In this lesson, I'm going to talk about the difference between the present perfect tense and the present perfect, continuous tense.

Many people ask about the difference between these two.

So I'm going to talk about how to make these tenses and sometimes when you might want to use them.

First of all, I want to begin with sort of visual of these two grammar points.

I'm going to start with the present perfect tense here, though.

So you might have seen another video on this channel about the present perfect tense.

But I'm going to review quickly here the present perfect tense.

I'm going to talk about two uses of the present perfect tense.

They are first, uh, that we use the present perfect tense to express life experience at a non specific time in the past.

So this means something that we did in the past, meaning before the present time here on a timeline Uh, but the exact point in time is not important.

So we use this for perhaps our job experience or our travel experience.

For example, with expressions like I have been to France or I have worked at X y Z company, for example, the specific time is not important, so we can use the present perfect tense to describe those things.

The second point I want to talk about with the present perfect tense is how we use it to refer to an action that started in the past and that continues to the present or the effects of that action started in the past and continued to the present.

Rather so on our timeline, it sort of looks a little bit like this.

Some action started in the past, and the action has continued to the present.

In other words, So these are the two points I want to talk about with the present perfect tense.

Um, let's take a look, then to review how to make the present perfect tense when you're making a statement with the present perfect tense, you might use a pattern like this.

So if your subject is I will you are they will use that plus have, plus the past participle form of a verb.

You might use four or since depending on the, uh the point that you're using here and you'll finish the sentence with the extra information.

If your subject, however, is he or she or it will use has instead of have and then follow it with the past participle form of the verb, perhaps four or since depending on your sentence and your information.

So some examples of this are I have been to Italy, so have follows this pattern and been is the past participle form of the verb to be.

I'm using 0.2 in this in this bullet pointed list.

Second, this is an action that started in the past and that continues to the present.

He has studied English for six months, So this is an action that's probably still in progress.

I want to review how to make questions with this tense.

So for simple yes and no questions we can use patterns like this has if your subject is he or she or it will begin with past.

If your subject is I will you or they will begin with have.

Plus the past participle form of the verb blessed again, this four or since perhaps and then your extra information at the end of the sentence with have it's the same.

Were they plus past participle, verbs and maybe four?

Or since so a couple examples of this has she finished her homework.

Is the past participle form of the verb finish?

Has she finished her homework and have they cleaned up the house?

So these air questions asking, Has this action been completed so before now, in other words, these two actions in this case, her homework and the housecleaning.

But the time at which the action was finished is not so important in these questions.

The speaker, the person asking the question on Lee, wants to know.

That's why the present perfect tense is being used to ask the question.

Let's look at a different question pattern.

This is when you want to get information.

And then we follow the same pattern we saw up here.

So, for example, uh, we could use question word.

Plus, has he and past participle verb form plus four or since perhaps, and her extra information or question word plus have and or I will you they past participle, verbs and four percents.

So one great example of this is where have you been?

So again, the speaker is asking in the in the period of time before the present, Where was the listener?

Where have you been in this period of time?

So we use thes these types of questions just to ask about things that happened.

Or maybe that continued to happen before the present.

But maybe not at a specific point in time.

And since commonly with this point right here, the continuing action point.

Remember, we used four before a length of time, like 43 years for five hours.

And we used since to refer to a specific point in time.

Okay, so with that in mind, let's take a look then at the present perfect, continuous tents.

So, President, perfect, Continuous tense.

We use this for actions that started in the past and continue to the present.

So, just like this one that we talked about here, but this point, it emphasizes a continuing action.

So we use this for something that we're putting our efforts into.

Now we're putting our focus into right now or for an interrupted action, for example.

So we'll introduce some examples here in just a moment to make three present.

The pattern is quite similar to the present Perfect tense.

We have this same change with the subject.

Depending on the subject will use I, we, you they plus half.

Then we'll use been, but then we'll follow it instead of with the past participle form of the verb will use the progressive or the content continuous form of the verb, the i N g form of the verb.

And here we can use four or since and the ending information.

The only difference is will use has instead of half here and then we'll follow it with been progressive form of the verb and four or since depending on your statement.
