information of present perfect
The present perfect
The present perfect, formed from auxiliary have or has with a past participle, is usually used to talk about the past in relation to the present. It suggests a connection between something that happened in the past and a present time, often referring to an action in the past which has a result now, e.g:
I’ve cut my finger.
They’ve forgotten to bring their tickets.
Your parents have arrived.
We often use the present perfect to give ‘new’ information, reporting events that have occurred just before the present time, e.g:
There’s been a serious accident on the bypass.
I’ve won a competition.
Paula has got a new job.
