It`s wrong to put "do" as well as the question mark (?)
I mean that this kind of sentences are known as Indirect Question.
As you add an indirect clause at the beginning you do not end asking.
I mean the following:
How old are you?
I would like to know how old you are
I would like to know how old [STRIKE]are you[/STRIKE]?
This is the whole help that I can give you, since it is difficult to explain it by writing, you`d better ask a teacher. [STRIKE]Considerate[/STRIKE] Considermy advice, nice to meet you and good luck...
Hi
1. I'd like to ask which days do you see the patients?
2. I'd like to ask which days you see the patients?
--- Do I need "do" or not?
(no need to say 'I'd like to ask' - just ask!)
