There are two tenses in English – past and present.
The present tenses in English are used:
   to talk about the present
   to talk about the future
   to talk about the past when we are telling a story in spoken English or when we are
    summarising a book, film, play etc.
    There are four present tense forms in English:
               Tense                      Form
    Present simple:              I work
    Present continuous:          I am working
    Present perfect:             I have worked
    Present perfect continuous: I have been working
    We use these forms:
   to talk about the present:
         He works at McDonald’s. He has worked there for three months now.
         He is working at McDonald’s. He has been working there for three months
         now.
         London is the capital of Britain.
   to talk about the future:
         The next train leaves this evening at 1700 hours.
         I’ll phone you when I get home.
         He’s meeting Peter in town this afternoon.
         I’ll come home as soon as I have finished work.
         You will be tired out after you have been working all night.
   We can use the present tenses to talk about the past ...
o   when we are telling a story:
    Well, it’s a lovely day and I’m just walking down the street when I see this funny guy
    walking towards me. Obviously he’s been drinking, because he’s moving from side to
    side …
o   when we are summarising something we have read, heard or seen:
    I love Ian Rankin’s novels. He writes about this detective called Rebus. Rebus lives in
    Edinburgh and he’s a brilliant detective, but he’s always getting into trouble. In one
    book, he gets suspended and they tell him to stop working on this case. But
    he takes no notice ….
    Romeo and Juliet is a violent play. After Romeo and Juliet have married in secret,
    Romeo is walking in Verona when Juliet’s cousin, Tybalt tries to provoke Romeo into a
    fight. Romeo refuses to fight and leaves, but his friend, Mercutio, is so angry that
    he fights Tybalt and is killed ….
    What Is the Present Tense? (with Examples)
    The present tense predominantly describes a current event or state of being.
    However, somewhat unusually, the present tense can also be used to
    describe past and future events (more on this below). For example:
      I jump in the lake every Saturday.
       (present event)
      I am happy.
       (present state of being)
      The meeting ends at 6 o'clock.
       (future event)
       (See "Uses" for Simple Present Tense in the table below.)
      A man walks into a bar. Ouch!
       (past event)
       (See "Uses" for Simple Present Tense in the table below.)
    The tense of a verb is determined by when the action took place. The three
    main tenses are:
      past tense
      present tense
      future tense
    Examples of the Types of Present Tense
The present tense is categorised further depending on whether the action is in
progress or completed. The four present tenses are:
