passive voice唔明呀！！

passive voice的結構是
verb to be + past participle，即is/am/are/was/were +PP (即go/went/gone 的gone, drive/drove/driven 的driven等)

幾時用？

當該物件（object謂語）係被人take action時就用，如

I eat an apple.
咁apple 咪係object, 我係subject(主語), 意思係我食萍果，我係主角，係我對個萍果做動作（食）

如果你轉passive voice
要寫
The apple is eaten by me.
咁is eaten係passive voice的結構，而個動作就係「萍果被我食左」，因為本是object的萍果現在在這句被動句中變成左subject.

但如果你寫
The apple eats me.　就好明顯係錯，首先佢唔係passive voice的結構，而意思變左萍果食我喇。

咁如你寫
I am eaten by an apple.
結構係passive voice 的結構，但意思變左我被萍果食左，都唔岩


轉passive voice要注意兩個特點：
1.　要用passive voice結構，即verb to be （is/am/are/was/were ）+ past participle
2.本來在句尾中的object要放在句子最前面，變成subject
3. 若然知道個動作係邊個做的話, 就加埋 by 邊個.


唔知咁解你明唔明

Passive Voice e.g.:
use is/are/was/were/have/has/had/+ past participle
