1. We use the Present Simple for:
Regular habits and daily routines.
Facts, things in general.
Permanent or long-lasting situationes
Timetables and schedules.
2. It is used with adverbs like:
Always
Often
Usually
Sometimes
Never
1. To form the Present Simple we add –s to the infinitive of the verb in the 3rd person singular (he, she, it)
2. But when the verb ends in:
a) –o, -ss, -sh, -ch, we add –es
b) a consonant followed by –y, the –y changes into –ie and we add -s
c) a vowel followed by –y we just add -s
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.
For example:
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
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”.)
