Forming negative present perfect sentences

We have learned in the previous lessons that to form basic negative sentences, we can put "not" after the helping verb of a sentence. We can form negative present perfect sentences by simply putting "not" after the helping verb of the sentence (has/have).

Example

We have highlighted the helping verb of each sentence with the color yellow and not (or contracted form n't) with the color red.

   • She has not finished her homework.
   • She hasn't finished her homework.

2. They have watched the movie.

   • They have not watched the movie.
   • They haven't watched the movie.
