英文問題...好易但我覺得好難

這一直都很艱難係未 it has been tough? YES
i have been in love 係未我一直都戀愛緊 YES但有D怪
我以前曾經戀愛過: I was in love.



佢已經做左五年policeman了(現在都是)
He has been a policeman for 5 years.

ｑ１．
present perfect 可以講一直發生至今o既事，往往都會講埋發生左幾耐（如加上 always / for X years），所以：
這一直都很艱難：It has always（always 正是一直之意） been tough.
我一直都戀愛緊：I have always been in love.
我以前曾經戀愛過：呢句中文話雖係往事，但其實同現時有關，所以應該用 present perfect：I have been in love before（可能o既潛台詞：so I have the experience）
至於 I was in love 強調o既係一件往事，同現時無關。Simple Past 好多時會加埋個時間，如 I was in love with her at that time，強調當時。
ｑ２．
佢當左差五年，同樣應該用 present perfect，雖知呢個 tense 只係講到事情已開始左，但可以講結束影響至今／至今未完o既事（present perfect continuous 就強調說話當時o個一刻）：
He has been a policement for five years.
注意呢句唔係 passive voice，因為 passive 除左有 been 仲要有 past participle 先完整。反為 has being 就唔係任何 tense o既結構。

Answer to question 1:
It has always been tough.

I have been in love before.

Answer to question 2:
He has been a policeman now for five years.

This is how the English would say it believe it or not.
Hope this would help.

問題1
It is used to be very difficult.
I have been in love=我已墮入愛河
I have been in love before.
請記住,以前一直.....是 it used to......; 而現在一直都......是 it is used to...
問題2
He has being a policeman for five years.
我的英文都不是太好,但希望幫到你,我覺得has being 中間加been變了被動式,一個人做警察是他自己主動的,不是被動的,如果被派去某部門才要加been
