we use "the passive" to describe a process when it's not important to know who did the action.

ex. we wereall invinted to the concert...

.we form the passive like this :object+be+past participle+agent(by+noun

ex.penicillin(o)wasdiscovered(pp)by a. fleming.

NOTE:

the form the auxiliary 'be'in the passive voice is the same as the form of the verb in the active voice.

(ex. a.fleming discovered penicillin.(past simple

ex.(penicillin was discovered by A.fleming(past simple
