Forming negative present perfect continuous sentences

We can form negative present perfect continuous tense sentences by putting the word "not" after the helping verb of the sentence (has/have for present perfect continuous tense).

Example

1. She has been working on her project all day.

   • She has not been working on her project all day.
   • She hasn't been working on her project all day.

2. They have been practicing for the competition this week.

   • They have not been practicing for the competition this week.
   • They haven't been practicing for the competition this week.

4. You have been having breakfast since last month.
