疑问词+to do adj 作为名词Verb phrasePrep. phrase同位语从句
简单地说，同位语从句就是后面那句话是前面这个名词的具体的内容。
比如说：我有个通知：明天放假。
( I have a notice that tomorrow is free. )
这句话中, tomorrow is free 就是 notice 的具体的内容,是同位语从句。能用于同位语从句前的名词有：
ability, patience, anxiety, answer, order, report, wish, decision, suggestion, belief, doubt, fact, hope, message, news, promise, question, reply等等。同位语从句与that引导的定语从句的区别：1、同位语从句与名词之间在逻辑上是“主语+be+表语”的关系。该名词是需要做特殊说明的抽象名词。例如：
a) 听说他们的队赢了，他们很高兴。
_______________________________________
_______________ .
b) 消息就是他们队赢了。
_______________________________________.They were delighted at the news that their team had wonThe news was that their team had won2、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.(that)that定语从句同位语从句3、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。例如：
The belief that the earth is flat is still held in some countries.
→_______________________________ .The belief is that the earth is flatAlong with the letter was his promise ____ he would visit me this coming Christmas. A. which B. that C. what D. whether解析：这是一个同位语从句，解释promise的具体内容，要用that引导。考试往往这样考：2. There is a new problem involved in the popularity of private cars ____ road condition need ____ . A. that; to be improved B. which; to be improved C. where; to be improved D. when; improving解析：That引导同位语从句说明“新问题”的内容。Need后既可接动名词的主动式，也可接动词不定式的被动式作宾语。3. There’s a feeling in me ___ we’ll never know what a UFO is – not ever.
A. that B. which C. of which D. what解析：同位语从句that we‘ll never know what a UFO is – not ever作a feeling的同位语，解释a feeling 的具体内容。That连接同位语从句时，只起连接作用，不作从句的任何成分。4. Information has been put forward ___ more middle school graduates will be admitted into universities.
A. while B. that C. when D. as解析：That引导从句作information的同位语，解释information的具体内容。5. These wild flowers are so special that I would do ____ I can to save them.

C. which D. whichever 解析：do后接宾语从句，宾语从句I can 后省略了do，缺少宾语。Whatever在宾语从句中作宾语。实战演习:
