Indirect quetions :D

We use indirect questions to ask something politely. We can do it in diferent ways:

With a final question mark

C an/colud+ you+ verb+ (complements)+?

Do+ you+ verb+ (complements)+?

Do you know...?

Do you think you could tell me...?

Without a final question mark

I wo nder if you could tell/let me...

I wonder if you know...

I woul like to know...
