复习名词性从句作主、宾、表概念引入名词性从句包括主语从句、表语从句、宾语从句和同位语从句，其功能相当于名词。
综观近几年的高考英语试题，名词性从句是必考项之一。

先看下面句子：1. That is why today over 40% of Californians speak Spanish as a first or second language.2. It is believed that before long the mix of nationalities will be so great that there will beno distinct major racial or cultural groups, but simply a mixture of many races and cultures.3.

考点四 同位语从句同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。
1．常见的后跟同位语从句的名词有：advice 建议conclusion 结论 demand 要求 doubt 怀疑fact 事实hope 希望 idea 主意information 信息 message 消息 news 消息order 命令 possibility 可能性 promise 诺言question 问题 request 请求 suggestion 建议 thought 想法 plan 计划①I made a promise to myself that this year ，my first year in high school ，would be different.我对自己承诺：今年，我高中的第一年，会有所不同。
②(2016·天津高考)The manager put forward a suggestion that we should have an assistant.There is too much work to do.经理提出了我们应当有一位助手的建议。
要做的事情太多了。
2．引导同位语从句的连接词有：that，whether，how，where，when，why 等。
①Evidence has been found through years of study that children's early sleeping problems are likely to continue when they grow up.通过多年的研究发现：有证据表明孩子的早期睡眠问题很有可能会随着他们的成长继续下去。
②She asked a question why there was a delay.她问了发生延误的原因。
③I have no idea when he will come back home.我不知道他什么时候回家。
[名师点津]在同位语从句中，that，whether不作句子成分。
that无实义，whether意为“是否”，if一般不引导同位语从句。
引导同位语从句的连接词一般都不能省略。
[易错警示]引导名词性从句时，that没有词义，在从句中不作任何成分。
当从句意义完整，不缺任何成分时，往往选用that；而what引导名词性从句时，意为“什么”或“……的”，在从句中用来作主语、表语或宾语。
