thanks torsten, but, I need to know too about the negative form of present perfect, I don't know how to said for example the following sentence in negative form:
Mr. Wood has written us a letter.

[Ralf]

Hi Estela,

That'd be Mr Wood hasn't (has not) written us a letter. And we haven't (have not) written you either .

Hi Estela,

In addition to the helpful link on this very site which Torsten posted, I find these pages on verb tenses to be very helpful in explaining the different tenses and their uses. In addition to having picture graphs showing when the tenses are used for us visual learners, you can also click on the link 'Complete list of all Present Prefect Forms' on that page to see a complete list of the positive, negative,and interrogative (question) forms of the present perfect.

The same exists for all the English verb tenses, which you can find linked on the left hand side.
