Active and Passive Voices

The active voice is a sentence structure where the subject performs the action of the verb. For example, 'The cat chased the mouse.'

The passive voice is a sentence structure where the subject receives the action of the verb. For example, 'The mouse was chased by the cat.'

In the present simple tense, the passive voice is formed using 'is/are' + past participle. For example, 'The book is read by the students.'

In the past simple tense, the passive voice is formed using 'was/were' + past participle. For example, 'The letter was written by Tom.'

A past participle is a verb form used in passive voice and perfect tenses, often ending in -ed for regular verbs. For example, 'played' in 'The game was played.'

'Was told' indicates a completed action in the past, while 'has been told' indicates an action that has relevance to the present.

An example of an active voice sentence is 'The teacher explains the lesson.'

An example of a passive voice sentence is 'The lesson is explained by the teacher.'

Use the passive voice when the doer of the action is unknown, unimportant, or when you want to emphasize the action itself.

A passive voice sentence typically follows the structure: Subject + form of 'to be' + past participle + (by + agent). For example, 'The cake was eaten (by the children).'
