内 容 提 要

　　代词分人称代词、物主代词、反身代词、不定代词、指示代词、关系代词和连接代词，它们在句子中承担不同的功用。

　　人 称 代 词

　　一、主格人称代词有I， we， you， he， she， they， it，主格人称代词就是在句中充当主语和表语的代词

　　二、宾格人称代词有me， us， you， him， her， them， it，宾格人称代词即在句中充当宾语(含介词宾语)的代词

　　三、同步练习

　　2) Legends often contain an element [A] of fact， but [B] sometimes it is [C] totally [D] untrue.

　　5) Most of we [A] know that conductors direct their orchestras with a baton， but how many [B] are aware that [C] they also direct with their faces， hands [D] ， and shoulders

　　四、例题解析

　　1) C错。him是宾格，而此处却需要作主语的人称代词，故应将him改为主格he.

　　2) C错。 改为they are.C处代替的是“Legends”而不是“an element”。

　　3) D错。them也是宾格，应改用主格they，作定语从句中的主语，谓语为travel.

　　4) A错。 改为me.

　　5) A错。改为宾格us，因为前面是介词of，us作其宾语，故用宾格。

　　物 主 代 词

　　一、表示人的物主代词用my， our， your， his， her和their，指无生命的东西用its(但指国家时一般用she或her)，它们在句中作定语

　　二、名词型物主代词能作表语(It's theirs)、主语(Mine is there)、宾语(I don't like hers)，与of连用可以作定语(the food of theirs)。
