PRESENT SIMPLE
- Present Simple ( I do )
We use the present simple to talk about things in general. We are thinking only about the present. We use it to say that something happens all the time or repeatedly, or that something is true in general. It is not important whether the action is happening at the time of speaking.
a) Study this example situation:
Alex is a bus driver. But now he is asleep in bed.
So:
He is not driving a bus ( he is asleep)
But: He drives a bus.
b) This is the present simple tense:
he/she/it drives
they/we/I/you drive
c) We use do/does to make questions and negative sentences:
Do they/we/I/you work?
They/we/I/you don’t work
Does he/she/it work?
he/she/it doesn’t work
d) Adverbial of time:
- Everyday
- Every morning
- Twice a week
- etc.
- Present Continuous ( Progressive ) (I am doing)
We use the present continuous to talk about something which is happening at or around the time of speaking.
a) Study this explanation:
Tom is in her car. She is on her way to work.
She is driving to work
This means: She is driving now, at the time of speaking
We use the present continuous for a temporary situation:
That machine isn’t working. It broke down this morning.
I’m living with some friends until I can find a flat.
We use the present continuous when we talk about a period around the present.
For example: today, this season, etc.
You are working hard today
Jim is not playing tennis this season.
We use the present continuous when we talk about changing situations:
The population of the world is rising very fast. (not ‘rises’
Is your English getting better? (not “does … get’)
b) This the present continuous tense:
he/she/it is playing tennis
they/we/you are playing tennis
I am playing tennis
- Present Perfect (I have done)
a) Study this example situation:
Jim is looking for his key. He can’t find it.
He has lost his key.
“He has lost his key” means that he lost it a short time ago and he still hasn’t got it.
b) This is the present perfect tense:
they/we/I/you have (= they’ve etc.) lost
he/she/it has (= he’s etc.) lost
c) We use have/haven’t / has/hasn’t to make questions and negative sentences:
have they (etc.) lost?
They (etc.) haven’t lost
Has he (etc.) lost?
He hasn’t lost
- Present Perfect Continuous
We use present perfect continuous when we talk about an action (quite a long action) which began in the past and has recently stopped or just stopped.
a) Study this example situation:
Is it raining?
No, it is not but the ground is wet
It has been raining.
b) This is the present perfect continuous tense:
they/we/I/you have (= they’ve etc.) been doing
he/she/it has (= he’s etc.) been doing
