Concept

Concept: To change an active sentence into the passive voice, keep the tense unchanged. The object of the active sentence becomes the subject, the verb takes the form be + past participle (V3), and the original subject (the agent) is moved into a 'by ...' phrase or dropped. The form of 'be' must carry the same tense as the original verb.

Tense rule used here: the active verb 'are providing' is in the present continuous. The present continuous passive is formed as is/are + being + past participle.

Applying it here

1. Identify the active structure: subject 'They' + verb 'are providing' (present continuous) + object 'shelter' + recipient 'to the homeless'.

2. Make the recipient the new subject: 'The homeless'.

3. Convert the verb to present continuous passive: are + being + provided.

4. Carry the remaining object across and drop the agent: 'The homeless are being provided shelter (by them).'

Contrast with the other forms

• 'are being provided shelter' keeps the present continuous tense intact, so it preserves the ongoing meaning of the active sentence.

• 'are been provided shelter' is not a valid verb form: after 'are' the continuous passive needs 'being', not 'been'.

• 'will be provided shelter' shifts the tense to the future simple passive, so it no longer describes an action happening now.

• 'have been provided shelter' is the present perfect passive, which signals a completed action rather than one in progress.
