高考英语复习定语从句
语法复习四：定语从句（一）定语从句一般由关系代词和关系副词引导1、关系代词：who, whom, whose, which, that, as2、关系副词：when, where, why关系代词和关系副词必须位于从句之首，主句先行词之后，起着连接先行词和从句的作用，同时在从句中又充当句子成分。
e.g. She is the girl who sings best of all.（关系代词who在从句中作主语）The comrade with whom I came knows French.（whom在从句中作介词with的宾语）3、关系代词和关系副词的用法：1）当先行词为人时用who 作主语，whom作宾语；2）当先行词为物或整个句子时用which ，可作主语或宾语；3）先行词为人、物时用that ，可作主语或宾语；4）whose用作定语，可指人或物；5）关系副词when（指时间，在定语从句中作时间状语，where（指地点，在定语从句中作地点状语），why（指原因，在定语从句中作原因状语）。
（二）限制性定语从句与非限制性定语从句1、限制性定语从句：从句与主句关系密切，去掉从句，主句意义不完整，甚至不合逻辑。
e.g. I was the only person in our office who was invited.（去掉定语从句，意思就不完整）2、非限制性定语从句：从句对先行词关系不密切，去掉定从句，意思仍然完整。
形式上用逗号隔开，不能that用引导。
e.g. Tom’s father, who is over sixty, still works hard day and night.（who引导非限制性定语从句，整个句子可分成两句来翻译）（三）使用定语从句时特别注意的几个问题1、that与which的区别。
1）用that而不用which的情况：①先行词为不定代词all, anything, nothing, …；②先行词有最高级修饰，有序数词修饰；③先行词有only, very, any等词修饰；④先行词既有人又有物时。

定语从句一、定义及特点：在复合句中用来修饰某一名词或代词的从句叫定语从句。
其特点是定语从句的引导词是先行词的替身，既起联系作用，同时又充当定语从句的一个成分，所以掌握定语从句的关键在于：弄清楚其先行词的所指、所作成分和可否省略。
二、分类及区别：定语从句分为限制性定语从句和非限制性定语从句两种。
它们的区别有四点：1、从重要性上看：限制性定语从句在整个句子中比较重要，省去后会影响整个句子意思的表达；而非限制性定语从句则反之。
2、从句子形式上看：限制性定语从句的引导词前面无逗号，而非限制性定语从句的引导词前面有逗号。
3、从引导词上看：that，why可以引导限制性定语从句，但却不可以引导非限制性定语从句。
4、从引导词可否省略上看：在限制性定语从句中作宾语的引导词可以省略，而在非限制性定语从句中的引导词无论作什么成分都不可以省略。
三、用法（详解）一、限制性定语从句的用法：（一）关系代词引导的定语从句。
1、关系代词that，which，who，whom，whose，as引导的定语从句的用法。
⑴that可以指人，也可以指事物，在定语从句中作主语或宾语（作宾语时可以省略）。
如：Who is the man that is reading a newspaper there？（作主语指人）The girl（that）we saw yesterday is Jim's sister.（作宾语指事物）A dolphin is an animal that lives in the sea.（作主语指事物）The moon cakes that mother cooked taste nice.（作宾语指事物）⑵which指事物，在定语从句中作主语或宾语（作宾语时可以省略）。
如：The silk which is produced in Suzhou sells well.（作主语指事物）The song（which）the singer sang were very popular.（作宾语指事物）⑶who，whom指人：who，whom在定语从句中分别作主语或宾语（who也可以作宾语，who/whom作宾语时可以省略）；whose可以指人（= of whom）或事物（=of which）不可以省略）。
如：The student who sits on my left is an American.（作主语指人）The person（who/whom）you just talked to is our headmaster.（作宾语指人）I know the woman whose daughter studies abroad.（作定语指人）⑷as指物，常用于such…as，the same…as，as…as结构中，在定语从句中作宾语、表语、定语和状语，不可以省略。
如：This is not such a book as I expected.（作宾语指物）It is the same place as it used to be.（作表语指物）I like the same book as you do.（作定语指物）I shall do it in the same way as you did.（作状语指物）（二）关系副词引导的定语从句。
1、关系副词when，where，why引导的限制性定语从句的用法。
⑴when指时间，在定语从句中作时间状语，不可以省略。
如：We still remember the years when/during which we studied together.⑵where指地点，在定语从句中作地点状语，不可以省略。
如：This is the place where/in which he lives.⑶why指原因，在定语从句中作原因状语，不可以省略。
如：Do you know the reason why/for which I was late for class？定语从句考点讲解根据定语从句先行词的所指（指人/物/时间/地点/原因）、先行词的所做成分、及其可否省略，三个因素来综合确定定语从句的引导词。
一、四个引导词1.只用that引导定语从句的情况：①当先行词既有人又有物时，只能用that。
