Answer 1

Respuesta:

I have known him for years.

He has been studying English since he was five.

We have been waiting for the train for forty minutes.

We have not played tennis since last summer.

We haven't played tennis since last summer.

Since ¿When have you been here?

Explicación:

Si la acción sigue en curso, para especificar desde cuando sucede, usaremos únicamente since seguido de la fecha o del momento. Cuando usamos since el verbo principal está en presente perfecto: I've been here since 2 (o'clock).

La preposición “for” se usa para expresar la duración de una acción, el periodo de una acción o un evento. Por ejemplo: “I've lived here for 8 months”. He vivido aquí durante 8 meses.
