UPPER INTERMEDIATE - GRAMMAR 1 (page 1)

PASSIVE SENTENCES

We can have passive sentences in many different tenses.
For example:

The snake was eaten.
The snake had been eaten.
The snake will be eaten.
The snake has been eaten.
The snake is being eaten.

... and so on.

In a passive sentence we are not so interested in who or what did the action (who ate the snake). We are more interested in the result.

The passive is formed by putting the object of the verb before the verb. We can move the subject of the verb to the end or we can delete it.
Example:
The man      /      ate      /      the snake.
(subject)      /     (verb)    /       (object)

The men ate the snake. (active)
The snake was eaten. (passive)
The snake was eaten by the men. (passive)

We use an auxilliary and a past participle. Click here for a list of common past participles.
