Which is why , this is why具有相同的含義,但有不同的細微差別。 Which is why聽起來聽起來沒那麼激動的原因,但這this is why聽起來直接而富有侵略性的原因。這兩個表達式均表示which/this is the reason why 。例子: I'm on a diet right now, which is why I didn't eat dessert. (我沒有節食which因為我節食。-聽起來很溫和)例子: This is why we don't get along, because you always start arguments.吵架This is why we don't get along, because you always start arguments. (您總是會爭論。這就是為什麼我們不能相處。- this is why聽起來很激進的this is why )
