Student or Learner
Hi, my dear teachers, your help is needed here. I know both the -ing form and the passive -ing form can be used as subject. But can having done and having been done be used as subject? eg,
Having been invited to the party makes him excited.
Not having been invited to the party makes him unhappy.
I never meet such structures. Are they right expressions?
Thank you! I am eager to get your answers.
