代词是词汇中不可或缺的一部分。其中表示人的英语代词有三类：人称代词、物主代词、反身代词。三者互相关联，是应用普遍也是重要的代词类别，也是期末考试中经常考查的重点。所以，今天就来跟大家讲讲这三类代词。
一、人称代词
表示自身或者人称的代词，分为主格和宾格。比如：“我”“你”“他”“她”“它”“我们”“你们”“他们”。
人称代词主格：作主语，表示谁怎么样了、干什么了。
例如：Ilikemusic(主语).我喜欢音乐。
人称代词宾格作宾语，表示动作行为的对象。
例如：Areyousureitwasthey(表语)？你确定是他们吗？
二、物主代词
表示所有关系的代词。 物主代词分形容词性物主代词和名词性物主代词。
形容词性物主代词（my，your等）在句中只用作定语，相当于一个形容词，不能单独使用。
例如：Myfootball.(形容词性物主代词修饰名词) 我的足球。
名词性物主代词（mine，yours等）相当于一个名词词组，可以单独使用，在句中用作主语、宾语、表语、和介词of连用。
例如：May I use your pen?Yoursworks better. (名词性物主代词作主语)我可以用用你的钢笔吗?你的钢笔比我的更好用。
三、反身代词
表示自身，比如“我自己myself”“你自己yourself”。
反身代词可用作宾语、同位语、表语等。
例如：Hehimselfwasadoctor.(同位语)他自己就是个医生。
Heistooyoungto take care ofhimself.（宾语）他太年轻了还不能照顾自己。
用作同位语时，主要用于加强被修饰词的语气，可紧放在被修饰名词后或句末。
Thatpoorboywasmyself.（表语）那个贫穷的男孩就是我自己。
