A gerund or infinitive becomes passive when its logical subject receives the action rather than performs it. The difference lies entirely in who is doing what to whom.
Both sentences are grammatical. They describe different situations, and choosing the wrong form changes the meaning.
Passive gerund
The passive gerund is formed with being + past participle. It appears after verbs that take a gerund, whenever the subject is the receiver of the action.
Common triggers include enjoy, hate, like, love, mind, avoid, remember, deny, risk, resent, imagine.
Passive infinitive
The passive infinitive is formed with to be + past participle. It appears after verbs and adjectives that take an infinitive, whenever the subject is the receiver.
Common triggers include want, expect, hope, need, deserve, agree, refuse, and adjective patterns like nice to, lucky to, eager to.
After modal verbs, the same form appears without to: these doors should be locked at night, the report must be submitted by Monday.
Perfect passive forms
When the passive action happened before the main verb, English uses a perfect passive form. These are formal and comparatively rare, but they appear in reported speech, claims, and legal or academic writing.
Perfect passive gerund — having been + past participle:
Perfect passive infinitive — to have been + past participle:
In everyday speech, a simple passive form is usually enough. Use the perfect versions only when the time gap between the two actions is important.
Active vs passive at a glance
| FORM | ACTIVE | PASSIVE |
|---|---|---|
| Gerund | teaching | being taught |
| Infinitive | to teach | to be taught |
| Perfect gerund | having taught | having been taught |
| Perfect infinitive | to have taught | to have been taught |
The choice depends on whether the subject of the main verb is the doer or the receiver. The students enjoy being taught — the students receive the teaching. The teacher enjoys teaching — the teacher performs it.
