duplicate doing vs duplicate to do
- duplicate doing 通常用於描述重複一個已知的、具體的過程或動作。它強調的是複製「做某事」這個行為本身。
- duplicate to do 則常出現在表示目的或意圖的結構中，例如「in order to duplicate to + V」，意思是「為了複製以便去做某事」。
- 在一般陳述或指令中，duplicate 後面更常直接接名詞（duplicate the file）或使用被動語態（be duplicated），而較少直接接動詞-ing或不定詞。 EN: The software is designed to duplicate printing the document for archival purposes. 翻譯: 該軟體的設計是為了重複列印文件以作存檔之用。
EN:We need to duplicate the data in order to duplicate to run the simulation twice.
翻譯:我們需要複製數據，以便能重複運行模擬兩次。
總結建議
在大多數情況下，duplicate 作為動詞時，其後應直接接受詞名詞；若需表達目的，可使用 in order to duplicate 或 to duplicate 後接另一個動詞不定詞來表示。