如：They talked about the things and persons that they remembered in the school.②当先行词是数词或all，much，little, everything，anything，nothing，none，the one等指物的不定代词时，只能用that。
如：Y esterday I caught two fish and put them in a basin of water.Now you can see the two that are still alive.I had to remember everything that the teacher taught me.注意：当先行词是something时，关系代词用that/which都可以；当先行词是someone，anyone，everyone，somebody，anybody，nobody，everybody，all，those，one（s）指人时，关系代词用that，who，whom都可以。
③当先行词被all，much，some，any，（a）few，(a) little，no, none, no one等修饰时，只能用that。
如：I have done all the things that he told us to do. He has no books that I need.④当先行词是序数词/形容词最高级或被序数词/形容词最高级修饰时，只能用that。
如：He was the first（person）that got to the top of the Mount Qomolangma.He worked out the most difficult problem that I had seen.I like the tallest（person）that was asked to come here.⑤当先行词被the very，the only，the last修饰时，只能用that。
如：It is the very book that I am looking for.⑥当主句主语为what, who，which开头的特殊疑问句时，只能用that。
如：Who is the boy that was here just now？Which is the bike that you lost？⑦主句是There/Here be结构时，当主语指物时，修饰其主语的定语从句用that引导；同时，定语从句部分是there be…句型时，也只能用that引导。
如：There is still a seat that is free.He asks for a book that there is on the subject.⑧当句子中有两个以上从句，其中一个已经用了which时，只能用that。
如：Edison built up a factory which produced things that had never been seen before.⑨当先行词是主句的表语而引导词又在定语从句中作表语时，只能用that。
如：China is no longer the country that it used to be.2.只用which引导定语从句的情况：①作介词的宾语且介词提前的时候（此时which不可省略）。
如：This is the house of which the windows face south.②引导非限制性定语从句的时候（此时which不可省略）。
如：His dog，which was very old，became ill.③一个句子有两个定语从句时，为了避免重复，一个用that引导，另一个用which引导。
如：He built up a factory that produce things which had never been seen before.④先行词为that/those时。
如：What was that which we saw last night?⑤先行词后面有插入语时。
如：The book, I thought, which you lent me yesterday is very expensive.3. as引导定语从句的情况：as可以引导限制性定语从句，也可以引导非限制性定语从句，as在从句中作主语、表语和宾语。
如：We have found such materials as are used in their factory. (as作主语)These houses are sold at such a low price as people expected. (as作宾语)He is not the same man as he was. (as作表语)①as引导限制性定语从句的情况：a.当先行词被such, so, as修饰的时候，常用as引导定语从句。
此时应注意与such/so…that 引导的结果状语从句区别开来。
如：He is such a good person as I always dream of making friends with. （as引导的定语从句）He is such a good person that I always dream of making friends with him. （such…that引导的结果状语从句）He is so clever a boy as everyone likes. (as引导的定语从句)He is so clever a boy that every one likes him. (as引导结果状语从句)b.注意the same…as与the same…that引导定语从句的区别：如：This is the same pen as I lent to you. (这和我借给你的那支笔相似。
)This is the same pen that I lent to you. (这就是我借给你的那支笔。
)c. 注意：….such as…结构中，such为代词，意为这样的人或物，as在从句中作成分，修饰先行词such的用法。
