The perfect aspect

In the mind of an English speaker, there's a clear difference between talking about an event that happened in the past and talking about something that has happened. The difference is whether there's an effect on the speaker right now.
For example, if you say "I ate" it's just a fact - you ate at some time in the past. It doesn't have any connection to how you feel right now.
But if you say "I've eaten", that expresses
the idea that you ate something, and it's still affecting you. Maybe you feel full. Maybe you don't want to eat another meal. You are not only talking about a past action, but also about the present effect of that action.

Visually, think about it like this:
simple past tense: I ate.
present perfect tense: I've eaten.
The name for this way of speaking and understanding sentences is the "perfect aspect". Perfect aspect is used in a few different kinds of situations:

  • For talking about your experiences ("I've never met her.")
  • For talking about things that are still going on ("We've been together for three years.")
  • For talking about something you expected to happen ("Have you called him back yet?")
But the big question is, how do you learn how to use perfect aspect correctly? Do you just read this email and remember this list of rules? That probably wouldn't work. A better way to learn is to look at examples of how people use perfect aspect in real situations. This list of sentences that use perfect aspect will help you to get started:

Read those sentences, and try to "feel" why the speaker would choose "have done" instead of "did".                                              ("Year of English")

Each of these lessons includes a perfect aspect verb. These include:
·     present perfect ("have done", "has been", "has gone", etc.)
·     past perfect ("had seen", "had known", etc.). There's also a separate category that includes only past perfect lessons.
·     future perfect ("will have done")
·     perfect progressive ("have been doing", "has been going", "had been waiting", "will have been doing", etc.)
There's also a post in the Concepts section explaining Perfect Aspect.
