介係詞用法
介係詞用法其實不難掌握。我們在第3.6章節提及過有關介係詞的基礎，但有時我們都不明白何時要用到介係詞。有些句子加入介係詞後可能會變了另外一個意思，但有時不加入介係詞有變了英文病句。完成以下英文練習題了解介係詞的正確用法。

“agree with”後面是人物或建議。“agree to”後面是進行某些事，例如：The company agreed to refund the customers。

“arrive”後加“at”代表到達指定地方（building、park等）。後面加”in“就代表到達一個地區、城市或國家。但如果到達”home“、”here“、”there“就不用加”at“或者”in“了，例如：When she arrived home, her husband had the meal ready.
They call him _______.
“call”後面不要加“as”。
