Have You Perfected the Perfect Tenses?
Editor’s note: This is the third episode1 of four-part series on verb tenses. Be sure to listen to part one and part two first.
For VOA Learning English, this is Everyday Grammar.
Today we are going to talk about the perfect verb tenses. Perfect tenses generally focus on how apast action affects the present.For example, “I have already eaten.” The suggestion is that thespeaker 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. Ifyou get confused, try replacing “perfect” with “completed” and the time relationship should becomeclearer.
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 theevent 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 Warslast night,” the adverb last night is a specific time.
You cannot say “
You should also use the present perfect to refer to a repeated action in the past. For example, “Ihave 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 adverbnever. “I have never traveled outside of my country” and “I have never smoked in my entire life.”Something that did not happen the past, like not traveling and not smoking, can also have aneffect in the present.
The adverbs never, already, yet and so far are common in the present perfect. Adverbs are oftenthe 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 beforeanother 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, usebefore or by the time followed by the simple past verb. Imagine you were at a New Year’s Eveparty, but you fell asleep before midnight. You could say, “I had already fallen asleep before theNew Year came.”
You can use the past perfect to talk about how an experience from the distant past relates to anexperience from the more recent past. For example, “The soldier wasn’t scared because he hadalready 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. “Mygrandfather passed away before I was born,” has the same meaning as “My grandfather hadpassed 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 actionwill be completed before another future action. For example, “I will have graduated from collegebefore my little brother graduates from high school.”
The future perfect has very limited use because we rarely know a future sequence of events withany certainty. When it is used, the future perfect usually refers to major life events that areplanned years in advance.
And those are the three perfect tenses. Join us next week on Everyday Grammar for anexplanation of the perfect progressive tenses. Words in This Story
