文章大意：本文主要讲的是收音机在今天的用途。
答案：
1.has changed 由时间状语since从句可知，此处用现在完成时。
2.to used to“过去常常，惯于”。
3.or 现在打开收音机，你要么听音乐、听脱口秀节目或者新闻。either...or...“或者……或者……”。
4.Fortunately 用副词修饰整个句子。
5.listening enjoy后接代词、名词或动名词。所以此处用listening。
6.who/that 一些脱口秀主持人对持异见的人非常粗鲁。先行词是those，指人，从句部分缺少主语，所以填关系代词who或者that。
7.while 好像人们只在开车的时候听音乐。while “当……的时候”符合语境。下一句话也有提示“...while he is...”。
8.at 考查固定搭配。at home“在家里”。
9.playing 很多商店让收音机一直开着。have...doing...是指让某人一直做某事或者让某事一直在进行，强调动作的持续性、连续性或者动作的反复性。
10.communication 介词of后接名词。communication“交流”。
