1、1 2019 年最新七年级上册英语语法知识点大全 一、代词 1、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
2、，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”。 2 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
3、you you her him it them 物 主 代 词 形物代my our your your her his its their 名物代mine ours yours yours hers/his/its theirs 人称代词用法： （1）人称代词主格：做主语，表示谁怎么样了，干什么了。 I am a teacher. You are student. He is a student , too. We/You/They are student. （2）人称代词宾格：作宾语，表示动作行为的对象，一般放在动词的后面。 Give it to me. Let s go.(lets=let
4、 is) （3）形容词性物主代词（my/your/his/her/its/our/their）+名词。 （4）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 isnt,its hers(her book).its Jim s,its Toms. 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,
5、 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. 练习： 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. 3 6._( 他) often plays basketball after school.
