Después de aprender Not Only…But Also, en está lección aprenderás To be + Past Participles.
Una forma del verbo «to be» se combina con un participio pasado para formar el pasivo. Pasivo Las construcciones verbales son útiles cuando el sujeto de una acción no es tan importante como lo que hizo el sujeto (la acción de la oración) o cuando el sujeto es desconocido. Por ejemplo, el La policía podría informar que «“The professor was assaulted in the hallways» porque no conozcen al autor de este atroz crimen. En redacción técnica, donde el proceso es más importante que quién realiza la actividad, podríamos informar que «Three liters of fluid are filtered through porous glass beads«. Independientemente del propósito del verbo, solo el auxiliar forma de cambios de «to be«; el participio permanece igual. El «to be» cambiará de forma a indicar si el sujeto es singular o plural:
- The foundation is supported by enormous floating caissons that keep it from sinking into the swamp.
- They were constructed by workers half submerged in the murky waters.
NOTE. Use this class to practice the easy forms of the passive (just to be + a past participle either in present , past or future)
