2. Uses

1. unfinished actions or states or habits that started in the past and continue to the present. Usually we use it to say ‘how long’ and we need ‘since’ or ‘for’. We often use stative verbs.

Examples

Thank you for reading this post, don't forget to subscribe!

I have been in this city since last year..
She’s lived in Morocco for three years.
I’ve known him for three years.

2. Life experience

Talking about actions or events you have done or you have never done before. Time is not important to be mentioned and the doer of the action needs to be alive now. We often use the words ‘ever’, ‘never’, yet ‘still’ here.

Examples:

Have you ever been to France?
Ahmed has already had a car.
Have you finished your homework?

3. With an unfinished time word (this month, this week, today). The period of time is still continuing.

Examples:

She has read the entire book this month.
She’s drunk three cups of coffee today.
I’ve already moved house twice this year!

4. It is also used to express an event that has occurred repeatedly from one point in the past up to the present time. The event may happen again

Examples:

She had had three tests so far this term.
The lawyer has sent him three letters so far.
I have met many people since I came here.

5. To talk about a recent action or event, even if there isn’t a clear result in the present. This is common when we want to introduce news and we often use the words ‘just / yet / already / recently’.

Examples:

He has just arrived.
The have cleaned the house recently. It is spotless.
The Mayor has announced a new plan for the railways.

Been Vs Gone
Look at the two examples below

I’ve been to Australia (in my life, but now I’m in Fance, where I live).
I have gone to Mexico (now I am in Mexico).
‘Since’ Vs ‘For’
Since

Since is used with a fixed time in the past or another action

Examples

We have been together since 2012. (fixed time which is 2012)
I’ve lived here since I was a child. (fixed time in the for of another action ” was”-
For

it is used to specify “period of time”
