The problem whether we should continue to do the experiment has been solved. I have no idea when he will come back. ;1.同位语从句说明的名词大都是抽象名词; 定语从句所修饰、限定的名词或代词有抽象的也有不抽象的。;2. 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);3.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.;4.同位语从句的简易判断方法：同位语与其先行词之间在逻辑上是“主语+be+表语”的同位语关系。所以，可以在名词从句之间加系动词be，使之构成一个新句子，如果合乎逻辑，句子通顺，则原句为同位语从句；定语从句是不能够有系表结构把先行词与从句连接起来的。The belief that the earth is flat is still held in some countries. →_______________________________ .;同位语从句有时被别的词把它和名词隔开：;1.

A warm thought suddenly came to me ____I might use the pocket money to buy some flowers for my mother’s birthday. (2006 安徽) A. if B. when C. that D. which;3.
