2. Present Perfect
El presente perfecto se usa para expresar acciones que ocurrieron en un
tiempo no concreto antes de ahora. El tiempo específico no es importante.
Por lo tanto, no solemos usar expresiones de tiempo específicas ("this
morning", "yesterday", "last year"...) con el presente perfecto.
