题目内容：

But how did she fare after her return to a war-torn nation struggling to stand on its own?
after her,为什么是after her不是after she?

优质解答

因为后面的return是个名词而不是动词.
如果要after she,要这么用：
But how did she fare after she returned to a war-torn nation...

追问：

改成过去时态能跟介词后面？什么道理？

追答：

哪里跟在介词后面？after she returned...是个从句。
