2、从句中作主语，宾语，表语，定语等，关系副词在从句中作地点状语，时间状语，原因状语等。 who, whom, that这些词代替的先行词是人的名词或代词，who作主语指人，whom作宾语指人，that既可作主语又可作宾语（作宾语可以省略），可以指人也可以指物。在从句中所起作用如下： (1) Is he the man who/that wants to see you? 他就是想见你的人吗？（who/that在从句中作主语） (2) He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。（whom/that在从句中作宾语） Whose 用来指

6、e, few, much等修饰时，这时的that常被省略； c)先行词前有序数词或被形容词最高级修饰时； d)先行词中既有人又有物时； e)整个句中前面已有which，who,that时； f)当先行词为物并作表语时； g)先行词为one时； h)先行词同时又被the only,the very,the same修饰时； 4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语 5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与 of

7、 which 调换,表达的意思一样。 关系副词关系副词：在句中作状语 关系副词=介词+关系代词 why=for which where=in/ at/ on/ . which (介词同先行词搭配) when=during/ on/ in/ . which (介词同先行词搭配) 1. where是关系副词，用来表示地点的定语从句。 2. when引导定语从句表示时间注值得一提的是，表示时间“time一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。 By the time you arrived in London, we had stayed there for t

26、行词 定语从句修饰先行词 判断介词和关系代词方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。不及物动词后面无宾语，就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语，则要求用关系代词。例如： This is the mountain village where I stayed last year. Ill never forget the days when I worked together with you. 判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。） （错） This is the mountain village where I visi

27、ted last year. （错） I will never forget the days when I spent in the countryside. （对） This is the mountain village (which) I visited last year. （对） Ill never forget the days (which) I spent in the countryside. 习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。 方法二： 准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出

28、关系代词/关系副词。 例1. Is this museum _ you visited a few days ago? A. whereB. thatC. on whichD. the one 例2. Is this the museum _ the exhibition was held? A. whereB. thatC. on whichD. the one 答案：例1 D，例2 A 例1变为肯定句： This museum is _ you visited a few days ago. 例2变为肯定句： This is the museum _ the exhibition was

29、held. 在句1中，is后应跟表语，只有the one可以，而后面的you visited a few days ago则做one的定语从句。 而句2中, 主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum词组，可用介词in + which 引导地点状语。而此题中，介词on 用的不对，所以选A。 关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词 (who, whom, that, which, whose)； 先行词在从句中做状语时，应选择关系副词 ( where 地点状语，when 时间状语，why 原因状语)

30、 。 先行词和关系词1)Whoever spits in public will be punished here.(Whoever 可以用 anyone who 代替) 2)The parents will use what they have to send their son to technical school. (what 可以用all that代替) 但这两句句子已经不是定语从句了，是名词性从句。因为定语从句一定要有先行词，而名词性从句没有。将“Whoever”、“what”分别用“Anyone who”、“all that”代替后，才是定语从句，先行词分别是“Anyone”、“all”。 由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。 As we know, smoking is harmful to ones health. The sun heats the earth, which is very important to us. 典型例题 1）Alice received an invitation from he
