新概念英语第二册 定语从句+专项训练（含答案）

《新概念英语第二册》语法总结 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. （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,
