一.介詞與動詞的搭配
    同一介詞可以與不同的動詞搭配，表示不同的意思。以of為例：
    Jack reminds her grandma of her husband because he looks just like him.(使……想起)
    Have you ever heard of such a thing?(聽說)
    She often spoke of her life in China.(談起)
    The lady was robbed of 10 dollars on her way home.(搶劫)
    Thanks for thinking of me.(思念)
    同一動詞可以與不同的介詞搭配使用，表示不同的意思。以look為例：
    Look after the children.(照顧)
    He looked at the timetable.(看)
    What are you looking for?(尋找)
    The police are looking into the case.(調(diào)查)
    在許多動詞 + 介詞的結(jié)構(gòu)中，介詞實際上是動詞的一部分，與動詞一起構(gòu)成短語動詞。
