什么是代词？
代词是代替名词或名词短语的一种词类。大多数代词具有名词和形容词的功能。英语中的代词，可分为：人称代词、物主代词、指示代词、不定代词、疑问代词、关系代词、反身代词、连接代词和相互代词九种。
小学阶段主要接触的是前5种。
1）人称代词 是表示“我”“你”“他”“她”“它”“我们”“你们”“他们”的词，是表示自身或人称的代词。人称代词有单复数以及格的变化。
1.第一人称 第一人称主格-宾格 单数I-me复数we-us
人称代词的主格作主语。I am a girl,我是一个女孩。We go to the park every Saturday.我们每周六去公园。
人称代词的宾格作宾语。Give me a pencil, please.请给我一支铅笔。Miss Fang teaches us English.方老师教我们英语。
2.第二人称和第三人称
第二人称主格-宾格 单数you你-you你 复数 you你们-you你们
第三人称主格-宾格 单数he他- him他 单数she-她her她 单数it它-it它
复数they 他们-them 他们、她们、它们
第二、第三人称在用法上与第一人称一样。
