had been working / has worked

[Gorkem Atay]

1. ''He had been working for more than 8 hours.''

2. ''Two days ago, he has worked for more than 8 hours.''


Firstly, what is the difference between them?

Secondly, I want to know whether the first one is useful in general and it is natural.


Thanks a lot.

Hello, Gorkem Atay.:-D
Well, your second sentence should be in the past tense:
'Two days ago, he worked for more than eight hours.'

Your first sentence, which is in the past perfect progressive/continuous tense, is grammatically correct.
However, you need some context to use it.

I hope my response will be of some help to you.

Hello tzfujimino,

''He is still exhausted because he has worked for more than 12 hours yesterday.''
What about this sentence, can I use perfect tense? Because his tiring work effect is still continuing and it is defined in the sentence.

And, what kind of context does my first sentence need, would you mind giving me an example please?


Thanks,

Thanks,

You should try to put sentence #1 into a context you think is appropriate, the we will comment on it. In your new sentence, the perfect tense is inappropriate, we know that his exhaustion is continuing because you have said "He is still ehausted..."

For the sentence #2

(the person A knows that the person B works in a very very tiring work six days a week)

A: Why don't you come with us and exercise now?
B: I can not, I have worked extra long time yesterday.

Am I right now?

No, whenever you include a time in the past ("yesterday"), you do not use the present perfect.
