GRAMÁTICA : Simple Present Tense #1, by Dennis Oliver

Simple Present Tense #1, by Dennis Oliver
Verb Tenses: Simple Present (#1)
  Verb tenses are changes made in the form of verbs.
These changes are important for meaning because
they are "signals" about time, whether something is
a continuing action, and other information.
One important English verb tense is the simple present.
This is actually not a very good name because its
meaning is not exactly simple and the time for which
it is used is not exactly present.
In order to understand simple present tense better,
we'll look first at its form.
   
 

The Simple Present Tense: Form
   
  There are different simple present tense forms for be
and for other verbs.

BE
(affirmative)
I amyou arehe isshe isit iswe areyou are

Other Verbs
(affirmative)
I base formyou base formhe / S / formshe / S / formit / S / formwe base formthey base form
  _______________________________________________
 
There are also differences when be and other verbs
are negative in simple present tense:

BE
(negative)
I am notyouare nothe is notshe is notit is notwe are notthey are not

Note:

Contractions are often used for not, am not, is not,
and
are not:
are not ---> aren't
is not ---> isn't
I am not ---> I'm not
you are not---> you're not
he is not---> he's not
she is not---> she's not
it is not---> it's not
we are not---> we aren't
they are not---> they aren't

Other Verbs
(negative)

you
do not + base form
he
does not + base form
she
does not + base form
it
does not + base form
we

Note:
Contractions are often used for do not and does not:
I do not ---> I don't
you
do not ---> you don't
he
does not ---> he doesn't
she
does not ---> she doesn't
it
does not ---> it doesn't
we

They are no contractions for do or does in standard
written English.

Special Notes:


1.
  There is no acceptable contraction for am not
in standard English. However, you will sometimes
hear people say *ain't--which is considered
unacceptable and "uneducated." Some people
also use *ain't for you, he, she, it, and they--
not only for I.
     
2.
  Final / S / has three different spellings. Many
verbs simply add -s or -es. Verbs that end in
a consonant + y change the y to i and then
add -es.
