Una question tag convierte una afirmación en una comprobación y refleja la frase a la que va enganchada.
Recuerda
- Una afirmación positiva lleva tag negativa, y una negativa lleva positiva: you're coming, aren't you.
- La tag reutiliza el auxiliar de la frase, o toma do cuando no hay ninguno.
- El pronombre de la tag coincide con el sujeto de la frase.
Ejemplos
- 1You have lived in this coastal city for several years, haven't you?
- 2David works as an electrical engineer at the local power plant, doesn't he?

La regla
Checking and inviting agreement
Question tags are brief grammatical questions attached to the end of a declarative statement in conversational English. They are used to confirm whether something is true, or to invite agreement and keep a dialogue flowing smoothly.
Opposite polarity
The Polarity Rule: Standard question tags operate on opposite polarity:
(1) Positive Statement → Negative Tag:
- You are from Canada, aren't you?
- David works in finance, doesn't he?
- They have lived here long, haven't they?
(2) Negative Statement → Positive Tag:
- You aren't tired, are you?
- She doesn't eat seafood, does she?
- We haven't met before, have we?
Which helper to use
Auxiliary Verb Matching:
(1) When the statement contains an auxiliary or modal verb (be, have, will, can, should, must), repeat that exact auxiliary in the tag with opposite polarity:
- Emma can drive, can't she?
- The train will arrive on time, won't it?
(2) When the statement uses a lexical verb in the Present Simple or Past Simple without an auxiliary, borrow the appropriate form of DO (do, does, did):
- You like spicy food, don't you?
- Sophia works at a pharmacy, doesn't she?
- They attended the concert last night, didn't they?
A pronoun in the tag
Pronoun Rule: The subject of the tag must always be a personal pronoun matching the subject of the statement:
- The children are asleep, aren't they?

How to read this B1 topic
At B1, grammar links ideas: condition, result, reported meaning, experience, and narrative order.
1. Name the relationship
Ask whether the sentence gives a condition, contrast, cause, report, or result.
If it rains, we will stay home.
2. Separate time from aspect
Finished event, visible result, duration, and background action use different forms.
I had left before she arrived.
3. Test both clauses
In complex sentences, the second half often proves the first half.
I wish I knew.
Decision path before answering
Use these checks before choosing between close options.
- 1Mark the subject, main verb, object, and any connector.
- 2Underline the time expression or discourse clue.
- 3Reject any option with the wrong agreement, tense, article, pronoun case, or word order.
- 4Read the whole sentence once more for naturalness and register.
Contrasts that often decide the answer
Event or background
Simple forms move events forward; continuous forms show an action in progress.
I left while she was talking.
Fact or stance
Modals, hedges, and reporting structures show how certain or responsible the speaker sounds.
This may indicate a problem.
Clause or compressed phrase
Advanced writing often compresses full clauses into participle, noun, or prepositional phrases.
Having reviewed the data, we revised the plan.

Excepciones
Three Idiomatic Question Tag Exceptions: (1) I am takes the negative tag aren't I: "I am right, aren't I?" (never "amn't I" or "am not I"). (2) Imperative commands take will you or would you for polite requests: "Please close the front door, will you?". (3) Suggestions with Let's take the tag shall we: "Let's take a fifteen-minute coffee break, shall we?". Statements with Negative Words: Sentences containing negative words like never, rarely, seldom, hardly, or nobody count as negative statements and take a positive tag: "He never drinks coffee, does he?", "Nobody called, did they?".
