分析 作者在本文中介绍了美国北部以及加拿大流行的一种运动方式--冰下捕鱼．人们一整年就等着河里的水结冰，他们在冰面上开着卡车和摩托雪橇，把冰面打开一个洞，扔下诱饵，等着鱼上钩，这根平时的常规钓鱼没什么区别，只是时间是在冬天．钓鱼的人穿着厚厚的大衣戴着手套来取暖，有点甚至在冰洞周围建起一个窝棚来御寒．
解答 61．freezing；考查形容词，这里用形容词做表语，与前面的系动词 is 构成系表结构．
62．for；考查介词，wait for是固定短语，意为"等待"．
63．works；考查动词的时态，本文讲述一个事实，故用一般现在时，主语为it，所以用动词的第三人称单数形式．
64．waiting；考查分词作状语，句子的主语 fishers 与动词wait存在逻辑上的主谓关系，所以这里用现在分词形式作伴随状语．
65．is done；考查动词的语态，分析句子可知，主语it指代的是前面的fishing，与动词do是被动关系，故用被动语态 is done．
66．to stay；考查动词不定式，分析句子可知这里用不定式表示目的．
67．the；考查定冠词，这里用定冠词the表示特指，特指前文提到的hole．
68．easily；考查副词，这里用副词作状语，修饰前面的动词 come and go．
69．protection；考查名词，分析句子结构可知，此处要用名词形式作动词 provide的宾语．
70．who/that；考查关代词，分析句子结构可知这是一个定语从句，先行词those指代文中提到的fishermen，故关系代词用who/that．
