问题     Three key facts about rising sea levels need to be hammered home to the world’s politicians and planners: sea-level rise is now inevitable, it will happen faster than most of us thought, and it will go on for a very long time.
    Even if greenhouse gas emissions stopped tomorrow, the oceans will continue to swell as they warm, and as glaciers and ice sheets melt or slide into the sea. The climate scientists estimate that sea-level rise could well be in the region of 1 to 2 metres by 2100, with a small risk of an even greater rise.
    For many islands and low-lying regions, even small rises will spell disasters. Most countries, however, will only lose a tiny percentage of their land, even with a very big rise. The problem is what has been built on that land: New York, Sydney and Tokyo, to mention just a few cities. Unless something can be done, great areas of urban network will vanish beneath the waves. It will take a massive engineering effort to protect these cities — an effort that may be beyond economies that have been brought to their knees by climate change.
    None of this means we should despair, and stop trying to ban emissions; the more we pump into the atmosphere, the higher and faster the seas will rise. But alongside these efforts, we need to start acting now to minimise the impact of future sea-level rise. That means we must stop building in the danger zone.
    Countless billions are being spent on constructing homes, offices, factories and roads in vulnerable coastal areas. For instance, the skyscrapers of Shanghai are being built on land that is a mere 4 metres above sea level on average, and which is sinking under the weight of its buildings and as water is drawn from the rocks beneath them.
    In cities that have been around for hundreds of years, this sort of development may be understandable. But planning for new coastal developments is to fly in the face of reality. If we want to build a lasting heritage for our children, we should do so on the plentiful land that is in no danger from the sea. It is one of the easiest ways to slow down climate change, and we should be acting on it now. [br] What does "fly in the face of reality" (Line 2, Para.6) mean in the passage?
选项 A、Cater for most people.
B、Go against reality.
C、Accord with the law of nature.
D、Accept the reality.
答案 B
解析 根据题干中的fly in the face of reality将本题出处定位到末段。本段第一句提到，对那些已有数百年历史的城市来说，这样的发展是可以理解的。But表转折，提示前后意思应该是相反的，再根据下文中提到我们应该将其建在远高大海影响的富裕的土地上的提示，可以推断出，新的沿海发展规划应该是不被理解，不切合实际的，故答案为[B]。fly in the face of sth．为固定短语，意为“悍然不顾：与……相悖”。
