啃PREP的时候看到了好几处写的“现在分词的完成式havingdone不做后置定语”但是又觉得这个题目违背了这个原则。

having done可以做非限定性修饰，不能做限定性修饰啊~having....在句子当中就是修饰N，符合prep讲的原则

having done在这里不是修饰主语N的，是用于修饰后面的谓语动词的，表示先于谓语动词，N已经做了。。。。。

nope

here the having done is modifying the subject neuroscientist

when u see the structure “s ，ving，vo”

you can move the ving before the subject

ving，svo

these two structures are same in meaning
