2019年最新七年級上冊英語語法知識點大全

1、2019年最新七年級上冊英語語法知識點大全一、代詞1、 人稱代詞和物主代詞英語的人稱代詞（Personal Pronoun）有三種不同的人稱形式：第一人稱（First Person）；第二人稱（Second Person）；第三人稱（Third Person）。三種人稱又各有單、復數(shù)形式。.在上列人稱代詞的不同形式中，還包含了主格（Subjective Case）、賓格（Objective Case）兩種“格”的形式。這樣，從“格”的形式來劃分，英語的人稱代詞又可歸納為：主格：I，you，he，she，it，we，you，they賓格：me，you，him，her，it，us，you，them

2、此外，還有所有格形式。屬格：my，mine，your，yours，his，her，hers，its，our，ours，their，theirs 屬格又可分為兩類：一類是形容詞性物主代詞（my，your，his，her，its，our，their）即 “物主限定詞”；另一類是名詞性物主代詞（mine，yours，his，hers，ours，theirs），即 “物主代詞”。人稱代詞第一人稱第二人稱第三人稱單數(shù)復數(shù)單數(shù)復數(shù)單數(shù)復數(shù)主格Iweyouyoushe he itthey賓格meusyouyouher him itthem物主代詞形物代myouryouryourher his itsthei

3、r名物代mineoursyoursyourshers/his/itstheirs人稱代詞用法：（1） 人稱代詞主格：做主語，表示誰怎么樣了，干什么了。I am a teacher.You are student.He is a student , too.We/You/They are student.（2） 人稱代詞賓格：作賓語，表示動作行為的對象，一般放在動詞的后面。Give it to me.Lets go.(lets=let is)（3） 形容詞性物主代詞（my/your/his/her/its/our/their）+名詞。（4） 而名詞性物主代詞（mine/yours/his/her

4、s/its/ours/theirs）則相當于形容詞性物主代詞+名詞，故其后不必加名詞。如：-Is this your book?-No,it isnt,its hers(her book).its Jims,its Toms.名詞性物主代詞=形容詞性物主代詞+名詞為避免重復使用名詞，有時可用“名詞性物主代詞”來代替“形容詞性物主代詞+名詞”的形式。例：My bag is yellow, her bag is red, his bag is blue and your bag is pink. 為避免重復使用bag，可寫成My bag is yellow, hers is red, his is
