Welcome to this tutorial.
Today we're going to talk about the present perfect tense.
Let's get started.
Now we use the Prism perfect to describe past events which are connected to the present.
Although this tends can be used to describe different situations.
Have a look a deep sample over here.
Sam has lost his keys meaning that he is looking for his keys and he still hasn't found them
we use have or hasn't.
Plus verb EDI or just a verb.
And for the negative we use haven't or hasn't.
Plus verb EDI or just the verb has a look at the examples we know positive sentence.
