Revise of Noun Clause名词性从句 在句子中起名词作用的句子叫名词性从句. 分为: 主语从句(subject clause) 宾语从句(object clause) 表语从句 (predicative clause) 同位语从句(appositive clause) 引导名词性从句的连词和连接代词 注意引导词与定语从句的引导词的区别 what 能引导名词性从句，并作宾语\主语 不能引导定语从句 that 在名词性从句中没有成份，只作标志 eg: I knew that I was wrong. 在定语从句中 作宾语\主语 eg: I get the very news that is important to me. which 在名词性从句中加上名词做主语\宾语 eg: I don’t know which answer is right. 在定语从句中，单独做主语\宾语 eg: I see a film which was popular in the past. 名词性从句的基本要求：Pay attention 时态 :(与间接引语基本一致) 如果主句是现在时，从句时态可以不变，但如果主句是过去的时态，那么从句的时态一定要用相对应的过去的某种时态。当从句是客观真理,定义、公理、定理时用一般现在时。 宾： I know he lives here. He asked whether his father would come back. The teacher said that the earth travels around the sun. 表：That is what I was worried about two days ago. It looked as if it was going to rain. 语序：要用陈述语序 1. Mary wrote an article on___ the team had failed to win the game. A. why B. what C. who D. which 2. Can you make sure___ the gold ring?

B) 后面直接跟动词不定式时。如： 　 He doesn’t know whether to stay or not. C) 后面紧接or not 时。如： 　 We didn’t know whether or not she was ready. 其他从句只用whether的情况： D)在表语从句和同位语从句中。如： The question is whether the film is worth seeing. The news whether our team has won the match is unknown. B) 在主语从句中，只有用it 作形式主语时, whether和 if 都能引导主语从句, 否则, 也只能用whether如: Whether we
