Forms of the -ing form.
                          Active                          Passive
 Simple                   accusing                        being accused
 Perfect                  having accused                  having been accused


   The simple -ing form refers to the present or future or past depending on the
tense of the verb.
   e. g. I am looking forward to seeing you.
           I’ll get used to working at night.
           I appreciated your giving me much of your time.
   The perfect -ing form shows that the action of the -ing form happened
before the action of the verb.
   e. g. He was accused of having deserted his ship.
   We can use the simple -ing form instead of the perfect -ing form with no
difference in meaning.
   e. g. He was accused of deserting his ship.
   The passive -ing form shows that the action is not performed by the subject.
