1. Present Perfect / Past simple

2. Remember that we use the present perfect for things that happened in the past but are important in the present, eg
We have visited Paris. (and we can tell you about it now)
I have washed the dishes. (so you don’t have to do them now)
Have you read this book? (or do you want to read it now / can you tell me
about it now?)
We often use the time expressions for, since, just, yet, already, before, ever and never with Present Perfect
I have lived here for years.
Have you seen Fiona since yesterday?
He has never eaten Greek food before!
Remember that in the present perfect, we do not say when something happened,
I have seen that film. (not I have seen that film last week.)
We use the past simple for things that have finished. We also use the past simple if we want to say when something happened,
He knocked the door and shouted my name. (finished actions)
I spoke to Donna last night. (so you don’t need to speak to her today)

3. For the past simple, we use the time expressions yesterday, last week, in June, in 2005, when I was seven, etc, eg
We lived there when I was a little boy.
I bought some great new clothes on Saturday.
The lesson started half an hour ago!
Sometimes we use the present perfect and the past simple together.The present perfect usually introduces the subject, and the past simple gives us more information,
Ben has met Tom. (present perfect) He met him yesterday. (past simple).
I have read that book. (present perfect) It was great. (past simple).
We have been to London. (present perfect) We went there in (past
simple).

4. We use the present perfect to give new information but if we continue to talk about it, we normally use the past simple:
* A: Ow! I've burnt myself.
B: How did you do that? (not 'have you done')
A: I picked up a hot dish. (not 'have picked')
* A: Look! Somebody has spilt milk on the carpet.
B: Well, it wasn't me. I didn't do it. (not 'hasn't been ... haven't done')
A: I wonder who it was then. (not 'who it has been')
The present perfect is a present tense. It always tells us something about now. 'Tom has lost his key' = he doesn't have his key now
The past simple tells us only about the past. If somebody says 'Tom lost his key', we don't know whether he has it now or not. We only know that he lost it at some time in the past.
