2. What Are โDoโ and โDoesโ?
Do and does are auxiliary verbs (helping verbs). They help us form:
Questions in the present simple
Negative sentences in the present simple
Emphasis
They do NOT show action. The action is always in the main verb.
โ๏ธ DO โ plural subjects + โIโ and โyouโ
โ๏ธ DOES โ singular subjects (he, she, it)3. When to Use โDoโ
We use do with:
I
You
We
They
This is one of the most important grammar rules in English.
โ๏ธ Examples in Affirmative Sentences:
I do my homework every afternoon.
You do amazing work.
We do exercises in the morning.
They do their best to study English.
These sentences show action, not the auxiliary use.
4. When to Use โDoesโ
We use does with:
He
She
It
โ๏ธ Examples in Affirmative Sentences:
He does his homework after dinner.
She does her hair every morning.
It does a good job cleaning the floor.
Again, these show action.
