(英文) 我想問下"這是講述一個警察上班的一天"應該點講?

A day's life : 一天的生活
A day's life of a policeman on duty : 當值警察一天的生活

"這是講述一個警察上班的一天"應該點講?

It talks about a day's life of a policeman on duty.

=========================================================
順便問問:
I think books or films concern for police and mafia is popular in HK.
↑請問gramma岩唔岩?

"concern for police .. " should be "concerning about police .."
"is popular" should be "are popular"
... or better still ...
I think books or films about police and mafia are popular in HK.

It's talk about the policeman on duty in a day.這是講述一個警察初次上班的第一天。
更正英文:It's talking about the first day when the policeman attends his office.

I think books or films concern for police and mafia is popular in HK.
更正英文: I think that all books or films concerning the actions of police and mafia are being considered popular in Hong Kong.
