用法說明
How is "Underlying" different from similar structures?What usage mistakes are common with "Underlying"?
underlying + noun vs underlying + that-clause
- underlying + noun 是最常見的結構，用於直接修飾一個名詞，描述其隱藏或根本的性質、原因或事實。
- underlying + that-clause 則用於引導一個子句，具體說明這個隱藏的事實或假設是什麼。這種結構較為正式，且通常用於抽象概念或論述中。
- 兩者不可互換。
underlying後面接名詞時，它是一個形容詞；後面接that子句時，它引導的是對「隱含內容」的具體說明。 EN: The report failed to address the underlying problem of poor communication. 翻譯: 這份報告未能解決溝通不良這個根本問題。
EN:The theory is based on the underlying assumption that all participants act rationally.
翻譯:這個理論建立在一個根本假設上，即所有參與者都會理性行事。
總結建議
在大多數情況下使用「underlying + 名詞」的結構；當需要明確闡述隱含的具體事實或假設時，才使用較正式的「underlying + that 子句」。
