I – Present perfect
The simple present perfect is used for past actions that have consequences in the present. For example, « I have lost my keys » implicates that I cannot open the door now.
⚠️Don’t forget that the past participle can be irregular!

II – Continuous present
The continuous present perfect is used in three different contexts (see picture on the left). Do not forget that state verbs are used with the present perfect. State verbs express a state or a condition rather than an action (to be sick, to be married, to know something, etc.)
To use the continuous present perfect the auxiliary have is still used AND “been” is added just after. Then the present participle of the chosen verb is added. The present participles are formed by adding “-ing” to the base form of the verb.
