问题补充：

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

---- There is no one else , is there?

A. who to turn to

B. she can turn to

C. for whom to turn

D. for her to turn

答案：

A. who to turn to

(答案→)B. she can turn to

C. for whom to turn

D. for her to turn

解析：句意：--为什么Jane总是向你求助？--她没有别人可以求助。这里用定语从句，先行词是no one else，定语从句中用turn to sb，所以排除CD，B项是省略了who/that引导的定语从句，A项应该是to turn to，选B。
