　　拓展

　　1同位语从句

　　在复合句中用作同位语的从句叫同位语从句，常常跟在fact,idea,opinion,news,hope,belief等名词后面,用以说明该名词表示的具体内容，可以由名词、代词、短语及句子来充当同位语从句。

　　同位语从句是名词从句,其作用相当于一个名词,对前面抽象名词的进一步的说明和解释。

　　2定语从句

　　定语从句是由关系代词和关系副词引导的从句，用来修饰名词或代词，起到定语的作用，所以叫做定语从句。定语从句的作用是作定语修饰主句的某个成分，通常分为限定性和非限定性从句两种。

　　定语从句不同于单词作定语的情况，它需要放在被修饰的词（即先行词）之后，一般由关系代词来引导，关系代词必须放在定语从句之首。被修饰的词叫先行词，由关系词（关系代词或关系副词）引出。

　　3同位语从句与定语从句的区别

　　1、引导同位语从句的that是连词,在从句中不充当任何成份,而引导定语从句的`that是关系代词,除起连接作用外,还在从句中充当主语、宾语或表语等，如：

　　The idea that computers can recognize human voices surprises many people.

　　计算机能够识别人的声音的想法使许多人感到惊奇。（同位语从句，that在从句中不充当任何成份）

　　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）

　　2、引导词的不同

　　what,how,if,whatever等可引导名词性从句，但不引导定语从句。

　　3、同位语从句与前面的名词是同位关系,即说明它前面名词的内容；而定语从句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。如：

　　The news that l have passed the math exam is true．我通过了数学考试这一消息是真的。

　　（同位语从句,即从句所表达的意思就是前面名词的内容）

　　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,从句对前面名词起修饰限制作用,即“他告诉我的”那个消息,而不是别的消息）

　　4、定语从句的先行词是名词或代词；而同位语从句的先行词只能是名词，而且仅限于idea，fact，hope，news，doubt，truth，information，suggestion，question，belief，conclusion等少数名词。而且when，where，why引导的定语从句的先行词一定分别是表示时间、地点和原因的名词，而三者引导的同位语从句的先行词则肯定不是表示时间、地点和原因的名词。I have no idea when they will come.我不知道他们什么时候来。(同位语从句)

　　I’ll never forget the days when I lived there.我永远不会忘记我住在那儿的日子。(定语从句)
