has been increasing 文法對嗎?

你想講,現在已經增加了/上升

首先 - 你無講明Subject係單數定係眾數
第二 - 你無講明嘜嘢上升,因為要分出主動(active)及被動(passive)

我估你多數都係講Active

若你想講,(現在)增加了/上升,用present continous tense
is/am.are increasing

若你想講,現在(已經)增加了/上升
(1) 若你不知之後會否上升或無講明之後會否上升,最好用present perfect tense
have / has increased
(2) 若你講明之後會上升(加強語氣),則用present perfect continous tense
have / has been increasing

若你講passive(現在)增加了/上升,用present continous tense用is/am/are being increased現在(已經)增加了/上升,用present perfect tensehave/has been increased

has been + ing : 指短時間內已經上升了，而且再有上升趨勢
has been + p.p.: 指短時間內已經上升了
