Simple Present Tense
The simple present tense uses the same verb form as the root form of the verb. We use the simple present tense in the following conditions:
For activities that we do daily -regularly or habitually
We use this tense with a few adverbs to indicate something that happens rarely
To express thoughts, feelings, opinions and beliefs
To show a fact or something that is always true
For a planned action or an event that will happen in the future
We use it in news, reported speech such as in sports commentaries, a narration of books and stories etc
For schedules, plans and programs
