Simple Present Tense

How do we make the Simple Present Tense?
subject + auxiliary verb + main verb
do base

There are three important exceptions:

For positive sentences, we do not normally use the auxiliary.
For the 3rd person singular (he, she, it), we add s to the main verb or es to the auxiliary.
For the verb to be, we do not use an auxiliary, even for questions and negatives.
Look at these examples with the main verb like:

subject auxiliary verb main verb
+ I, you, we, they like coffee.
He, she, it likes coffee.
- I, you, we, they do not like coffee.
He, she, it does not like coffee.
? Do I, you, we, they like coffee?
Does he, she, it like coffee?

Look at these examples with the main verb be. Notice that there is no auxiliary:

subject main verb
+ I am French.
You, we, they are French.
He, she, it is French.
- I am not old.
You, we, they are not old.
He, she, it is not old.
? Am I late?
Are you, we, they late?
Is he, she, it late?

How do we use the Simple Present Tense?
We use the simple present tense when:

the action is general
the action happens all the time, or habitually, in the past, present and future
the action is not only happening now
the statement is always true
John drives a taxi.
past present future

--------------------------------------------------------------------------------

It is John's job to drive a taxi. He does it every day. Past, present and future.

Look at these examples:

I live in New York.
The Moon goes round the Earth.
John drives a taxi.
He does not drive a bus.
We do not work at night.
Do you play football?
Note that with the verb to be, we can also use the simple present tense for situations that are not general. We can use the simple present tense to talk about now. Look at these examples of the verb "to be" in the simple present tense—some of them are general, some of them are now:

Am I right?
Tara is not at home.
You are happy.
past present future

--------------------------------------------------------------------------------

The situation is now.
I am not fat.
Why are you so beautiful?
Ram is tall.
past present future

--------------------------------------------------------------------------------

The situation is general. Past, present and future.

Present continuous :
Use the continuous for something that is happening at or around the time of speaking .
The action is not finished .

( past ) ------------------ ( now ) ------------------------ ( future )
................................ I am doing.............................

e.g.
The water is ^boiling .
It is ^raining now .
She' s ^learning English .

Use the continuous for a temporary situation :
e.g.
I' m ^living with some friends until I find a flat .
You' re ^working hard today .

------------------------------------------------------------------

Present simlpe :
Use the simple for things in general or things that happen repeatedly .

( past ) -------------------- ( now ) --------------------- ( future )
<< --------------------------- I do ---------------------------- >>

e.g.
Water ^boils at 100 degrees celsius .
It doesn' t ^rain very much in summer .
I always ^go to bed before midnight .
Most people ^learn to swim when they are children .

Use the simple for a permanent situation :
e.g.
My parents ^live in London . They have lived there all their lives .
He ^works very hard most of the time .
