问题     An award-winning subterranean skyscraper was recently completed at the University of Minnesota. Designed by David Bennett, the building plunges 110 feet beneath the campus, peeking above the surface a mere 20 feet.
    You might think it would be dreary inside the building. But a large percentage of the usable space has access to natural light. A" telewindow "on the roof projects a view of the street via a series of lenses and mirrors. In addition,an array of reflective lenses mounted on a panel on the roof beams sunlight 60 feet down.
    " Traditional cities have too much aboveground construction, " says David Bennett. " Green space is lost and the view is disturbed. Future cities will probably be more subterranean than they are today. "
    Why build down instead up? Energy conservation is one. reason. Says Bennett, "Minnesota’s climate varies by a hundred and thirty degrees Fahrenheit, but twenty-five feet underground, the temperature remains at about fifty degrees all year round. " Subterranean construction also permits more visually pleasing land use — for instance, the preservation of an unobstructed view of historic landmark.
Another advantage in building down rather than up is that______.
选项 A、surface constructions then can be more aesthetically planned
B、historic landmarks then can be better preserved
C、there won’t be skyscrapers blocking our view
D、there will be more green land left untouched
答案B
解析 从文章的最后一句话可以分析出答案。故正确的答案为B。
