Present Simple.
Present simple is the tense more easy and important in English.
The basic structure is:
Subject - verb - complement.
I watch T.v.
You walk in the street
We eat pizza.
They run in the park.
If the "subject" is third person add to "-s" in the verb.
Example:
He learns English.
She talks with Carmen.
Horse runs very fast
But if the verb ends in "-o","-sh", "-ch" , "-ss", "-x" , "-z", "-y" add to "-es".
Example:
He goes
He wishes
He reaches
He expresses
He fixes
He kisses
He buzzes
But if the verb ends in "-y" when isn't preceded by a vowel add to "-ies".
Example:
He occupies
He studies
But if the verb ends in "-y" when preceded by a vowel add to "-s".
Example:
He buys
Present simple (negative)
The negative structure is.
Subject - do/does - not - verb (basic form) - complement.
Note: We use DOES when we talk in the third person.
Example:
I do not sing in a concert.
He does not sing in a concert.
They do not play soccer.
Note: We can use contraction for "do not" = "don't" and for "does not" = "doesn't" for informal mode.

Note: We use DOES when we talk in the third person.
