Perfect Continuous Tenses
Past Participle
• Past participles are used for all perfect tense
forms of a verb and in the passive voice in
English.
• For regular verbs, we normally add (-ed) to
form its past participle.
• Unfortunately for irregular verbs there are no
rules and it is just a matter of practice.
