Passive Voice

Passive Voice - strona bierna
Stronę bierną tworzy się poprzez odmianę czasownika TO BE w tym samym
czasie co zdanie wyjściowe w stronie czynnej oraz dodanie past participle,
czyli czasownika w 3 formie.

Zastosowanie

Przykład 1:
They did it - Past Simple - Active Voice
It was done - wciąż jest to Past Simple [was], 'it' stało się podmiotem
zdania, czasownik w 3 formie to DO - DONE, w zdaniu Active występował w
formie drugiej - did
Przykład 2:
People have seen lots of wolves in the streets - Present Perfect
Lots of wolves have been seen in the streets - strona bierna, czas
Present Perfect
Podobnie wygląda to z użyciem czasowników modalnych:

A: You must do it
P: It must be done
A: You should heve told them
P: They should have been told
Czas Continuous:
A: They are watching the movie
P: The movie is being watched - by zachować czas Continuous, musimy
czasownik To BE dać w tym samym czasie co z zdaniu Active, czyli BE +
czasownik w formie ING
A: They are building two houses

P: Two houses are being built
