用法說明

to + V 與 to + V-ing 的區別
- to + 動詞原形 (to V) 是最常見的結構，表示動作的目的、意圖或未來方向。
- to + 動名詞 (to V-ing) 中的 "to" 是介系詞，後面必須接名詞或動名詞。常見於特定動詞或片語後，如 "look forward to", "be used to"。
- 區分關鍵在於判斷 "to" 是「不定詞標記」還是「介系詞」。介系詞 "to" 後方需接名詞性成分。
- 例如，"I want to go" 中的 "to" 是不定詞標記；"I am looking forward to seeing you" 中的 "to" 是介系詞。
