Form
The present perfect, in its affirmative form, has this structure:
Subject + have/has + past participle + …
- Have/has: the third person singular changes from have to has;
- Regular past participles are formed by adding -d or -ed to the base form of verbs;
- Irregular past participles have to be learned by heart.
Subject | have/has | Past Participle |
---|---|---|
I | have | worked |
You | have | worked |
He | has | worked |
She | has | worked |
It | has | worked |
We | have | worked |
You | have | worked |
They | have | worked |
Short forms of the affirmative form are: I’ve – you’ve – he’s…
With the present perfect tense we often use time expressions like: ever, never, before, yet, just, already, still, so far, up until now…
