Hi! I'm Tom and today I'm going to show you
how to use tag questions.
We use tag questions to ask for confirmation.
For example:
It's a melon, isn't it?
'Isn't it' has a similar meaning to 'do you agree'?
When the statement is positive,
we make a negative question.
And when the statement is negative,
we make a positive question.
It isn't a banana, is it?
We can use other auxiliary verbs with tag questions
and these show a change in tense and meaning.
For example:
You won't eat my melon, will you?
When there's no auxiliary verb,
we make a question using 'do'.
Elly, you really like melons, don't you?
She really does.
