Unit 8. Present Perfect (2) (I have done)
(настоящее совершенное время 2)
Study this example situation:
DAVE: Have you travelled a lot, Jane?
JANE: Yes, I've been to lots of places.
DAVE: Really? Have you ever been to China?
JANE: Yes, I've been to China twice.
DAVE: What about India?
JANE: No, I haven't been to India.
When we talk about a period of time that continues from the past until now, we use the Present Perfect (have been / have travelled etc.). Here, Dave and Jane are talking about the places Jane has visited in her life (which is a period that continues until now).
Have you ever eaten caviar? (in your life)
We've never had a car.
"Have you readHamlet?" "No, I haven't read any of Shakespeare's plays."
Susan really loves that film. She's seen it eight times!
What a boring film! It's the most boring film I've ever seen.
In the following examples too the speakers are talking about a period that continues until now
(recently / in the last few days / so far / since breakfast etc.):
Have you heard from George recently?
I've met a lot of people in the last few days.
Everything is going well. We haven't had any problems so far.
I'm hungry. I haven't eaten anything since breakfast. (= from breakfast until now)
It's nice to see you again. We haven't seen each other for a long time.
We use the Present Perfect with today / this morning / this evening etc. when these periods are not finished at the time of speaking
(see also Unit 14. Present Perfect and Past (2) (I have done and I did) (настоящее совершенное и простое прошедшее времена 2)):
I've drunk four cups of coffee today. (perhaps I'll drink more before today is finished)
Have you had a holiday this year (yet)?
I haven't seen Tom this morning. Have you?
Ron hasn't worked very hard this term.
Note that we say "It's the first time something has happened" (Present Perfect}. For example:
Don is having a driving lesson.
He is very nervous and unsure because it is his first lesson.
It's the first time he has driven a car. (not drives) or He has never driven a car before.
Linda has lost her passport again. It's the second time this has happened. (not happens)
This is a lovely meal. It's the first good meal I've had for ages. (not I have)
Bill is phoning his girlfriend again. That's the third time he's phoned her this evening.
