介詞是一些非常常見的小詞，例如at、for、in、on和to，通常位于名詞或代詞前面，表達與另外一個詞之間的關系。

母語是英語的人在常見的介詞使用中很少犯錯，然而，英語學習者經常犯錯，因為他們更多地是直接從自己的語言中翻譯，而非聽地道的英語。

提高介詞使用能力最好的方法是：

1. listen to spoken English as much as possible

盡可能多地聽英語口語

2. test yourself on common prepositions

自我測試常用的介詞

下面羅列了10個常見的介詞用法錯誤：

1) arrive at 還是 arrive in
