Tenses tell us when an action happened
·Simple tenses use the past form, the present form, and the present form with the helping verb will.
yesterday I walked home school
Tomorrow I will walk home from school
Perfect tenses
·Perfect tenses show when an action happened in relation to another action. The action in the past perfect began and ended before the event or time it is being related to. The action in the present perfect began in the past and continues up to the present or has ended by the present. The action in the future tense will be finished a particular point in the future.
·The perfect tenses use the helping verb to have (have/has, had) with the past participle of the verb. The verb to have changes to show the tense.
Yesterday I rode to school, but the day before I had walked to school
Most days I walk to school, but for the last two weeks I have walked to school
By the time I get to school tomorrow, I will have walked to school many times
