The Simple Present tense
The structure of the negative structure is formed by adding the auxiliaries do or does plus the negation not
Do + not —> don’t
Does + not —> doesn’t
These auxiliaries are used TO HELP you. When you use the auxiliary the verb is always in its simple.
Remember:
In positive we had 2 conjugations for every verb (not to be)
- play/plays , work/works, study/studies, watch/watches, etc…
The conjugation is simple: HE / SHE / IT —- with the “s” form and I / WE / YOU / THEY —- simple form
Examples:
My brother works for IBM.
My parents live in Paris.
He / she / it + doesn’t + verb (simple form)
I / We / You / They + don’t + verb (simple form)
