Hello everybody. Welcome to the second term in this new year 2021.
In unit number 3, we are going to learn the present perfect tense.
We use present perfect to talk about actions that happened in the past and have a result in the present.
To form the present perfect, we use has/have + past participle. An example:
Affirmative: I have eaten
Negative: You haven´t eaten
Interrogative: Has she eaten? Yes, she has/ No, she hasn´t
To form the past participle of regular verbs, we add -ed to the verb: play- played.
You have to study the past participle of irregular verbs.
Here you have a video with the explanation of present perfect and more examples:
