
原文定位:To help keep London's feet dry, the UK Environment Agency is reflooding 10 square kilometres of the ancient flood plain of the River Thames outside Oxford
答案:soft engineers
原文定位:A new breed of ‘soft engineers’ wants cities to porous, Berlin is one place where this is being done
答案:Los Angeles
原文定位:Could this be expanded to protect a whole city? The test case could Los Angeles
