Question Tag : You Bring Me Love, Don't You??

'Question Tag' is a special construction in English. It is a statement followed by a mini-question. The whole sentence is a "tag question", and the mini-question at the end is called a "question tag".
We use tag questions at the end of statements to ask for confirmation. Likes "Am I right?" or something proper.  They are very common in English.
This is the basic structure of 'Question Tag' :
-positive statement, negative tag?-
example : "You bring a lot of flower for me, don't you?"

-negative statement, positive tag?-
 example : "You don't pick this memo, do you?"

It's easy, isn't it? (OOPS! This is one of example 'bout 'Question Tag' ^^)

What?! OH,   you asked me to write the formula, don't you?
Okay okay,,, calm down! ^^v

FORMULA

for positive tag question

subject + auxiliary + main verb, auxiliary + not +  personal pronoun (subject)

example : You should pay your bill, shouldn't you?

               You bring a flower, don't you? ('cause it's same with "'you {do} bring a flower")

for negative tag question

subject + auxiliary + not + main verb, auxiliary + personal pronoun (subject)

example : You didn't bring you homework, do you?

             Mom shouldn't scold to Mary, should she?

It's easy, right? but... WAIT!!! There's some special cases that you should learn!
What is that?
This is for you all!! :)

I am right, aren't I? {not amn't I}
You have to go, don't you? {you (do) have to go...}
I have been answering, haven't I? {use first auxiliary}
Nothing came in the post, did it? {treat statements with nothing, nobody etc like negative statements}
Let's go, shall we? {let's = let us}
He'd better do it, hadn't he? {he had better (no auxiliary)}

and this is some mixed statement XD

But you don't really love her, do you?
This will work, won't it?
Well, I couldn't help it, could I?
But you'll tell me if she calls, won't you?
We'd never have known, would we?
The weather's bad, isn't it?
You won't be late, will you?
Nobody knows, do they?

Notice that we often use tag questions to ask for information or help, starting with a negative statement. This is quite a friendly/polite way of making a request. For example, instead of saying "Where is the police station?" (not very polite), or "Do you know where the police station is?" (slightly more polite), we could say: "You wouldn't know where the police station is, would you?" Here are some more examples:

You don't know of any good jobs, do you?
You couldn't help me with my homework, could you?
You haven't got $10 to lend me, have you?

wait! I must to go home RIGHT NOW!!!
so sorry, but I'll continue it as soon as I can.. ^^v
accept my apologize, and.... see ya! :))
