The passive voice 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.→Over20 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 Brunswick in 1987.→The Flight To Brunswick was written in 1987 by Tim Wilson. Only verbs that take an object can be used in the passive. The present progressive passive voice is formed: is/are/am +being done.
