分析 短文主要讲了纸的各种用途．
解答 61．used，考查时态，句子描述的是过去的动作，应使用一般过去时．
62．named，考查非谓语，句子谓语动词created，name应使用非谓语形式，与其逻辑主语a Chinese man构成被动的关系，因此使用过去分词充当后置定语．
63．the，考查冠词，位于某一世纪之前应使用定冠词the．
64．as，考查固定搭配，use sth．as sth．"把…用作…"．
65．in，考查介词，表示使用…方式，应用介词in．
66．that/which，考查定语从句，句子先行词products，引导定语从句使用that/which．
67．it，考查代词，指代前文提到的toilet paper应使用代词it．
68．putting，考查动名词，of是介词，后接动词的动名词形式．
69．commonly，考查副词，此处应使用副词修饰谓语动词．
70．what，考查宾语从句，从句缺少be like的宾语，应使用"什么"的what来引导．
点评 对于语法填空这类题，一是懂得分析句子结构，二是知道充当各个句子成分的词类或词性，从语法上确定答案，当然，对于某些固定搭配也要牢记，在平时的学习中要多积累这些词汇或短语，对于句子使用的时态语态也要通过语境进行确定．
