Present perfect and past simple

Present perfect and past simple
(I have done and I did)

The present perfect is a present tense. It always tells us something about now.


The past simple tells us only about the past.
Examples:

Jack grew a beard but now he has shaved it off.

They went out after lunch and they have just come back.
Do not use the present perfect if there is no connection with the present (for example, things that happened a long time ago):

The Chinese invented printing.

How many plays did Shakespeare write?
Compare:

Shakespeare wrote many plays.

My sister is a writer. She has written many books.
We use the present perfect to give new information or to announce a recent happening:
Ow! I have cut my finger!

The police have arrested two men in connection with the robbery.
You can use the present perfect with just, already and yet.
Just = ‘a short time ago’
‘Hello. Have you just arrived?’
We use already to say that something happened sooner than expected.
‘He’s already gone.’
Yet = ‘until now’ and shows that the speaker is expecting something to happen. Use yet only in questions and negative sentences.
‘I’ve written the letter but I haven’t posted it yet.’
Do not use the present perfect when you talk about a finished time (for example, yesterday / in 1985 / ten minutes ago). Use a past tense:

I went to bed early last night.

They arrived an hour ago.
Use a past tense to ask When...? What time...?

When did they arrive?

What time did you finish work?

We use the present perfect for a period of time that continues from the past until now.
For example, today, this week, since 1985.

Have you seen Ann recently?

He has lived there for seven years.
I have never played golf.
Past simple
We use the past simple for a finished time in the past.
For example, yesterday, last week, from 1985 to 1991.
It didn’t rain last week.
Did you see Ann on Sunday?
Tom lived in Scotland for ten years. Now he lives in London.
I didn’t play golf when I was on holiday last summer.
