In negative sentences, we put not between the form of be and the verb.
In questions, we simply swop the places of subject and the form of be.
Examples:
| He is dreaming. | He is not dreaming. | Is he dreaming? |
| They are reading. | They are not reading. | Are they reading? |
| I am working. | I am not working. | Am I working? |
