What is the difference between the affirmative and negative forms? ​

ответ:  the ways that grammar encodes negative and positive polarity in verb phrases, clauses, or other utterances. Essentially an affirmative (positive) form is used to express the validity or truth of a basic assertion, while a negative form expresses its falsity. Examples are the sentences "Jane is here" and "Jane is not here"; the first is affirmative, while the second is negative.

One day Mr. Earnshaw came back from a long journey with a dirty gipsy child. He explained that he had found him all alone in Liverpool.He wanted to accept the child and asked his own children to share their bedroom with that boy.He called the boy Heathcliff.The children didn't like the boy at first sight. Time passed and little by little Catherine and Heathcliff became great friends but Hindley hated the boy because he became his father's favourite.That's why he often quarreled with his old father.Only when Hindley was sent away to study everybody hoped they would have peace in the house.
