(4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分 概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy.

as might be excepted, as is often the case, 一般不能用which代替as。 c、在从句中作主语时，which既可作系动词be的主语也可作实义动词的主语，而as只可作系动词be的主语。 3、but用作关系代词，相当于who/that…not 例：In China there is no one but knows Lei Feng. 二、只用that不用which的情况 1、.先行词为 all , much, everything, nothing , something ,anything, nothing, none, the one等不定代词时 2、先行词被only, any, few, little, no , all, just , very ,right等修饰时. 3、当先行词是最高级或被形容词最高级修饰时。 4、当先行词是序数词或被序数词修饰时。 5、当先行词是数词时. 6、当先行词既指人又指物时。 7、如有两个定语从句，其中一个关系代词已用which，另一个关系代词则宜用 that。

高中英语语法系列：定语从句 知识要点 1.关系代词和关系副词的选用 2.限制性定语从句和非限制性定语从句的区别 3.几组的关系词特殊用法 一、定义：在复合句中，修饰名词或代词的从句叫做定语从句。 The happy man who lives next to me sells vegetables. You must do everything that I do. 被定语从句修饰的词，叫先行词。比如上面两句中的man和everything. 引导定语从句的词，叫关系代词和关系副词。比如who,whom,that,which,wh ere,when,why等 关系词三重作用：①连接主从句；②指代先行词；③在定语从句中担任句子成分。 The man who lives next to me sells vegetables. 该句中，who lives next to me是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。 二、关系词 引导定语从句的关系代词有who,whom,which,that,whose,as等和关系副词w here,when,why等。关系代词和关系副词在定语从句中担任句子成分。

高考英语语法：关于“where”从句详解 来源：天星更新日期：2010-05-15点击：249 “where”是高考热点之一，命题中主要考查其在定语从句、名词从句和状语从句这三大从句中的使用。 (1)Those successful deaf dancers think that dancing is an activity where sight matters more than hearing. 句中where是关系副词，引导定语从句，在从句中做状语； (2)You are saying that everyone should be equal, and this is where I disagree. 句中where是连接副词，引导名词从句做表语，而本身在从句中做状语； (3)If you are traveling where the customs are really foreign to your own, please do as the Romans do. 句中where是从属连词，引导状语从句。 在回答有关where的题目时，往往会遇到这样两个难点： 一、定语从句中，“感觉不到”的where。 一提到where，我们往往都借其词义，想到“哪里”，无论是在工厂，在学校，在街道等等，都看得见，摸得着，例如： They will fly to Washington, ____ they plan to stay for two or three days. A. where B. there C. which D. when 答案A，这似乎是显而易见。“他们要飞往华盛顿，他们打算在那(华盛顿)待上两三天。”“在华盛顿”，使用where，有具体的地点。 不过再看一看下面的三个题目： （1）Later in this chapter cases will be introduced to readers ____ consumer complaints have resulted in changes in the law. A. where B. when C. who D. which

01 有关概念 由一个主句和一个或一个以上从句构成的句子叫做复合句。所谓主句，就是在复合句中起统领作用 的句子，它是全句的主体，通常可以独立存在；而从句则是复合句的一个句子成分，不能独立存在。 如： You’ll feel better after you take the pills. 吃完药丸后你会感到好一些。 The police learned that he wasn’t there at that time. 警察获知他那时不在场。 这两句都是复合句，第一句的主句是You’ll feel better，从句是after you take the pills，由after 引导，在整个复合句中用作状语，表示时间；第二句的主句是The police learned是主句，that he wasn’t there at that time是从句，由that引导，在整个复合句中用作宾语。 注意，英语的复合句不是简单句的反面，不要将它误解为“复杂句”。事实上，英语的简单句有时 也可以比较“复杂”，而复合句也可以比较“简单”。如： He stopped because he was tired. 他停下来是因为他累了。 这个句子比较“简单”，却是一个典型的复合句，其中的he stopped是主句，because he was tired 是从句，在复合句中用作状语，表示原因。 02 从句的分类 前面我们说到从句是整个复合句的一个句子成分，它可以用作主语、宾语、定语、状语等。一般说 来，一个从句在复合句充当什么成分我们就叫它为什么从句——从句在复合句用作主语，我们就叫 它为主语从句；从句在复合句用作宾语，我们就叫它为宾语从句；从句在复合句用作状语，我们就 叫它为状语从句；等等。 如： He answered that he knew nothing about it. 他回答说他不知情。 The trouble is that I have lost his address. 麻烦的是我把他的地址丢了。 He was rather pleased when he won that prize. 他获奖后相当高兴。 She was not in the train that arrived just now. 她不在刚到的那列车上。
定义 表语从句定义：在一个复合句中，从句作的是主语的表语成分。 A The problem is puzzling. 这个问题令人困惑 主语,连系动词,形容词作表语 The problem is when we can get a pay rise. 问题是什么时候我们可以得到加薪. 主语连系动词一个句子作表语---表语从句 B 连接表语从句的连接词有：that, what, who, when, where, which, why,whether,how.whoever，whomever，whichever ，whatever等 He has become a teacher. 他已经成为一名教师。 He has become what he wanted to be ten years ago. 他已经成为了他10年前想成为的。 She has remained there for an hour. 她曾在那里停留了一个小时。 She has remained where I stood yesterday for an hour. 她一直在我昨天站的地方站了一个小时。 His suggestion is good. 他的建议是好的。 His suggestion is that we should stay calm. 他的建议是，我们应该保持冷静。 The question is confusing. 这个问题令人困惑. The question is when he can arrive at the hotel. 问题是，他什么时候可以到达酒店。 Who will travel with me to Beijing tomorrow.谁与我明天将前往北京。 Why he cried yesterday. 昨天他为什么哭。 How I can persuade her to join us in the party. 我怎么能说服她加入我们的派对。 Whether the enemy is marching towards us. 是否敌人正向我们行进. 注意 A 表语从句一定要用陈述语序。 False: The question is when can he arrive at the hotel. Right: The question is when he can arrive at the hotel. B 不可以用if，而用whether 连接表语从句(as if 例外）。 引导宾语从句时可以互换if/whether 位于介词后要用whether

二．各种状语从句的简化方法： 1．以after和before引导的状语从句的主语若与主句主语一致时，从句等于after/before+doing sth.作状语。 例：After she sang，she left the rich man's house． = After singing，she left the rich man's house． 2．以as soon as引导的状语从句的主语若与主句主语一致时，从句等于on+doing sth.,作状语，此时的动词为非延续性动词。 例：Mary began to operate on the wounded soldiers as soon as he arrived at the village．= Mary began to operate on the wounded soldiers on arriving at the village．3．时间状语从句和条件状语从句的主语和主句主语一致时，有时可简化为不定式作状语。 例：She stopped when she saw her husband． = She stopped to see her husband． If you want to understand the farmers，you must go to the countryside． = To understand the farmers，you must go to the countryside． 4．结果状语从句和目的状语从句的主语与主句主语一致时，可以简化为不定式作状语；若两者主语不一致时，则应简化为不定式的复合结构作状语。 例：He was so tired that he couldn't go any further．= He was too tired to go any further． I came here so that I could ask some questions．= I came here(in order) to ask some questions． 5．以when，while引导的时间状语从句和以if引导的条件状语从句的主语若与主句主语一致时，从句等于when/while/if +doing sth.作状语，表示谓语动作发生在该状语动作的进行过程之中。 例：When he turned on the radio，he found it broken．= When turning on the radio，he found
