问题 The ocean is heating up. That’s the conclusion of a new study that finds that Earth’s oceans now【C1】______ heat at twice the rate they did 18 years ago. Around half of ocean heat intake since 1865 has taken place since 1997, researchers report online in Nature Climate Change.
Warming waters are known to【C2】______ to coral bleaching(珊瑚白化)and they take up more space than cooler waters, raising sea【C3】______ . While the top of the ocean is well studied, its depths are more difficult to【C4】______ . The researchers gathered 150 years of ocean temperature data in order to get a better【C5】______ of heat absorption from surface to seabed. They gathered together temperature readings collected by everything from a 19th century【C6】______ of British naval ships to modern automated ocean probes. The extensive data sources,【C7】______ with computer simulations(计算机模拟), created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel【C8】______ .
About 35 percent of the heat taken in by the oceans during the industrial era now resides at a【C9】______ of more than 700 meters, the researchers found. They say they’re【C10】______ whether the deep-sea warming canceled out warming at the sea’s surface.
A)absorb I)heights
B)combined J)indifferent
C)contribute K)levels
D)depth L)mixed
E)emissions M)picture
F)excursion N)unsure
G)explore O)voyage
H)floor [br] 【C10】

选项

答案 N

解析形容词辨析题。空格在系动词are之后作表语，因此应填入形容词。本句句意为：他们说他们——深海变暖是否抵消了海洋表面变暖。因为表语从句由whether引导，可以推断研究者们对深海变暖是否抵消海洋表面变暖并不确定，故答案为N)。
