Questions 26 to 35 are based on the following passage. The ocean is heating up. That&39;s the conclusion of a new study that finds that Earth&39;s oceans now__26__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__27__ to coral bleaching ( 珊瑚白化 ) and they take up more space than cooler waters, raising sea__28__While the top of the ocean is well studied, its depths are more difficult to__29__The researchers gathered 150 years of ocean temperature data in order to get a better__30__of heat absorption from surface to seabed. They gathered together temperature readings collected by everything from a 19th century__31__of British naval ships to modem automated ocean probes. The extensive data sources,__32__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__33__ About 35 percent of the heat taken in by the oceans during the industrial era now resides at a__34__of more than 700 meters, the researchers found. They say they&39;re__35__whether the deep-sea warming canceled out warming at the sea&39;s surface. A. absorb B. Combined C.
