Hello and welcome to 6 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%.
So it's subject plus have or has plus a past participle.
To make past participles of regular verbs, add ed to the main verb.
So look becomes looked.
But some verbs, like shoot, are irregular.
The past participle of shoot is shot.
You just have to learn your irregular verbs.
That's right.
