We use passive voice instead of active voice in the following situations:
When the action is more important than the doer.
The text was written by Joshua.
When the doer of the action is unimportant or unknown.
The window was broken las night.
The robber was arrested this morning.
When we do not want to mention the doer of the action.
The second desk in the classroom is scratched.
In formal style.
I can be contacted every weekday from 9 am to 2 pm.
We form the passive voice in the following way:
Martin sends e-mails every day. (active voice)
E-mails are sent (by Martin) every day. (passive voice)
The object from the active voice sentence becomes the subject of the passive voice sentence. The verb in passive voice consists of : the verb to be in the corresponding verb tense and the past participle of the verb in the active voice sentence. if we want to introduce the doer of the action we use the preposition by.
Here are examples of passive voice sentences:
|He washes the car every week.
|The car is washed every week.

|The car is being washed now.

- The active voice sentence does not have an object.
- If the active voice sentence contains some of the following verbs: be, have, resemble, lack etc.
Note that if the active voice sentence has two objects, then we can form two passive voice sentences.
