这道题目答案是A,我想问一下这里A选项的having的这个结构,记得现在完成时结构不能做定语修饰,这里是什么成份啊?谢谢大家。
就我个人理解,这里having不是拿来做定语的,如果having是定语,那么for example就没有下文了,也就是说如果是定语那么要for example干嘛?
这里having的这个结构可以被看作单纯的两个名词结构,作为for example的内容!
说它们是inadequate treatment的同位语好像也不恰当!
呵呵,只有等高手来了!
原来如此。因为 for example 的缘故,两个having...是动名词,做举例子的内容。谢谢!明白了。
谢谢
