The Present Perfect is a tense used to talk about completed actions which have occurred in the past which are connected to the present and still have effects on it.
When expressed in its Affirmative form, the verb confirms something about the subject.
The Affirmative form of the verb “to work” has this structure:
Subject + auxiliary verb “to have” + past participle* (“has” for third person singular).
|SUBJECT||AUXILIARY VERB||PAST PARTICIPLE*||SHORT FORM|
*Short version of the Affirmative form is: “have: ‘ve, has: ‘s.”
- Results in the present

The Present Perfect in its Affirmative form has this structure:
Subject + auxiliary verb “to have” + past participle* (e.g. I have worked.) (“has” for third person singular).
*The past participle indicates past or completed actions. It is formed by adding -d or -ed, to the base form of regular verbs.
—”It has rained the whole morning.” = We use the Present Perfect because this finished action happened in the past but still has effects on the present, for example in this case the effect could be that the streets are still wet.
> “It rained the whole morning.” = We use the Past Simple because we talk about a finished past action without the need to emphasize its effects on the present.
NOTE: Irregular verbs have different fixed forms which need to be studied by heart. The past participle is usually used to form the perfect tenses.
