怎样分清定语从句和同位语从句
怎样分清定语从句和同位语从句
怎样分清定语从句和同位语从句
1、一般说来,定语从句的先行词由名词或代词组成,同位语从句的先行词一般都是名词：
those who want to go please sign their names here.(定语从句)
we express the hope that they will come to visit china again.（同位语从句）
2、定语从句修饰、限定先行词的意义,与先行词为修饰关系；同位语从句说明先行词的具体内容,与先行词是同位关系.
the train that has just left for beijing.
the truth that the earth moves around the sun is known to all.
3、定语从句由关系代词或关系副词引导；同位语从句主要由连接词that 引导,有时也可用where,who whether引导.
do you know the place where he was born?
then he raised the question where they were to get the machine needed.
4、引导定语从句的关系代词往往可以省略；引导同位语从句的连接词一般不可以省略
the news (that)he told me is exciting.
the news that he has been elected president of the USA is true.
5、同位语从句与先行词一般可发展成为一个完整句子,谓语动词用to be
he heard the news that his team had won.
改为：
the news was that his team had won.
定语从句一般的先行词在从句中一般充当主语宾语与定语，有固定含义，而同位语的先行词不充当任何成份，而只是对这个名词起解释说明作用，且先行词可固定为advice . Attention . …等
就是一个句子，在句子中的结构我总是分不清，我不知如何分清它是作主语主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句
定语从句的that在从句中充当成分，同位语从句的that不充当成分，只起连接词的作用。
