[求助]og１４６

２．og１４６　 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

why in choice a ,lack of is unidiomatic??

og解释如下:

choice a also introduces the unidiomatic phrase lack of some other doctor.

(A)"there is a lack of  some other doctors" refer to the situation with no doctor

Insteas, (B) show the more logic connection with main clause.

这我知道,他重心出了错误,但og强调的是lack of unidiomatic,

if you were right,  OG should not emphasize that lack of is unidiomatic, right?

正确的搭配应该是some...some other...吧.(A的doctor是不是该用复数啊)

顺便说一下,标准书面语中there be表示自然存在.医生自然存在不大合逻辑啊

我还有个疑问. 如果E的前边加个逗号,是不是也可以,做伴随状语

应该不可以，逻辑主语有问题

不懂,逻辑主语不是和主句的一致吗,the patient.没问题呀

请指教

如果没有逗号，lacking直接修饰damage, 所以逻辑错误。如OG所说,

Choice E introduces a dangling modifier: the lacking... phrase cannot logically modify damage, the nearest noun.

如果有逗号，那么lacking可以认为是分词修饰主语。但是这里有两个问题，

1. 距离主语太远，中间有damage, 还是会造成歧义。

2. 没有lack sb to do sth这种用法。lack后面直接加sth。

见longman的解释:

1 [transitive] to not have something that you need, or not have enough of it
- Alex's real problem is that he lacks confidence.

2. not lack for something
formal, to have a lot of something
- He does not lack for critics.

那有没有lack of sb to do sth的用法呢？还是只能lack of sth /lack sth
