Present simple tense

Rule:

The verb doesn't change when we use those pronouns: I , you, We and they 

Eg: I teach English

You watch TV.

We go the the zoo.

They play football.

For the 2nd person singular ( He and She) there are some changes:

 In  regular verbs  we add s at the end of the verb.eg: He plays tennis .

She needs help.

- In verbs ending with s, ss, sh, o and x we add es at the end of the verb.

Eg. : -  She washes the dishes.

The boy misses the bus.

In verbs ending with y after a consonant (opposite of vowel)  the y changes to i and add es.

Eg.:  The bird flies in the sky.

When do we use present simple?

- To talk about general facts: The sun rises in the east.

- to express habits or costoms: I go to school everyday.
