Verbs and Their Tenses

    A verb changes form to show the time of the action it describes. These different forms are the tenses of the verb. The present, past, and future tenses are the simple tenses.
  • The rose looks pretty. The roses look pretty. (present)
  • They looked even nicer yesterday. (past)
  • They will look dry and wilted in a few days. (future)
    The present tense indicates an action that happens now or on a regular basis, such as "The sun rises every day." Most present tense verbs follow the pattern shown below for look. Has and be are important exceptions.
  • look: I look, you look, she looks, we look, they look
  • has: I have, you have, he has, we have, they have
  • be: I am, you are, it is, we are, they are
    The past tense indicates an action that occurred in the past. It is the second principal part of a verb. The past tense of regular verbs are formed by adding -ed or -d to the present form. If you don't know the past tense of an irregular verb, check a dictionary.
    The future tense indicates an action that has not yet happened but will occur in the future. It is formed by using a helping verb such as will or shall with the present form.
