And now we're revising some verbal tenses:

PRESENT SIMPLE: I eat apples / I don't eat apples / Do you eat apples?
SUBJECT + (AUXILIAR) + VERB + COMPLEMENTS
Note: For the negative form of the PRESENT SIMPLE we use the auxiliar "do" in its negative form "don't" (for I, you, we, they) or "doesn't" (for he, she). The same thing happens with the question form, but instead of using the negative form, we use the positive (do, does) BEFORE the subject.

PRESENT CONTINUOUS: I am eating apples / I am not eating apples / Are you eating apples?
SUBJECT + VERB TO BE + VERB -ing + COMPLEMENTS


We use the PRESENT SIMPLE to talk about simple facts, wirhout giving any information about time.
Example: when I say "I eat apples" I am not saying WHEN I eat them, just that I eat them.

We use the PRESENT CONTINUOUS to talk about things that are happening in the moment you're talking.
Example: when I say "I am eating apples" I'm telling you that I'm eating apples RIGHT NOW.


IN THE QUESTION FORM OF ANY TENSE WE ALWAYS PLACE THE AUXILIAR BEFORE THE MAIN VERB!!
