咩叫passive voice?(盡量中文解釋- -)

何時要用passive voice 呢?

有時侯, 當不需要知道主詞的真正身份 或 沒有清楚列明是誰人做的,
我們就會用passive voice , 因為讀者巳對主詞不感興趣, 甚至可以不理.

以下句子為例:

讀者對髹漆師傅是誰並不感興趣, 只想知那間屋髹好油未, 在口語中,其實不用說 the workers 亦可以, 因為說了都不知是誰髹的, 所以用passive voice 較好

Active : The workers have painted the house.
Passive: The house has been painted (by the workers).

再舉另一例: (係人都知賊是被警察捉的, 所以人們只對賊人是否被捕有興趣, 因為無人想知警員名稱, 因此, the police 可以刪去, 用passive voice較好)

Active : The police arrested the thieves.
Passive: The thieves were arrested (by the police).

passive voice 係一種英文文法~~~~~有時候我地同動詞~~~

e.g. Mary drinks the water~~~~

姐係瑪莉飲水la~~~

咁passive voice~~~就會係

e.g. The water is drunk by Mary~~~~

姐係d水比瑪莉飲左la~~~

passive voice就係將主動式變被動式~~~~

唔知幫唔幫到你~~~ 希望得~~~

P.S 佢會加is/am/are.was/were/是乎個tense係咩野~~~~
