A verb tells about an action while a tense tells about the time. Thus, the tense of a verb tells us when, in time, an action occurred. There are three simple verb tenses:
The simple present tense indicates an action that is happening now.
The dog barks at the mailman.
I clean my room.
I fold the laundry.
She mops the floor.
I always listen to music.
I work very hard.
All these sentences are in the present tense and in each, the verb is underlined.
Also, sentences in the present tense use the base form of the verb.
We also use the present tense when:
1. We talk about something that is permanent.
2. Or, when we talk about how frequently something happens.
However, if we are using the pronouns he, she, or it, then we add an "s" to the end of a present tense verb.
1. She asks for help.
2. He mows the lawn.
3. It seems correct.
