Today's lesson - Class note
1. Verb Infinitive (Base Form)
What is it?
A base verb is the clean verb with no -s / -ed / -ing:
go, eat, play, be, have
We use the base verb in three common places:
Rule 1 — after to + base verb
-
I want to play.
-
She likes to read.
-
We need to go now.
✗ I want to plays → ✓ I want to play
Rule 2 — after modal verbs + base verb
(can / could / will / would / shall / should / may / might)
-
I can swim.
-
He will come later.
-
We should do our homework.
-
She may be late.
✗ She can to dance → ✓ She can dance
✗ He will goes → ✓ He will go
Rule 3 — Negative with do/does/did not + base verb
-
I do not (don’t) like milk.
-
He does not (doesn’t) eat meat.
-
They did not (didn’t) watch the movie.
✗ He doesn’t likes pizza → ✓ He doesn’t like pizza
✗ We didn’t watched it → ✓ We didn’t watch it
Remember
-
After to, after a modal, and after do/does/did not → use the base verb.
-
Base verb = no -s, no -ed, no -ing.
Compare the past and the present:
Long ago, the Abenaki lived in wigwams. Today they live in modern houses.
Long ago, the Abenaki were farmers, hunters and fishers. Today they dress and work like other Americans.
