名词性从句指的是在主句中起的作用相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。
一、主语从句
1．引导主语从句的连接词：从属连词that, whether/if；连接代词what, who, whom, whose, whatever, whichever, whoever等；连接副词when, where, why, how, whenever等。

2．主语从句一般放在句首，但有时也可用it作形式主语，而将主语从句移到句子的末尾。常见的句型：
(1)It＋be＋形容词(necessary/likely/important/uncertain等)＋that从句
(2)It＋be＋名词(短语)(a pity/a shame/no wonder/no surprise等)＋that从句
(3)It＋be＋过去分词(said/reported/decided/believed等)＋that从句
(4)It＋不及物动词(seem, appear, happen等)＋that从句

2．it作形式宾语的宾语从句

他清楚地表明会议不会被推迟。
(2)动词hate, like, dislike, appreciate, enjoy等表示“喜欢”、“厌恶”的动词以及一些动词短语see to, depend on, rely on等常用it作形式宾语，而将宾语从句后置。

三、表语从句

浓雾覆盖着整座城市。好像把一个巨大的黑色的毯子扔到它的上面。
3．because, why引导的表语从句
because, why也可引导表语从句，但because引导的表语从句，主语不能是reason或cause (该结构常用that引导)。常用于以下句型：
①China is developing fast. Thats why I think those of my colleagues who deal with China affairs should visit China.

②The reason why he didnt pass the exam was that he was too careless.

Ⅰ.语法填空
(2016·东北三省三校一模)The “selfie” is used to describe the selftaken photo, often from a smartphone. Someone takes about 10 selfies each time he does, and he only ends up __1__ (post) one or two of those.

语篇解读：很多人会把自己满意的自拍照发到网上去，他们认为这样可以使自己增强爱自己的决心。1．posting 考查非谓语动词作宾语。end up doing sth.为固定用法，意为“以……而结束，最终做了某事”。
2．best 考查形容词最高级形式。由语境可知此处表示从众多自拍照中选一张自己认为最好的，由此判断此处应用good 的最高级。
3．is removed 考查时态和语态。由语境可知应用一般现在时，又因remove与everything为被动关系，故用一般现在时的被动语态。
4．determination 考查名词。give sb.sth.“给某人某物”。又根据设空处前的the 也可判断设空处应用名词。determination为不可数名词，后面常用不定式作定语。
5．a 考查冠词。设空处的poem为可数名词，在本句中表泛指，故与不定冠词连用。
6．what 考查宾语从句。所填词在宾语从句中作宾语，故应用what。
7．myself 考查代词。由空前的I及语境可知设空处用反身代词。
8．no 考查倒装句式。根据本句中“am I saying”的倒装语序，可推知设空处应为否定词。表示否定意义的介词短语放在句首时，后面的主谓部分常用部分倒装形式。in no way “决不”。
9．to 考查介词。a gateway to ...为固定搭配，意为“通向……之路”。
10．However 考查副词。前后句之间是转折关系，并由后面的逗号可知应填However。
