中考语法知识点总结 之各种从句 I．要点 　根据从句在句中的句法功能，从句可分为名词性从句、定语从句和状语从句。 1、 名词性从句 （1） 主语从句 　What he wants is a piece of paper. 　It is believed that he can solve the problem. 　注：主语从句的谓语动词用单数。 （2）宾语从句 　I don't know how to solve the problem. Do you know where he lives? （3）表语从句 　The problem is who can help me. 　This is why I came here. （4）同位语从句 同位语从句用that引导，常跟在fact, idea, news, promise, thought, message, hope, belief, doubt等词后，that在从句中不作任何成分。 I have no idea where he went. I heard the news that he would come. 2、定语从句 　在复合句中，修饰某一名词或代词，或修饰整个主句的从句叫做定语从句，引导定语从句的关系代词有who, whom, whose, which, that, as,和关系副词when, where, why。 （1）that指物时一般可与which互换，但在下列情况下，要用that而不用which。 　a. 先行词有all, everything等不定代词时，如， 　Everything (that) he did is wrong. b. 先行词被all, every, no, some, any, little, much等修饰时，如， 　I'll read all the books (that) you lend me. c. 先行词被序数词或形容词最高级修饰时， 　This is the first letter (that) the boy has written. 　d. 先行词被the only, the very, the same, the last修饰时， 如: 　He is the very man (that) I'm looking for.
