这篇SAT语法笔记是关于SAT语法中的陈述句的，陈述句可分别充当四种句子成分(名词从句的重点内容)，对于陈述句，我们要在句首加上that,然后把“that+陈述句”分别放在另一个句子的四种位置：主语、宾语、表语和同位语，即构成四种名词从句。

　　1，主语从句。“that+陈述句”在主语位置即成主语从句：

　　Stuart is ugly。

　　That Stuart is ugly is a fact.。

　　That Malaysians don’t speak good English is obvious。

　　更常见的是用it式主语置于句首，而将主语从句放在句末。例如：

　　It is a fact that Stuart is ugly。

　　It is obvious that Malaysians don’t speak good English。

　　因此下面都是常见的主语从句句型：(￥)

　　①It is +过去分词 +that 从句(found, believed, reported, thought, noted…)

　　②It is +形容词 +that 从句(clear, possible, likely, natural, certain, fortunate, necessary, strange…)

　　③It is +名词(短语) +that 从句(a pity, a shame, an honor, a good idea, a miracle…)

　　2，宾语从句。“that+陈述句”在宾语位置即成宾语从句：

　　I think (that) you turned off the light。

　　We know (that) women love shopping。

　　She believed (that) her child was premature。

　　只有宾语从句中的that才可以省去，其他名从that不省。

　　3，表语从句。“that+陈述句”在表语位置即成表语从句：

　　My idea is that the students should be more open to each other。

　　The reason is that he was careless and irresponsible。(考点)

　　4，同位语从句。“that+陈述句”在同位语位置即成同位语从句：

　　所谓同位语，就是用来补充说明名词的成分。

　　The rumor that Tom washed his socks once a month turned out to be untrue。

　　Our fathers brought forth upon this continent a new nation, conceived in liberty and dedicated to the proposition that all men are created equal。

　　A saying goes that tomorrow is another day。
