同位语从句和宾语补足语之间有什么不同

定语从句与同位语从句的区别
定语从句与同位语从句相似的位置,使许多学生往往混淆.如何正确地区分定语从句与同位语从句呢?
一、 定语从句是形容词从句,其作用相当于一个形容词,是用来修饰前面的名词或代词的；同位语从句是名词从句,其作用相当于一个名词,是对前面的名词作进一步解释的.例如：
1． We heard the news that he had told her.我们听到他对她说的消息.2． We heard the news that he had won the game.我们听到消息他赢得了比赛.
例1中的that从句的作用相当于一个形容词,其作用是修饰the news；例2中的that从句的作用相当于一个名词,是对the news的进一步说明.
二、定语从句的引导词在从句中充当一定的成分,可作主语、宾语、状语等；而同位语从句中的引导词在从句只起连接作用,不作任何句子成分.例如：
1.A plane is a machine that can fly.飞机是一种能飞的机器.
2.The fact that they didn't finish the work has to be faced.必须面对事实,他们没有完成工作.
例1中的引导词that在从句中充当句子成分,作从句的主语,故为定语从句；例2中的that只起连接作用,引导从句解释fact的内容,不作任何句子成分,故为同位语从句.
三、同位语从句与其所修饰的名词之间是一种同位关系,二者之间存在逻辑上的系表关系,可用“主+系+表”结构来表示.例如：
The news that he won the first place is true.他赢得冠军的那个消息是真的.上句若用“主+系+表”结构来表示,则是：
The news is that he won the first place.消息是他赢得了冠军.
四、由when,why,where引导的定语从句分别修饰或说明表示时间、原因或地点的词,但它们引导的同位语从句一般不和表示时间或地点的词同位.例如：
1.I still remember the day when I first came to Beijing.我仍然记得初次来北京的那天.
2.I have no idea when she will be back.我不知道她何时回来.
3.This is the house where I lived two years ago.这是我两年前住的房子.
4.The question where we shall have a meeting hasn't decided.我们到什么地方去开会,这个问题没有决定.
例1、3中的when和 where引导的是定语从句,day 和house分别表示时间和地点；例2、4中的when和 where引导的是同位语从句.
定语从句和同位语从句的区别
定语从句和同位语从句是英语中两种比较重要且常用的从句,在历届高考中容易出现.而这两种从句有一定的相似性,不少学生难以分清,常常误用,高考中失分较多.现将这两种从句的区别浅析如下,以帮助那些使用这两种从句有困难的学生.一、从语法功能和概念上辨别 定语从句是形容词性的从句,是对前面名词的性质、特征进行描述,它与先行词（前面的名词）是修饰与被修饰的关系：而同位语从句是名词性从句,是对前面名词作进一步的补充性解释说明,它与前面的名词是同位关系,即前面名词是从句的概括总结,从句是前面名词的具体内容,且名词与该同位语从句有逻辑上的主表关系.如：①.I will tell you piece of news that you may not have heard.
②.The news that he had won the first prize in the competition made us very happy.
 ①句中的 that 从句是对 news 起修饰和限定作用的,所以该句为定语从句.②句中
的 that 从句是对 news 的内容做解释说明,且 news 与 that 从句在逻辑上是主表关系,可以说 The news was that he had won the first prize in the competition.所以该句为同位语从句.二、从先行词上辨别
定语从句的先行词没有限定,举不胜举：而同位语从句的先行词仅限于具有一定内容的抽象名词,如：idea （想法,主意）、 news （消息）、 answer （答复）、 fact （事实）、 hope (希望)、 thought (想法)、 belief (信仰)、 message (信息)、 possibility (可能性)等.三、从引导词上辨别
引导定语从句的 that 为关系代词,在从句中充当主语或宾语,指物时可用 which 替换,当它在定语从句中做宾语时可以省略；而引导同位语从句的 that 为连词,在从句
中不充当任何成分,但不可以省略,且不能用 which 代替.如：
1．The news (that/which)he told me yesterday is not true.（定语从句）  2．The news that he will go to Beijing is not true.（同位语从句）  3．At the meeting he expressed the hope (that/which)we wanted to express.（定语从句）  4.At the meeting he expressed the hope that he wanted to go abroad to further study.（同位语从句） 四、从语气上辨别
从句位于少数几个名词,如 suggestion,advice,order,request 等后时,同位语从句的谓语动词必须用虚拟语气,既 should ＋动词原形,should可以省略;而定语从句则没有这一要求.如：
 The advice that we (should) build a school in that small village was supported by all of us.（同位语从句）
 The advice that he gave was supported by all of us.（定语从句）

