Step 4. Structure learning: The Present progressive Passive Voice

1. Passive Voice

The passive voice is used when focusing on the person or thing 3

affected by an action.

The Passive is formed:

Passive Subject + To Be + Past Participle It is often used in business and in other areas where the object of the action is more important than those who perform the action. For Example:

We have produced over 20 different models in the past two years.→

Over 20 different models

have been produced

in the past two years.

If the agent (the performer of the action) is important, use “by”.

For Example:

Tim Wilson wrote The Flight to Brunnswick in 1987.

The Flight to Brunnswick was written in 1987 by Tim Wilson.

Only verbs that take an object can be used in the passive.

The following chart includes sentences changed from the active to the passive in the principal tenses.

Active Passive Time Reference They make Fords in Cologne. Fords are made in Cologne. Present Simple

Susan is cooking dinner. Dinner is being cooked by Susan. Present Continuous

James Joyce wrote Dubliners. Dubliners was written by James Joyces. Past Simple

They were painting the house when I arrived. The house was being painted when I arrived. Past Continuous

They have produced over 20 models in the past two years. Over 20 models have been produced in the past two years. Present Perfect

They are going to build a new factory in Portland. A new factory is going to be built in Portland. Future Intention with Going to

I will finish it tomorrow. It will be finished tomorrow. Future Simple

2. Passive Verb Formation

The passive forms of a verb are created by combining a form of the “to be done.” with the past participle of the main verb. Other helping verbs are also sometimes present: “The measure could have been killed in committee”. The passive can be used, also, in various tenses. Let’s take a look at the passive forms of “design”.

Tense Subject Auxiliary Past Participle Singular Plural Present

The car/cars is/are designed.

The car/cars has been/ have been designed.

Present perfect

Past

The car/cars was /were designed.

The car/cars had been/ had been designed.

The car/cars will be /will be designed.

The car/cars will have been /will have been Past perfect

Future

Future perfect

designed.

Present progressive

Past progressive

5

The car/cars is being /are being designed.

The car/cars was being /were being designed.

Step 5. Reading and identifying

Since you are clear about Passive Verb Formation, go back to Page 26 and scan the text for all the examples of The Present Progressive Passive Voice.

Our fur is being used to make sweaters like yours.

She was being watched by an excited elephant.

…

Now try to put the following sentences into The Present Progressive Passive Voice.

Antelope is looking at her.

They are killing us for the wool.

They are destroying the farm.

Step 6. Discovering useful structures To consolidate your learning of The Present Progressive Passive Voice, turn to Page 29 and do the grammar Exercises 1, 2 and 3, also on the very Page of 29. And play the game called “Tell me what is happening?” Ask questions containing The Present Progressive Passive Voice.
