Explanation:

The present perfect tense is the tense we use to talk about events that happened in the past but have present consequences. There are two types of this tense:

• The present perfect simple - used to talk about completed actions that have an influence on the present. The emphasis is on the result of the action.
• The present perfect continuous - used to talk about activities that started in the past and may continue in the present. The emphasis is on the activity itself.
