急問一d有關現在完成式的問題

Surely, no problem

Because :

Present perfect tense denotes on things that happened in the past but is affecting the events happening now

So your sentence is in the above situation. Therefore, you are correct.

Moreover, we should also look at the following aspects while considering if the sentence is correct:

grammar - correct
tense - correct
logic - no problem
content of sentence - correct

Hence, your sentence is correct.

HOPE I CAN HELP YOU ^_^

12 對 1
12 人認同用現在完成式, 到目前只有我覺得有問題
佔領中環結束了己經兩個月,發問者與朋友是知道
end 不是 durative verb, 沒有考慮 aspect 與 mood

例如 ,
Baby 現在兩個月大, 生這個嬰孩己經發生咗的事
bear 不是 durative verb
This baby has been born. ~ 用現在完成式有無問題?

我不會用現在完成式
我會講 "This baby was born in December last year."

我會有以下修改, 改為被動詞, 因為如果我寫, occuply Central 會加 "action", 整個作為名詞用. 所以會改 end 為被動詞.

Occuply Central" has been ended -

否則, 前面就要加 "we" , 再修改一下, 先可以用 has ended. 但作為報導式文句, 感覺好怪. 因為用左 we, 就有個人參與性, 而唔係中立.

Present perfect tense denotes present results of the past actions.
Note that the words "just" and "already" are used. "just' is used to mean the immediate past while "already' means complettion.
(1)Occupy Central has just ended.
(2)Occupy Central has already ended.

想信是沒有問題。因為你說 " Occupy Central has ended" , 這句說話是用
present perfect tense. 雖然現在是 2015 年，佔領中環是在 2014 年結束。
Present perfect tense 是現在完成式，己經發生咗的事，之後幾時講都可以。

(A) has ended, has just ended, has already ended ---
都是用於 Occupy Central 完結了不久，所以用「現在完成式」。
分別是：
(1) 若只想簡單說「Occupy Central已完結」，
可用： Occupy Central has ended.
(2) 若想強調 Occupy Central「剛」完結，
可用： Occupy Central has “just” ended.
(3) 若想特別強調Occupy Central「己經完結」，
則用： Occupy Central has “already” ended.

2015-02-24 15:01:27 補充：
(B) 若 Occupy Central 己完結了一段時間，則用「過去式」：
e.g. Occupy Central ended last December

(C) 但並不可以說 ：Occupy Central “ has been ended” 。因為 Occupy Central 並不可以「被完結」！
