Hi Guys,
Welcome to the video
In this video, we'll be looking at the present perfect tense
First we're going to focus on the form,
or the actual words that you need to use to form the tense
Now, the present perfect is a compound tense
Meaning that you need two verbs together
to...aahhh...form it
Aaahhh, first you have an auxiliary verb
which is followed by the main verb
In the present perfect
The auxiliary verb is 'have'
Now, this is important, so pay attention!
The auxiliary verb must change form to agree with the subject
Then we have the main verb
which is in the past participle form
For example, I could say 'I have done'
Or, 'he has done'
Okay, now let's take a look at the form
for statements- both positive and negative
in a positive statement you have the subject
plus the auxiliary verb, and then the main verb
For example,...
Now, for a negative statement
you need to put the negative particle
between the auxiliary verb
and the main verb
Now, the...uhhh...not
can also be contracted to 'haven't'
or 'hasn't'
Okay...now let's take a look at questions
both positive and negative
The main thing about questions is you have to switch the order
of the subject and the auxiliary verb
So the sentence now begins with the auxiliary verb
plus the subject
Now, just as in the negative statement
in a negative question, the negative particle 'not'
goes after the auxiliary verb
So, we have....
Now, in the question form
It is pretty much always contracted
to 'n't',...'haven't'
because 'have not you done?' sounds a little bit awkward
it's too long. So everybody says 'haven't you done?'
