Present Tenses

The present tense is the tense (that is, the form of the verb) that may be used to express :

  • action at the present
  • a state of being;
  • an occurrence in the (very) near future;
  • or

  • an action that occurred in the past and continues up to the present.
  • 1. present simple, which is used to describe both habits and or routines (I eat breakfast every morning at 6:30. I go to work every day), and general facts or the truth (The earth revolves around the sun);
    (+) S + V1s/es + O
    (-) S + do/does + not + V1
    (?) Do/does + S + V1

    2. present progressive or present continuous, which is used to describe events happening now, e.g. I am reading this wiki article, and I am thinking about editing it;
    (+) S + tobe+ V1 + ing + O
    (-) S + tobe + not + V1 + ing + O
    (?) tobe + S + Ving

    tobe : is/am/are

    3. present perfect progressive, which is used to describe events or actions that have begun at some point in the past and continue through the present, e.g. I have been reading this article for some time now.
