网友回答
(答案→)has changed
解析：
【小题1】根据since we were young.可知这里用现在完成时。
【小题2】used to do sth是固定用法，意思是过去常常做某事 。
【小题3】句意：现在当你打开收音机，你或者听音乐、脱口秀或者新闻。所以填or。
【小题4】位于句首，有逗号隔开，修饰整个句子，故用副词形式。
【小题5】enjoy doing是固定用法，意思是喜欢做某事。
【小题6】这里含有一个定语从句，关系词在从句中作主语，指人，故用who/that。
【小题7】. 句意：看起来人们只在开车的时候，才会听收音机。故用while。
【小题8】. “在家”应该说at home。
【小题9】have sth. doing是固定用法，意思是使某物一直处于某种状态。
【小题10】of之后用名词形式，所以填munication。
