    when to use have or has?

    i always wondered when do i have to use "have" in a sentence
    for example " i ate the apple " and " i have eaten the apple "

    what is wrong with these 2 sentences?

    i just want to know when it is ok to use have and when it is not.

    thats one thing

    Also, i wanna make sure that i got this correct. we use "had" we are talking about the past right ? for example " he asked me if i had done my homework".
    and have if we are talking about something that is happening or happened a while ago. is that right ?

    I ate the apple [yesterday]. Rupture with the present because it happened yesterday and not today
    I have eaten the apple [today]. No rupture with now because it is still today

    Not a teacher at all, anyway

    The short answer: nothing is wrong with those two sentences except you should capitalise "I"

    Longer answer:
    Past, present and future are time concepts which have their own tense forms.

    Present tense forms:
    I eat the apple, he eats the apple
    I am eating the apple, he is eating the apple

    Past tense forms:
    I ate the apple, he ate the apple
    I have eaten the apple, he has eaten the apple
    I had eaten teh apple, he had eaten the apple

    Future tense forms:
    (Your homework here)

    Conditional forms:
    (Your homework here)

    philadelphia good, you are getting there, but note, you are in fact alerting us to the second way of locating activity in time, this is called "aspect". But don't get the two confused, they should work together logically.

    Take a look at this sentence:

    "Philadelphia eats the apple tomorrow" (e.g. your chef is discussing your menu for tomorrow with somebody)

    Present tense form "eats"
    Future time concept "tomorrow" ("future" aspect)

    Is the time concepts chronologically logical?
    What would make it illogical? and why?
