Presente perfecto VS Presente perfecto subjuntivo

Question

Now I think I understand them for the most part but...

for the presente perfecto I would use that for a sure thing such as...

i have written a book.... he escrito un libro

and

the presente perfecto subjuntivo for feelings... doubt, hope, surprise ect.

my friend doesnt believe that i have written a book... mi amiga no cree que yo haya escrito un libro

o

i am happy that i wrote a book... me alegro de que haya escrito un libro...

o

Me asusto de que usted me haya llamado i am surprised that you have called me.

but I couldn´t say...

me alegro de que he escrito un libro, correct¿?

o Me asusto de que usted me ha llamado

Gracias

Answer 1

I may have used bad examples... I am not familiar with that tense.

You might also look into this which I am surprised wasn't mentioned in your example of "I am happy that I....".

Clipped from article on Spanish subjunctive mood:

The rule: In Spanish, the subjunctive mood is used for the verb in a dependent noun clause when:

1. The subject of the governing verb is different from the subject of the dependent clause ....

subjunctive in noun clauses

Answer 2

so I could say me 'alegro de que he escrito un libro'

Yes, you can, but you'll sound very unusual (rather weird). "Me alegro" is used for appreciations, not declarations. "Having written a book" is a declaration.

I think she wants to say, "I am happy that I have written a book." I would have thought "Me alegro de que he escrito un libro" should work...based on the spanishdict's dictionary's comments about alegrar. How else would one say that? - webdunce, Aug 21, 2009

Answer 4

so I could say me 'alegro de que he escrito un libro'

or I can't say it?

well for the most part is what I was asking correct?

is the Presente perfecto subjuntivo necessary?

Answer 5

i am happy that i wrote a book... me alegro de que haya escrito un libro...

Here begin your mistakes, based on a faulty rule. Here, you normally use subjunctive.

but I couldn´t say...

me alegro de que hayas escrito un libro, correct¿?

Yes, you can.

Sorry, but all the rules you've been given are rubbish, and they fail quite often. Your "faulty" rule says:

the presente perfecto subjuntivo for feelings... doubt, hope, surprise ect.

Siento que has cometido un error (feeling) No sé si lo han hecho (doubt) Me impresiona el saber que aún sigues con vida (surprise)

All those "crappy" rules can be easily rules out with a sentence that sounds perfect in Spanish.
