7. as… as…結構在某些固定搭配中，要注意分清是用于本義還是用于習語義。如：

(1) as good as用于字面義，表示“與……一樣好”，可視為as…as結構與good的自然搭配；若用作習語，則表示“幾乎”“無異于”“實際上”。如：

A: Is he as good as her at chess? 他下棋也像她下得一樣好嗎?

B: There's no comparison. 根本不能比。

He as good as said I'm a liar. 他無異于說我撒謊。

The matter is as good as settled. 這事等于解決了。

另外，還有以下習慣搭配，其翻譯不能隨便從字面來理解：(as) good as a play 非常有趣；(as) good as gold 表現很好的；(as) good as new 完好如新；as good as one’s word 守信； as good as pie 很好的，可愛的，討人喜歡。

(2) as often as用于字面義，表示“與……一樣經常”，可視為as…as結構與often的自然搭配；若用作習語，則表示“每當”。如：

I don't visit my parents as often as I should. 我去看望的次數不夠經常。

As often as I tried to phone him the line was engaged. 每次我給他打電話都占線。

另外，習慣搭配as often as not的意思是“往往”“通常”，不能按字面來理解。如：As often as not, he forgets his homework. 他常常忘做家庭作業。

其他的還有：

as soon as 字面意思為“與……一樣快”；作為習語，其意為“一……就”。

as long as字面意思為“與……一樣長（久）”；作為習語，其意為“只要”。

as well as字面意思為“與……一樣好”； 作為習語，其意為“不但……而且”“既是……也是”“而且”“還”。等等。
