名词性从句考点及易错点归纳总结考点：关系词的选用原则：缺啥补啥，补缺用连接词或连接副词，具体选择看句意易错点：1.名词性从句关系词的省略问题：除了宾语从句可以省略that关系词外，其他的都不行。
另需注意宾语从句如有两引导词that，则第一个可省，第二个不可。
2.主语从句及宾语从句常考的几个形式主语\宾语结构（一）it作形式主语的常见句型：(1)It＋be＋形容词(necessary/likely/important/certain等)＋that从句(2)It＋be＋名词(短语)(a pity/a shame/no wonder等)＋that从句(3)It＋be＋过去分词(said/told/reported等)＋that从句(4)It＋不及物动词(seem，appear，happen，matter等)＋that从句（二）形式宾语宾语一般放在及物动词或介词之后，但是，在下列情况下，须用it作形式宾语，而将真正的宾语(常为不定式/从句)后置。
(1)动词find/feel/think/consider/make＋it＋宾补(形容词或名词)＋不定式/从句(2)动词hate/ like/ dislike/ appreciate/enjoy＋it＋从句(3)短语动词see to/ depend on/rely on＋it＋从句(4)固定搭配take it for granted that/owe it to sb.that＋从句3.if 与whether 的异同只用whether的情况：（1）主语从句位于句子开头（2）介词后的宾语从句；（3）引导表语从句或同位语从句；（4）与or not连用；（6）与to do 连用3. 语序问题：含有疑问意思的语序用陈述语序4. 时态问题：与主句保持一致，但客观真理需用一般现在时。
5. 名词性从句的虚拟语气问题→that sb (should) do6. 其他常考的表语从句(1)This/ That/ It is why＋表语从句(表结果)“这/那就是……的原因”(2)This/ That/ It is because＋表语从句(表原因)“这/那是因为……”(3)The reason why...is that＋表语从句“……的原因是……”7. 同位语从句与定语从句的区分同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。
定语从句则是对于从句中的某一名词进行修饰。
常见同位语从句的名词：advice，conclusion，doubt，fact，hope，idea，news，promise，question，suggestion，thought，truth，wish，word等。
引导同位语从句的引导词：that，whether，how，where，when，why等。
