Four Present Tenses in English

 In English, there are four present tenses: simple present, present continuous, present perfect, and present perfect continuous.

Here's a chart showing the differences and meanings of each tense:

Tense	Form	Example	Use
Simple present	Subject + base form of verb	I walk to work every day.	Repeated actions, general truths/facts, and permanent situations.
Present continuous	Subject + "to be" verb + present participle (-ing)	I am walking to work right now.	Actions happening now or around now (temporary situations).
Present perfect	Subject + "have/has" + past participle	I have walked to work many times.	Actions that started in the past and continue until now (unfinished time period) or past actions with a present result.
Present perfect continuous	Subject + "have/has been" + present participle (-ing)	I have been walking to work a lot lately.	Actions that started in the past and continue until now (unfinished time period) or past actions with a present result, with a focus on the duration of the action.

And here are some exercises to practice using these present tenses:

1. Complete the sentences with the correct present tense:

a. I ____________ to music every day. (simple present) b. She ____________ on her homework right now. (present continuous) c. They ____________ their friends for ten years. (present perfect) d.
