Yes you got it right. Another alternative would be "Would you like one more coffee?"

Please notice that I have edited my post above and added more information.

can you tell me where i can find a list of verbs??
please señor

Yes I can tell you. Here is a list of 1455 verbs in Alphabetical order:
http://www.logosconjugator.org/newverb/verba_dba.verba_main.create_lang_page?lang=TR&total_verb=1455

There is also a book called "201 Turkish Verbs". I recently bought this book to check if its any usefull and yes I can suggest that book to others. In fact some of my students have started using it. It has conjugations of 201 common verbs. Unfortunately it has only the translation of the infinitive. It costs only £7.19

There is also a website for verb conjugations but it doesnt have the translations.
http://www.verbix.com/languages/turkish.shtml

Except these sources there is a program called winmekmak and it has both the conjugations and translations and I think its translations are usually accurate provided that you don't make a typo.

All these sources, except the book, can be found on the list here in this language forum we are writing right now.
There is a stick thread on top:

"Most comprehensive list of websites on Turkish as a foreign language (please contribute to the list)"

Any other questions?
