                                             my bedroom.
                                                                                     I’ve painted my bedroom.




                   There is paint on Kate’s clothes.           The bedroom was green.  Now it is yellow.
                   She has been painting her bedroom.          She has painted her bedroom.

                   not been finished.                          activity itself.

              C     We use the continuous to say how long (for   We use the simple to say how much, how many
                    something that is still happening):        or how many times (for completed actions):
                         How long have you been reading that         How many pages of that book have
                         book?                                       you read?

                         learning it very long.                      very much yet.



              D   Some verbs (for example, know) are not normally used in continuous forms (be + -ing):
                         I’ve known about the problem for a long time.  (not I’ve been knowing)
                         How long have you had that camera?  (not have you been having)
                  For a list of these verbs, see Unit 4A.  For have, see Unit 17.
                  But note that you can use want and mean in the present perfect continuous (have/has been + -ing):
                         I’ve been meaning to phone Anna, but I keep forgetting.
