Present Perfect 
 We use the Present Perfect to say that an action happened at an unspecified 
time before now. The exact time is not important. You CANNOT use the 
Present Perfect with specific time expressions such as: yesterday, one year 
ago, last week, when I was a child, when I lived in Japan, at that moment, 
that day, one day, etc. We CAN use the Present Perfect with unspecific 
expressions such as: ever, never, once, many times, several times, before, so 
far, already, yet, etc.
EXAMPLES 
I have seen that movie twenty times. 
I think I have met him once before. 
There have been many earthquakes in California. 
People have traveled to the Moon. 
People have not traveled to Mars. 
Have you read the book yet? 
Nobody has ever climbed that mountain. 
A: Has there ever been a war in the United States? 
B: Yes, there has been a war in the United States.
Presente Perfecto (Present Perfect Tense) 
 El Presente Perfecto en el idioma inglés es un tiempo verbal que se utiliza 
para referirnos a acciones que suceden en un pasado reciente y que guardan 
alguna relación con el presente. Su equivalente en el idioma español es 
el Pretérito Perfecto: 
 I have sent the letter. 
Yo he enviado la carta. 
(Indica que la acción acaba de suceder) 
 Para poder construir la forma afirmativa del Presente Perfecto debemos 
utilizar como auxiliar el verbo TO HAVE en Presente Simple y acompañado por 
el verbo principal en su Pasado Participio (ya sean verbos regulares o verbos 
irregulares):
EXAMPLES 
I have bought a new dress. Yo he comprado un nuevo vestido. 
You have studied the lesson. Tú has estudiado la lección. 
He has broken the window. Él ha roto la ventana. 
She has lost the keys. Ella ha perdido las llaves.
Notes: 
The written lesson is below. 
Links to quizzes, tests, etc. are to the left. 
The present perfect is formed by combining the auxiliary verb "has" 
I have studied. 
He has written a letter to María. 
We have been stranded for six days.
PRESENT PERFECTO (ARE) 
 Whiz-deletion removes the boldfaced 
markers, since they are predictable (by 
native speakers, at least) and contribute 
nothing to the meaning, just the structure. 
This works fine in speech, where confusions 
can be cleared up immediately, but is not 
always the best strategy for written English
