(同位语从句)those who want to go please sign their names here. (定语从句) 同位语从句所说明的名词与从句没有逻辑关系；定语从句所限定的名词是从句逻辑上的主语、宾语、表语、定语、状语等。the news that they won the match is true.(同位语从句, news 和从句没有逻辑关系)the news that you told us yesterday is true.(定语从句, news 是 told 的逻辑宾语) 同位语从句主要由连接词that引导,有时也可用when, where, who, whether等引导; 定语从句由关系代词或关系副词引导。then he raised the question where they were to get the machine needed. (同)do you know the place where he was born?(定)同位语从句与先行词一般可变成一个完整句子, 谓语动词用be的不同形式。 he heard the news that their team had won. 此句可以变为一个表语从句: the news was that their team had won.从引导词来看: 引导词that在同位语从句中是连词, 只起连接作用, 无具体词义, that不可省略; that在定语从句中是关系代词，它在从句中充当一定成分主语或宾语有具体词义, 作宾语时还可以省略。例如： a) the factory _ we visited yesterday is a chemical one. b) the news _ he will leave for shanghai is true.step 5homework完成步步高p29页巩固落实。主备教师：张黎 选修8 unit2 cloning period four using language goals: 1.activate the ss to show their opinions about the cloning2. enable the ss to write and article on this debate. 一 before class完成步步高自我探究。page30-33.二
