Present Simple - Present Progressive



Present Simple 


The simple present expresses an action in the present taking place once, never or several times. It is also used for actions that take place one after another and for actions that are set by a timetable or schedule. The simple present also expresses facts in the present.


Remember

  • In positive we use two conjugations. One is the simple form and the other is the “s” form (play/plays).
  • In negative sentences we use the auxiliaries don’t and doesn’t and the verb is ALWAYS in the simple form. (She doesn’t work).
  • In the question form we use auxiliaries do and does and also the verb goes in the simple form. The subject goes in between the auxiliary and the verb. (Do you work here?).


Examples

·       play tennis.
·       She does not play tennis.
·       Does he play tennis?
·       The train leaves every morning at 8 AM.
·       The train does not leave at 9 AM.
·       When does the train usually leave?
·       She always forgets her purse.
·       He never forgets his wallet.
·       Every twelve months, the Earth circles the Sun.
·       Does the Sun circle the Earth?





Present Progressive


The present progressive is used for actions going on in the moment of speaking and for actions taking place only for a short period of time. It is also used to express development and actions that are arranged for the near future.


Remember

  • When we construct the present continuous we use the verb to be. Therefore we DO NOT USE auxiliaries do, does, don’t or doesn’t.
  • Use the  “ing” form after the verb to be.

Examples


·       You are learning English now.
·       You are not swimming now.
·       Are you sleeping?
·       am sitting.
·       am not standing.
·       Is he sitting or standing?
·       They are reading their books.
·       They are not watching television.
·       What are you doing?
·       Why aren't you doing your homework?
