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 after before
We can also use before + past perfect 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?

Hello Aniyanmon
In most situations, the use of the present perfect here indicates that he is still a policeman at the moment of speaking. There are situations where this may not be true, but that is dependent on the context.

Hello Aniyanmon,
Both sentences are correct. Is there is a question about presence or lack of it; Do you have identifies ownership. For example, if I say there is a car outside my house then it is probably not my car, but if I say I have a car outside my house then the listener will understand that I am the owner.

Hello Aniyanmon
Sentence 1 uses a second conditional structure and talks about an imaginary situation in the present or future. Sentence 2 uses a third conditional structure and talks about an imaginary past situation, i.e. a situation in the past that did not happen, but could have happened if the condition had been met.
You can see more about conditionals on our Conditionals 1 and 2 pages.
