(1)陈述句：The donkey is blind in the right eye.

(2)一般疑问句：Is the donkey blind in the right eye?

(3)特殊疑问句：In which eye is the donkey blind

改为宾语从句，就是下面这个句子,tell sb +in which eye the donkey is blind

Tell me in which eye the donkey is blind. 

解答：which引导直接宾语从句，in which eye为宾语从句中状语成分。which作定语修饰名词eye, which eye作介词in宾语

句子结构为：主语+ be blind+ in right/left eye

The camel is blind in the right eye.  

那骆驼是右眼瞎了.

In which eye is the camel blind?（备注：介词in不可以省略，否则为错误表达。）

那骆驼是哪只眼瞎了？
