【解题导语】 本文是一篇说明文，主要介绍了世界上最大的大洋——太平洋。 61．largest 解析：考查形容词最高级。根据句意及空前的“the”可知，此处应该使用形容词的最高级形式。
62．from 解析：考查介词。此处指它从北半球的北极延伸到南半球的南极地区。from与后面的“to”形成对应。
63．surrounded 解析：考查非谓语动词。分析句子结构可知，空处在句中作伴随状语，且由空格后的“by”可知，此处指的是太平洋被围绕，表被动，故应用过去分词。
64．majority 解析：考查名词。由空前的“The”和空后的“of”可知，这里应填一个名词。major本身可以作名词，表示“专业”，显然不符合语境。此处应用majority“大部分”。
65．The 解析：考查冠词。根据water后面的修饰语“near the equator”可知，此处应用定冠词The表特指。
66．abundant 解析：考查形容词。根据语境和句子结构可知，空处在句中作定语修饰名词，故应用其形容词形式。
67．generally 解析：考查副词。此处表示通常，太平洋水域的表面循环在北半球是顺时针方向的，在南半球是逆时针方向的。应用副词修饰整个句子，故用generally。
68．which 解析：考查定语从句。分析句子结构可知，空处在句中引导非限制性定语从句，修饰先行词The exploitation，且在从句中作主语，故只能用which。
69．are harvested 解析：考查时态和语态。根据句子结构可知，pearls与harvest之间是被动关系，应用被动语态，且本文的基本时态为一般现在时，故此处也需要用一般现在时，故填are harvested。
70．mentioning 解析：考查非谓语动词。分析句子结构可知，空处在句中作worth的宾语，worth后接动词时应用其－ing形式，即用主动形式表被动含义。worth doing sth.“值得做某事”。
