Answer 1

分析 本文是一段对话，是凯特博士和鲍勃之间关于收音机用途的一段对话．自从我们还年轻的时候，收音机已经改变了很多，它曾经是家庭娱乐的主要来源．现在当你打开收音机，你或者听音乐、脱口秀或者新闻．

解答 61．has changed 考查现在完成时．根据since we were young，可知这里用现在完成时．故填 has changed．
62．to 考查固定搭配．used to do sth是固定用法，意为"过去常常做某事"．故填to．
 63．or 考查连词．根据句意"现在当你打开收音机，你或者听音乐、脱口秀或者新闻"，可知此处表示选择关系，故填or．
 64．Fortunately 考查副词．位于句首，有逗号隔开，修饰整个句子的应用副词，故填Fortunately．
65．listening考查非谓语．enjoy后的动词应用动名词形式，enjoy doing是固定用法，意为"喜欢做某事"．故填listening．
66．who 考查定语从句．根据空后的have可知，此处做主语指代先行词those，所以是定语从句，因先行词是those，故填who．
67．while/when 考查状语从句．句意：看起来人们只在开车的时候，才会听收音机．故用while/when．
 68．at 考查介词．固定短语at home意为"在家"．故填at．
69．playing 考查非谓语．have sth．doing是固定用法，sth．与动词是主动关系，意为"使某物一直做某事"．此处表示"让收音机一直开着"，故填playing．
70．communication考查名词．根据句子结构可知，此处为of形式的名词所有格，所以介词 of之后用名词形式，故填communication．
