                                       TUESDAY               I've been here since Tuesday          NOW


                 We use the present perfect, not the present, to say how long something has continued up to now.

                 I've been here since Tuesday. (NOT / am here since Tuesday.)
                 I've known John for ten years. (NOT / know John for ten years.)
                 We can say how long with since or for.
                We use since when we give the beginning of the time (for example since Tuesday).
                 We use for when we give the length of the time (for example for three days).

                 I've been here since Tuesday.    I've been here for three days. (NOT... since three days.)
                 I've known Mary since 2005.      I've known Mary for a very long time.
                 I've had this car since April.  I've had this car for six months.

                    Put in since or for.

                 Be, know and have are non-progressive verbs (see pages 30-31). With most other verbs, we use the present
                 perfect progressive (see next page) to say how long things have continued up to now.
                 How long have you been waiting?







               In some answers, both contracted forms (for example I'm, don't) and full                     PERFECT TENSES  65
               forms (for example lam, do not) are possible. Normally both are correct.
