  3. 3. Present continuous passive The air is being polluted by fumes from cars and trucks City streets are being damaged as a result of heavy traffic Present perfect passive The roadways have been jammed because of people’s dependence on cars Many parks have been lost through overbuilding The homeless have been displaced due to overcrowding in city shelters Passive with prepositions
  4. 4. Forms of passive Radio London sacked Mark Walsh is an active sentence Mark Walsh was sacked by Radio London is a passive sentence The object of the active sentence becomes the subject of the passive sentence. We form the passive with the verb be (is, was, has been, etc) + a past participle (heard, stopped, etc) The tense of the verb be changes to form the different tenses in the passive. Present simple: The show is listened to by 1 million people Present continuous: A letter is being sent to Mrs. Hind Past simple: The argument was heard by the director Present perfect: Mr. Walsh has not been offered his job back Past continuous: I was being insulted by a silly woman Past perfect: He had been given the job a month ago Future: A new DJ will be chosen soon
