English sentences can be in either active or passive voice. The
difference between active and passive is the placement of the
subject and the object.

In active sentences the subject goes first. In
passive sentences the object, or the receiver of the action,
goes first.

(Active) Jeff stole the money.
(Passive) The money was stolen by Jeff.

Consider this active sentence:

The boy broke the window.

Subject: The boy
Object: The window

To make the sentence passive:

1. Switch the subject and the object
2. Add the verb To Be
3. Put the original verb in past participle

The window was broken by the boy.

When creating passive sentences from active sentences
remember the verb must have a direct object.

Bill slept until 9:00 am.

(No direct object = No passive sentence)

Bill ate breakfast at 9:30 am.

(Breakfast is the direct object)
(Breakfast was eaten by Bill.)

The verb "to be" must be in the same tense as the active
sentence.

Bill ate breakfast.

(Active, simple past)

Breakfast was eaten by Bill.

(Passive, simple past)

Bill will eat breakfast.

(Active, simple future)

Breakfast will be eaten by Bill.

(Passive, simple future)

The passive is often used in three situations:

1. The “doer” of the action is not known.

My bicycle was stolen.

(It is not known who stole the bicycle.)

2. The “doer” of the action is obvious or not important.

Spanish is spoken in Mexico.

(The subject,people, is obvious.)

3. The object is the most important part of the sentence.

The diamond was stolen by two thieves.

This list shows the active and passive sentences for all the
major verb tenses.
