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。

被强调部分指人是也可用who/whom。
例如：It is a pity that you didn’t go to see the film.It doesn’t interest me whether you succeed or not.It is in the morning that the murder took place.It is John that broke the window.2. 用it 作形式主语的结构(1) It is ＋名词＋从句It is a fact that … 事实是…It is an honor that …非常荣幸It is common knowledge that …是常识(2) it is ＋形容词＋从句It is natural that… 很自然…It is strange that… 奇怪的是…(3) it is ＋不及物动词＋从句It seems that… 似乎…It happened that… 碰巧…(4) it ＋过去分词＋从句It is reported that… 据报道…It has been proved that… 已证实…3. 主语从句不可位于句首的五种情况(1) if 引导的主语从句不可居于复合句句首。

从句(Clause)
If two numbers are to be added, it does not matter in which order they are added. 若要把两个数加起来，那么按哪种顺序相加是没有关系的。(需要注意的是，连接代词which并没有位于主语从句句首， 因为它在从句中作介词in的介词宾语和order的定语。而且，不要把由which引导的主语从句误认为是介词宾语从句。) It follows from Maxwell’s hypothesis that whenever there netic field is produced. 由麦克斯韦假设可知，每当电场发生变化时就产生磁场。 (it follows that … 意为“由此得知……；因此”。) It happened that she was out when he called.( = She happened to be out when … ) 他打电话时，她恰巧不在家。(It happens that可译成“碰巧，恰巧；发生”。)
