All the exam papers _______ , the teacher sent the class home.
A. having been handed in B. having hands in C. handing in D. being handed in

A
还是过去分词作定语

因为试卷是被上交
所以用 been handed

因为试卷已经被交了
老师才让同学们回家
所以用完成时 having been done

综上所述
选A

A
All the exam papers having been handed in 做独立主格
译为：所有试卷都被交上来了，老师下课了
have been handed in 为被动语态的现在完成时形式，又因为整道题为一句话，故前半句做独立主格，所以要将have变为having

A这是独立主格用法，D肯顶不行进行时了 BC不是被动
懂了吧
