8、子变成定语从句，就要把这句中相同的那个部分用一个关系词（即用一个关系词（即引导词引导词）来代替）来代替;(3)代替时，先看被代替的部分是指人还是指物、再看它作什么句成代替时，先看被代替的部分是指人还是指物、再看它作什么句成分。分。指人并作主语的，就用指人并作主语的，就用who。或。或that;指人并作宾语的，就用指人并作宾语的，就用who（常代替whom)，whom，或，或that,;指人并作定语的，就用指人并作定语的，就用whose。如何用定语从句把两个句子合二为一如何用定语从句把两个句子合二为一:指物并作主语的，就用指物并作主语的，就用which或或that指物并作宾语的，指物并作宾语的，

10、了。关系代词的关系代词的使用取决于先行词，它们的关使用取决于先行词，它们的关系非常密切，因为关系代词在定语从句中代系非常密切，因为关系代词在定语从句中代替主句中的先行词，所以它在一般情况下都替主句中的先行词，所以它在一般情况下都跟在先行词之后，而且它的跟在先行词之后，而且它的人称、数必须和人称、数必须和先行词一致先行词一致。The woman that/who_(be)speaking at the meeting is my mother.Those who _(be)talking are my parents.isare 定语从句的辨认与使用定语从句的辨认与使用 思考步骤：思考步骤：（1

31、）。例如：The girl who is standing there is Mary.She is the girl who/whom I met that day.The doctor to whom she sent her frirend is very famous.注：为以下情况时，who不与that通用 a.先行词为one(s)/anyone/those时,用who.b.当先行词有较长定语时用who I met a foreigner in the street yesterday who could asked me questions in Chinese.c.一个句子中带有
32、两个定语从句，其中一个定语从句的关系代词是 that另一个用who.The boy that you met last night is the group leader who studies very hard.d.在there be 开头的句中用who(2)whose 是代词的所有格，即可代人，又可代物。I saw a woman whose bag was stolen.Please show me the bag whose cover is red.(3)that 只用于限定性定语从句中，介词后不能跟that，而跟which.His mother does morning exer
33、cises every day,which is good for her health.在限定性定语从句中，which和that都指物时，可通用。The picture that/which was drawn by Tom was nice.有些情况下，只能用that，而不能用which.o先行词是最高级形容词或它的前面有最高 级形容词时.o先行词是序数词,或它前面有一个序数词时.o主句已有疑问词who或which时o先行词既有人又有物时o先行词是all,much,little,something,everything,anything,nothing,none,the one等代词时o先
34、行词only,any,few,little,no,all,one of,the same,the very等词修饰时1.有两个定语从句,其中一个关系代词用which,另一个用that(4)which 在非限定性定语从句中，只用which，不用that.在限定性定语从句中，只用which，而不用that的情况。a.关系代词前有介词时 This is the hotel in which you will stay.b.如果有两个定语从句，其中一句的 关系词是that，另一句用which.Let me show you the book that I borrowed from the libra
35、ry which was newly open to us.（5）关系代词与介词 1.当介词放在关系代词前时，介词宾语只能用which代物，whom代人。且关系代词一律不能省略。例如：I want to find the pen with which I wrote that letter.2.介词在末尾时，可用that/which（代物），that/whom/who（代人）做介词的宾语，切这个介词宾语的关系代词往往省略。例如：The man whom/who/that/可省可省 he wants to see is in Shanghai.（6）关系代词的省略 1.条件：只在限定性定语从句中
36、可省略。2.情况：a.关系代词在从句中担任动词宾语时 b.在从句中做介词的宾语，且介词在句尾 例如：Here is the man that you have been looking for.c.关系代词在从句中做表语时 例如：Shanghai is no longer the city which it used to be.d.在there be句型中，先行词是way时，关系代词省略。例：I dont like the way(that)you talk to me.三、关系副词引导的定语从句o关系副词是用来引导定语从句的o作用：（1）在定语从句中替代先行词 （2）在从句中担任状语成分，
37、起副词和介词短语的作用 （3）起连接作用，把两个句子连接成为一个带有定语从句的主从复合句o关系副词：where/when/why.o各关系代词的用法：owhere的用法：表的地方，修饰场所、方位名词。This is the house.I was born in the house.=This is the house where I was born.先行词 关系副词 =This is the house which I was born in.=This is the house in which I was born.注：关系副词可等于”介词+关系副词“2.when的用法：表的时候，修饰
38、日子年代等名词。We will never forget the day when we joined the party.3.why的用法：表的原因，的理由。The reason why I called is to invite you to a party.注：区分与关系代词的区别，只要在定语从句中担任状语的，就是关系副词。四、由as引导的定语从句 as可作为关系代词和关系副词来引导定语从句。osuch as“像一样的”，“像之类”the sameas“和同样的 在着两个句型中，as是关系代词，其中such&same做定语，修饰主句的名词、代词，这个名词是这个定语从句的先行词，as在从句
39、中担任主、宾、表。例如：This is the same thing as we are in need of.Such people as you say are short now.2.such as such为代词，意思为”这样的人/物“，as修饰先行词such。例如：This book is not such as I hope.3.the sameas/the same that “用一个”as that都引导定语从句。意思几乎相同。但从句中省去谓语是必须用as.例如：She is the same age as you that you are.4.,as “有些”在这里，as引导
40、非限定性定语从句，相当于which引导的非限定性定语从句，有时可互换。例如：He is from Beijing,as/which they know from the way he speaks.五、注意事项1.what不引导定语从句 I want to give you what I have.(宾语从句）2.先行词被the same 修饰时，关系代词既可用that,也可用as.但意义不同，前者表示“同一的”，后者表示“同样的”。3.关系副词when/where/why其含义相当于on which/in which/for which等可交替使用。如：The day when/on which I met him first was May 1st.4.当先行词为专有名词或整个句子是世界上独一无二的名词时，一般用非限定性定语从句修饰。例如：The sun,which gives us light,is very big.
