Questions

[SueC]

One thing that is really confusing me is how to structure questions.  I know that 'w' questions tend to go at the end of a sentence but what about other questions such as : Do you know him?  Have you seen it? 

Do you just make a statement with a quizzical look on your face or is there another way to ask these kinds of questions? 

Thanks in advance to anyone who can help

Know then point with facial. 

Have you seen it so you would have to explain what it is. For instance have you seen the beautiful flowers near my house? or  have you seen the new film "title".  It's not clear what it is, or where I might see it.
