  The ocean is heating up. That’s the conclusion of a new study that finds that Earth’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 modern 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’re  35  whether the deep-sea warming canceled out warming at the sea’s surface.

1.[选词填空]
    • 解题思路:句意:研究人员收集了150年的海洋温度数据,以便更好地了解从表面到海床的吸热情况。分析句子结构可知,空格处应填入名词。get a better picture of表示“更好地了解……”,符合语意。故答案为M。
    2.[选词填空]
      • 解题思路:句意:地球的海洋现在吸收热量的速度是18年前的两倍。分析句子结构可知,空格处应填入动词。文章第一句提到海洋正在升温,可知此处表示吸收热量,absorb意为“吸收”,故答案为A。
      3.[选词填空]
        • 解题思路:句意:他们说,他们不确定深海变暖是否抵消了海洋表面变暖。分析句子结构可知,空格处应填入形容词。空格后面whether引导宾语从句,结合备选项可知,此处填unsure。故答案为N。
        4.[选词填空]
          • 解题思路:分析句子结构可知,空格处应填入名词。fossil fuel emissions 表示化石燃料排放,符合语意。故答案为E。
          5.[选词填空]


            • 解题思路:句意:研究人员发现,约35%的工业时代海洋吸收的热量现在存留于700多米的深处。分析句子结构可知,空格处应填入名词。由后面的more than 700 meters可知,此处指深度,at a depth of意为“在……的深度”。故答案为D。
            6.[选词填空]
              • 解题思路:句意:他们汇总了被所有事物收集的温度记录,从19世纪英国海军船只的一次航行到现代的自动化海洋探测。分析句子结构可知,空格处应填入名词。空格后面提到naval ships,结合备选项可知应填voyage。故答案为O。
              7.[选词填空]
                • 解题思路:contribute。考点:动词。句意:海水变暖会导致珊瑚白化。分析句子结构可知,空格处应填入动词原形。contribute to意为“有助于;促成;导致”,是固定短语。故答案为C。
                8.[选词填空]
                  • 解题思路:句意:广泛的数据来源,结合计算机模拟,创建了一个海洋温度变化的时间表。combine with为固定搭配,意为“结合”,符合语意。故答案为B。
                  9.[选词填空]
                    • 解题思路:句意:温水占用的空间比冷水多,会造成海平面上升。分析句子结构可知,空格处作raising的宾语,应填名词。sea levels表示“海平面”,符合语意。故答案为K。
                    10.[选词填空]
                      • 解题思路:句意:虽然海洋的表层被研究得很好,其深处却更难以探索。分析句子结构可知,空格处应填入动词原形。while表对比转折,可知此处表示难以研究。explore意为“探索,勘探”,符合语意。故答案为G。
