Preposition的意思

"Preposition" 是一個英語語法術語，它指的是用來表示名詞、代詞或名詞短語與句子其他部分之間的關係或位置的詞。簡而言之，介詞用來表示詞與詞、短語與短語或者句子與句子之間的邏輯關係。

介詞通常放在名詞、代詞或名詞短語之前，形成介詞短語。介詞短語可以用來修飾動詞、形容詞或另一個介詞短語。介詞的常見用法包括：

1. 表示位置或方向，如 "in," "on," "under," "above," "behind," "between," "among" 等。
2. 表示時間，如 "at," "on," "by," "before," "after," "since," "until" 等。
3. 表示方式、手段或工具，如 "by," "with," "in," "on," "through" 等。
4. 表示原因、理由或邏輯關係，如 "for," "because of," "due to," "owing to" 等。
5. 表示比較，如 "than"。
6. 表示所有格或所屬關係，如 "of," "from" 等。

介詞的用法非常靈活，而且很多介詞的含義和用法可能很微妙，需要通過上下文來理解。學習介詞的一個好方法是通過例句來掌握它們的用法。
