Recognize main verbs, auxiliaries, and the base, -s, -ing, past, and past participle forms.
THE VERB-SHAPE RULE
No helper:
person/thing + MAIN VERB carries the grammar
She works from home.
└─ main verb gets -s
With a helper (auxiliary = helping verb):
person/thing + HELPER + main verb shape
│
├─ be → -ing
│ They are working today.
│
├─ have → past participle
│ We have worked together before.
│
└─ do / does / did / modal → base verb
Does he drive?
He can drive.
Do not mark twice:
She doesn't likes coffee. ✗
She doesn't like coffee. ✓
When a helper is present, put the grammar on the helper and use the form it asks for on the main verb.
