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 sir
Thanks for replying, I have another question too. what's the difference between these two sentences?
I like to shopping at the mall.
I like to shop at the mall.
Is the first one grammatically right? what about '' I go to shopping'' or '' I go shopping'' which one is correct?

Hello monovar,

'I like to shopping at the mall' is not grammatically correct.

'I like to shop at the mall' is fine. This describes how you like to spend some of your time.

'I go to shopping'' is not correct.

'I go shopping' is correct. It describes how you spend your time, not whether or not you enjoy it.

Hello
Is this sentence right?
Todays due to advanced achievements of human such as internet and electronical tools, they are experiencing modern and also complex life.
is the using of present continuous right?
And also electronic tools or electronical tools, which one is more correct?

Hello monavar,

The present continuous or the present simple could both work here. One or the other might be better depending on what you want to communicate.

'electronical' is not a word; 'electronic' is. Here, again depending on what you mean, you could use 'electronic' or 'electrical'.

By the way, 'todays' is not correct -- I'd recommend 'today' instead.

HelloTeam,

Can u tell the 'Voice' (Active / Passive) of the below sentence:

"They’ve been married for nearly fifty years."

Hello RamActaar,

There is no passive form possible here because there is no object of the verb. Passive sentences are only possible with transitive verbs (i.e. verbs with direct objects). The construction here is actually VERB + ADJECTIVE:

They are married. [are = verb; married = adjective]

They were married.

They have been married for...

 

Best wishes,

I am having trouble with this type of sentence like I have been tired, he has been found guilty, he has been there... do they mean I was tired and still tired, he was guilty and still guilty and he was there and still there ???

Hello Joy71,

The present perfect can be used in different ways, but, yes, that's more or less the general idea. These uses are described in more detail above and I'd also recommend our talking about the past page, where you it is contrasted with other tenses.

Hello amrita_enakshi,

I'm afraid we don't provide the service of providing explanations like this, particularly when the sentences don't come from our site or seem to be from a different class or learning resource. I'd encourage you to consult with your teacher if you have one. If that's not possible and you'd like to ask us about one of these sentences, explaining in detail to us what you understand or don't understand, then we'll be happy to help you.

You might also want to consider taking a British Council class if you seek this kind of instruction.
