Use the Present Simple tense (“I go”, “He goes” etc) to talk about facts, things that are always true, or for routines and habits.
In England it often snows in winter. (a fact)
I live in London (true – I don't change my house every day)
John eats cereal for breakfast (routine or habit)
How to form the Present Simple
Use the same verb ending as the infinitive form for I, you, we and they. For he, she or it, add s or es or ies.
I play tennis
You play tennis
He / She plays tennis
We play tennis
They play tennis
Add es for verbs that end -ss, -sh, -ch, -tch:
I kiss / He kisses
I wish / She wishes
I match / It matches
I march / She marches
I study / She studies (the y changes to ies for verbs that end in 'consonant + y')
In the present simple of all verbs (except the verb to be and other modal verbs) you need an auxiliary to form negatives and questions. The auxiliary is do / does (for questions) and don't / doesn't for negatives.
Negative form of the Present Simple
To form the negative, use the auxiliary don't (for I, you, we, they) and doesn't (for he, she, it).
Then follow the auxiliary with the infinitive form of the verb.
I don't live here
You don't live here
She doesn't live here
We don't live here
They don't live here
In all the above, live is the infinitive form.
To form the question, use do / does as the auxiliary. Use do for I, you, we, they; and does for he, she, it.
Here is the word order for questions in the present simple:
Question word (optional) – auxiliary – subject – verb
Where do you live?
What does he do?
What does this computer program do?
Why do they argue all the time?
Do you like tennis? (There is no question word "why", "what", "where" in this question, so the question starts with the auxiliary "do".)
The verb that comes after the subject is the infinitive form.
You can answer a "do you" type question with a short answer. Use the auxiliary do / don't; or does / doesn't in your reply - NOT the infinitive.
Do I sign here? Yes, you do / No you don't.
Do you work here? Yes I do / No I don't.
Does she speak Spanish? Yes she does / No she doesn't.
Do we take this train? Yes, we do / No we don't.
Do they do their homework? Yes they do / No they don't.
