用法說明
How is "Primarily" different from similar structures?What usage mistakes are common with "Primarily"?
primarily doing vs primarily to do
- primarily + V-ing 通常用於描述主要的功能、目的或活動狀態，強調一個持續性或習慣性的核心作用。
- primarily + to + V 則更直接地指出主要「目的」或「意圖」，常用於解釋做某事背後的「原因」或「目標」。
- 在描述一個系統、工具或人的主要「用途」時，兩種結構常可互換，但細微差別在於 V-ing 偏向「功能描述」，而 to V 偏向「目的說明」。
- 當句子主語是「物」而非「人」時，使用 primarily for + V-ing / N. 來表示用途也非常常見。 EN: This software is primarily used for editing videos. 翻譯: 這款軟體主要用於編輯影片。
EN:This tool was created primarily to simplify the editing process.
翻譯:開發這個工具主要是為了簡化編輯流程。
