Answer 1

答案：
61．largest     考查形容词的最高级    本句的意思是：太平洋是地球上最大的海洋；此处用在定冠词the之后，应使用形容词的最高级；故填largest
62．covering  考查现在分词    此处在句中作原因状语，动词cover与其逻辑主语构成主谓关系；故填现在分词covering
63．from       考查固定短语      固定短语from…to…"从…到…"；本句话的意思是：它从北部的北极圈一直延伸至南部的南极洲；故填from
64．majority  考查名词以及词形转换   此处用在冠词the之后在句中作主语，指大多数的岛屿；故将形容词major转换为名词majority 
65．The         考查定冠词    此处特指赤道附近的水域；故填The 
66．abundant     考查名词以及词类转换    此处用来修饰名词precipitation；意为：丰富的赤道降水；故名词abundance转换为形容词abundant
67．generally    考查副词    此处在句中修饰形容词clockwise；故填副词generally
68．which         考查关系代词    根据句意以及空缺处之前的逗号可知，本句是非限定性的定语从句；由于此处的关系代词指代的是逗号之前的句子；故填which
69．are harvested    考查时态及语态    由于此处的主语pearls与及物动词harvest构成动宾关系；根据上下文使用了一般现在时可知，此处应使用一般现在时态的被动语态are harvested   
70．mentioning    考查动名词   由于此处用在动词worth之后，意为：值得干某事；故填动名词形式mentioning
