ENGLISH QUESTIONS~

1.I watched the part which Sadie pretended to be a victim.
我想問下呢句岩唔岩?咁以下呢2句有咩唔同?同埋邊句好啲?
2.I watched the part which Sadie pretending to be a victim.
2.I watched the part which Sadie pretends to be a victim
我仲想問下點解第2可以係 Sadie pretending ,而唔係sadie was pretending/is pretending?咁如果用番was pretending/is pretending又得唔得?

同埋我想問下我睇啲英文書既時候,佢地會轉present tense做past tense
咁佢地會轉past perfect,past,past continuous,persent perfect做咩tense?
問左好多,希望可以答到我啦thx^^~
