Grammar focus---4c Review 定语从句 1.Is there anything that I can do for you? 2.The girl who dances for people is a dancer. 3.This is the most beautiful city that I've ever seen. 4. You can borrow any book that you want to read in the library. 5.Which is the bus that you will take? 6.The man who acts in the movies is an actor. 7.This is the first time that I have been abroad for traveling. 那它们的定语呢？？？ I like music (that/which )I can dance to. I like singers who /that can write their own songs. 注意： 1.定语从句中先行词是物，从句用that/which引导。 2.定语从句中先行词是人，从句用who /that引导。 语法：定语从句 在复合句中修饰名词或代词的从句叫做定语从句。 先行词 先行词 关系词 关系词 定语从句 定语从句 定语从句修饰的名词、代词等称为先行词，引导定语从句的词称为关系词。 I have an apple. The apple is red. I have an apple that/which is red. 修饰先行词 an apple I like some friends. Some friends like sports. I like frineds who/that like sports. 修饰先行词 friends 关系代词三功能 常见的关系代词有that, which和who (宾格whom)。 that 既可以用于指人，也可以用于指物，在从句中作主语或宾语。作主语时不可省略，作宾语时可省略。 e.g. Mr Smith is the person that led us through that forest. Do you know the woman (that) Mrs Smith is talking to? This is the new computer (that) Tim bought yesterday. 连词作用，引导从句 代替先行词 在从句中充当一个成分，起句法作用 which 用于指物，在从句中作主语或宾语。作主语时不可省略，作宾语时可省略。 e.g. My home town is a city which has a history of 2,000 years. The city (which) we live in has a population of six million. who, whom用于指人，在从句中，who作主语，whom作宾语(常可省略)。在口语中，有时可用who代替whom, 也可省略。 e.g. He is the doctor who saved the girl's life. The man (who/whom) you're waiting for has come. 只能用关系代词that而不用which的情况:1) 当先行词是 all, any, few, little, none, anything, everything, nothing, everybody, nobody, everyone, no one 或被它们修饰时。2) 当先行词被形容词最高级或序数词修饰时。3) 当先行词有the very, the only, the same, the last等修饰时。4) 有两个或两个以上先行词，兼指人和物时。 只能用关系代词which而不用that的情况:1) 引导非限制性定语从句（主句和从句之间用逗号隔开）时。2) 先行词指物，且关系代词前面有介词时。3) 先行词为that或those时。 Exercise 1.
