which可以引导宾语从句吗？若可以，在句中做什么成分？举例

可以引导宾语从句，在从句中作主语、宾语或标语等。如：
Can you tell me which you like best? 你能告诉我你最喜欢哪一个吗？（宾语）
Could you tell me which is yours? 你能告诉我哪个是你的吗？（主语）
Can you tell me which your father is?你能告诉我你爸爸是哪位吗？（表语）

• 可以。 如：Can you tell me which house is yours? 你能告诉我那个房子是你的吗？做的是主语又如：I don't know which company he works in.我不知道他在哪家公司工作。

• 比较少的情况，它引导名词性从句（包括宾语从句）时，表示有选择范围：I read it in a book, or on the Internet. Does it matter which it is?

• 可以，主语，宾语。I don't know which matters.I don't know which you like.

• 比较少见但是双宾语的时候可以He told me which apple is Ann‘s.
  

可以。 如：Can you tell me which house is yours? 你能告诉我那个房子是你的吗？做的是主语又如：I don't know which company he works in.我不知道他在哪家公司工作。 做的是形式主语希望会采纳，O(∩_∩)O~

可以，主语，宾语。I don't know which matters.I don't know which you like.
