形式與用法
as... as...
核心結構:as + 形容詞/副詞 + as + 比較對象,表示「程度相同」。可搭配程度副詞(just, almost, nearly, quite 等)加強語氣。數量表達:as many/much/few/little + 名詞 + as。否定:not as/so … as(英式正式可用 so,美式常用 as)。倍數:twice/three times/half as … as。第二個 as 後若重複動詞,可用助動詞替代(you do/you did),或直接省略。口語中 as 後常用受格(me/him),正式文體可用主格(I/he)並保留動詞(I am/he is)。也可用「as + 形容詞 + a/an + 單數名詞 + as」(e.g., as big a fan as)。

常見錯誤
He is as taller than me.
He is as tall as me. / He is as tall as I am.
as…as 使用形容詞原級(tall),不能接比較級(taller),且結構應為 as … as,不可接 than。
He is so tall as me.(肯定句)
He is as tall as me. / He is as tall as I am.
肯定句應用 as…as;not so … as 多見於否定且偏正式,肯定句不可用 so … as。
I have as much books as you.
I have as many books as you (do).
many/few 搭配可數複數名詞;much/little 搭配不可數名詞。books 為可數複數,需用 many。
Finish the report as possible as.
Finish the report as soon as possible.
固定搭配為 as … as possible,中間須是形容詞/副詞(如 soon/fast/quickly),不可將 possible 放到句末成 as possible as。
This bag is twice more expensive than that one.
This bag is twice as expensive as that one.
倍數比較用 twice/three times/half as … as,不用「twice + 比較級 + than」。
She runs as faster as her sister.
She runs as fast as her sister.
as…as 中副詞需用原級(fast),不能用比較級(faster)。
同義詞與反義詞
