🔼TAG QUESTIONS🔽

_____________________________________________

The tag questions are small sentences or questions (mini-questions) that are placed at the end of an affirmative or negative sentence and that are generally intended to confirm or deny the content of the sentence itself.

Tag questions (or question tags) turn a statement into a question. They are often used for checking information that we think we know is true.

Tag questions are made using an auxiliary verb (for example: be or have) and a subject pronoun (for example: I, you, she). Negative question tags are usually contracted: It's warm today, isn't it (not 'is it not').

➽ Grammatical Rules.

TRES REGLAS BASICAS QUE DEBES RECORDAR
1.	Los tag questions utilizan siempre los verbos auxiliares.
2.	Con oraciones afirmativas utilizamos un tag question en NEGATIVO.
3.	Con oraciones negativas utilizamos un tag question en AFIRMATIVO.

➔ You speak Spanish, don't you?
(Con esta pregunta indico que pienso que hablas español pero quiero confirmar que es asi.)

To form a "tag question" you start with the sentence that you think is true ("You speak Spanish" in the example above). The "tag" (the part of the sentence that makes it a question) is formed using an auxiliary verb in the negative if the sentence was affirmative or an auxiliary verb in the affirmative if the sentence was negative. See the examples in the table below.

Oraciones Afirmativas  (El verbo auxiliar en el "tag" es negativo.)	Oraciones Negativas  (El verbo auxiliar en el "tag" es afirmativo.)
To be
You're a teacher, aren't you?	You aren't a teacher, are you?

🔼MODALS OF DEDUCTION🔽

 (MUST,CAN´T,MIGHT/MAY/COULD)

__________________________

Modal verbs must, can't, might / may / could be used to express certainty, probability or impossibility

We use modal verbs to say how sure we are about something.

Modal of deduction:	Se usa cuando:
Must	Se tiene seguridad de que lo dicho es cierto.
Might, May, Could	No se sabe en realidad si lo dicho es cierto  (Pero es posible).
Can’t	Se está casi seguro de que lo dicho NO es posible.

➽ Must.

We use must when we feel sure that something is true because there’s very strong evidence.

• He must live near here because he comes to work on foot. We don’t know where he lives but we’re sure it’s not far away.
• Come inside and get warm – you must be freezing out there.
• You’re a zookeeper? That must be very interesting.

Notice that must is followed by an infinitive without ‘to’.

➽ Might, May, Could

We use might, may or could to say that we think something is possible but we’re not sure.

• Did you hear that? I think there might be a burglar downstairs. She’s not sure there’s a burglar but she thinks it’s possible.
• We’ll try to get there early but we may arrive late if there’s a lot of traffic.
• Don’t put it up there. It could fall off and hit someone.

Might, may and could are also followed by an infinitive without ‘to’.

➽ Can’t

We use can’t when we feel sure something is not true.

• It can’t be a burglar. All the doors and windows are locked. He doesn’t know it’s not a burglar but he feels sure it’s not.
• It can’t be far away now. We’ve been driving for hours. Where’s the map?
• Really? He has to work on Christmas Day? He can’t feel very happy about that.

Like the other verbs, can’t is followed by an infinitive without ‘to’.
