Grammar notes

Affirmative sentences in the simple present tense are changed into negatives by putting do not or does not before the verb. Affirmative sentences in the simple past tense are changed into negatives by putting did not before the verb.

Answer 2

Negative sentences are declarative statements. That is, they relay information believed to be true. Negative sentences are typically formed by adding the word "not" after the helping verb. The most popular helping verbs are a form of "to be," including "am," "is," "are," "was" and "were."

Negative sentences can also make use of the words "do" or "will" (including "do," "did," and "does") before "not." In any of these constructs, it's possible to substitute "does not" with the contraction "doesn't." Other examples include didn't, isn't, wasn't, weren't, and won't. If you're writing a formal document or an academic essay, it's best not to use contractions. However, for informal writing, including blogging and social media posts, contractions are perfectly acceptable.
