1. Review: the present perfect tense
The present perfect is used for actions that have been completed before now.
It is summarised as:
time: not finished
*Not finished times = now, today, this week, this month, my life, etc.
It is made by:
have + p.p.
*Perfect participle (p.p.) = gone, done, seen, eaten etc.
|I have finished my work.||They have visited Singapore six or seven times this year.|
|Peter has retired.||Her parents have taken her bicycle to the shop.|
2. Turning the present perfect into its passive voice
The passive voice changes ‘x did y’ to ‘y had something done to it by x’.
To turn the present perfect into its passive voice:
1. swap the subject and object
2. change ‘have + p.p.’ into ‘have been + p.p.’
|Active sentence||Passive sentence|

|They have finished the repairs.||The repairs have been finished.|
|The salesman has sold that car.||That car has been sold.|
