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
【C5】
选项
答案M
解析 名词辨析题。空格前有不定冠词a和形容词better作修饰语，因此应填入单数名词。本句句意为：研究者们收集了150年的海洋温度数据，以便更好地——从海洋表面到海床的热量吸收情况。由本段第二句可知，海洋深处的变暖很难研究，所以研究者们要收集大量数据。由此可推断，本空应填入含有“研究，了解”等意义的名词，而剩下的名词只有picture可以与get a搭配，故答案为M)。