看that在从句中是否作成分,做成分是定语从句,只连接句子是同位语从句.如The news that I've just got is ture.that做got的宾语,定语从句.The news that she has come back is true.that后面对news的解释,同位语从句

同位语从句与宾语从句区别很明显...
同位语从句是在名词后加上关系副词的,作进一步解释或叙述．
宾语从句是在没有宾语的前提下,加上关系副词,充当句子的宾语成分．
我来造个句子：
News came that Bush was criticized by his assistant.
News came 已经独立成句,而后面是补充说明News的
I wanted to tell you that Bush was criticized by his assistant.
I wanted to tell you sth.tell要求双宾语,所以缺一个宾语呀,that ...就充当宾语

同位语从句用于解释说明前面的名词.如：
The fact that the earth is round is true.地球是圆的的事实是真实的.（that从句用于解释说明the fact）
定语从句相当于一个形容词,用于修饰前面的名词.如：
The student who answered the question was John.回答问题的学生是John.
状语从句相当于一个副词,如：
When it rains,I usually go to school by bus.天下雨时,我通常坐公共汽车上学.（时间状语）
If he comes tomorrow,you will see him.如果他明天来,你就可以看见他.（if 引导的条件状语从句,其结构为：if +状语从句,＋主句）.要注意在状语从句中有一个规则是“主将从现”,即主句是将来时,则从句要用一般现在时表示将来.
主句和从句的划分方法是相同的.句子的成分从谓语动词处来划分比较容易.谓语动词前面的部分是主语,后面常接宾语,修饰谓语动词的是状语,修饰主语、宾语的是定语,若谓语是系动词,则系动词后的部分是表语.如：
I am a teacher.其中,I 是主语,am是谓语,a teacher 是表语.
He likes playing football very mucy.其中,he是主语,likes是谓语,playing football是宾语,very much是状语.
定语从句
1.引导定语从句的关系词有who,whom,whose,that,when,where,why and which.在非限制定语从句中,只可用which,who,whose,where ,when.,如果指代前面整个句子,多用which.
2.当引导定语从句的先行词前有all,any,no,little,much,very first 等词,或先行词前为形容词最高级所修饰时,或先行词为all,anything,nothing,something,everything 时,从句的引导词只能用that.
3.as 可做引导词引导定语从句,多和such,the same 连用.As 引导的定语从句也可修饰整个句子,既可放在先行词后,也可放在句子开头.
4.介词+which/whom/whose从句
5.代/名+介词+which 从句
6.同位语从句和定语从句
三 状语从句:
修饰主句中的动词,形容词和副词,通常有从属连词引导,按其意义和作用可分为时间,地点,条件,原因,让步,目的,结果,方式,比较.等
1.时间状语从句:
1) 常见连词有 after,as,before,once,since,till,(not)until,when,whenever(no matter when),while,as long as,as soon as etc.

3) 还有 immediately,directly,instantly,the moment,the minute,the instant,the second,every time etc
2.地点状语从句:一般用where or wherever 引导
3.条件状语从句:真实条件从句:if,unless,so long as,provided that,supposing that,on condition that,in the event that,in case that etc
4.原因状语从句:从属连词有because,as ,since,for,now,that,in that,seeing that,considering that(鉴于,由于)
5.让步状语从句:
1):even if,though,even though,while(尽管) no matter what/how/which,however,whatever,whichever,however etc.
2) 由as 引起的让步从句,语气较强烈,被强调的词须放在句首.
3) whether…or,不管…或…
6.结果状语从句:so that,so…that,such…that
7.目的状语从句:so that,in order that,for fear that,lest,in case
8.方式状语从句:as,just as,as if:如同…一样
9.比较状语从句:
1) as…as,not so/as…as
2) 比较级+than,so much/a lot more than
3) no more…than,not more…than,less…than
4) the more…the more
英语从句是一个很复杂的语法,不可能简洁又明了的概述,我这里只有它的基本结构和用法,你应该去看语法书,那里面有较详尽的解释,还有例句,还可以去一些英语学习的网站,如果你以前没有学英语从句的话,就这样看看它的基本结构和搭配,是不可能完全掌握和理解它的

