Having been told many times,he still didn’t know how to do it.为什么不是hasing been told

问题描述:

Having been told many times,he still didn’t know how to do it.为什么不是hasing been told

having 是动词have的现在分词.而且用来做状语.用的是完成时,所以没有!

这里的ing是用来作状语的,强调程度的加深,而动词的ing形式是没有单复数之分的

having 是动词have的现在分词,has是动词have的第三人称单数,因此没有hasing这个词.
