In English, question tags are short questions tagged onto the end of a statement. They are used to confirm information or ask for agreement from the listener. The structure of question tags is generally:
Positive statement + negative tag and
Negative statement + positive tag.
Below is how to fill the gaps with the appropriate tags:
She can go, can't she?
They are coming, aren't they?
She likes me, doesn't she?
We have not escaped, have we?
He has not come, has he?
They have done it, haven't they?
They have not done it, have they?
They will do it, won't they?
She does not drive well, does she?
She could not have eaten, could she?
I am tall, aren't I?
I am a Christian, aren't I?
I am a Muslim, aren't I?
Mr Abubakar did it all, didn't he?
She is light in complexion, isn't she?
These tags either affirm or ask for confirmation about the statements. When the verb in the main clause is positive, we use a negative question tag, and when the verb is negative, we use a positive question tag. This structure helps in keeping English conversations flowing smoothly and can be very handy in both casual and formal communications.