定语从句是形容词从句,其作用相当于一个形容词,是用来修饰前面的名词或代词的；
同位语从句是名词从句,其作用相当于一个名词,是对前面的名词作进一步解释的.
例如：1． We heard the news that he had told her.我们听到他对她说的消息.
2． We heard the news that he had won the game.我们听到消息他赢得了比赛.
例1中的that从句的作用相当于一个形容词,其作用是修饰the news；例2中的that从句的作用相当于一个名词,是对the news的进一步说明.

由 that 引导

同位语从句解释说明前面的名词,与名词构成主表结构

在复合句中用作同位语的从句叫同位语从句.它一般跟在某些名词后面,用以说明该名词表示的具体内容.This is because they come from a computer program called ICQ,which means I seek you.这句中是非限定性定语从句,因为第一,根据第二条,它构不成主系表结构,第二,从句起修饰的作用 定语从句与同位语从句在形式以及它们在句中的位置上都很相似,但它们在句中的句法功能不同,所用的引导词也不完全一样.1.定语从句是形容词从句,其句法功能相当于一个形容词,与前面的名词是修饰与被修饰关系,即限定它前面的名词范围,或补充一些情况；而同位语从句是名词性从句,其作用相当于一个名词,与前面的名词是同位关系,是对前面的名词作进一步解释,即说明它前面名词的内容.如：The news that he told me just now is true.他刚才告诉我的消息是真的.（定语从句） The news that I have passed the exam is true.我通过了考试这一消息是真的.（同位语从句） 2.同位语从句与其所修饰的名词之间是一种同位关系,二者之间存在逻辑上的系表关系,可用“主系表”结构来表示,而定语从句则没有这种关系.如：The news that he won the first place is true.他赢得冠军的消息是真的.（同位语从句） 若用“主系表”结构来表示,则是：The news is that he won the first place.那个消息是他赢得了冠军.3.定语从句的先行词可以是各类名词,而可跟同位语从句的名词通常只是 news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,possibility 等少数几个.因此,引导两种从句的连接词也不完全一样.可以引导定语从句的连接词有 that,which,who,whom,whose,when,where,why 等.可以引导同位从句的连接词有 that,whether,when,where,how 等.如：The factory which / that we visited yesterday is a chemical one.我们昨天参观的那家工厂是化工厂.（定语从句） I’ve come from Mr Wang with a message that he won’t be able to see you this afternoon.我从王先生那里得知一个消息,他今天下午不能来看你了.（同位语从句） 4.定语从句的引导词在从句中充当一定的成分,可作主语、宾语、状语等；而同位语从句中的引导词在从句中起连接作用,不作任何句子成分.如：The idea that he gave surprises many people.他提出的观点令许多人感到吃惊.（定语从句,that 在从句中作 gave 的宾语） The fact that they didn’t finish the work has to be faced.必须面对事实,他们没有完成工作.（同位语从句,that 在从句中只起连接作用,引导从句解释 fact 的内容,不作任何句子成分） 5.引导定语从句的连接词有时可以省去,而引导同位语从句的连接词则不可省去.如：I’ll keep the promise （that / which） I made two years ago.我将履行两年前许下的诺言.（定语从句） I make a promise that I will write to you as soon as I get to Beijing.我许诺,我一到北京就给你写信.（同位语从句） 6、若连词为特殊疑问词,根据从句是否有疑问的意义判断.如：eg.Do you remember the day when i told you that i loved you?(when引导的从句不表示疑问,所以这是一个定语从句.） eg.I have asked the question why it was true just now.(why引导的从句表示疑问,所以这是一个同位语从句.） 这些我也看不懂.

同位语从句一般只用that引导,不像定语从句可以用诸如which,that,who,whom,whose,介词+which,等很多词引导.同位语从句和定语从句的区别就在于定语从句是对前面词语的修饰,而同位语从句是对前面词语的补充解释说明.

.同位语从句是指在复合句中跟在名词后面,充当名词的同位语的从句,它是对前面的名词起到解释和说明的作用.同位语从句常位于news,idea,fact,thought,problem,answer,belief,possibility,plan,suggestion,promise,teport,question,truth,proof,order,hope,information...等的名词后面.例如：
1、The news that the famous singer will come to our city is not true.
那位著名的歌星将要到我们市的消息是不真实的.
（其中that引导的同位语从句只是对名词The news的内容进行解释.）
2、She made a promise that she would give me a present on my birthday.
她许下诺言在我生日的时候将送我一份礼物.
（其中that引导的同位语从句只是对名词a promise的内容进行解释.）
3、I have no idea when he will come back.
我不知道他什么时候回来.
（其中when引导的同位语从句只是对名词idea的内容进行解释.）
4、The question who should come with me has not been settled.
谁将和我一起去这个问题还没解决.
（其中who引导的同位语从句只是对名词The question的内容进行解释.）
同位语从句的引导词有：
that,whether,who,when,where
其中that只起到引导从句的作用,它在从句中不充当任何成分,没有意义,但也不能省略.

定语从句的功能是一个句子当一个形容词来用 中文中也很常见
比如:他喜欢那个(带着耳环的)女人.
He likes the woman (who is wearing rings).
主语从句的功能是一个句子当做主语来用
比如:(我爱的人)不爱我.
(Whom I love) doesn't love me.
同位语从句的功能是用另外一种方法来表示一个词,与那个词用逗号分开,如果后面还有未说完的内容的话也是用逗号分开
比如:I love Marry,a 18 year-old-girl.(a 18 year-old-girl=Marry)
My teacher,Blue,is 30 years old.(teacher=Blue,此处由于只有一个单词逗号实际是可以省略的)
简单的说同位语从句是用来给更多的细节的(descriptive details)

定语从句:attributive clause
同位语从句:appositive clause
先行词:an antecedent
引导一个从句:to lead a clause

The doubt that whether she passed the exam will soon be clear.
这里是同位语
Any doubt please feel free to contact
这个就不是了

例1：I have no idea when he will be back.　　析：he will be back意义不完整，应加“什么时候”的含义才能表达idea的全部内容，因此应用when引导同位语从句。　　例2：I have no impression how he went home，perhaps by bike.　　析：he went home意义不完整，应加“如何”的含义才能表达i...

that是连词 when是连接副词,that在从句中无词义,且不起任何成分作用 ;when指何时,做时间状语.
同位语从句是名词性从句（主语从句、表语从句、宾语从句、同位语从句,介宾从句）中的主要从句之一,从句作同位语表示与之同位的名词（短语）的实际内容,它的作用相当于名词,对前面的名词（短语）加以补充说明或进一步解释,相当于一个表语从句,它们之间的关系是同位关系,即主表关系,所以不缺主语和宾语.

是同位语从句,判断同位语从句和宾语从句的区别是,同位语从句是对前面的同位语（that前面的名词）作为内容的补充,并且这个句子是个完整的句子,在这句话中news的内容是他被杀了,所以是同位语从句.
而宾语从句通常是放在谓语动词或者介词后面,作为句子的宾语.

主语从句：简单地说就是一个句子是主语.引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等.例句：What I say is right.我说的都是对的.如果是动词作主语的话要加上to或者-ing.
宾语从句：在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句.连接词一般都是that(指事务或人),which（指事）,who（指人）.
例句：The teacher told the children that the sun is round.这里需要注意时态.因为太阳是圆的是不可争的事实,所以主句的动词用is.
还有就是注意虚拟语气.
定语从句是由关系代词或关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,相当于形容词,所以又称为形容词性从句.关系代词有that,which,who,whom,whose,as等,绝对没有what；关系副词有where,when,why等.that引导的定于从句要跟同位语从句要区分.定于从句记住一定是要做成分的,而同位语从句不做成分.
eg: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）
状语从句可分为：时间状语从句；地点状语从句；原因状语从句；条件状语从句；目的状语从句；让步状语从句；比较状语从句；方式状语从句；结果状语从句.状语的位置比较灵活,可以位于句首、句末或句中.enough用作状语修饰形容词和副词时必须后置.由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难.
eg:While John was watching TV,his wife was cooking.时间状语从句
表语从句：用作表语的从句叫表语从句.引导表语从句的关联词与引导主语从句的关联词大都一样.表语从句一定要用陈述语序.不可以用if,而用whether 连接表语从句(as if 例外）.位于句首时要用whether.that在表语从句中不可以省掉.
eg:The question is when he can arrive at the hotel.
同位语从句是名词性从句中的主要从句之一,它一般跟在某些名词后面,用以说明该名词表示的具体内容.可以跟同位语从句的名词通常有news,idea,fact,promise,question,doubt,thought,hope,message,suggestion,words（消息）,possibility等.引导同位语从句的词通有连词 that,whether,连接副词 how,when,where等.（注：if,which 不能引导同位语从句.）
eg:He must answer the question whether he agrees to it or not.他必须回答他是否同意这样一个问题.
给分吧!

不是同位语 也不是定语从句 是强调句型
参考：
结构是：It+be+被强调部分+that+从句 　　
强调主语：It is the times that produce their heroes.时势造英雄 　　
强调宾语：It is English that Prof.Lin teaches us. 　　
强调状语：It was in shanghai that I saw the film. 　　
判断是否是强调句有一个方法,就是将that以后的“句子的其余部分”拿出来单独看,看有没有缺成分,缺的是什么成分,再把谓语动词后面that前面的那部分,带到你认为缺成分的地方,如果放进去是一句完整的句子了,那就说明是强调句.

引导同位语的引导中没有which,除非是定语从句.

这是一个定语从句.先行词是custom. 这是一个特定语境的先行词.关系词只能用where.这也是高考中常见的考点之一.类似的先行词有point,case,situation,business,chair,climate,occasion等.不能用that替换.不是同位语从句.

例如：The media can often help solve problems and draw attention to situations where help is needed.

同位语从句和定语从句都是针对名词的,首先看同位语从句,一：同位语的名词后面加个be动词能跟后面的句子重新构成完整的句子,二：从句本来就是个完整的句子,如下例举说明：
例句是They were all worried over the fact that you were sick.
第一,加be后为The fact is that you were sick.这仍然是一个句子.
第二,You were sick.本来就是一个完整的句子.
下面看定语从句,则和同位语从句不一样,它需要加上先行词才能是完整的句子成分,但是仍然不是一个完整的句子,下面例句说明：
例句是He is the man that I saw yesterday.
that I saw yesterday可以是完整的句子成分,即主谓宾都有,但仍不是一个句子,因为不符合语法顺序,它把宾语提前了,看出来了吗,同学?正确顺序为主谓宾,即 I saw that testerday.当然that 不能作宾语,此处只是为了给你说明一下顺序.
总结如下：1.不论是宾语从句还是同位语从句,前半个句子也就是主句都是完整的,如例句中的They were all worried over the fact 和He is the man .
2.同位语从句去掉引导词that仍然为完整句子如you were sick,所以结构为句子+引导词+句子=同位语从句；对于定语从句,引导词+后面的成分是完整的句子成分,只不过是宾语提前了而已.

第一个THA是同位,第二个THAT 是表语从句

that在引导宾语从句 ,可以省略.
eg：he said (that) he was a student.
主语从句我很少见that引导,一般为what,不能省略.
what he said was a good idea.
what he said是一个主语从句.
that引导同位语从句时,不能省略.
I can't stand the terrible noise that she is crying loudly.
she is crying loudly是一个完整的句子,并不是一个修饰语,它the terrible noise的内容,两者都是指一个东西.
that引导定语从句时,可以省略.而which 只有在做宾语时可以省略,其余不能省略.
she wa dressed in a bezutiful skirt (that) was printed two tigs.
was printed two tigs 是用来修饰a bezutiful skirt,做其定语的.
其实以上都可以称之为关系代词,只是搞清楚其用法非常重要,最长考的是定语从句,其次是同位语从句,宾语从句有时候也有,主语从句主要是考what,

定语从句 是对前面的名词起限定作用（也有非限定的） 定 就是限定的意思 定语从句的的关系词 在定语从句中要充当 句子成分 that引导的定从 that是关系代词 在定从中作主语 宾语或表语.如the news that his father died made him sad.他爹死的消息 使他伤心.这是同位语从句 消息 和他爹死 指的是一回事 他爹死 就是消息本身 that后面的从句 句子完整 the news that he told me made me sad.他告诉我的消息使我伤心 .这是定语从句 消息 和他告诉我的 是限定关系 说明消息是他告诉我的消息 而不是从别处得到的消息.that从句中缺直接宾语 故that作从句中told 的直接宾语你的第二个问题不需要回答 同位语在句子中 就是同位语 同位语本身就是一种句子成分

主语从句：What we need now is time.我们现在需要的是时间.
宾语从句：He suggested that the law should be changed.他建议那条法律条文应该修改.
表语从句：The problem is whether he will come.问题是他会不会来.
同位语从句：The fact that he was ill worried his parents .他生病的事实让父母很担心.

在复合句中充当同位语的名词性从句称为同位语从句.
同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一,从句作同位语表示与之同位的名词(短语)的实际内容,它的作用相当于名词,对前面的名词(短语)加以补充说明或进一步解释,相当于一个表语从句,它们之间的关系是同位关系,即主表关系.

先举一个例子给你.
I got a news that he would come
I got a news that made me very happy.
看出区别了吗?第一个是同位语从句,就是对前面news 的一个补充说明,而第二个例子则是对news的修饰.区别就在这里了.

定语从句中的that能省略,定语从句中的that 做宾语时可以省略；同位语从句中的that不做成分,但不能省略.例句：The news that I heard of is true. （定语）/The news that he won't be back is true. （同位语）

这也是我以前比较困惑的
同位语从句是对前面名词的内容作进一步的解释、说明,引导词只起引导作用,不在句中作任何成分,一般不可省略.定语从句是对前面名词进行修饰、限制,引导词在句中作一定的句子成分.
例如,
The news that they had won the game soon spread over the whole school.
他们赢得比赛的消息很快就传遍了整个学校.
（此句含同位语从句,进一步解释"the news”的内容）
The news you told me yesterday was really disappointing.
你昨天告诉我的消息真的很令人失望.
（此句含定语从句,它指的是“你昨天告诉我的那个消息”）

同位语从句中的what只是引导词,没有实际意义.

一样的,举个例子:
同位语从句:
I knew the reason why he came late. 当时我知道他来晚的原因
宾语从句也必须用过去事态
I knew (that) why he came late .that 可以省略

同位语从句和定语从句的区别是：
关系代词在从句中成分的是定语从句（that做主语或宾语）,不做成分的是同位语从句（就是主谓宾齐全,that引导从句）.
The news that our players won the gold medals is reported~that引导同位语从句.从句中主谓宾齐全.
The man who is a police have done sth
who在从句中做主语.

1 The news that we have won the match is true.
2 The question where we will have our holiday hasn't been decided yet.
3 The following question what steps we will take is unknow.
4 I have no idea why he is so rude.
5 The question whether it is right or not is uncertain.
6 We all know the truth that The earth travels around the sun.
7 He made the promise that if someone set him free,he will make him weathy.
8The news came around that his elder brother had joined the army.

1.同位语从句中,that一般不和前面句子隔开,而是直接放在所修饰的名词后面 （参考同位语从句定义：在复合句中用作同位语的从句叫同位语从句.它一般跟在某些名词后面,用以说明该名词表示的具体内容.如：
I heard the news that our team had won．我听到了我们队获胜的消息.
I had no idea that you were here．我不知道你在这里.
另：可以跟同位语从句的名词通常有new,idea,fact,promise,question,doubt,thought,hope,message,suggestion,word（消息）,possibility等.I’ve come from Mr wang with a message that he won’t be able to see you this afternoon． 我从王先生那里来,他让我告诉你他今天下午不能来看你了.）
2.这句话中,it是形式主语,that从句是真正主语,而不是充当同位语从句.

同位语从句和定于从句区分：
在定语从句中像that,which等一些的连词经常在从句中充当一些成分,比如主语,宾语等等,如果去掉它们则从句会变的不完整,即缺少成分.相反地,引导同位语从句的that在从句中不充当任何成分,即使去掉,也不会影响句子的完整性（不过千万不能去掉）.
这样分析的话,在这句话中,没有缺少成分.所以不能用when

同位语从句先行词常为一些体现一定内容的名词,如,idea,plan,promise,hope,fact,news,problem,truth,information等,这些词在同位语中不充当句子成分.

推荐的答案太罗嗦,我认为nmyzhjsh回答的比较简单明了,我可以帮你搞通语法,我是英语老师,擅长语法.我觉得你的语法还可以,不难超越.

一般来说,容易和同位语从句相混淆的就是定语从句.
你可以这样来判断二者的不同：
在定语从句中像that,which等一些的连词经常在从句中充当一些成分,比如主语,宾语等等,如果去掉它们则从句会变的不完整,即缺少成分.相反地,引导同位语从句的that在从句中不充当任何成分,即使去掉,也不会影响句子的完整性（不过千万不能去掉）.

语法讲一千遍过后的结果往往不是学生更加明白而是更加的糊涂.
语法的学习首先要知道什么时候用这个语法项目以及在什么地方用这个语法项目.
时态往往和说话人的主观表达意图有很大的关系,如进行时会让你的描述生动形象,完成时富含深层次的含义甚至于感情,一般式往往只是毫无目的的简单直陈.
语态其实在汉语中也一样存在,记得小学时候的被动句式和把字句式吗?那就是被动语态和主动语态.
主语从句、宾语从句、表语从句和同位语从句都是名词性从句,说得简单点,这些从句都相当于一个名词,可以当做名词来进行使用.但是所有的从句,不管是定语从句,状语从句还是名词性从句,他们的前面都会有一个连接词,如which, what, when, where,how等等,连接词后面紧跟的往往是一个主谓结构（俗称陈述句语序）.
语法题解题的主要技巧还是要把每个题目当做阅读理解来做,要体会说话人的表达意图,了解其感情色彩,这样才会选择恰当的表达方式.
内容太多,真要讲清楚恐怕至少也得万把字,只能如此了.

高考英语话题作文：有关“信心与希望”
　　例：1、生活中困难不可避免,面对困难需要信心…
　　　　2、试举一例说明信心在学习(考试、生活等)方面的作用…
　　　　3、你对困难的态度…
　　It is well-known that we exist in a dynamic world with various difficulties. When we are faced with them, nothing is more important than hope and self-confidence. With confidence, we can find sometimes the question is not as “huge”as we imagine.
　　Take most of us for example, the entrance exam to college seems to be a horrible monster. Accordingly, some people give up, some persist. In my eyes, with confidence, right assessment of the difficulties, as well as full preparation, try and exert your strength, and then we will overcome all problems and challenges. On the whole, I believe we youngsters should face the difficulties in right manner. And nothing is impossible, brave it out and just do it!

不一样,是得,前面是表从,后面是同位语从,前面译为事实是...,后面译为...这个事实.
如：I don't love you.The fact is that I love your brother.我不爱你.事实是我爱的是你哥.
The fact that she doesn't love me breaks my heart.她不爱我这个事实伤透了我的心.

但是,定语从句前有相应的先行词,分别为表示时间、地点和原因状语的名词,而（注：if,which 不能引导同位语从句.）如：l have no idea When he

定语从句限定范围,同位语从句说明内容.
the news he told me.(定语从句）
the news that our class won the game.（名词性从句）

xx从句就在这个句子在整个句子当中充当xx成分.定语就相当于一个形容词,起到修饰,限定的作用.所以定语从句就是修饰被修饰词.没有宾补,谓语从句的,因为一个句子不会充当得这些成分.

是定语从句
其中,省略了
in which ,that 或者 / ：
1 I don’t like the way that he teaches English
2 I don’t like the way / he teaches English
3 I don’t like the way in which he teaches English
