虽然林巧稚从未结婚，她却被称为“一万个孩子的妈妈”，一生中接生了5万多个孩子。
(1)句式分析：这是一个主从复合句。主句是she was known as the “mother of ten thousand babies”，前面是though引导的让步状语从句。having delivered...是动词ing形式的完成形式，在句中作状语。
(2)动词ing 形式的完成式主要表示发生在谓语动作之前的动作，常用作状语，一般不能作后置定语，但可作非限制性的后置定语。
This question, having been discussed for more than 2 years, has now been solved.
