嗨~大家好，歡迎來到英文庫，我是 Jessie 👋 今天要跟大家分享 as…as… 的用法。
說到 as…as… 句型，你會想到什麼呢？或許一時片刻無法說出很多答案，但它不只是很重要的比較句型，在日常生活中也時常可以看到，像是要表達哪個東西比較貴，或是 email 常會看到的 as soon as possible（盡快）。英文中也有很多慣用法就是利用 as…as… 句型來譬喻，就像中文會說累得像狗一樣，所以學會這個句型也可以讓你的形容更生動和道地喔！這麼常見又實用的句型當然要好好認識，話不多說趕快往下滑~Here we go!
作為「與⋯⋯一樣程度」的用法
📌 as + 形容詞/副詞 + as
其中一個最常見的 as…as… 句型是兩個 as 之間夾著形容詞或是副詞，表示「A 和 B 一樣⋯⋯」。如果動詞是連綴動詞 （is, am, are, become, look, …），兩個 as 中間可以夾形容詞，補充說明主詞的狀態；一般動詞則是搭配副詞，用副詞來修飾動詞。
My feet are as cold as ice.
我的腳跟冰塊一樣冷。Columbus sings as well as Bruno Mars.
哥倫布跟火星人布魯諾唱得一樣好。Olivia felt unwell and looked as white as a sheet.
Olivia 覺得不舒服，臉色蒼白如紙。Wendy is as busy as a bee, preparing for moving.
Wendy 忙得團團轉，為搬家做準備。
📝 小補充：這個句型結尾的 be 動詞或助動詞通常會省略，因為即使省略掉句意還是很清楚。
Steve is as tall as his father (is).
Steve 跟他爸爸一樣高。Dora walked as slowly as her grandpa (did) after she injured her legs.
Dora 傷到她的腳後，走得跟她爺爺一樣慢。
如果想表達否定，「A 不像 B 一樣⋯⋯」，只要在 be 動詞或助動詞後面加上 not 就可以囉！

數學考試不像英文考試那麼簡單。William is not as busy as his supervisor.
William 沒有像他主管那麼忙。I can not dance as beautifully as the ballet dancer.
我沒辦法像那位芭蕾舞者跳得那麼優雅。Rita does not speak English as fluently as her brother.
Rita 不像她弟弟英文講得那麼流利。
📌 as + many/much 名詞 + as
如果想特別強調數量是一樣的，就可以用這個句型來表示「A 和 B 的⋯⋯（數量）一樣多」。句中的名詞如果是可以容易辨別出數量且有複數型的可數名詞，前面就要搭配 many；比較抽象、不易辨別出數量的不可數名詞則要搭配 much。（對可數、不可數名詞不熟的朋友，可以看看這篇 👉「可數名詞、不可數名詞」是什麼？有什麼規則？）

Owen 和 Ella 有一樣多把吉他。Claire wants to write as many novels as Stephen King.

Tim 跟他朋友吃一樣多的壽司。
作為「盡可能⋯⋯」的用法
📌 as + 形容詞/副詞 + as possible
另一個常見的用法就是將第一個句型 「as + 形容詞/副詞 + as」的句尾加上 possible，用來表達「盡可能⋯⋯」。

那位大廚總是盡可能將廚房工作檯保持乾淨。To win the contest, Ally swam as fast as possible.
為了贏得比賽，Ally 盡可能游得很快。The dog barked as loudly as possible to warn its owner that a stranger broke into the house.
那隻狗盡可能叫得很大聲，以提醒它的主人有陌生人闖入家裡。Just tell him to call me as soon as possible (=ASAP).
就叫他盡快打給我。
📌 as + 形容詞/副詞 + as + 人 can/could
除了 as…as possible，你也可以將 possible 改成「人加上 can 或 could」，一樣可以表示「盡可能⋯⋯」。
Keith kept as quiet as he could when studying in the library.
Keith 在圖書館念書時，盡可能保持安靜。The tennis player tried to stay as calm as he could before the tennis match started.

先生，我正盡可能划得最快了。
作為「倍數」的用法
說到倍數的用法很多人都一個頭兩個大，因為英文的寫法跟中文邏輯不太一樣 😵 但其實倍數的用法只是將前面介紹過的句型做一點變化而已，相信只要前面的內容你有吸收進去，倍數的用法你一定馬上就能學會了。
📌 倍數詞 + as + 形容詞/副詞 + as
一開始介紹過表示「A 和 B 一樣⋯⋯」的基本寫法是「as + 形容詞/副詞 + as」。如果要表示倍數時，只要在這個句型前面加上倍數詞 （twice、three times…）就可以了，是不是很簡單啊？
Tom Cruise’s house is ten times as big as mine.
湯姆．克魯斯的家是我家的十倍大。Pam’s jacket is four times as expensive as Danny’s.
Pam 的夾克價格是 Danny 夾克的四倍。The car cost three times as much as I had expected.
那臺車比我預期的貴三倍。The kangaroo can jump twice as high as the rabbit.
那隻袋鼠跳的高度是那隻兔子的兩倍。
📝 小補充：倍數詞除了 0.5 倍、兩倍比較特別，0.5 倍是 half，兩倍是 twice 或 two times，二之後的倍數詞都只要將數字加上 times（次數）就可以了，像是 five times（五倍）、 six times（六倍）。雖然 three times（三倍）也可以寫成 thrice，但現在幾乎沒有人在用，所以也不用特別去記它喔！
📌 倍數詞 + as + many/much 名詞 + as
大家還記得另一個表示「A 和 B 一樣⋯⋯」的寫法嗎？那就是 as + many/much 名詞 + as。要表示倍數時，一樣只要在這個句型前面加上倍數詞就大功告成啦！

Ashley 擁有的包包數量是她男友的兩倍。Vickey took three times as many photos as her classmate.
Vickey 拍的照片數量是她同學的三倍。There are five times as many sheep as humans in New Zealand.
