The bare infinitive in the present simple – with exercise

bare infinitive present simpleIn the affirmative present simple, the forms for he/she/it use different conjugation to the bare infinitive (the “third person S” rule, for regular verbs). Otherwise you may not notice a difference, for example: I like cheese (present simple form of to like) vs I do like cheese (bare infinitive form of to like). This means that if you confuse a present simple verb with a bare infinitive, or the other way round, you will only notice a mistake in its form when the subject is he/she/it. The following exercise tests the understanding of when a different conjugation is necessary, with answers below.
