ESO3: Present Simple exercises

Here you have some exercises for practising the Present Simple structures. Revise the chart:

Affirmative	Negative	Interrogative
I go	I don't go	Do I go ?
You go	You don't go	Do you go ?
He goes	He doesn't go	Does he go ?
She goes	She doesn't go	Does she go ?
It goes	It doesn't go	Does it go ?
We go	We don't go	Do we go ?
You go	You don't go	Do you go ?
They go	They don't go	Do they go ?

We usually find it with epressions such as: often - generally - usually - always - never
every day - every week - every month - every year - sometimes
Remember we use it for habitual actions, universal truths, and 'permanent' situations, for example:

a) I usually go to school by bus. (Habitual action)
b) Water boils at 100ºC. (Universal truth)
c) I live in London.

Structure: subject + verb (base form)

I play football.
You play tennis.
We study here.
They work there.

LOOK! The alarm sounds in the 3rd person singular:

Affirmative: He PLAYS football.
Negative: He DOESN'T play football.
Question: DOES he play football?

Notice that we in the negative, questions, or after modal verbs (can, must...) we don't use the -s at the end:

He doesn't plays.
He doesn't play.

She can plays tennis.
She can play tennis.
