Tip # 1

How to use the Passive

The passive voice is used to show interest in the person or object that experiences an action rather than the person or object that performs the action.

The passive is used when:
We are interested in the passive, not who uses it.
  •  The house was built in 1654
We are interested in the house, not the builder.
  • The road is being repaired

We are interested in the road, not the people repairing it.

In other words, the most important thing or person becomes the subject of the sentence.

Sometimes we use the passive voice because we don't know or cannot express who or what performed the action:

  •  I noticed that a window had been left open.  
  • Every year people are killed on our roads.

If we want to say who or what performs the action, we use the preposition by:

  •   "A Hard Day's Night" was written by the Beatles.
  •   ET was directed by Spielberg.


The passive voice is often used in formal or scientific texts:  


  • A great deal of meaning is conveyed by a few well-chosen words. 
  • Our planet is wrapped in a mass of gases.
  • Waste materials are disposed of in a variety of ways.

The passive is a favourite grammar area to use for quizzes. In coursebooks, these are often 'general knowledge quizzes'. A variation on this would be to design a 'themed' quiz. For example:
Entertainment Quiz: Books, Movies, Music and Art
a)   Who was … written by?
b)   Who was …directed by?
c)   Which film was awarded the Oscar for best picture in…?
d)   Who was… played by in the movie…?
e)   Who was … composed by?
f)    Who was … sung by?
g)   Who was … painted by?
h)   This will generate lots of examples of the past passive.
i)     Geography Quiz or History Quiz
j)    Where is…grown/cultivated/harvested?
k)   What country is surrounded by…?
l)     Where is … made?
m) Who was … discovered by?
n)   In which country was … invented?
o)   When was … invented?

A geography quiz will generate lots of examples of the present passive, while the history quiz will generate examples of the past passive.

The natural follow-up to any quiz like those above would be to ask the students to make a quiz themselves.
