问题     John Lee likes to tinker with vehicles: his four-wheel-drive resembles a tractor more than a car. "It’s watertight," he smiles. For the past week he has been driving down sodden lanes in Surrey, southwest of London, transporting people and medicines. Flooding is a misery, but at least it provides an opportunity to show off a set of wheels.
    Much of southern England is now sodden, and parts of the Thames Valley and Somerset are simply underwater. In Shepperton, a town in Surrey, the village green used for the summer fete is best reached by canoe. In Devon a sea wall has collapsed, shutting down a vital railway link to the south-west. As The Economist went to press, 16 severe flood warnings had been issued by the Environment Agency, a much-criticised quango that oversees flood defence.
    Floods are like snowflakes, says Andrew McKenzie of the British Geological Survey, a research body: none is quite like another. Rivers can overflow, as in Somerset. Groundwater can flood, as in the Thames Valley. Tides can surge, inundating villages, as they have in Lincolnshire. Rain can pound down too quickly to be absorbed. None of these is rare on its own. But over the past two months Britain has been subject to the whole lot, often in combination, over a large area.
    Last month was the wettest January in southern England since 1910. The rain was unusually prolonged, falling on 23 days out of 31, a four-decade record. Rain continues to fall on this sodden ground. As a result, the Thames river has been running high for longer than at any point since records began in 1883. The calamitous floods that struck England in 1947, by contrast, were over much more quickly.
    Fingers have been pointed at the government, for squeezing the Environment Agency’s budget. According to the Committee on Climate Change, an independent body, government funding for flood management between 2011 and 2015 will be less than in the previous four years, even in cash terms. The maintenance budget was cut particularly savagely, says Iain Sturdy of the Somerset drainage board.
The tractor-like car is described mainly to show ______.

选项 A、severity of the flood
B、lack of transportation
C、uniqueness of wheels
D、shortage of medicines

答案A

解析 根据题干中的“tractor-like car”定位到第一段。文章开头描述了tractor-like car,讲述其用途,到最后一句指出:Flooding is a misery,but at least it provides an opportunity to show off a set of wheels.接着几个段落都在讨论洪水,可见文章开头描述tractor-like car是为了引出“洪水”的话题,即为了显示出“severity of flood(洪灾的严重性)”,故选项A为答案。
