6、可以引导主语从句,但nomatterwho,nomatterwhat等不能.4.为避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语.Itiswellknown/reported/thought/said/…that…Itisclear/necessary/certain/doubtful/…that…周晨——名词性从句Itisapity/ashame/anhonour/…that…Itdoesn’tmatterwhether…/Itseemsthat…Ithappensthat…※it作形式主语和it引导
7、强调句的比较It作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分,都可用连词that。被强调部分指人是也可用who/whom。例如：Itisapitythatyoudidn’tgotoseethefilm.Itdoesn’tinterestmewhetheryousucceedornot.Itisinthemorningthatthemurdertookplace.ItisJohnthatbrokethewindow.※用it作形式主语的结构(
