Rules
Here are some rules to follow:
1.QUESTION TAG = AUXILIARY + PERSONAL PRONOUN:
Tony can run really fast, can’t he?
The twins are very nice, aren’t they?
2.If there is no auxiliary in the statement, use a form of do in the question tag:
Mum cooks fantastic meals, doesn’t she?
3. Positive statements => Negative question tags;
Negative statements => Positive question tags:
That’s your workbook, isn’t it?
That’s not true, is it?
They will help us, won’t they?
4. Orders and commands are followed by “will you”:
Don’t open the windows, will you?
Help your dad in the garage, will you?
5. Let’s is followed by “shall we”:
Let’s start homework now, shall we?
Let’s go shopping, shall we?
6. AND DON’T FORGET :
The question tag “am I not” is totally incorrect; always say: “aren’t I”:
I am late, aren’t I?
The statements and the question tags take the same tenses:
Bob helped you a lot, didn’t he?
You will help me tomorrow, won’t you?
