高考英语同位语从句详解
高考英语同位语从句详解这句话中的同位语从句是：that it’s better to expect nothing than to give everything and then be disappointed。
它用在名词knowledge（知识、认识）后面，对knowledge进行补充说明，即使我们知道不期望任何东西比全力以赴然后失望更好。
同样地，判断同位语从句的关键是看它是否对主句中的某个名词进行补充说明。
名词+修饰语+同位语从句接下来，我们看一个稍微复杂一些的结构：The ___.___相信我们可以被爱，就是相信我们的真实自我是可爱的，这种信念让我们有勇气成长。
匿名这句话中，同位语从句that we can be loved exactly as we are是由名词idea（观念、想法）和修饰语the idea（这个观念、这个想法）共同构成的。
同样地，它对名词idea进行补充说明，即我们可以被爱，这个想法让我们有勇气成长。
需要注意的是，同位语从句和修饰语之间有时候还会加上介词of，如上例中的the idea of that we can be ___。
这种情况下，同位语从句的位置可能会更靠后，但同样对名词进行补充说明。
名词+谓语+同位语从句同位语从句不仅可以跟在名词后面，还可以跟在名词的谓语动词后面，如下面这个例句：Her belief that she could never be loved was the only ___ happiness.Marilyn Monroe。
American actress她认为自己永远不会被爱，这是唯一让她远离幸福的东西。
___，美国女演员这句话中，同位语从句that she could never be ___跟在名词belief（信念、）的谓语动词was后面，对___进行补充说明，即她认为自己永远不会被爱，这个信念让她远离幸福。
需要注意的是，同位语从句跟在名词的谓语动词后面时，要注意主谓一致的问题。
英语语法10之同位语从句
一、同位语从句
3.在名词doubt之后的同位语从句，有两种情况： （1）doubt之后用whether引导。 举例：I have my doubts whether the boy can pass the entrance examnation. （2）no doubt之后用that引导。 举例：There can be no doubt that cancer can be cured by mankind in the near fuliture. ◎连词but that也可以引导同位语从句，通常用在“否定词+doubt/deny/question等 名词”结构之后。这时，but仅起强调作用，无否定含义，常可省略；有时可省略 that,而保留but。 举例：There is no question (but) that the four modernizations will be realized in China in the near future.
二、that引导的同位语从句和that引导的定语从 句的区别
1.同位语从句中的that是从属连词，在从句中不作成分；而在定语从句中的that是 关系代词，它要代替先行词，还要在句中作成分。 举例：The news that our director will go to America is ture.

一、同位语从句
把从句放在一个名词之后，以进一步说明该词的情况、内容实质，并与该 词处于同等地位，这种从句叫同位语从句。从句所说明的词叫本位词，多是表 示抽象的概念或表示一个问题的名词；从句和本位词之间不用逗号分开。
高三英语语法讲解同位语从句
同位语从句一、同位语从句的位置与定语从句的比较：1、同位语从句与定语从句一样，都是用在名词后面。
所不的就是：定语从句是修饰限制它前面的名词，因此，它是属于形容词从句。
而同位语从句属于名词性从句，它是用来说明它前面的名词内容的，或者说是解释前面名词的内容。
2、同位语从句只用that作为开头（I have no idea除外），属于连词，在从句中不起成分作用，但不可省略。
而定语从句是以关系代词、关系副词开头，它们在从句中起句子成分作用（作主语、宾语、表语、定语或状语），作宾语时可以省略。
3、只有在内容方面可以进一步阐明的名词（一般为抽象名词）才能带同位语从句，而几乎任何名词都可以带定语从句。
比较：（1）The suggestion （that） she has given at the meeting is good.（2）The suggestion that she should stay in the room is good.（1）句中that she has given at the meeting这个从句说明了是她提出的建议，不是别人的建议，也就是限定了the suggestion的范围，但并没有说明建议的内容。
从结构上分析，that是give的宾语，所以这个从句是定语从句。
（2）句的that she should stay in the room这个从句说明了建议的内容，同时，that只起连词作用，在从句中既不是主语，也不是宾语，但不能省略，所以它是同位语从句。
二、同位语从句前常用的名词：同位语从句说明的名词常见的有：ability， advice， answer，belief， doubt，discovery， fact， fear， hope， idea， information， message，news， order，possibility， problem， proposal， question， story， suggestion， theory， thought，word（消息）等。
