Present Perfect

FORM

[HAS/HAVE + PAST
PARTICIPLE]

Use 1.- Unspecified time before now


We use the Present Perfect to say that an action
happened at an unspecified time before now. The
exact time is not important.

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.

Use 1. Unspecified time before now


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.

Use 1.- Time Expressions with Present


Perfect
When we use the Present Perfect it means that something has
happened at some point in our lives before now.
Sometimes, we want to limit the time we are looking in for an
experience. We can do this with expressions such as: in the
last week, in the last year, this week, this month, so far, up
to now, etc.

Examples:
Have you been to Mexico in the last year?
I have seen that movie six times in the last month.
They have had three tests in the last week.
She graduated from university less than three years ago. She has
worked for three different companies so far.
My car has broken down three times this week.

USE 2.- Duration From the Past Until Now


(Non-Continuous Verbs)
o With Non-Continuous Verbs and non-continuous uses of Mixed Verbs,
we use the Present Perfect to show that something started in the past
and has continued up until now. "For five minutes," "for two weeks,"
and "since Tuesday" are all durations which can be used with the
Present Perfect.

Examples:
I have had a cold for two weeks.
She has been in England for six months.
Mary has loved chocolate since she was a little girl.

USE 2.- Duration From the Past Until Now


(Non-Continuous Verbs)
Although the above use of Present Perfect is normally limited to NonContinuous Verbs and non-continuous uses of Mixed Verbs, the words
"live," "work," "teach," and "study" are sometimes used in this way even
though they are NOT Non-Continuous Verbs.
