Advanced gerund and infinitive patterns often show time, voice, or a change in meaning.
Use perfect forms to show that the action happened earlier: to have done, having done.
Use passive forms when the subject receives the action: to be informed, being criticised, having been selected.
| Use | Pattern | Example |
|---|---|---|
| Core form | Perfect infinitive | She claims to have seen the document. |
| Variation | Passive gerund | He resented being criticised publicly. |
| Advanced form | Perfect passive gerund | Having been selected, the team began training. |
Remember + -ing refers to a memory of a past action; remember + to-infinitive refers to an obligation.
Stop + -ing means end an activity; stop + to-infinitive means pause in order to do something.
