The present simple takes the following forms:

Subject + the present simple form of the verb + (objects)

You may have noticed that when the subject is a plural noun, the present simple form of the verb is no different from the infinitive without to.

Children play in the garden. (NOT Children to play in the garden.)

The planets move around the sun. (NOT The planets to move around the sun.)

When the subject is a singular noun, the present simple form of the verb takes the marker –s.

The earth moves around the sun. (NOT The earth move around the sun.)

Alice writes stories for kids. (NOT Alice write stories for kids.)

Notes

Verbs in the simple present tense do not have the marker –s when the subject is I or you.
