(No se puede negar dos veces una oración)
3. ALREADY = YA / Affirmative Sentences

Questions:
Have – Has + subject + verb past participle + complement + YET?
Have you done your homework yet? = ¿Ya has hecho tus tareas?
Sólo use ever (alguna vez) O yet (ya) en “Yes/No Questions”.
Al usarlas wh-question a pesar que la estructura gramatical está correcta, la pregunta
empieza carecer de sentido.
