名词性从句名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点，也是高考考查的热点。
一、名词性从句的分类名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
其连接词有that, if, whether；连接代词who, what, which；连接副词when, where, how, why等。
考查热点一：对主语从句的考查主语从句在复合句中充当主语，它可以放在主句谓语动词之前。
但为了保持句子平衡，多数情况下可用it作形式主语，而把主语从句置于句尾。
考查热点二：对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动make, find, see, think等，则把宾语从句置于宾语补足语之后，用it作形式宾语。
另外，某些作表语的形容词，如sure, happy, glad, certain 等之后也可以带宾语从句。
考查热点三：对表语从句的考查表语从句在句子中作表语，位于主句中的系动词之后。
一、什么是表语（predicative）在形式上，位于系动词后的就是表语。
从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分。
即是指“是”字句“是”字后面的成分。
表语就是起表述作用的句子成分。
它修饰的是主语。
表语是用来说明主语的身份、性质、品性、特征和状态的。
表语须和连系动词一起构成句子的复合谓语。
表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当，它常位于连系动词（be, become, appear, seem等）之后。
Albert Einstein was a famous professor of physics.二、不定式、动名词与分词作表语的区别不定式和动名词作表语相当于一个名词作表语，含义是回答主语“是什么”；分词作表语相当于形容词作表语，含义是回答主语“怎么样”。
名词性从句知识点汇总一、名词性从句的分类名词性从句，包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。
因为主语、宾语、表语、同位语这四种成分均可以由名词构成，所以这四种从句在主句中都充当了名词的作用，故将这四种从句统称为名词性从句。
如：1.That she will help me made us happy.（主语从句）2.I can understand what he said.（宾语从句）3.This is where I was born.（表语从句）4.The fact that a heavy earthquake happened made me crazy.（同位語从句）二、名词性从句的连接词分类1.that（无含义，不充当成分）2.whetherif（有“是否”的含义，但不充当成分）3.连接代词：what whatever who whoever whom whomever whose which whichever.（在从句中做主语、宾语、表语和定语）连接副词：when whenever where wherever how however why （在从句中做状语）4. as ifas thoughbecause（不充当成分，在名词性从句中只引导表语从句）三、连接词that在名词性从句中可以省略的三种情况1.it 做形式主语，that引导主语从句时It is said (that) he has been studying abroad.据说他一直在国外学习。
2.动词后面的宾语从句中I think(that) you have much to improve in English.我认为你的英语需要提高的有很多。
3.形容词后面的宾语从句中I am afraid (that) I will be late.恐怕我要迟到了。
四、同位语从句和定语从句的区别that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。

实际上就本题而言，不难看出句意为“玛丽写了一篇关于队伍为何在比赛中失败的文章”，所以应该选用强调原因的why。
2. Dam left a word with my secretary he would call again in the afternoon.A. whoB. thatC. asD. which[专家把脉] B 本题考查同位语从句，that只起引导词的作用，不充当任何句子成分。

He told me（that）he would leave soon．2．what与that在名词性从句中的区别。
eg：What he said was true．这是一个主语从句，what在从句中作动词said 的宾语，意思是：“·…··话”或“……事”，此句中不能用that。
That he came late made the teacher angry．这个句子还是主语从句。
从句中意思完整，所以用that来引导，起到一个标志作用。
