Explicação:

Present Perfect

Present Perfect é um tempo verbal que expressa uma ação no passado, cujo  tempo é desconhecido ou não importante no contexto. O que importa quando usamos esse tempo verbal é a ênfase que se dá à reação da ação, que interfere no presente e não a ação em si. Podemos dizer que é um tempo verbal passado com  uma forte relação com o presente.

No Present Perfect utilizamos o verbo "to have" como verbo auxiliar, nas seguintes conjugações:

Have para os pronomes I, you, we, they;

Has para os pronomes he, she, it.

Forma Afirmativa

Para a construir frases afirmativas no Present Perfect Simple, utiliza-se a seguinte estrutura:

Sujeito + verbo auxiliar to have no Simple Present + verbo principal no Particípio Passado + complemento

Exemplo:

You have studied English.  / Você estudou inglês.

Forma Negativa

As frases negativas no Present Perfect Simple incluem o “not” após o verbo auxiliar e seguem a seguinte estrutura:

Sujeito + verbo auxiliar to have no Simple Present + not + verbo principal no Particípio Passado + complemento

* Contrações:
