Nun Clauses(名词性从句)
Subject Clause (主语从句)
Appsitive Clause（同位语从句）
Object Clause（宾语从句）
Predicative Clause（表语从句）
名词性从句在功能上相当于名词, 在复合句中能担任主语、宾语、表语、同位语等。
His jb is imprtant.
What he des is imprtant.
This is his jb.
This is what he des every day.
I dn’t like his jb.
I dn’t like what he des every day.
I dn’t knw abut the man, Mr. White.
I dn’t knw abut the fact that he is a teacher.
Wh will win the match is still unknwn. I want t knw wh will win the match . The questin is wh will win the match . The questin wh will win the match is interesting.
名词性从句的作用相当于名词，因此主语从句、表语从句 、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。
1。（根据句意）标出名词性从句并确定是①主从？②宾从？③表从 ？④同位从？
①缺主宾表定用连接代词
②缺状(根据句意判断是否需要补充状语）用连接副词
①需要“是否”含义whether或 if ?
②不要需要“是否”含义用that
What的用法（1）(有疑问语气）译为“什么”（2） (没有疑问语气）译为“……的人/事情/样子/时间/东西等”1。I dn’t knw____happened yesterday。 1。Tm is____we call a walking dictinary活字典 。2。___he did made us disappinted。 3。Zhengzhu is n lnger___it used t be。3. Jane is n lnger ___ she was ten years ag.4。After ___ seemed years, Tm tld us the secret。 5。Liuxiang has____it takes t be a prfessinal runner

Wh(侧重事情）,whever（侧重人）1.____will g there has nt been decided yet。2。______cmes will be welcme作定语Which(侧重“哪一个”）whse（侧重“谁的”只作定语) what (侧重“什么”）用What/which/whse填空1。 I dn’t knw ____ dictinary this is。2。 I dn’t knw ____(dictinary) belngs t yu3。 ____ jb he des is still unknwn
Object Clauses 宾语从句
1. I wnder if yu'd mind us asking a few questins.2. ... his eyes stare at what is left f the brthers' dinner n thetable.3. I'm afraid (that) it'll cst a large amunt f mney.
句子做宾语就是宾语从句，跟在及物动词、介词或系表结构后
宾 语 从 句
一、连词（引导词）that 1. that1) that在从句中不作任何成分，也没有任何具体意思，因此在口语或非正式文体中常省略。
Lin Ta feels (that) his wn team is even better.
2.在主句为动词be加某些形容词（如srry, sure, afraid, glad等）作表语时，后面所跟的从句也是宾语从句(that可省略)。
I’m srry (that) I dn’t knw .We’re sure (that) ur team will win .I’m afraid (that) he wn’t pass the exam .
3。宾语从句中的连接词that在以下三种情况下不能省略：
（1）当that 从句与另一名词性从句并列作宾语时，第一个that能省，第二个that不能省；（2）当that从句作介词宾语时，that不可省。（3）用it做形式宾语的宾语从句，that不可省。
The reasn lies in that she wrks harder than the thers d.I think it necessary that yu shuld read English alud.
We all think ____ she wrks hard and____ she will g t a very gd university.
二.注意 whether和if的使用区别:
1) whether和if都可以引导宾语从句，表示“是否”不能省略，但 以下情况只用whether,不用if。a. 当从句中有r nt时 b. 介词后面的宾语从句。 C.当与t d连用时，
I want t knw whether he will cme r nt .
Are yu talking abut whether he will cme ?
He desn’t knw whether t g.
1. I dubt ______________ he has cme2. I dn’t dubt____________ he has cme
whether/ if
三。关于dubt鉴于dubt自身含义的特殊性，在谓语动词dubt或be nt sure后用whether/ if引导宾语从句；在谓语动词dn't dubt或be sure后用that引导
四。时态1. 如果主句是现在的时态 ，从句的时态可根据实际情况而定
I knw he _______ English .(like) I knw he _______ English ten years ag .(like)
2. 如果主句是过去的时态，那么从句的时态一定要用相对应的______的某种时态
He asked whether his father _______________ tmrrw. (cme back)He said that he ________ it befre. (see)
3.当从句是客观真理，定义，公理，定理时用一般现在时。
He said the earth _______ arund the sun.（travel）
wuld cme back
五、语序宾语从句要用陈述语序：连接词+主语+谓语+其他成分。
1. I dn’t knw what is the matter / the truble/ wrng with him.2. I dn’t knw wh did it.3. I dn’t knw wh is he.
1. His brther asks when he will g t the library .2. His brther asks when will he g t the library .
We felt it strange that Xia Wang did nt cme yesterday.
六。注意：形式宾语it it常可以放在动词think, find, cnsider, believe, feel, make等后作为形式宾语, 真正的宾语是that/ wh-从句则放在句尾。
Predicative Clauses 表语从句
表语从句是在复合句中作表语的名词性从句,放在系动词之后,一般结构是“主语+系动词+表语从句”。可以接表语从句的系动词有be, lk, remain, seem等。
在表语从句中，表“是否” 时，只能用 “whether”不能用“if”。一般情况下，“that”不能省。 It is/ was because +原因 It is/ was why+结果 4. The reasn (why…/fr…)is/ was that….5. The reasn is because/ why…
1. The questin is _______ we can rely n him.2. He didn’t study abrad. That’s ________ he was in need f mney at that time .3. He lked _____ he was ging t cry .4. My car brke dwn halfway. That’s _____ I was late .
Subject Clauses 主语从句
1. ______the earth is rund is knwn t all. (地球是圆的)
一. that 只起引导作用，不充当主语从句中成分，没有意义，但_____省略。
二，whether “是否”，不做成分,不能省略。放句首只用whether ； It 作形式主语，真正主语从句放后面时if和whether均可引导主语从句。
____________ he will cme here is nt easy t say(他是否会来这儿）.
Whether（不用if)
It is nt easy t say__________he will cme here
Whether/if
What he needs __ that bk.What he needs ___ sme bks.
三。主语从句对应的主句谓语动词一般用单数。但what等引导主语从句时，主句谓语单复数可根据表语决定。
appsitive Clauses 同位语从句
同位语从句 1. 跟在某些抽象名词后面，对该名词作进一步解释说明。常用名词有belief, fact, idea, hpe, news, dubt, result, thught, infrmatin, pinin等。以及suggestin, rder, demand, wish等。
1. The news _______ we wn the cmpetitin is very encuraging.2. I have n idea ______ has happened t him.
用that/ what填空
1.the news (that)yu tld us yesterday is news that they wn the match is true.
3. 定语从句：充当宾语时可以省略。 同位语从句：that不能省
区别that引导的同位语从句和定语从句：
1.定语从句：that充当的主语或宾语。同位语从句：that不作任何句子成分
2.定语从句：对前面名词进行修饰或限定，译为“…的”。 同位语从句：对前面名词的内容的具体说明
判断:定语从句r同位语从句
1.The rder that we shuld send a few peple t help the ther grups was received yesterday. 2.The rder that we received yesterday was that we shuld send a few peple t help the ther grups. 3.The news that he will leave fr Shanghai is questin that we discussed yesterday is a difficult ne.
1。用_______ 语序2。在句中有表示_______，_______，_______，_______，_______等意义的词时，句中相应的名词性从句常用______________1.He suggested that we _______________hard at suggestin is that we_____________hard at we_____________hard at English is my accepted my suggestin that we_____________hard at English.
（shuld)+动词原形
（shuld) wrk
3。“n matter+疑问词”只能引导_____________状语从句特殊疑问词+ever 既可引导______________从句，也可引导____________状语从句_____________________ yu d,I'll supprt yu.I'll give yu ______________ yu want.
whatever/n matter what
