Present Perfect Continuous

Hello everyone,

I have been learning english since my childhood.
She has been driving her car for two hours.
He has not been doing anything since breakfast.
You have been painting a house.
We haven’t been eating l lot.

Have a nice night.

Just a couple of comments:

‘English’ is always written with a capital letter.

The better tense would usually be ‘He has not done anything since breakfast.’

“We haven’t been eating a lot” indicates a longer period of time than ‘We haven’t eaten a lot’.

English was just a typo, sorry.
Sometimes I don’t understand the difference between Present Perfect and Present Perfect Continuous. My bad.

I have been studying in college for three years. ( I guess the right preposition is ‘in’ not 'at) ( at university, in college)
Has she been smoking?
They have been talking for an hour.

What is wrong with the word ‘mistake’ these days? It’s a perfectly good word and has more sense than the ridiculous phrase ‘my bad’.

‘Bad’ was the first word that came into my mind. I feel some anger in the air. Did you get up on the wrong side of the bed?
By the way, have a nice day.

NO, to me the phrase ‘my bad’ is nonsensical. I was brought up when people said ‘My mistake’, which is correct.

I see.

Here are some new trying:

He has been repairing my car since Thursday.
I have been using a computer for three hours.
They have been gardening.
Have you been smoking?

“…some new tries” (some new attempts)

He has been repairing my car since Tuesday.
I have been using a computer for three hours.
These are okay as long as you mean that he is still repairing it/ you are still using it or you have stopped very, very recently.

The other two are fine.

I have been using the English language on my mobile phone for two years.

I’ve been waiting here for two hours.
How long has he been waiting here?
They have been cutting vegetables.
Haven’t you been learning English?
How long have she been crying?
I have been working here since 1996.
Since when has he been watching TV?
We have been playing football for hours.
I haven’t been drinking coffee for two weeks.

How long has she been crying?

he / she /it/ [/b]has[b]. You got it right in the sentences about watching TV and waiting here.
