PRESENT PERFECT

The present perfect time we use it when a relation exists between the past and the present. We find the following uses:
When we want to know the present result of something that happened in a moment not defined of the past.

Ej: The secretary you have decided to look for to new job
La secretaria ha decidido buscar un nuevo trabajo

We use It to speak it brings overof an action or situation that began in the past and still continuous

Ej: ¿How long have you worked here?
¿Cuánto tiempo has trabajado aquí?

With the perfect present we use How long ...? (How much time ...?) in questions related to the duration and for (during) or since (from) for the answers
Ej: I've worked here for twelve months (for twenty years, etc).

• They’ve just signed an important contract.
Ellos acaban de firmar un importante contrato.

THE LADY IN RED
by Chris de Burgh

I've never seen you looking solovely
As you did tonight.
I've never seen you shine so bright.
I've never seen so many men ask you
If you wanted to dance.
They're looking for a little romance,
Given half a chance.
And I've never seen that dress you're wearing,
Or the highlights in your hair
That catch your eyes.
I have been blind.

The lady in red is dancing with me,
Cheek to cheek.
There's nobody here, it's just youand me.
It's where I want to be,
But I hardly know this beauty by my side.
I'll never forget the way you look tonight.

I've never seen you looking so gorgeous
As you did tonight.
I've never seen you shine so bright,
You were amazing.
I've never seen so many people
Want to be there by your side.
And when you turned to me and smiled,
It took my breath away.
And I have never had such afeeling,
Such a feeling of complete and utter love
As I do tonight.

The lady in red is dancing with me,
Cheek to cheek.
There's nobody here, there's nobody here,
It's just you and me.
It's where I want to be,
But I hardly know this beauty by my side,
I'll never forget the way you look tonight.
I never will forget the way you look tonight...
The lady in red, the lady in red.
The ladyin red, my lady in red
