Grammar(1)名词性从句
在复合句中起到名词作用的从句叫名词性从句，包括主语从句，表语从句，宾语从句和同位语从句。引导名词性从句的词有：连词that，whether，if；连接代词和连接副词what,which,who,whom,whose,when,where,why，how等。
名词性从句可以表示两方面：一个事实，一个问题。问题又分两方面即一般问句和特殊问句，请看下图：

一、主语从句就是做主语的从句。它由that和其他疑问词引导。
1．Thattheyarerichistrue,isn'tit?(that不能省略)
2．Wherehegotitisunknowntous.
3．Theylosttheirwayinthewoods,andwhatmademattersworsewasthatnightbegantofall.
4．Whoeversaidthatwaswrong.
5．____________________________________________(地球围绕太阳转)isatruth.
6．_____________________(任何努力学习的人)willpasstheexam.
7．_____________________(我所告诉你的)justnowwaswhathadbeenwrittenintheletter.
8．________________________________________________(我是接受礼物还是拒绝它)isnoneofyourbusiness.
有时用it作形式主语，而把真正的主语从句移到后面。其句型有：
a.It+be+形容词+that-从句
Itisnecessary/importantthat…有必要/重要的是……
Itisobviousthat…很明显……
b.It+be+-ed分词+that-从句
Itisbelievedthat…人们相信……

c.It+be+名词+that-从句

d.It+不及物动词+that-分句
