2009年高考英语第二轮语法专题复习教案七：定语从句VIP专享

2009 年高考英语二轮语法专题复习七定语从句一、定语从句1．定语从句三步：第一找出先行词；第二看先行词在定语从句中的语法功能（做主语、宾语或状语）；第三选择合适的关联词。2．定语从句在选择关连词 that 与 which 时，常常容易出错，所以应记住什么时候只能用 that，什么时候只能用 which. w.w.w.k.s.5.u.c.o.m（1）．只能用 that 的情况归纳 4 种：即先得词被序数词最高级修饰过；先行词为 all 、everything、nothing 等不定代词；先行词同时是人和物并列时；最后先行词分别被 the only 、the very the same、the last 修饰。请看下列四组例句，注意其先行词：①．The first thing that we should do is to work out a plan .②．I t almost seemed as if the good man were trying to teach us all that he knew at this lesson .③．Later my father and Mr.Crosset talked for about half an four of things and persons that they remembered in school.④．This is the very dictionary that I want to find .（2）．只用 which is 情况有两种情况：一是非限制性定语从句，关连词要用 which；二是做介词宾语时只能用which。请看下列两组例句：I said nothing , which made him more angry .I have the book about which you are talking .三、在定语从句的非限制性定语中，which 和 as 是容易混淆的。在很多情况下两者兼可互换，但在下列情况中不可互换：1、通常 As 可以放在整句的句首，而 which，只能在逗号之后，as 本身含有“正如”，as 在定语从句中既可是主语也可做宾语As appear from her paper ,she has read widely in Romantic literature.She is remarkable, as I have told you . w.w.w.k.s.5.u.c.o.m2、 which 在做非限制性定语从句关联词时可以无明确先行词，指前句整个的意思，如：she has warried again,which surprises us .四、在定语从句中，许多人往往分不清 all that 和 what,what 实际上只引导名词性从句，它相当于 all that 两个字，例如：All that I know is that he has made up his mind to heave the country for a new place. = what I know is that ……一、限定性定语从句：种类先行词关联词例句说明定语从句（...
