问题     The fact is, the world has been finding less oil than it has been using for more than twenty years now. Not only has demand been【C1】______, but the oil we have been finding is coming from places that are【C2】______to reach. At the same time, more of this newly【C3】______oil is of the type that requires a greater investment to【C4】______. And because demand for this precious resource will grow, according to some, by over 40 percent by 2025, fueling the world’s economic【C5】______will take a lot more energy from every possible source.
    The energy industry needs to get more from existing fields while continuing to search for new【C6】______. Automakers must continue to improve fuel efficiency and perfect hybrid(混合动力的)vehicles.

Governments need to formulate energy policies that promote【C8】______and environmentally sound development. Consumers must be willing to pay for some of these solutions, while practicing conservation efforts of their own.
    Inaction is not an【C9】______. So let’s work together to balance this equation. We are taking some of the【C10】______needed to get started, but we need your help to go the rest of the way.
A)consequently I)feasible

C)declining K)option
D)derived L)refine
E)difficult M)reserves
F)discovered N)soaring
G)economically O)steps
H)exception
【C1】

选项

答案N

解析 空格所在句为not only…,but….句型,由于本句以not only开头,出现了倒装,正常语序应该为demand has been 36,由此可见,本句为主系表结构,因此空格中应该填入形容词,而第一句中讲到,目前世界上石油的勘探量已经赶不上石油的消耗量,可见石油的需求是在上升。由此确定形容词soaring为本题答案,意思为“急速上升的”。备选词语中形容词很多,但能够形容需求量变化的只有两个,declining和soaring,declining意思为“下降的,衰退中的”,与此处要表达的“上升的,增长的”意思不符合,可以排除。
