6、句的关系代词的情况a.在there be句型中,只用that,不用which.b.在不定代词,如:anything,nothing,the one,all,much,few,any,little等作先行词时,只用that,不用which.c.先行词有the only,the very修饰时,只用thatd.先行词为序数词,数词,形容词最高级时,只用thate.先行词既有人,又有物时用that.f.先行词被all,any,every,no,some,little,much等词修饰时。6as,which引导的非限定性定语从句引导的非限定性定语从句由as,which 引导的非限定性定语从句，as和w
7、hich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 her boss,_came as a surprise.A.itB.thatC.whichD.he答案C.此为非限定性从句，不能用 that修饰，而用which.，it 和he 都使后句成为句子，两个独立的句子不能单以逗
8、号连接。况且选he句意不通。2）The weather turned out to be very good,_ was more than we could expect.A.whatB.whichC.thatD.it答案B。which可代替句子，用于非限定性定语从句，而what不可。That 不能用于非限定性定语从句，it不为连词，使由逗号连接的两个句子并在一起在英语语法上行不通。7as 和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：(1）as 引导的定语从句可置于句首，而which不可。(2）as 代
9、表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。（3）as 多用于下列句型：the sameas,suchas,asas,as is known,as we have knowAs we know,smoking is harmful to ones health.As is known,smoking is harmful to ones health.I have got into the same trouble as he(has).8介词介词+关系词关系词 1）介词后面的关系词不能省略。2）that前不能有介词。3）某
10、些在从句中充当时间，地点或原因状语的介词+关系词“结构可以同关系副词when 和where 互换。This is the house in which I lived two years ago.This is the house where I lived two years ago.Do you remember the day on which you joined our club?Do you remember the day when you joined our club?whose+n 表示所属关系，可变为表示所属关系，可变为n+of which/whom，表示部分关系时，也可
11、用表示部分关系时，也可用部分关系词部分关系词+of which/whom.The buses,most of which were already full,were surrounded by the angry crowd.91 定语从句与同位语从句定语从句与同位语从句 定语从句与前面的名词是修饰与被修饰的关定语从句与前面的名词是修饰与被修饰的关系系“的（名词）的（名词）”。而同位语从句是用来。而同位语从句是用来说明前面名词的内容。与说明前面名词的内容。与that从句同位的名词从句同位的名词必须是一些表事实或概念的抽象名词，如必须是一些表事实或概念的抽象名词，如fact,news,beli
12、ef,truth,reply等。等。that在定语从句中在定语从句中作成分作成分，可用，可用which 或或who/whom代替；而代替；而that在同位语从句中在同位语从句中不充当任何句子成分不充当任何句子成分，只起连，只起连接作用。试比较：接作用。试比较：易与定语从句混淆的其他复合句易与定语从句混淆的其他复合句10 We all have heard the news _ our team won.We dont believe the news _ he told us yesterday.that(同位语从句，同位语从句，that从句表示从句表示news的内容，的内容，that 在从句

16、断关系代词与关系副词判断关系代词与关系副词 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。及物动词后面无宾语，就必须要求用关系代词；而不及物动词则要求用关系副词。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（错）This is the mountain village where I visited last year.（错）I will never forget the days whe
17、n 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。15方法二：准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1.Is this museum _ you visited a few days age?A.wh
18、ereB.that C.on which D.the one例2.Is this the museum _ the exhibition was held.A.whereB.that C.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 held.在句1中，所缺部分为宾语，而where,that,on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可
19、以省略关系代词，所以应选D。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。16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，应选择关系副词先行词在从句中做状语时，应选择关系副词(where 地点状语，地点状语，when 时间状语，时间状语，why 原因状语
