Hello, everyone! 我是英文庫的 Celine 🙂，今天一起來看看 as for 的用法吧！
不管是在口說還是閱讀，你可能多少都可以發現 as for 的蹤影，那 as for 到底是什麼意思？又該怎麼在句子中使用呢？而它跟 as to 是不是可以直接互相代換呢？今天這篇文章就會來一一解答你的疑惑唷！
不過在正式開始前，想讓你先暖身一下，看看你能不能從這兩個句子推測出 as for 的意思呢～
Anna is already here. As for Wayne, he will arrive later.
Jeremy is kind and generous. As for his wife, nobody likes her.
💡 答案：as for 是「至於」的意思，你答對了嗎？
如果沒有答對也沒關係，今天就是你認識 as for 的大好機會，等等也會告訴你那兩句話的翻譯，那話不多說，繼續看下去吧！
as for 的用法
as for 的中文意思為「至於」，特別指的是在講完某件事後，要提到跟前面相關的另一件事，所以原則上 as for 會搭配上下文，不太會單獨自己出現唷。
as for 通常會放在句首的位置，後面加上人或事物都行，用法上會搭配名詞或是動名詞。
Anna is already here. As for Wayne, he will arrive later.
Anna 已經在這裡了，至於 Wayne 呢，他會晚一點到。Jeremy is kind and generous. As for his wife, nobody likes her.
Jeremy 是個親切又慷慨的人，至於他老婆嘛，大家都不喜歡她。Many people went outside during the holidays. As for me, I just want to stay home and veg out.
很多人在放假時出去玩，而至於我呢，我只想待在家裡耍廢。We have prepared enough food for the party. As for drinks, could you buy some beers?
那場派對我們已經準備足夠的食物了，至於飲料嘛，你能去買一些啤酒嗎？
此外，as for 有時候也會依照語氣使用 and 或 but 和上一句連接唷，例如：
I can stay here for one more day, but as for staying for three days, that will be impossible.
我可以在這裡多待一天，但至於要再多留三天的話，那是不可能的。
as for 和 as to 用法一樣嗎？
可能有很多人在學校學過 as for 和 as to 可以互相代換，但這個說法只對了一半，as to 的確也有「至於」的意思，且一樣會放在句首的位置，不過用起來會比 as for 來得正式一點，也可以說聽起來會比較嚴肅，不過 as to 後面會加上事物為主，不太會用於人。
小結來說，as to 的用法現在比較少見，如果要表示至於…，會建議你使用 as for 為主唷，特別是在口說方面。
看看例句吧（以下句子也可以用 as for，這裡以 as to 來做示範）：
We really appreciate your assistance. As to the suggestion you offered, we will take it into consideration.
我們真的很感謝你的協助，至於你所提出的建議，我們會列入考量。You will receive the machine next Tuesday. As to how to use it, Linda will teach you.
你們將會在下週二收到那台機器，至於要如何使用，Linda 會教你們。
as to 可以放在句中
另外一個和 as for 不同的地方是 as to 可以放在句中，後面一樣會加上事物（名詞），而且此時常會和表示疑問、疑惑的字詞連用，像是 uncertain、confused 等等，例如：
There is disagreement as to the causes of the pandemic.
關於這場疾病大流行的起因為何是意見分歧的。We have no doubts as to his ability to do the project alone.
我們對於他有能力獨自執行那份專案是無庸置疑的。I was uncertain as to which decision to make.
我不確定要做哪個決定。They haven’t decided as to whether to cooperate with him.
他們還沒決定是否要和那個人合作。I’m very confused as to what you’re even talking about.
我甚至對於你在說什麼完全沒什麼頭緒。
That’s All for Today
相信看完這篇文章的你已經對於 as for 和 as to 分別有更進一步地了解了，不會只是停留在 as for = as to 的階段，記得 as for 可以用在人或事物，而 as to 會以事物為主，可以的話，建議使用比較常見的 as for 唷。學完這些觀念，下次不妨在口說與寫作上練習用看看吧！
