What is passive voice??

主語比其他人或物作出一些動作
例如中文既,我被拘捕,蘋果被狗吃了,他兩日後將會被任命為經理
係英文既12種tense只有9種係會有passive voise,而個動詞係會轉做p.p orm,我以eat做例子
present simple:is/am/are+eaten
present continue:is/am/are+being+eaten
present perfect:has/have+been+eaten
past simple:was/were+eaten
past continue:was/were+being+eaten
past perfect:had+been+eaten
future simple:will/shall+be+eaten
future perfect:will/shall+have+been+eaten
以剛才既兩句做例子,英文就係咁寫
I am arrested(by police).
The apple is eaten by a dog.
He wll be appointed to be a manager two days later.
