Today we are going to talk about the
perfect verb tenses. Perfect tenses generally focus on how a past action
affects the present.For example, “I have already eaten.” The suggestion is that
the speaker is not hungry.
Perfect verb tenses are the most difficult
for English learners. The term “perfect” can be confusing. What does grammar
have to do with not making mistakes? When you are talking about grammar, perfect has a different meaning. It comes from the Latin
word perfectum, which means “complete.”
The most important thing to remember is
the perfect tenses always refer to completed actions. If you get confused, try
replacing “perfect” with “completed” and the time relationship should become
clearer.

Present
perfect
We will start with the present perfect.
You form the present perfect using has or have followed by a past participle verb. For example, “I have seen Star Wars.”
The use of the present perfect here
gives us three pieces of information. First, it tells us that the event is
finished. Second, it tells us that the exact time of the action is unknown or
unimportant. Third, it suggests that the experience of seeing Star Wars has some effect in the present.
One of the most difficult distinctions
for English learners to make is the difference between the simple past
and present perfect.
Remember, when there is a specific time,
you use the simple past. In the sentence “I saw Star Wars last night,” the adverb last night is a specific time.
You cannot say “I have seen Star Wars last night.” But, you could say, “I have seen Star Wars before”
or “in
the past” or “three times.”
You should also use the present perfect
to refer to a repeated action in the past. For example, “I have taken that test
four times.” The exact time of each action is not important.
You can also use the present perfect to
describe an action that did not happen, using the adverb never. “I have never traveled outside of my country” and “I
have never smoked in my entire life.” Something that did not happen in the
past, like not traveling and not smoking, can also have an effect in the
present.
The adverbs never, already, yet and so far are common in the present perfect. Adverbs are
often the best indicators of which verb tense to use.
Past
Perfect
Now let us look at the past perfect. The
past perfect describes an activity that was finished before another event in
the past. For example, “She had already had a baby before she graduated.”
To form the past perfect, use had followed by a past participle verb. For the
second action, use before or by the time followed by the simple past verb. Imagine you were
at a New Year’s Eve party, but you fell asleep before midnight. You could say,
“I had already fallen asleep before the New Year came.”
You can use the past perfect to talk
about how an experience from the distant past relates to an experience from the
more recent past. For example, “The soldier wasn’t scared because he had already been in battle before.”
In other words, battle was not a new
experience for the soldier.
If the time relationship is clear, you
can choose between the past perfect and the simple past. “My grandfather passed
away before I was born,” has the same meaning as “My grandfather had passed
away before I was born.”
The past perfect just emphasizes that
the first action was completed before the second action.
Future
perfect
Let us move on to the future perfect.
Use the future perfect when you know that one future action will be completed
before another future action. For example, “I will have graduated from college
before my little brother graduates from high school.”
The future perfect has very limited use
because we rarely know a future sequence of events with any certainty. When it
is used, the future perfect usually refers to major life events that are
planned years in advance.
And those are the three perfect tenses.
Join us next week on Everyday Grammar for an explanation of the perfect
progressive tenses.
