1. 选择：A.being rude
解析：
本句的意思是打呵欠时不掩住自己的嘴被认为是没有礼貌的。
1）it is considered being rude not to cover your mouth when you yawn 中——
真正的主语是动名词短语 being rude not to cover your mouth when you yawn，由于主语部分太长，放在谓语部分 is considered 前，即为：
——Being rude not to cover your mouth when you yawn is considered.
显而易见，这样安排显得头重脚轻。为了平衡这种凝重的结构，就把主语部分移到句尾，原主语空出的位置由形式主语 it“垂帘听政”。
2）Being rude not to cover 是“be + 表语形容词 + 不定式”这中结构，如——
* I'm glad to meet you. 见到你很高兴。
* I'm sorry not to tell you all about it. 很遗憾没有把所有的事情都告诉你（或者没有把所有的事情都告诉你很遗憾）。
此处的意思是“不掩住自己的嘴没有礼貌”。
2. 选择：A.playing
解析：
本句的意思是“你是否告诉过在那里玩耍着的孩子们不要吵闹？”
1、在 Did you tell the children playing there not to make any noise 一句中，其具体结构如下——
* 主体结构： Did you tell the children not to make any noise （用的是 tell sb. not to do sth.）
* playing there 是现在分词短语作 children 的后置定语，即“正在那里玩耍的孩子们”。
2、不定式 to play there 也可以作后置定语，不过意思与分词不同，表示的是“要在那里玩耍的孩子们”，但是 B 项的 play 前没有 to，因此不能选用。
