Present Simple (1)

1.- We form the Present Simple like this:

Positive

Singular I Know
you know
she/he/ it knows

Plural we know
you know
they know


I know the answer.
She stars work at 9.30.


* We add -s after he/she/it:

I start --> he stars I live --> She lives

* If a verb ends in -ch, -o, -sh or -ss we add -es after he/she/it:

I watch --> he watches you do --> she does
they go --> it goes we wash --> she washes

*If a verb ends in a consonant (b, c, etc.) + y (e.g. study), we use -ies after he/she/it:

I study --> he studies I fly --> it flies

2.- Now look at these examples of the negative:

I don't like that music.
He doesn't listen to his teacher
