Question

who, what, which在宾语从句中可做主语吗？如可以，请举例说明。

Answer 1

　　who, what, which在宾语从句中可做主语。例句如下：
　　1）I‘d like to know who is speaking English over there.
　　2）I wonder what happened just now.
　　3）I‘d like to knowWhich is the way to the school?
　　宾语从句是名词性从句的一种。在主从复合句中充当宾语，位于及物动词、介词或复合谓语之后的从句称为宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。宾语：指一个动作（动词）的接受者，常置于动词之后，也有双宾语结构例句：he gave me a book，类似拥有me和book两个宾语的句子叫双宾语从句），在复合句中，由一个句子充当宾语，这个句子就叫做宾语从句。

Answer 2

who可以作主语I would like want to know who is your teacher.
which一般是做定语较多比如Can you tell me which dog you want to buy on earth?做dog的定语
what一般不做主语而是宾语You can tell me what you want?
