QUESTIONS

1.- YES / NO QUESTIONS:

Cuando el verbo principal es el verbo to be o bien tiene un verbo modal (have, can, would, etc.) invertimos la secuencia "sujeto - verbo" a "verbo - sujeto".
Are you ready, Vicky?   ...   Yes, nearly
May I use your phone?   ...   Yes, of course.
Nota: Si hubiese más de un verbo auxiliar, sólo el primero iría delante del sujeto

Cuando el verbo principal no es to be ni modal entonces usamos la forma auxiliar "do, does, did".
La secuencia sería: Auxiliar   -   sujeto   ---   verbo....
Does Mark play golf?
Did you like the concert?
Nota: El verbo principal pierde la terminación ed del pasado y la s de la tercera persona del singular.
Does Mark plays golf?
Did you liked the concert?

2.- WH - QUESTIONS

Wh-question son palabras pregunta. Las más usuales son:
Who, what, which, whose, where, when, why y how.
Son la primera palabra de la frase interrogativa, formándose el resto de la frase de igual manera a las yes/no questions.

How does the radio work?

3.- Wh-questions suelen ir acompañadas de sustantivos, adjetivos, etc que amplían la pregunta.

What kind of club  is it?
How often do you go out?
How long will the meeting last?
How much money did you spend?

Ojo.- Usamos how much si el sustantivo es incontable o how many si el sustantivo es contable.

4.- PREPOSICIONES EN WH-QUESTIONS

Las preposiciones que modifican la wh-question suelen ir al final de la frase o a continuacion del verbo principal.
