The present perfect is formed from the present tense of the verb have and the past participle of a verb:

The present perfect continuous is formed with have/has been and the -ing form of the verb:

Use

We use the present perfect tense:

  • for something that started in the past and continues in the present:

They’ve been married for nearly fifty years.
She has lived in Liverpool all her life.

Note: We normally use the present perfect continuous for this:

She has been living in Liverpool all her life.
It’s been raining for hours.

  •  for something we have done several times in the past and continue to do:

I’ve played the guitar ever since I was a teenager.
He has written three books and he is working on another one.
I’ve been watching that programme every week.

We often use a clause with since to show when something started in the past:

They’ve been staying with us since last week.
I have worked here since I left school.
I’ve been watching that programme every week since it started.

  • when we are talking about our experience up to the present:


Note: We often use the adverb ever to talk about experience up to the present:

My last birthday was the worst day I have ever had.

Note: and we use never for the negative form:

Have you ever met George?
Yes, but I’ve never met his wife.

  • for something that happened in the past but is important at the time of speaking:

I can’t get in the house. I’ve lost my keys.
Teresa isn’t at home. I think she has gone shopping.
I’m tired out. I’ve been working all day.

 

 We use the present perfect of be when someone has gone to a place and returned:

A: Where have you been?
B: I’ve just been out to the supermarket.

A: Have you ever been to San Francisco?
B: No, but I’ve been to Los Angeles.

But when someone has not returned we use have/has gone:

A: Where is Maria? I haven’t seen her for weeks.
B: She's gone to Paris for a week. She’ll be back tomorrow.

We often use the present perfect with time adverbials which refer to the recent past:

just; only just; recently;

Scientists have recently discovered a new breed of monkey.
We have just got back from our holidays.

or adverbials which include the present:

ever (in questions); so far; until now; up to now; yet (in questions and negatives)

Have you ever seen a ghost?
Where have you been up to now?
Have you finished your homework yet?
No, so far I’ve only done my history.

WARNING:

We do not use the present perfect with an adverbial which refers to past time which is finished:

I have seen that film yesterday.
We have just bought a new car last week.
When we were children we have been to California.

But we can use it to refer to a time which is not yet finished:

Have you seen Helen today?
We have bought a new car this week.

Hello Andrew international,

In 1, 'for' is the best choice and in 2 it's 'sent'. 'in the last days' is not incorrect, but we usually use it to speak about the end of a past time period, i.e. one that has no connection with the present. In this case, there is a connection with the present implied with the verb 'have met', so it sounds a bit odd to use it.

We're happy to help with questions like this from time to time, but please explain to use what you think the correct answer is, and why, so that we can better help you.

All the best,

Dear Sir
Would you please tell me whether the sentence given below is right or wrong.?
If it is wrong please correct it.
He was the most extra ordinary man I have ever had seen in my life.
Thank you.
Regards
Andrew international

Hello Andrew international,

'extra ordinary' should be spelt 'extraordinary' and the verb form should be either 'have ever seen' or 'had ever seen', but otherwise the sentence is correct.

Hello! Can I use the continous form for to reflect,to seem,to imagine and to remeber?

Hello Rossella,

It is possible with 'reflect', 'imagine' and 'remember', though it's a bit unusual. You'd need a specific reason, for example to refer to something you're doing right now, to use the continuous form with one of them.

I can't think of a context when 'seem' would be used in the continuous.

Thanks a lot again,Kirk.

Hello again,Team!
Once again a good old question ,
What option is more correct in terms of grammar:
e.g. - I came to visit my friend,he opens a door and unexpectedly sees me,and then I say:
1. I have come just to say hello.
2 .I came just to say hello.
It would seem that the option N1 is more appropriate as my visit is present at the moment and hasn't gone to the past(distinctly separated) yet, but still,I often see and hear option N2 in cases like this,or both are correct and why?
Thanks in advance

Hello Slava B,

Before answering your question, I just wanted to point out that 'just' would normally go in a different position: 'I have just come' or 'I just came'.

 

Traditionally 1 would be considered more correct, especially in Britain, and I expect you'd find it more commonly used there. In American English, however, the past simple has come to take the place of the present perfect in some situations, and this is one of them. You would therefore be more likely to hear the simple past there. It's also becoming used more often in British English, too, probably due to the influence of American English. 

All the best,

Hi sir
I know all about that film because i have watched that movie twice or had watched that movie twice which one should be correct

Hi aseel aftab,

The correct form here is 'have watched' because you are describing a present result (knowing the film) of a past action (watching it).

 

Best wishes,

Peter
