Only she knows how to play football. (Given)

No one knows to play football except her. (Negative)

• When transforming an affirmative sentence into a negative one, the meaning or the main idea of the sentence must not change.
• The word 'not', 'no one' etc are added to convert the form of saying.
• When the word 'only' is mentioned in the sentence, then 'except' is used in the negative form.
