Teoria: Presente Perfeito Contínuo (HAVE/HAS + BEEN + ING)

Veja em ação:
Ana: "You look tired!" (Você parece cansado!)
John: "I am! I have been working all day." (Eu estou! Eu estive trabalhando o dia todo.)
Ana: "Has it been raining? The ground is wet." (Esteve chovendo? O chão está molhado.)

Usamos o Presente Perfeito Contínuo para focar na duração de uma ação que começou no passado e continua até agora, ou que acabou de parar e tem um resultado visível no presente.

A fórmula é: Sujeito + HAVE/HAS + BEEN + Verbo com -ING.

HAVE BEEN: Usado com I, You, We, They. (I have been studying.)
HAS BEEN: Usado com He, She, It. (She has been studying.)

Exemplos Práticos da Estrutura:

Para I / You / We / They:

Interrogativa: Have I been working?

Para He / She / It:

Afirmativa: She has (She's) been sleeping.
Negativa: She has not (hasn't) been sleeping.
Interrogativa: Has she been sleeping?
