考研英语同位语从句识别

在考研英语中，同位语从句在句中有两种位置：要么紧挨着所解释的名词，要么跟所解释的名词之间有其它成分。那么同位语从句到底应该怎么识别呢，一起来看看！

同位语从句前面只能是idea，fact，hope，news等抽象名词，而定语从句的先行词可以是名词(多是详细名词)、代词，主句的一局部或是整个主句，如:

The possibility that the majority of the labour force will work at home is often discussed.(同位语从句)

Our team has won the game， which made us very happy. (定语从句)

定语从句是从句对其先行词的修饰或，属于形容词性从句的范畴;而同位语从句是从句对前面抽象名词的进一步的说明和解释，属于名词性从句的范畴，如:

The news that our team has won the game was true. (同位语从句，补充说明news到底是一个什么消息。) The news that he told me yesterday was true. (定语从句，news在从句中作told的宾语。)

有些引导词如how， whether， what可以引导同位语从句，但不能引导定语从句，如:

That question whether we need it has not been considered.

我们是否需要它这个问题还没有考虑。(同位语从句)

引导词that引导定语从句时，在从句中一般作主语或宾语(指物时还可以用which代替)，并且作宾语时常常省略，that在同位

语从句中仅起连接作用，不充当任何成分，并且不能省略，也不能用which来代替，如:

The order that we should send a few people to help the other groups was received yesterday.

我们应派几个人去帮别的几个小组的命令昨天收到了。(同位语从句。是对order的详细解释，that虽不作成分，但不能省略。) The order that we received yesterday was that we should send a few people to help the other groups.

我们昨天收到的命令是我们应该派几个人去帮助别的几个小组。(定语从句，是名词order的修饰语，that在从句中作received的宾语，可以省略。)

These leaders are living proof that prevention works and that we can manager the health problems that e naturally with age.

大家来分析下，看看三个that分别引导的是什么从句。分析出来了吗?前面两个that引导的是同位语从句，最后一个that引导的是定语从句，that在定语从句中做主语。
