5、是一个说话算话的人。(先行词指人，关系代词who/that引导定语从句，并在从句中作主语)Is there anyone in your class whose father is a teacher?你们班有谁的父亲是老师？(先行词指人，关系代词whose引导定语从句，并在定语从句中作定语)To be frank,I dont like the movie(which/that)you recommended to me yesterday.坦率地讲，我不喜欢你昨天推荐给我的那部影片。(先行词指物，关系代词which/that引导定语从句，并在从句中作宾语，可省略)【名师点津】关系词，引定从

6、，它们的用法各不同。that可作主宾表，指人指物它都行。which专来指物用，主语、宾语它也能。who和whom来指人，whom仅作宾语用。whose一词作定语，指人指物都管用。(二)关系代词用that而不用which的情况1当先行词是all,much,anything,nothing,little,none等不定代词时(something,everything,anything作先行词时，关系代词偶尔也可以用which)She told me everything that she knew.她把她所知道的一切都告诉了我。2先行词既有人又有物时I can remember well the

9、a football.那是一个足球。2关系代词前有介词时This is the room in which he lives.这是他住的房间。3引导非限制性定语从句时Tom came back,which made us happy.汤姆回来了，这使我们很高兴。(四)定语从句的注意事项1关系代词在从句中作主语时，根据先行词的单复数确定从句谓语动词的单复数。如：He is the only one of the students who knows French in our class.他是我们班里唯一懂法语的学生。(the only one为先行词)He is one of the stud

10、ents who know French in our class.他是我们班里懂法语的学生之一。(students为先行词)2关系代词的省略：在限制性定语从句中，关系代词作动词的宾语或介词的宾语(这时介词不能在关系代词前)时常可省略。如：The boy(that/who/whom)we saw last night is Li Ming.我们昨晚见到的那个男孩是李明。3the same.as与the same.that的区别一般情况下，the same.as指的是与先行词同类的事物/人，而thesame.that与先行词指的是同一个事物/人。如：This is the same pen as
