in the same way that people co

一句话概述您的困惑点，获得老师针对性解答in the same way that people communicate with spoken language, 请问是什么从句？同位语和定语从句怎么辨别？谢谢！

解题思路： 建议同学阅读有关语法书籍，把名词性从句的知识通读一遍，多做练习，在错误中加深对相关知识的了解掌握。
解题过程：
在教学中我发现，同学们区分同位语从句和定语从句有些困难，下面来谈谈这个问题。由于w/h-clause引导的同位语比较少，且容易辨别，其先行词只有question, problem, idea , doubt 等，这里我们主要谈that-clause .
* 从意义上看：同位语从句所表达的内容与其先行词所表达的内容可以划上等号。例如：
He heard the news that his team had won.
(the news=his team had won)
He came to the decision that he must act at once .
(the decision=he must act at once)
我们还可以这样讲，同位语从句能变为其先行词的表语从句：
The news was that his team had won .
The decision was that he must act at once .
而定语从句是修饰，限制，补充说明先行词的，先行词所表达的内容不能与定语从句所表达的内容划等号。例如：
Then news that appeared in the papers this morning was well received .
(the news≠that appeared in the papers this morning )
定语从句也不能变为先行词的表语从句：
The news was that appeared in the papers this morning .( х)
* 从that从句的语法功能上看：在同位语中，that 只是个连词，不充当句子的任何成分，而在定从中，that则必定充当一个成分（主语，宾语等）。请比较下面的句子：
The fact that the prisoner was guilty was plain to everybody . 同位
It is a question that needs every careful consideration.
定从，that作主语
* 从充当先行词的名词的特点上来看：充当定从的先行词是无限的，而充当同位语的先行词是有限的，是一些表达概括意义的抽象名词：assumption (假设), fact (事实), idea(想法)，news(消息，新闻)，belief(信念), message(信息), proposal(建议)，proposition(建议，主张)，evidence (证据，迹象), proof(证据)，possibility(可能性)， suggestion (建议)等，更多的能引导同位语的先行词参见“名词性从句大观圆”的相关部分。例如：
Theirs is a feeling in me that we’ll never know what a UFO is.
We’ll be there tomorrow on the the assumption that it doesn’t rain.
The suggestion that the new rule (should) be adopted came from the chairman .
Obviously there was little probability that they would succeed ,but they didn’t mind .
