主格：I you he she it we you they賓格：me you him her it us you them 形容詞性物主代詞： my your his her its our your their名詞性物主代詞： mine yours his hers its ours yours theirs 人稱代詞的主格一般作主語，是動作的發出者。賓格是動作的承受者，作賓語。動詞或介詞的後面用賓格。如： She often helps me. He sent some flowers to her. 形容詞性物主代詞相當於是形容詞，後面要跟名詞；句詞性的物主代詞相當於名詞，後面什麼都不跟。如： ---Whose is this book? 回答1： ---It"s my book. 回答2： ---It"s mine. 兩種回答意思一樣。
