非谓语 定语从句
She has no idea ( )
A to turn to whom B whom should he turn to C who to turn to D who should he turn to
不是 sb have an idea of sth/doing sb have an idea of wh~sb have an idea that~
答
应该是C
她不知道要向谁寻求帮助。
这是个倒装句
举个句式相仿的例子 e.g.she has no idea what to do.
本题同理。
答
1.have no idea其实等于“don't know”,在此意上C（who to turn to）可理解为宾语从句.
2.若将C（who to turn to）看做“idea”的同位语从句也可,补充说明了"idea"的内容.
