Hello, and welcome to six minute grammar with me, Catherine and me, Neil.
Hello.
Today we're talking about the present perfect and the past simple tenses.
Yes.
We're going to tell you how to form them and give you three rules to help you decide which one to use and when.
We'll also look at using ever and never with the present perfect and we'll.
Finish with a quiz.
Right then let's start with the present perfect.
And here's our first example.
I've looked at the sales figures.
They've shot up by 20%.

But some verbs like shoot are irregular.
The past participle of shoot is shot.
You just have to learn your irregular verbs.
Thats right.
