　　Grammar：同位语从句

　　同位语从句是英语中的四大名词性从句(主语从句、表语从句、宾语从句和同位语从句)之一，它不仅是高考的重要考点之一，也是阅读中经常遇到的语法现象。

　　考点一：同位语从句的概念和类型

　　在主从复合句中，用作同位语的从句叫同位语从句。同位语从句一般跟在某些名词的后面，用以解释或说明前面的名词的内容。经常带同位语从句的名词有fact，news，answer，message，doubt，possibility，idea，reply，reason，belief，hope，thought，promise，suggestion，question，certainty等。引导同位语从句的词有that，whether以及连接代词who，which，what等和连接副词where，when，why，how等。

　　1)由that引导的同位语从句。此时的引导词只起连接作用，不在从句中作任何成分。

　　The news that more than 1,000 people were killed in the mudslide made us sad.

　　一千多人在泥石流中丧生的消息使我们感到难过。
