Here's a breakdown:
How to Recognize a Past Participle:
* Regular verbs: They often form their past participles by adding "-ed" to the base form.
* Example: walk (base form) → walked (past participle)
* Irregular verbs: They have unique past participle forms that don't follow the "-ed" rule.
* Example: see (base form) → seen (past participle)
Uses of Past Participles:
1. To form the perfect tenses:
* Present perfect: "I have walked to the store."
* Past perfect: "She had seen the movie before."
* Future perfect: "They will have finished their work by tomorrow."
2. To form passive voice:
* The past participle is combined with the verb "be" to create passive voice.
* Example: "The car was driven by a teenager." (The action of driving is done to the car.)
3. As adjectives:
* Past participles can describe nouns.
* Example: "I have a broken phone."
Examples of Past Participles:
* baked
* written
* eaten
* driven
* sung
* chosen
