PASSIVE FORM OF VERBS
The passive form of verbs is formed of BE + the past participle,
(example : English is spoken here)
◊ We use the active form of a verb to say what a subject does.
Example : The chef cooks food every day.
◊ We use the passive form to say what happens to the subject.
Example : Food is cooked every day.
◊ The subject of a passive verb corresponds to the object of an active verb.
*Food is cooked every day. (Passive)
*The chef cooks food every day. (Active)
◊ We use the passive form of a verb when it is not important who does the action,
or when we don't know who does it.
*The letter was delivered at 9 a.m.
(The identity of the person who delivered the letter is unknown or unimportant.)
If we want to say who does the action, we use 'by' :
*The letter was delivered by the postman.
