Grammar — The passive: The form

  • The passive is made with a form of be and a past participle.

Grammar — The passive: The agent

  • We often use the passive to draw special attention to the agent by moving it to the end of the sentence. If we mention the agent, we use by.
  • Active: A British coffee company created ‘Fresh Brew’. (attention on Fresh Brew)
  • Passive: ‘Fresh Brew’ was created by a British coffee company. (attention on the company)
  • In the above example, we mention the agent (a British company) because it is new and important information.
  • We don’t mention the agent if it is:
  • obvious: A transmitter is worn on the body. (We know it is worn by a person.)
  • unknown: Maher realised he had been followed. (We do not know who followed him.)
  • unimportant: It will be shown at the ‘New Inventors’ show. (Who will show it is not important.)
  • Present Simple: A transmitter is worn on the body and digital messages are sent via the body’s electrical field.
  • Present Continuous: The invention is being welcomed by coffee-lovers everywhere.
  • Past Simple: ‘Fresh Brew’ was created by British coffee company ‘Beans R Us’.
  • Past Continuous: When we last heard, the ‘mirror’ was still being developed in a lab in France.
  • Present Perfect: Once a profile of your lifestyle has been built up …
  • Past Perfect: When Aisha realised she had been followed to her front door, she quickly phoned the police.
  • Modal verbs in passive: It can be switched on by text message. Music and games could be downloaded in seconds. It should not be used as protection from wild animals.
  • going to: It is going to be shown at the ‘New Inventors’ show next month.
  • will: A computer shows how your appearance will be affected in future.
  • The passive infinitive: There’s one drawback: it needs to be filled with coffee and water first. The company expects their invention to be launched next year.
  • The passive gerund: It’s a ‘must have’ if you are worried about being attacked. Nobody likes being told about their bad habits, especially by a computer!
  • Some verbs are usually followed by the infinitive and others by a gerund form:
  • I require you to be on time.
  • I don’t fancy going out tonight.
  • When these verbs are used in the passive, the same verb patterns should be used:
  • The humans who were required to be in the self-driving car …
  • I don’t really fancy being monitored at all!

Grammar — The passive: Contexts for the passive

  • We usually avoid the passive in informal language.
  • We can use you or they to refer to people in general:
  • Look! You can switch it on by text message.
  • They expect to launch the invention next year.
  • The passive is common in newspaper reports and academic writing because it makes the style more impersonal and objective.

Grammar — The passive: The passive with two objects

  • Some verbs can have two objects, and either object can become the subject in the passive – it depends where the writer wants to put the focus:
  • It will show people the consequences of an unhealthy lifestyle.
  • People will be shown the consequences of an unhealthy lifestyle.
  • The consequences of an unhealthy lifestyle will be shown to people.
  • It gives anyone who touches it an electric shock.
  • Anyone who touches it is given an electric shock.
  • An electric shock is given to anyone who touches it.
  • Other verbs like this are: hand, offer, pay, promise, send, teach.
