Tenses

1. Read the following sentences carefully: 
   • Birds fly in the air. 
   • My brother flew to England last week. 
   • I shall fly a kite on Sunday.
     In the first sentence the Verb ‘fly’ refers to the Present time, in the second sentence the Verb ‘flew’ refers to the action in the Past, while the Verb in the third sentence ‘shall fly’ refers to the Future.
2. The Tense of a Verb shows the time when an action takes place.
   There are three Tenses:
   • Present Tense
   • Past Tense
   • Future Tense
3. In order to show at what stage an action is, each of the three tenses has been sub-divided into four heads.
