阅读理解。 Three key facts about rising a levels need to be pointed out to the world's politicians and planners: a-level ri is now unavoidable (不可避免的), it will happen faster than most of us thought, and it willgo on for a very long time. Even if greenhou gas emissions (排放) stopped tomorrow, the oceans would continue to become larger as they get warm. The climate scientists estimate that a-level ri may be in the range of 1 to 2 meters by 2100, with a small risk of an even greater ri. For many islands and low-lying regions, even small ris will cau disasters. But for most countries,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 disappear under the waves. It will take a great engineering effort to protect the cities-an effort that may be beyond economies thathave been brought to their knees. None of this means we should fear, and stop trying to forbid emissions. But together with the efforts, we need to start acting now and we must stop building in danger zones. Billions of dollars are being spent on constructing homes, offices and roads in vulnerable (脆弱的) coastal areas. For instance, the skyscrapers of Shanghai are being built on land that is mere 4 meters above a level on average, and they are sinking under the weight of the buildings. Therefore, planning for new coastal developments is to go against 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 a. It is one of the effective ways to slow down climate change, and we should be acting on it now. 1. The most possible reason for the rising of a levels should be _____. A. greenhou gas emission B. temperature change of the oceans C. vulnerable coastal area D. fast urban development and expansion 2. New York, Sydney, and Tokyo are mentioned in this passage to show _____.

According to the author, we should _____ to deal with a-level ri. A. move big cities like New York and Shanghai to higher places B. stop building skyscrapers in big cities like Sydney and Tokyo C. build cities on the land free from the danger of a-level ri D. be aware of the danger of greenhou gas emissions into the ocean 题型：未知难度：其他题型
