The formula for making a simple present verb negative is do/does + not + [root form of verb]. You can also use the contraction don’t or doesn’t instead of do not or does not.
Examples:
Pauline does not want to share the pie.
She doesn’t think there is enough to go around.
Her friends do not agree.
I don’t want pie anyway.
To make the verb to be negative, the formula is [to be] + not.
I am not a pie lover, but Pauline sure is.
You aren’t ready for such delicious pie.
Compare the positive and negative sentences below.
Do not add an “-s” or “-es” to the verb after “do not” or “does not”.
Title: Choosing Dessert
Characters:
Scene: Mia and Sam are at an ice cream shop, trying to decide what to order.
Mia: (contemplative) Sam, I don’t like chocolate ice cream. It’s too rich for me.
Sam: (surprised) Really, Mia? I love chocolate ice cream. What flavors do you like then?
Mia: (thoughtful) I do like vanilla and strawberry. They’re not as intense as chocolate.
Sam: (understanding) I see. Well, I don’t like fruit-flavored ice creams. They’re too sweet for my taste.
Mia: (nodding) That’s fair, Sam. We all have different preferences. How about we each get our favorite flavor today?
Sam: (agreeable) Sounds like a plan, Mia. I’ll have chocolate, and you can have strawberry.
Mia: (smiling) Perfect! I’m glad we can both get what we like.
