一个英语选择题的疑问

1.She has been in ____ doctors descirbe as a vegetative state for six years.
A.what B.which C.that D.how
这里答案选A，可是为什么不能选B呢？which不也可以作为宾语和主语吗？
which难道不能引导名词性从句吗？

Answer 1

是应该选A，which 通常引导的是定语从句，但这个句子中空格前面没有要修饰的名词，故应该用what引到一个表语从句，what在从句中作宾语。
要改成如下时可用which：
she has been in a state which doctors describe as a vegetative state for six years.她已经处于医生说的植物人状态六年了。

Answer 2

医生描述的是WHAT，比如医生说的某种药用WHICH

Answer 3

原句意为：她已成植物人有六年了。

所以原句可以简化为 she has been in a vegetative state for six years.

如果是用which,则应该是She has been in a state which doctors describe.... which 引导的句子修饰前面的名词。
