We use perfect aspect to look back from a specific time and talk about things up to that time or about things that are important at that time.

We use the present perfect to look back from the present:

I have always enjoyed working in Italy. [and I still do]
She has left home, so she cannot answer the phone.

We use the past perfect to look back from a time in the past:

It was 2006. I had enjoyed working in Italy for the past five years.
She had left home, so she could not answer the phone.

We use will with the perfect to look back from a time in the future:

By next year I will have worked in Italy for 15 years.
She will have left home by 8.30, so she will not be able to answer the phone.

Present perfect

We use the present perfect:

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

They've been married for nearly 50 years.
She has lived in Liverpool all her life.

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

I've seen that film before.
I've played the guitar ever since I was a teenager.
He has written three books and he is working on another one.

  • for something that happened in the past but is important in the present:

I can't get in the house. I've lost my keys.
Teresa isn't at home. I think she has gone shopping.

We normally use the present perfect continuous to emphasise that something is still continuing in the present:

It's been raining for hours.
I'm tired out. I've been working all day.

Past perfect

We use the past perfect:

  • for something that started in the past and continued up to a later time in the past:

When George died, he and Anne had been married for nearly 50 years.
She didn't want to move. She had lived in Liverpool all her life.

  • when we are reporting our experience up to a point in the past:

My eighteenth birthday was the worst day I had ever had.
I was pleased to meet George. I hadn't met him before, even though I had met his wife several times.

  • for something that happened in the past and is important at a later time in the past:

I couldn't get into the house. I had lost my keys.
Teresa wasn't at home. She had gone shopping.

We use the past perfect continuous to show that something started in the past and continued up to a time in the past or was important at that time in the past:

Everything was wet. It had been raining for hours.
He was a wonderful guitarist. He had been playing ever since he was a teenager.

Modals with the perfect

We use will with the perfect to show that something will be complete at or before some time in the future:

In a few years they will have discovered a cure for the common cold.
I can come out tonight. I'll have finished my homework by then.

We use would with the perfect to refer to something that did not happen in the past:

If you had asked me, I would have helped you.
I would have helped you, but you didn't ask me.
You didn't ask me or I would have helped you.

We use other modals with the perfect when we are looking back from a point in time. The point of time may be in the future:

We'll meet again next week. We might have finished the work by then.
I will phone at six o'clock. He should have got home by then.

or the present:

It's getting late. They should have arrived by now.
He's still not here. He must have missed his train.

or the past:

I wasn't feeling well. I must have eaten something bad.
I checked my mobile phone. She could have left a message.

In the English translation of Police by Jo Nesbo, the first sentence is something like: It had been cold September. The book is actually full of simple sentences with past perfect that are grammatically correct but do not describe anything that happened before a past action. Will you explain me the rational for using the past perfect instead of preterit?

Hello,

It's not really possible to say for sure why a particular verb form is chosen in a sentence without seeing the context. However, my guess would be that in this case, the cold September is described from the point of view of someone looking back at the end of September. These are the two time references.

hello, everyone i am new user, firstly i would like to say hello to you guys

hello admin team, i am a student at university and i start my second year in september, i would like to improve my english skills, especially helping with writing my assignment. but i am very concern and worry to face problem with start writing up my assignment. your help appreciate in advance. p.s could you correct this paragraph for me for example how could be written differently more academically. many thanks

Why in present perfect you can say "It´s been raining all day" but not "it has been raining all day"
Are there more cases like this one?

Hello Javier,

Both of those sentence are correct; you can use the contraction ('It's...') or not ('It has...').

Best wishes,

Hi)
I have a question about the following sentence: "it has been raining often lately. Autumn came ( or has come??)
Could you, please, explain which form is correct? Thank you.

Hi Kuzia,

The most likely is 'has come' as the speaker is probably commenting on a new event (the arrival of autumn). However, 'came' is also possible, depending on the context.

Best wishes,

Thanks Peter for your last explanation. And I have another confusing about " last year" and " in the last year". As we knew, when time clause " last year" in the sentence which means in the past but if " in the last year" we have to use present perfect tense. Even though I have read the difference between them. "Last year" means the year before now, and it is considered a specific time which requires Simple Past. "In the last year" means from 365 days ago until now. It is not considered a specific time, so it requires Present Perfect. But I am still confusing. In my analysing point, there is not a difference at all. " Last year " is also included 365 days as same as " In the last year". Could you please explain clearer.

Thank you very much!
Anna
