Let’s review some of the things we’ve covered here in Grammar Basics so far.
When we use modal verbs (will, shall, might, may, can, could, must, should, would), we use what is called the base form, or dictionary form, of the verb:
will: John will wash the dishes.
shall: I shall call you later today.
might: It might rain tomorrow.
may: Tom may come to the party.
can: Bobby can write his name now.
could: We could go to the park.
must: You must stand up.
should: He should get a new car.
would: I would be quiet if I were you.
The base form / dictionary form is also used with do/does and did:
do/does:
Do you see John anywhere?
Does your dog have a leash?
The phone doesn’t work.did:
When did you come home last night?
I didn’t eat the cupcake.
We also use the base form / dictionary form after the infinitive marker to:
going to: I’m going to go to bed now.
have to: Tom has to do his homework after school.
want to: We want to build a sand castle.
would like to: I would like to have some tea, please.
used to: We used to play by the river when we were kids.
–ing is used for the continuous form:
am/is/are –ing:
Our school is putting on the play, The Diary of Anne Frank.
We are going on vacation next month.
I am taking a shower.was/were –ing:
I was sleeping when you called.
The boys were playing outside when Grandfather arrived.
