ex:Many customers have complained about the product. That's why it has to be redesigned. (許多客戶對這項產品有諸多抱怨。這是為什麼它必須重新設計。)
ex:Costs have gone up. As a result, we must increase the price five percent. (成本業已上昇。結果使得我們必須調漲價格百分之五。)
ex:Actually, that is not the main reason.(其實,那並不是主要的原因。)
ex:In fact, it's not really possible.(事實上,這並不怎麼可能。)
情境小撇步
that's why 和 that's because
that's why 和 that's because 兩個句子都可以用來解釋說明,乍看之下會覺得 兩句是一樣的,其實並不相同,that's why後面接結果,that's because後面接原因,例如:He is sick, that's why he stays at home. (他不舒服,這也是為什麼他留在家的原因。) 、He stays at home, that's because he is sick. (他留在家,這是因為他不舒服。),前一句重點在於解釋原因,後一句重點在於 說明結果。
