The present perfect

How do we make the present perfect?

Subject + have/has + past participle (voltooid deelwoord)

Subject "have/has" Past participle
I/you/he/we/they/you have/has worked.

 

Remember: past participle often ends with –ed, but not when a verb is irregular.

Subject "have/has" Past participle
I/you/he/we/they/you have/has done.

 

 

We use the present perfect when 
- we talk about something that happened in the past but is still relevant at this moment.
- something started at a point in the past but is still going on.
