1、___in a friendiy way , their quarrel came to an end.
A being settled
B having settled
C settled
答案选C,AB为社么不可以呢什么时候可以用B
答：settle是个及物动词,如settle the problem. 意为解决问题. settle their quarrel 是动宾关系.反过来,their quarrel was settled down 就是主谓被动关系了.
C.= As their quarrel was settled in a friendly way, their quarrel came to an end.
但这样说很啰嗦,所以简化成C.B是主动,宾语呢?
汉语翻译也要简洁：他们的争吵（被）（用一种）友好的（方式）解决了,终于结束.
注意：分词作状语时,其逻辑主语就是主句的主语.根据它和这个动词之间的关系决定用主动式还是被动式.their quarrel 与settle显然是被动关系,所以先要排除的就是B!
但A也是被动关系,你清楚为什么不用A了吗? Being settled是什么意思呢?它和having been settled, settled有什么区别呢?为什么这里没有having been settled 这个选项呢?如果有,可以吗?这就是深层次的问题了!
当主语是They的时候,后面有宾语时：
Having settled their quarrel in a friendly way, they were both happy.
2、he must be angry,for we heard the glass ____on the floor
A being broken
B broken
答案选A为什么
答：hear sth. being done听到某事正在被做.
being broken是个正在进行的被动动作,这里表示：我们听到了有人（就是他啦）正在将那杯子住下扔.其实用glasses更好.因为扔一个杯子的时间是很短的,等你作出那个判断时,扔一个杯子的动作早就结束了.但几个杯子一个一个地扔,是可以一直进行下去的,A相当于：for we heard him breaking the glasses. 不能再细究了,此题为出题而造,问题很多:如：这里讲的是过去的事情吧,则主句应为：He must have been angry, for ...
如果主句不变,为He must be angry, 则讲的是现在的情况,则for后面的这个句子应为现在时态：for we hear the glasses being broken. 这个on the floor也是多余!
而broken是过去分词,说sth. is broken时,是状态,不是动作.所以heard the glass broken是不合生话逻辑的,你只能see the glass broken, 不能heard it broken回复

都是被动语态的用法
