Three ways of expressing the same idea

December 16, 2011pdf

In many sentences you will find an agent (the person or thing who does something) and a recipient (the person or thing that something is done to). If we want to make the agent the subject, we use active verb forms.

  • The storm damaged our roof.
  • The children have stuck chewing gum all over the carpet.
  • Somebody has picked my pocket.
  • The dog bit the boy.

If we want to make the recipient the subject, we use passive verb forms.

  • Our roof was damaged in the storm.
  • Chewing gum has been stuck all over the carpet by the children.
  • My pocket has been picked (by somebody).
  • The boy was bitten by the dog.

If we want to make something else the subject, we usually use a structure with have + object + past participle.

  • We had our roof damaged in the storm.
  • The carpet has had chewing gum stuck all over it by the children.

We can usually decide what the subject should be by choosing the right verb.

Compare:

  • The retail chain employs over a million people. (Subject – the retail chain; verb – employs)
  • Over a million people work for the retail chain. (Subject – over a million people; verb – work)
