Grammar explanation
Time up to a point in the past
We use the past perfect simple (had + past participle) to talk about time up to a certain point in the past.
She'd published her first poem by the time she was eight.
We'd finished all the water before we were halfway up the mountain.
Had the parcel arrived when you called yesterday?
Past perfect for the earlier of two past actions
We can use the past perfect to show the order of two past events. The past perfect shows the earlier action and the past simple shows the later action.
When the police arrived, the thief had escaped.
It doesn't matter in which order we say the two events. The following sentence has the same meaning.
The thief had escaped when the police arrived.
Note that if there's only a single event, we don't use the past perfect, even if it happened a long time ago.
The Romans spoke Latin. (NOT
The Romans had spoken Latin.)
Past perfect with before
We can also use the past perfect followed by before to show that an action was not done or was incomplete when the past simple action happened.
They left before I'd spoken to them.
Sadly, the author died before he'd finished the series.
Adverbs
We often use the adverbs already (= 'before the specified time'), still (= as previously), just (= 'a very short time before the specified time'), ever (= 'at any time before the specified time') or never (= 'at no time before the specified time') with the past perfect.
I called his office but he'd already left.
It still hadn't rained at the beginning of May.
I went to visit her when she'd just moved to Berlin.
It was the most beautiful photo I'd ever seen.
Had you ever visited London when you moved there?
I'd never met anyone from California before I met Jim.

Hello Giudg1,
Yes, that is perfectly fine, grammatically.

Hello kingsonselvaraj,
Neither is correct. The phrase 'when you were young' tells us that the person is not young now, so the question is about a finished time period. The past simple is the best option:
The present perfect would be used if we were asking about the person's whole life, not just 'when you were young'.
We have no context for the sentence and no other time point for reference so there is no reason to use a past perfect.

Hello mara,
We can use the past perfect after 'before' when the action started before a certain time in the past, but was not completed.
In your example, the action of eating began before the person left the table. The use of the verb 'finish' is a little confusing, but in the context of eating we think of 'finishing a meal' as a process, not as a single momentary action.
Here is another example:
The guests arrived before I had finished preparing dinner.
My preparation began before they arrived, but was not finished.

Hello Dmevko,
The past simple is used for sequential actions, so it is fine to say he did this after we did that.
The past perfect makes clear a connection between two actions in the past. We use the past perfect, for example, when one action is the result of another, or is changed or influenced by another. The past perfect would not be wrong in your example, but there would need to be a reason to emphasise the relationship between the two actions beyond simple chronological sequence.

Hello Dmevko,
The present perfect describes actions occuring within an unfinished time period, but the action itself may be finished. For example, I use the present perfect in this sentence because the day has not ended yet:
Here, I've finished the book and there is a result (I can tell you about it) but the time period (today) has not finished.
I use the present perfect continuous if I want to suggest that the action itself is not finished. For example:
Here, the book hasn't been finished.

Hell Elysium,
We use the past perfect to refer to a time before another time in the past when there is some connection between the two (cause, influence etc). In other words, the past perfect does not exist in isolation, but always references another action or state, whether explicitly stated or implicit.
In your example it is hard to say why the author used the past perfect because we do not see the whole context in which the sentence is used. This means that we do not know what the connection is between being part of the seminar and another, later, action. It could be that Susan Calvin had been part of... and so was well prepared to do something else, but we cannot see this from the sentence in isolation.

Hello Kingson,
The sentence is not correct, I'm afraid. We do not use the present perfect (have seen) with a finished past time reference (when I visited). You need two past simple tenses here:
We would use the present perfect if the time reference is unfinished. For example, you could refer to your whole life up to now:

Hello kingsonselvaraj,
The problem with the sentence is that the phrase 'when I visited Vietnam' provides a finished time reference and so it cannot be used with the present perfect. The present perfect refers to an unfinished time, not a finished time. If you are no longer in Vietnam then that time period is complete and is not consistent with the present perfect.

Hello kingsonselvaraj,
The sentence 'My friend got married to the girl who has been working here in this office"(the girl is still working in the same office' is fine, because the present perfect phrase does not provide a time reference for the past simple action, but simply provides more information about the girl.
As an aside, I would say that the sentence is a little odd and the present perfect does not seem to add any information. A more natural way to phrase it would be to use the present simple (permanent work) or continuous (temporary): 'My friend got married to the girl is working/works here in this office"(the girl is still working in the same office.'

Hello Kingston,
That is correct. Well done!
The past tense gives us information about the book. Grammtically speaking, it is a restrictive or defining relative clause and has an adverbial function. It does not provide a time reference for the verb in the main clause.

Hello corflz
Both forms are possible, but the past simple form is probably better in more contexts than the past continuous form.

Hello kingson
It would be strange to say it that way; 'was working' would be the best form for most situations.

Hello Englishlearner123
Yes, that sentence is perfectly natural and correct. In this case, the continuous form is describing the background situation (which is a common usage of the continuous aspect) and the simple form is clarifying the relative sequence of events.

Hello Aniyanmon
We're happy to help you, but please remember two important things: 1) we ask that you try to ask your question on a relevant page and 2) we don't promise to explain grammar from other sources.
It's easy to find a page on modal verbs or modals with 'have', for example.

Hello Coffin Dodger
You can use the past perfect like that. People often use the past simple instead of the past perfect when that is possible. That is the case here, i.e. you could use the past simple in place of the past perfect in all of those verbs.
If you had a different questions, please let us know.

Hello again Aniyanmon
Does he still want to be an actor now, i.e. at the time you say this sentence? If so, only 2 is correct.
I'd suggest avoiding the past simple in the main clause of a sentence that has a 'since' clause, as it's usually not correct. If you were speaking about a person who no longer wants to be an actor, but did want to be one at one point in his life, then I'd suggest something like 'He wanted to be an actor from his teenage years until he finished university' (for example).
You might be interested in reading through the 'Since' page in the Cambridge Dictionary's Grammar section.

Hello Aniyanmon
'some time' is quite a vague expression -- it could mean for a few days, a few weeks, a few months or even longer. The context, including the person who says it, would in theory help you understand how long.

Hello Zhao
I'd suggest you take a look at our Perfect aspect page, where the meaning of the perfect aspect in general is explained and there are detailed explanations of both the present perfect and past perfect.
Your first two sentences are grammatically correct, but in the third one it's not correct to say 'enjoy' (in the present simple tense) with the time expression 'since'.
All the best

Hello Aniyanmon
Neither one clearly expresses what you explain. I would probably just say what you said in your explanation, but you could also say something like 'I am now a fan of Tyson Fury' or 'I have become a fan after that fight'.
Hope that helps.
Best wishes
