-why does she always a you for help?-there's no one else ____ ,is there?A who to turn toB she can turn on C for whom to turn D for her to turn请详细解答　谢谢！ 
回答：先A。

-为什么她总是请你帮忙？
-她没有其他人可以求助，不是吗？

there's no one else who to turn to

参见以下两个网址里的歌曲:There is no one else to turn to，里面省略了一个who
the one I can turn to我可以求助的人，这里也省略了一个who
the one who I can turn to

turn to 求助于

A who to turn to /也可以是whom to turn to或to turn to
B she can turn on /应该改为she can turn to
C for whom to turn 错误
D for her to turn后面应该加to
