比較句型

as/so ... as ...
結構︰as/so+形容詞或副詞原級+as…
說明︰此句型意為“…和…一樣…”。比較兩件東西，並表示它們的程度一樣。第一個 as 為<副詞>，第二個 as 則為<副詞><連接詞>，引導<副詞子句>，修飾第一個 as。在 as…as 中可插入單數<可數名詞>，即：“as+<形容詞>+a/an+<名詞>+as”。若是複數<名詞>，可用“as many/few+複數 <名詞>+as”;若是<不可數名詞>，則用“as much/little+<不可數名詞>+as”。“as+原級(形、副)+as+原級(形、副)”這形式表示有關同一人(物)的兩種不同的性質、狀態是一樣程度的，譯作“既有…且還有…”。
