　　在许多情况下，当语义上需要用一个较复杂的that从句用主语时，若直接将其置于句首位置，则会显得“头轻脚重”。这时，我们通常采用的办法便是使用形式主语it来改变句子结构。如：

　　That he had no girl friends worried his parents a lot.= It worried his parents a lot that he had no girl friends. 他没有女朋友，这件事使他父母非常不安。

　　That he has fully recovered makes me feel good.=It makes me feel good that he has fully recovered. 他已痊愈，真令我高兴。

　　That he had not said anything surprised everybody.=It surprised everybody that he had not said anything. 他一言不发，这使大家很吃惊。

　　用形式主语改变句子结构是许多同学都可能想得到的方式，属通常思维，乃常规表达。但如果借助the fact这一辅助手段，按以下方式改写句子，则会给人以耳目一新的感觉，许多阅卷老师会将其划入“高级结构”的范畴。如：

　　The fact that he had no girl friends worried his parents a lot.

　　The fact that he has fully recovered makes me feel good.

　　The fact that he had not said anything surprised everybody.

　　在句子中起名词作用的句子叫名词性从句 (Noun Clauses)。 名词性从句的功能相当于名词词组， 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

　　分类

　　引导名词性从句的连接词可分为三类：

　　连词(5个)：that (本身无意义。引导单一的宾语从句时that常可省略，但引导主语从句、表语从句、同位语从句时that通常不被省略)

　　whether,if (均表示“是否”表明从句内容的不确定性)

　　as if ,as though (均表示“好像”，“似乎”)

　　以上在从句中均不充当任何成分

　　连接代词(10个)：what, whatever, who, whoever, whom, whomever, whose,whosever, which, whichever

　　连接副词(7个)：when, where, how, why, whenever, wherever, however

　　不可省略的连词：

　　1. 介词后的连词。

　　2. 引导主语从句和同位语从句的连词不可省略。

　　That she was chosen made us very happy.

　　We heard the news that our team had won.

　　3. 在从句中做成分的连词。

　　比较

　　whether与if 均为"是否"的意思。 但在下列情况下，只可用whether：

　　1. whether引导主语从句并在句首。

　　eg:Whether he can come to the party on time depends on the traffic.

　　2. 引导表语从句。

　　eg:The question is whether we can get in touch with her.

　　3. whether从句作介词宾语。

　　eg:I am thinking about whether I should quit my present job.

　　4.if与whether都可以与or not 连用，但后面紧跟or not 时只能用whether。

　　We didn't know whether or not she was ready.(此时只能用whether)

　　I wonder whether/if the news is true or not.(此时则二者都可以用)

　　5.后面直接跟动词不定式时。

　　6.引导同位语从句时。
