借OG10-146 请教关于with/without的用法

146. A patient accusing a doctor of malpractice will find it difficult to prove damage if there is a lack of some other
doctor to testify about proper medical procedures.
(A) if there is a lack of some other doctor to testify
(B) unless there will be another doctor to testify
(C) without another doctor's testimony
(D) should there be no testimony from some other doctor
(E) lacking another doctor to testify

答案选C,没有问题.

在此,我想请教的是,with/without+n.phrase应该修饰的是从句的主语it,是否在某些情况下可以直接修饰主句的主语?是否没有定论,而需要根据句子的逻辑意思来判断?

请NN指点,最好能引用语法书上的解释.

谢谢!

能不能告诉我为什么用without先,without 后面应该是紧跟sth或者是doing sth的,without+代词+sth 应该是不对的吧,像without their doing就是错的

想请教众高手啊...感激涕凌...

有人帮忙吗?
