In English, the base form of the verb is its simple form.
Examples of base forms are as follows: "play", "cook", "stay",
"work", "make", "be", "do". Notice that there is no change in
this form: no "ing", "s", or "ed". Use the base form after
modals (will, can, must, might, should, would, may). Also,
use the base form in sentences with do, does, and did.
In English, the infinitive is always "to+verb". Examples of
infinitives are as follows: "to play", "to cook", "to stay",
"to work", "to make", "to be", "to do". Use the infinitive after
many first verbs, but not modals. First verbs that are followed by
infinitives are: want, like, be going, have, ought, know how,
plan, forget, remember, need, decide.
In the following sentences, supply a base form or an
infinitive in the blank. You will find the answer in the
drop down menu.

Welcome to Basic English Grammar. This website is for beginning students of English as a Second Language. It's also helpful for Intermediate students who want to review. This is good typing practice, also. You won't find simple blank fill exercises. Instead, you'll write an entire sentence. It's better practice for you than clicking an answer or typing a single word. I hope you enjoy your time spent here learning or reviewing your Basic English.
