About tag question

[hoangkha]

Dear teachers!
- Your father says that you are going to go abroad,............?
A. doesn't he
B. aren't you
My teacher says A is correct but I don't know why B is incorrect.

Your father says that you are going abroad, doesn't he?

This is correct, since we know who says (does) it.

Compare:

You are going abroad, aren't you?

This is correct too.

Thank Mr.Bennevis!
So when a sentence has 2 clauses (or more), the subject and the verb of the first one are always used for making a tag question. Is it right?

No. It's the main clause that has the tag; that may be the second clause:

Although he's rich, he isn't happy, is he?

What about this?
- I heard you were going abroad, _______ ?
Are DIDN'T I or WEREN'T YOU correct, please?

[Barb_D]

What is the main clause? I heard [something]. So it would be "didn't I?" -- But that's a very unlikely thing to say. How would that person know what you heard?

By the way: "Is" X or Y the right choice, not "Are" X or Y the right choice.

I have seen this.
- Let me bring something to your party tonight, won't you?
I am wondering if it can be will you instead of won't you.

It's possible.

Note that in BrE the tag for let's is normally shall we?

Let's go to the beach, shall we?
