Unit 4 A: Present Perfect Tense

The present perfect is used to talk about a recent past action which is still true in the present. It is used to talk about past experiences too when we don´t mention when the action happened. To form the present perfect we use HAVE/HAS as auxiliary verb and the past participle of the main verb. Practise the structure doing these activities. And if you want to know which time expressions are used with the present perfect and which ones with the past simple try this exercise.
