Forming negative sentences

To make a simple present tense sentence negative, you generally use the auxiliary verb "do" (or "does" for third person singular subjects) followed by "not" and the base form of the main verb. Here’s a guide with examples:

Structure:

For plural subjects and "I," "you,": subject + do not (don't) + base form of the verb
For third person singular subjects "he," "she," and "it": subject + does not (doesn't) + base form of the verb

Let's take a look at a few examples

I walk to school. -> I do not walk to school./I don't walk to school.

In this sentence, "I" is the subject, "do not" (or "don't") is the negative form, and "walk" is the base form of the verb.
She walks to school. -> She does not walk to school./She doesn't walk to school.

For the above sentence, "She" is the subject, "does not" (or "doesn't") is the negative form, and "walk" is the base form of the verb (note that "walks" changes to "walk").

Verb to do

I do my homework in the morning. -> I do not do my homework in the morning./I don't do my homework in the morning.
He does homework in the evening. -> He does not do homework in the evening./He doesn't do homework in the evening.

In the above sentence, the verb "does" changes to its base form "do".

Verb to have

The base form of the verb has/have is "have". To form negative sentences with has/have, use do not/does not, followed by the verb "have".

They have a swimming pool at home. -> They do not have a swimming pool at home./They don't have a swimming pool at home.
He has a swimming pool at home. -> He does not have a swimming pool at home./He doesn't have a swimming pool at home.

Verb to be

When forming negative sentences with the verb "to be" (am, is, are), you simply add "not" directly after the verb. No additional auxiliary verb is needed.

I am a student. -> I am not a student.
You are a boy. -> You are not a boy.
He is kind. -> He is not kind.
