79．how．考查特殊疑问句．句意为：但是，怎样用一种礼貌的方式结束一次对话？分析句子成分和特点可知，本为疑问句，而句子缺少状语，故填特殊疑问词，所以，本句为特殊疑问句．根据句意，确定填how，其意思是"怎样"．故填how．

81．minutes．考查名词复数．句意为：我真的得走了--十分钟后就是我的钢琴课．分析句子成分可知，介词in之后为状语，故填名词，组成介宾结构充当状语．根据句意，并结合句子中英语提示"in ten"，确定填minutes，它是名词minute的复数，意思是"分钟"．in ten minutes十分钟后．故填minutes．
82．again．考查副词．句意为：也许将来某个时间，我们会高兴地再交谈．分析句子成分可知，空格处为状语，故填副词．根据句意，并结合句子中英语提示"sometime in the future"，确定填again，它是副词，意思是"再一次"．故填again．

85．if．考查连词及状语从句．句意为：如果他们这样做．分析句子成分可知，逗号前后为两个句子，故需填一个连词，把它们连接起来．根据句意，前一句为假设，或条件关系，故填if，它是连词，意思是"如果"．故填if．
