代词代词有两种：人称代词和物主代词。1、人称代词分为：第一、第二、第三人称，且有单复数之分。2、人称代词的主格在句中做主语，一般用在动词前（疑问句除外）；宾格在句中做宾语，多用于动词、介词后。3、形容词性物主代词起形容词的作用，后面一定要跟名词，表示该名词是属于谁的。4、名词性物主代词=形容词性物主代词+名词。如：Thisismybag.=Thisismine.Thatisherruler.=Thatishers.一般看后面有没有名词，如有，就用形容词性物主代词；如无，就用名词性物主代词。请牢记下表：单数复数人称代词主格Iyouhesheitweyouthey宾格meyouhimheritusyouthem物主代词形容词性myyourhisheritsouryourtheir名词性mineyourshishersitsoursyourstheirs练一练：1、按要求写出相应人称代词。I（宾格）_______she（形容词性物主代词）_______we（名词性物主代词）_______he（复数）_______us（单数）_______theirs（主格）_______its（宾格）_______2、想一想，把下表补充完整。人称代词物主代词单数复数单数复数主格宾格主格宾格形容词性名词性形容词性名词性第一人称meusour第二人称youyouyouryoursyouryours第三人称hetheythemhishistheirshehersitits3、用所给词的适当形式填空。1）Thatisnot_________kite.Thatkiteisverysmall,but_________isverybig.(I)2）Thedressis_________.Giveitto_________.(she)3）Isthis_________watch?(you)No,it’snot_________.(I)4）_________ismybrother.________nameisJack.Look!Thosestampsare_________.(he)5）_________dressesarered.(we)Whatcolourare_________?(you)6）Show_________yourkite,OK?(they)7）Ihaveabeautifulcat._________nameisMimi.Thesecakesare_________.(it)8）Arethese________tickets?No,________arenot_________.________aren’there.(they)9）Shall_________havealookatthatclassroom?Thatis_________classroom.(we)10）_________ismyaunt.Doyouknow_________job?_________isanurse.(she)
