The Passive Voice is very important in English language.
Only transitive verbs can form a passive.
The passive voice is used :
- When the doer of the action is unknown:
The email is send yesterday.
He was forced to go home.
I’ve been told to come.
She was taken to hospital last week.
- If the doer of the action is unimportant:
He was much loved.
She was sent overseas.
He was elected president.
- If we do not want to mention the doer of the action:
I was told not to do this.
He was told to leave office.
Beer was spilt all over the table.
- When we want to stress the doer of the action, then doer takes end position in a sentence:
He was called by mother.
The song was written by David Bowie.
The thief was punished by law.
