Not having got any answer,he was rather worried.这句为什么用having?

非谓语动词作伴随状态，主动词是后面的was(rather worried)，Not having got any answer是补充说明主动词的状态、原因或更进一步的说明等。可以改成两个句子：He hasn't got any answer yet,so he was rather worried.

he 是这个句子中的主语，从语法角度说 have done是一个现在完成时态，但是由于was worried 与 got any answer 的主语一致，表示主动，所以用having

前面半句是做条件状语从句用的，所以用非谓语动词
