Present Perfect vs Present Perfect Continuous(part I)
We form past perfect with had + past participle
I/you/he/she/it/we/they had worked .
I/you/he/she/it/we/they had not( hadn’t ) worked.
Had I/you/he/she/it/we/they worked?
had = ‘d had not = hadn’t
Some verbs are ‘ regular’ , other verbs are ‘irregular’ :
- The past participle of regular verbs has an –ed ending ( example: clean –cleaned , play–played )
