Grammar explanation
We use the present perfect simple (have or has + past participle) to talk about past actions or states which are still connected to the present.
Unfinished time and states
We often use the present perfect to say what we've done in an unfinished time period, such as today, this week, this year, etc., and with expressions such as so far, until now, before, etc.
They've been on holiday twice this year.
We haven't had a lot of positive feedback so far.
I'm sure I've seen that film before.
We also use it to talk about life experiences, as our life is also an unfinished time period. We often use never in negative sentences and ever in questions.
I've worked for six different companies.
He's never won a gold medal.
Have you ever been to Australia?
We also use the present perfect to talk about unfinished states, especially with for, since and how long.
She's wanted to be a police officer since she was a child.
I haven't known him for very long.
How long have you had that phone?
Finished time and states
If we say when something happened, or we feel that that part of our life is finished, we use the past simple.
We visited Russia for the first time in 1992.
I went to three different primary schools.
Before she retired, she worked in several different countries.
We also use the past simple for finished states.
We knew all our neighbours when we were children.
I didn't like bananas for a really long time. Now I love them!
Past actions with a result in the present
We can use the present perfect to talk about a past action that has a result in the present.
He's broken his leg so he can't go on holiday.
There's been an accident on the main road, so let's take a different route.
They haven't called me, so I don't think they need me today.
Again, if we say when it happened, we use the past simple.
He broke his leg last week so he can't go on holiday.
However, we often use the present perfect with words like just, recently, already, yet and still.
We've recently started going to the gym.
She's already finished season one and now she's watching season two.

Hi Kapil Kabir,
Interesting question! Yes, those sentences are grammatically correct. The meanings are similar to We'll need ten extra pounds and I've had three busy days.
Why is the article used? It shows that the speaker is thinking of 'ten pounds' not as ten individual units, but as one single unit, all together. That's why the indefinite article is used here - the basic structure is 'We'll need an extra (something)' , and the 'something' is 'ten pounds' (as one unit). Similarly, in sentence 2, the speaker is thinking of 'three days' as a single unit of time.
This structure is often used if the speaker wants to add an adjective to describe that unit. Here are some more examples: The journey was a long three hours / There were an incredible five hundred comments on the video. The structure is article + adjective + number + noun.
Thanks for your question! Please try to post questions on pages relevant to the question. This question would have been good on our Articles page, for example. Thanks :)

Hello Kapil Kabir,
You might want to refer to our Conditionals 1 and 2 pages, where you can see the structures that are taught in most textbooks and where we mention the mixed conditional. Often English learners get the impression that these structures are the only possible ones, but this is not the case.
I find the sentence that you cite a little confusing. The first part ('if this were to be the case') suggests an unreal present situation, but then it goes on ('this conflict would have long been over') to refer to an unreal past situation that seems to be dependent on the present situation. Perhaps I've misunderstood it, but this doesn't make sense to me. Perhaps I'm missing something here, but that's how I see the sentence here in isolation.
Both 3 and 4 are correct: 'if this were to be the case' is very similar in meaning to 'if this were the case'; both refer to an unreal condition in a hypothetical present or future time. The first form is more formal and makes it seem that this situation is even more unlikely that the second one, but other than that they mean the same thing.
Hope this helps you.
All the best,

Hi Gulnara_BC,
Good question! Yes, it is correct. The present perfect shows that the time period is unfinished - i.e., 2021 is not over yet, and it is possible for those numbers to change before 2021 ends. The meaning is something like 'so far in 2021'.
It's also possible to use the past simple, as you suggest: 30 workers were seriously injured and 4 workers died. We can also understand those particular accidents as completed events.
Somebody might choose to use the present perfect if they want to, perhaps, suggest to the reader that the situation might get worse before the year ends. Alternatively, somebody might use the past simple if they want to focus on the details of those particular accidents, without considering what may happen in future.
Does that make sense?

Hello Kapil Kabir,
'They never go there' is what we call the present simple; it is not the present perfect, which would be 'They have never gone there'.
'They never go there' does not necessarily mean they have never gone there; it can mean that they don't go there now, but it's possible they went there in the past.
The only way to know which meaning is intended is to examine the context or ask the person what exactly they mean.
All the best,
Kirk
