第三课时 (Grammar Focus­4c) —单元同步语法精讲精练 英语 九年级下册 人教版 原创新课堂 ►定语从句的含义 在复合句中，修饰某一名词或代词的从句叫做定语从句。被修饰的名词或代词叫做先行词。从句放在所修饰的词(即先行词)之后，由关系代词或关系副词引导。 ►定语从句的引导词 定语从句的引导词可分为关系代词that，which，who(宾格为whom，所有格为whose)和关系副词where，when，why等。本单元我们主要学习关系代词引导的定语从句。 ►关系代词在定语从句中的用法 ①that既可指人也可指物，在句中作主语或宾语。 eg：He is a man that/who often helps others.(作主语) ②which指物，在句中作主语或宾语。 eg：She likes to live in a room which/that is big and bright.(作主语) I like the skirt which/that my mother bought me yesterday.(作宾语) ③who指人，在句中作主语或宾语。 eg：Here is the man who/that is the most handsome star in the film.(作主语) ④whom指人，在句中只能作宾语。 eg：He isn't the man whom/who/that I talked to just now.(作宾语) ⑤whose既可指人也可指物，在句中作定语。 eg：Is there anyone in our class whose father is a doctor？(作定语) 【注意】 ①关系代词在句中作主语时，谓语动词的单复数应与先行词的单复数一致。 eg：Tom is one of the boys that are from the USA. Tom is the only boy that is from the USA. ②关系代词在从句中作宾语时，关系代词可省略。关系代词前有介词时，不能省略。 eg：I love music (that/which) I can sing along with. The boy with whom I just talked about the school trip is my brother. ►定语从句中先行词为事或物时，关系代词只能用that而不能用which的情况 ①先行词被序数词或形容词最高级修饰时。 eg：This is the most beautiful mountain that I have seen.这是我所见过的最美丽的山。 ②先行词前有all，any，no，little，much，many，the only，the very，the last等修饰词时。 eg：This is the only book that I like.这是我唯一喜欢的一本书。 ③先行词本身是all，any，many，much，little，few，everything，something，anything等不定代词时。 eg：Is there anything that you want to know？你有想了解的事吗？ ④先行词里同时含有表示人和物的名词时。 eg：I can remember the people and some pictures that I saw in the room.我能记得我在这个房间里看到的人和一些图画。 ⑤主句是以who或which引导的特殊疑问句。 eg：Who is the boy that is playing football？正在踢足球的那个男孩是谁？ ►定语从句中先行词为事或物时，关系代词只能用which不能用that的情况 ①在介词后只能用which。 eg：This is the bank in which the robbery happened.这是那个发生抢劫案的银行。 ②先行词为that，those时。 eg：What's that which is in the sky？天空中的那个东西是什么？ ③引导非限定性定语从句。 eg：Mike passed the exam，which made us happy.迈克通过了考试，这使我们很开心。 一、根据句意，从括号中选择合适的关系代词填空。 1．I really like the photo of my family _______ (who/that) my sister took in the city park last year. 2．This is the dress _______ (wh
