---Why does she always ask you for help?

---There is no one else____, is there? (2005 北京卷)

A. who to turn to B. she can turn to

C. for whom to turn to D. for her to turn

A:“因为turn to sb for help 是一个固定短语 因此 用于定语从句介词 to 不能提前”这句话对吗？

想知道A为什么错了。
顺便把句子还原一下。 感激！！谢谢啊。！
1.It is the third time ______you have made the same mistake.

帮着还原一下吧。谢谢咯、

B

否

这是一个定语从句，There is no one else （whom/that）she can turn to （for help）, is there?whom/that在定语从句中做宾语是可以省略的，其余选项句子结构不完整，故不对。 这里to也也可以提前，但是选项里面没有就不讲了。
补充问题中有序数词third，故只能填that，句子为强调句，还原为普通句子：you have made the same mistake the third time .

1.to 可以提前，There is no one else to whom he can turn for help.=he can turn to no one else for help.
2.It is +序数词+that sb.have done / It was+序数词+that sb.had done 是个固定句型“某人第几次……”

A选项错误的原因如下：
若此处who引导定语从句，定语从句必须满足三大要素：先行词，关系词，从句。若no one else 做先行词，则who做关系代词，那么who后的 to turn to 无法构成从句。所以错。
若要选A选项，则主干部分应该为I don't know who to turn to.
一家之言，希望有所帮助。
