Never mind the past. What's done is done. What is really relevant is the effect of the past on the present. For that we use the Present Perfect tense. Got it?
Don't get it? Well, let's have a good look at the Present Perfect and the Present Perfect Progressive tenses.
In my mind, I have been president now for over 5 years.
I have been waiting for you to see a doctor for over 5 years now.
As is the case with other verb tenses, the present perfect tense has its progressive form. How are these tenses formed? Let’s take a look.
All perfect verb tenses are so named because they use the auxiliary
verb “HAVE” followed by a participle. In the case of the Present
Perfect tense, this form is used:
HAVE + Past Participle
EXAMPLE: Len has taught English for over 19 years.
The word “taught” is a past participle.
OK. Let's have a look at a few more examples.
Alright, student. Is this clear to you? Yes? Good. So, let's look at the Present Perfect Progressive now.
In the case of the Present Perfect Progressive tense, this form is used:
HAVE + Past Participle + Present Participle
EXAMPLE: Len has been teaching English since 9:30 AM.
Note that the past participle in the Present Perfect Progressive tense
is always “BEEN”.
Brainstorm: Why do we always use “been” with the Present Perfect Progressive?
It is not so hard to understand the forms of these verb tenses, but how do we use them? And what do they mean? Well, let’s take a look at a couple of examples and see if we can figure this out.
Examples:
[] Len has eaten sushi before.
[] Len has been eating hotdogs all his life.
In the first case, we mean that Len ate sushi at some time in the past.
We also think that his experience is still related to the present time.
However, in the second case, we mean that Len started something in the
past time that is continuing even now. The Present Perfect focuses on
experience. The Present Perfect Progressive focuses on continuation.
Often, especially in questions, the Present Perfect is used to talk about experience. For example: Have you sung in a karaoke box before?
There is also a tendency to use the Present Perfect Progressive when speaking about the “near” past and the Present Perfect when talking about a time in the past further removed from the present time. Compare these sentences.

Students often confuse the use of the Simple Past and the Present Perfect. It is helpful to remember that the Simple Past is used for that which was completed in the past (and is no longer relevant in the present time).
So, when do we use the Present Perfect and Present Perfect Progressive tenses? There are essentially three general occasions:
Note: Some words suggest, or even demand, the use of the Present Perfect; others are used only with the Past Tense.
The Grammarian says: Never use ago with the Present Perfect; use it only with the Simple Past or Past Progressive. On the other hand, since and for are often used with the Present Perfect.
Compare the following sentences and determine when we use Present Perfect (or Present Perfect Progressive) with the words since and for.
