一、代词 人称代词和物主代词 英语的人称代词（Personal Pronoun）有三种不同的人称形式：第一人称（First Person）；第二人称（Second Person）；第三人称（Third Person）。三种人称又各有单、复数形式。.在上列人称代词的不同形式中，还包含了主格（Subjective Case）、宾格（Objective Case）两种“格”的形式。这样，从“格”的形式来划分，英语的人称代词又可归纳为： 主格：I，you，he，she，it，we，you，they 宾格：me，you，him，her，it，us，you，them 此外，还有所有格形式。属格：my，mine，your，yours，his，her，hers，its，our，ours，their，theirs 属格又可分为两类：一类是形容词性物主代词（my，your，his，her，its，our，their）即 “物主限定词”；另一类是名词性物主代词（mine，yours，his，hers，ours，theirs），即 “物主代词”。 人 称 代 词 第一人称 第二人称 第三人称 单数 复数 单数 复数 单数 复数 主格 I we you you she\ he\ it they 宾格 me us you you her\ him\ it them 物 主 代 词 形物代 my our your your her \his\ its their 名物代 ours yours yours hers/his/its theirs 人称代词用法： Give it to me. Let’s go.(let’s=let is) 形容词性物主代词（my/your/his/her/its/our/their）+名词。 而名词性物主代词（mine/yours/his/hers/its/ours/theirs）则相当于形容词性物主代词+名词，故其后不必加名词。如： -Is this your book? -No,it isn’t,it’s hers(her book).[it’s Jim’s,it’s Tom’s.......] 名词性物主代词=形容词性物主代词+名词 　　为避免重复使用名词，有时可用“名词性物主代词”来代替“形容词性物主代词+名词”的形式。例：My bag is yellow, her bag is red, his bag is blue and your bag is pink. 为避免重复使用bag，可写成My bag is yellow, hers is red, his is blue and yours is pink. 1.________(我) am a teacher. 2.My father is talking with _______(我). 3.This is _______(我的) book. 4._______(他的) chair is blue. 5._______(我们的) classroom is big. 6._______(他) often plays basketball after school. 7._______(他的) teacher is good. 8._______(我们) buy a pair of shoes for _______(他). 9.Please pass_____(我们) the ball. 10._______(他们) are listening to the radio. 11.________(我) am a teacher. 12.This is _______(她的) bag.
