Historia en inglés en pasado simple, continuo y presente perfecto?

Cuando utilizamos el pasado simple hablamos de algo que ocurrió en un momento del pasado.

El presente perfecto se usa para hablar del pasado pero no sobre las cosas cuando ocurrió.

Y el presente continuo para poder hablar de una acción que se esta realizando en el momento :
